Military Biofuels Ban Moves Forward, Ignites Criticism, Backlash

Meg Cichon, Associate Editor, RenewableEnergyWorld.com
June 06, 2012  |  71 Comments

As a proposed ban on military investment and use of biofuels inches closer to fruition in Washington, several groups are speaking out against the bill.

Pentagon Budget Bill, H.R. 4310, which recently passed through the Senate Armed Services Committee with a 13-12 vote and the House with a 299-120 vote, blocks the military from purchasing and investing in biofuels if they are more expensive than fossil fuels. The bill also exempts previous restrictions on liquid alternative fuels derived from coal and natural gas, which emit more carbon than traditional fossil fuels.

A coalition of 13 aviation groups have banded together to protest the decision, claiming in a letter to the Senate Committee that the bill would severely damage the advancement of the biofuels industry and hinder American energy independence. The coalition also argued that further investment in bioenergy will help reach their fuel efficiency and carbon emissions targets, which include a lofty goal of a 50 percent reduction in carbon emissions by 2050 from 2005 targets.

“We believe the ongoing military and civil aviation efforts must be continued and we strongly advocate that you prioritize and fund investment in aviation biofuels in what we all acknowledge is a difficult fiscal environment. Ultimately, we are convinced that this is an investment that will pay off by saving taxpayers millions through achieving energy security and independence.”

Liberal-activist group CREDO Action has also started a petition addressed to Republican Senators and Representatives to stop the bill from moving forward.

“It is outrageous that Republicans are working to block the military from developing biofuels that will save lives and save money. Stop protecting Big Oil's profits at the expense of our troops and our national security,” the petition reads. “Republicans love to talk about ‘supporting the troops.’ We need to remind them that that should mean our soldiers in harm's way, not oil industry lobbyists.”

U.S. Agriculture Secretary Tom Vilsack expressed his disbelief and frustration with the Committee’s decision during a conference call last week.

“It's beyond me why we wouldn't help this industry that will create higher farm income, more jobs in rural America, reduce the costs for consumers, satisfy commercial airlines ... and make our military less reliant on a foreign supply of energy,” said Vilsack. “It is just astounding that people don't understand that."

Vislack explained that the future of the biofuels industry is closely tied with the military, especially the Navy, and investments today will help bring down costs in the future – and costs have already come down. The Navy purchased biofuels in October 2010 at $424 per gallon, but paid $26.67 per gallon in December 2011, which will be demonstrated in a 50/50 blend of biofuel and petroleum that costs $15 per gallon during this month’s Rim of the Pacific Exercise in Hawaii. Though the industry is still very much in the research and development phase, prices cannot drop without continued support.

Said Vilsack, “Government has a role to work in partnership with the private sector to provide incentives, to provide the right tax policy, to provide assistance to get these industries up and going.”

ETCgreen: You are right. I stand corrected on my tone of voice. It is not an attack, and for the sake of our species and others I hope you are right. Our experiments are giving us hope that our larger scale solution is a new and fresh, fully benign solution. Algal biomass is one of the next best solutions. Thank you for your work, and wish you all the success in the world.

The military has a job of defending the freedom we have and eliminating imminent threats globally. Research done in a laboratory does not make "breakthrough" discoveries because of the stale thinking inside the walls. It is an archaic group of scientists that hold to the idea that "book knowledge" is going to produce the kind of results that occurred in the past by inventors working in the real world. The first "NEW" electric motor design in 100 years occurred a few years ago. The new design combined with cryogenic superconducting coils will produce an electric motor that is 98% efficient at variable speeds. If there is a market for a product there are private financing sources looking to invest. Fossil fuels are not going away for at least 2 possibly 4 decades. In the meantime renewable energy will begin to develop that makes leaps instead of tiny steps forward. Solar will continue to expand while energy efficiency will become a method everyone uses to manage their energy expense. Most of the scientists that I meet have a closed mind! The professors have closed minds and the students come out clones rather than voracious learners. We produce timid copy cats instead of ethical courageous geniuses ready to pursue truth and disruption. All of the problems associated with renewable energy are large. The US military has NO place in the development of energy technology: that is not their job.

All research laboratories are not able to make discoveries of the century for one reason, the monopolization of scientific discoveries. All free energies are not constant sources. Also dependent on the cost does not make them competitive with oil and gas. Ridiculous opening pioneers did it alone as an example of Leonard Divichi tank that could not budge because of his mockery of the scientist. At this time, everyone who is trying to pass a new free energy alone, no interest to them, besides the policy of this country prohibits out of bounds. Here is an example Tariel Kapanadze has a patent, is the free energy, no one does not need too low cost. The military took up the right thing, if the environment is in danger, so should help.

It does not matter what kgrossman thinks---or rather doesn't think. Fossil fuels are finite. One day, they will run out. There is no question about that. It is only a matter of time. We are already seeing it starting to happen. The only alternative is renewable energy.

@kgrossman I salute your positive attitude about our future, but having worked for the DoE and as a Researcher in university labs, I have to question the viability of your vision. I recently read a financial document on the amount of funds that had been spent on biofuels, solar, wind and geothermal R&D - world-wide. The numbers are small in comparison to R&D on military tech. Still, there are fewer and fewer "radical" breakthroughs in science and technologies today. An engineer entering the market place from college training typically looks forward to a 3-5% increase in efficiency, speed, etc., of one or two specific technologies over one's entire 40 year career. We know our plans are sure and steady as we will be able to produce a few billion gallons of biodiesel annually at $3/gallon when petroleum diesel will cost $5/gallon. So I will argue biodiesel will indeed stop many future resource wars. It is the only scalable, economically viable, environmentally friendly and truly sustainable replacement for petroleum we have on the table today.

Dependence on petroleum is a necessary burden. However, the application of science and economics will replace that burden with a new economy just as the horse and buggy were replaced by the automobile and the automobile will be replaced by personal aviation vehicles or all electric vehicles. Saddling the men and women who literally risk their lives with bullets and bombs all around is unconscionable. We the protected should carry that burden! Pathetic lazy science with irresponsible economics is 1 of the reasons that renewable energy is not moving forward. Another reason is that it has not matured enough to compete in the marketplace.

Pardon me but we are not supposed to inhale the "Pixie Dust!" Biofuels will NOT stop 1 war. War is part of the human condition and you are able to post comments because of the War of Independence. The economics of oil are a symptom to the corruption of the human spirit. Sex, power, and money have been the idols of mankind for millennium and wars are just expressions of wicked people who happen to have more influence than others. However, the USA, for the most part, has fought "Just Wars" where the goal was to end ruthless evil persecution or genocide: then we leave without the "spoils of war." Are you willing to do as you are told? Are you willing to lose any freedom to choose where and when you go or come? Are you willing to have some bureaucrat in a cubicle tell you whether you eat or not? Biofuels, solar, wind, and other renewable energy policy is a tiny miniscule issue in the grand scheme of things. Let's all chip in and get better science and reasonable economics into the mix so that we can help the military instead of adding another unnecessary burden.

If you REALLY want to save money on military expenditures---don't get into wars. Wars are the costliest endeavors in the world. The very best way that I can think of to stay out of wars is to convert our economy to biofuels and end our dependence on petroleum. The last three declared wars that the US has become involved in, along with numerous incursions and conflicts have had oil as an underlying cause. If you want to save money and lives---get rid of the use of petroleum.

@PuviAL I find it amazing that when I share my hands-on experiences with people on a renewable energy site, I receive such attacks. You are communicating with a 5th generation U.S. farmer who holds advanced college degrees, years of experience working for research universities, the DoE, DoD and Fortune 100 Corps. We are working orchards in 4 states and 2 foreign countries. Cliff claims he read through our website and then suggested we are working with micro algae. This is not correct. If you have ever put a gallon of petroleum sourced fuel in any tank you have burned ancient micro algae and we believe micro algae will be the primary source of energy within the coming decades, but we are growing orchards today - 4 varieties of trees. It is quite profitable - $38 barrel equivalent to petroleum. Join the Migration - http://etcgreen.com U.S. Migration

The military shows an example of how to preserve the environment destroyed. if military planners want it, they first went to work. Lord you want it poured out all alternative sources of energy dependent. Dependent, it means not constant as it comes to oil, gas and biofuels. The fact that for the "module" module runs continuously around the clock. His lack of its volume. If hydropower is a huge place in one area, then the module where it is going to demand. Increase in the number of modules, the thrust of energy, can reach a capacity of nuclear power. Price of the module assembly so funny that every farmer will collect in their own land.

I believe I said we should do it all. I believe if I know the cost of fuel at the airport then I would also know to get fuel before I am in that area. (Think ahead) There is plenty of fuel in the ground and in the water and all around the US. Regulations are what's keeping us from being independent. Before you go off on a tangent. The EPA, DOE, and DOA will be regulating the crap out of all the rest of the energy resources including your beloved biofuel. I never said that the military shouldn't use biofuels. You've mistaken me for someone else. I believe we should be researching & using any and every resource we have available. Not just one or the other. I really like the hydrogen thing too. The military doesn't need funding to do research on biofuels, DOA, DOE and several other agencies not to mention all of the companies and corporations out there do enough research that our tax dollars don't need to include defense also doing biofuel research. Now if one is okayed for use then by all means they should use it if it is cost effective. To use alternative energy such as the methane you so cleverly talked about earlier makes since if you want to use it to power a city that creates it. But you can't beat a Nuclear Powered Aircraft Carrier with poop.

-----" Sort of like the regular gas price being $3.56 then go out near the airport and its $5.56. Are you gonna go out of your way to purchase gas at the airport?"------- If your gauge is setting on empty, I'd recommend that you either buy gas at whatever the price----or you may end up having to take the bus. Right now, going out of our way to purchase petroleum means going to the Middle East, the arctic, or six miles under a mile of water. And that is running out---it is getting more expensive, quickly, and is only going to keep going up in the long run. The price of biofuels is higher right now---but we can always make more biofuels. And the more we make, the lower the price will become. Include the price of the military presence needed to secure and maintain petroleum supplies from the Middle East---and biofuels are already a bargain. Nobody knows more about the military cost of maintaining a standing army, navy and air force than the Department of Defense. Why do you think they are interested in biofuels in the first place? You may be good at pinching a penny till you get Old Abe to holler----but I don't think you are very good at long range planning.

etcgreen: What makes the sky green on your planet? It's not dollars, is it? Are research dollars the same green or greener? Just trying to tone-down the rhetoric. Hope you think that's funny. I'm not familiar with yoru figures. It seems a little optimistic, if true; there is no need for research money needed, nor for military support. Biofuels seem to be too much of a load on land, water, and energy resources. Not that we can't make them, but feeding our planes and tanks will crowd-out a lot of people's food needs from the planet. If I take off my skin, the surface of my body is green too. I don't often do that because it embarases people though. I've just finished a book on a replacement technology that makes the planet more verdant (greener), and cooler (more blue) at the same time it provides for our water, land, and energy needs. Your heart seems to be in the right place, but your science might need a little adjusting. There is no limit on energy on the planet, and so there is no limit on cycling of fresh water, and we have destabilized all biomes by using only 9 to 11% of the land for human uses. By putting on the little twist that we suggest, we can accomodate twice the current 7 billion comfortably and still make a more verdant world. But bio-fuels are just the wrong way, our technology produces excess di-hydrogen (h2-free) and oxygen (o2), so biofules will be practical for the next 10s of 1000s of years for us but only with our technology. Is'nt that cool? Stay tooned.

Your a really smart fellow, consider what we are using at this time without the sarcasm. You apparently misunderstood what I said and meant. But that's okay. If you want to just use old ironsides we understand. I was just stating that if biofuels were more economical than say diesel at the time they are procurring fuel then by all means they should use it. But I guess it's better to purchase a biodiesel even if it costs more? Sort of like the regular gas price being $3.56 then go out near the airport and its $5.56. Are you gonna go out of your way to purchase gas at the airport?

Congress shouldn't dictate if agencies may invest in biofuel or not. The only concern should be that agencies purchase the most economical fuel. The cost should be the most important at this time. If biofuels are cheaper then purchase them if not then don't. We should be using all avenues of energy sources, biofuels, hydro, solar, wind, tides, fossil etc. If governments and businesses in general really wanted to go green then it would be cheap. Solar panels would be $100, biofuel or grass gas would be .50 a gallon and on every corner. But it's not. It has to be more than just going green and reducing the carbon footprint to really make it in the world. Many say they care but they really like that escalade and starbucks while their on the way to the mall.

I would like to see the same policy applied across the board. Pentagon Budget Bill, H.R. 4310, applies to the purchase of bio-fuels, simply to be applied across all military purchases especially if it comes to space travel. This would mean that if we spend money on a future space travel project, a commercial flight would be priced and used as a (do not spend more than this). apply this policy to all military spending. not the ones that profit the oil industry that has so many paying special interest groups.

The strategic position of the U.S. military investment is defined from two perspectives. The first position, energy savings, the second position, the food program, in cases of disasters of nature. The question of farmers, where to get as much fresh water? Again, to buy oil and gas. Here is my project "Module Business Unit" will provide all the power of farmers.

-----" It costs a lot of money and energy to make an artificial ocean in the desert. "----- I've set up lots of aquariums. It didn't cost me a lot of money or energy. I've found that algae are not the least bit finicky about the conditions they can tolerate. In fact, they seem to tolerate just about anything. Ever tried to get algae OUT of an overgrown tank? It is next to impossible. You usually end up having to take the fish out, drain the tank, and wash down everything with bleach. It is like saying that dandelions are too fragile to get them to grow.

Here's some current data on micro-algae: - UVA lifecycle analysis of full 225 sq km or raceway ponds commercial scale found no hope for positive energy balance of algae biodiesel and net CO2 release during production (Clarens,et al. "Environmental Life Cycle Comparison of Algae to Other Bioenergy Feedstocks." Environmental Science & Technology 44, no. 5 (March 2010): 1813–1819.) - Takes 34-45 MJ of energy to make 27 MJ of algae biomass energy (Kloeck, Gerd. "It's the Process, Stupid. Biofuels from Microalgae Are Not yet Sustainable." Genetic Engineering and Biotechnology News, January 5, 2010.) - UT Austin Study ""energy required for water management alone is approximately seven times greater than energy output in the form of biodiesel and more than double that contained within the entire algal biomass." (Murphy, Cynthia Folsom, and David T. Allen. "Energy-Water Nexus for Mass Cultivation of Algae." Environmental Science & Technology 45, no. 13 (July 2011): 5861–5868.) BTW, even if cultured in salt water, algae requires huge amounts of fresh water for evaporation make-up, 3-10 mm a day for all the ponds (adding salt water would continuously increase the salinity and kill the algae.

@etcgreen. Okay, see on the website your feedstocks are jatropha and micro-algae. Here's something on the viability of Jatropha from Slade, et al. Energy from Biomass: The Size of the Global Resource (2011). UK Energy Research Centre, 2011. "The promotion of jatropha in Southern India – a cautionary tale: Jatropha is a hardy shrub promoted as potential source of biofuels on the basis of its claimed drought tolerance, suitability for marginal land reclamation and potential to support rural development. Assessing the performance of jatropha plantations in Tamil Nadu, India, Ariza-Motobbio et al. (2010) found that these claims were "too good to be true". Large inputs of water and fertilizer were required in order for the crop to be productive and yields were ~1/10th of those anticipated from research station trials. This rendered the crop economically unviable. The contribution to rural development was also questionable. The authors describe how the "pro-poor" rhetoric was used to build legitimacy for contract farming that only favoured resource rich farmers and further jeopardising the livelihoods of the poorest. Moreover, because there was no clear definition of the marginal lands to be developed, policies to prevent competition with agricultural land use were ineffective or subverted. Ultimately, the crop proved to be a poor fit with the ecological and socio-economic condition and ~70% of plantations were uprooted or abandoned." Looks like Jatropha is a water guzzler after all and field results don't live up to the snake oil salesman predictions.

@Fred. The Brazilians are finding out the hard way how wrong you are. Their crop yields are down 20% this year and they are IMPORTING 1 billion liters of ethanol. This is after they lowered their ethanol mixing ratio for gasoline in October because of the poor crop. They have been depleting their soil by harvesting crop after crop without sufficient fertilizer and herbicide and pesticide application, and it is catching up to them. Their EROI computation of 8:1 is really a computation of a different quantity called External Energy Ratio. They don't count all the bagasse calories they burn as an energy input that yields a far lower amount of liquid fuel calories (after trashing the air quality BTW). Properly computed EROI for Brazilian sugar cane is about 2:1, which is the same the US and EU get. There is no free lunch.

How can we research this magical enterprise you are running that requires no fossil fuel fertilizer (or pesticides or herbicides from fossil fuel) and virtually no water, and uses no electricity from the grid generated by fossil fuel, and which produces not only enough biomass, but enough surplus energy to process it into liquid fuel sufficient to power all the equipment, with enough left over to pay all the bills and still make a profit?

----" energy necessary to distill 'hol fuels will soon price them out of the range of viability as they all have a very low energy return - far less than 3:1 - actually closer to 1.1:1 and ~300gal/acre. "---- BTW---energy return on ethanol as produced in Brazil runs about 8 to 10:1. A much higher return on energy invested than petroleum according to the Argonne National Laboratory. According to Argonne---it takes 1.23 Mj of energy to produce 1 Mj of crude oil. And that is not all available as energy in the final product due to refining loses. And that number is going up steeply and rapidly as more and more oil is coming into the mix that is heavy, sour crude---or unconventional oils like tar sands, deep sea holes, or shale(which require considerably more work and energy to get out---as well as increasingly remote locations requiring longer and longer transportation routes).

The ash that remains after the bagasse has been burned is mixed with water to form a slurry and sprayed back onto the harvested fields as fertilizer. And that is all there is to it. Sugarcane is a grass---harvesting sugarcane is no different than mowing your yard---you don't plow, seed, irrigate, and so on every time you mow your grass. You just let it grow back again. There are cane plantations in the Caribbean area that have been in continuous production over 200 years.

---" We ran the numbers utilizing solar and wind and even natural gas (projecting costs forward over the next 20 years at large scale). The cost is extreme and simply is not viable."----- Hey, I'm not as stupid as I look. Don't be telling me that ethanol currently about $2.25 to $2.50/gal can't be competitive with gasoline at around $4.50/gal retail. Yes, there is a BTU content difference, it takes just a bit less than 3 gal of ethanol to equal two gallons of gasoline. This means 3 x $2.50 high end = $7.50 ethanol. 2 x $4.50 = $9 (average retail) $ .75/gal more for gasoline, equal BTU content ------" We ran the numbers utilizing solar and wind and even natural gas (projecting costs forward over the next 20 years at large scale). The cost is extreme and simply is not viable."------- It would be interesting to see your numbers. Solar power is low tech, easy to manufacture(you can make a very workable solar thermal collector in a garage workshop with junk parts----I've done it), easy to install, little to nothing to maintain, 100% efficient and the fuel costs nothing. Solar thermal power can easily attain temperatures suitable for use in a distillation application. The fuel is free. And thermal energy is cheap and easy to store. If you can't make that work...............you'd better just give up. In Brazil, they produce about 50% of their transportation fuel needs using ethanol made from sugarcane. The waste plant material after the juice is pressed from the cane is called bagasse. It is sun dried and burned to produce the energy needed to run the mills and distillation. There is enough electricity generated from burning the bagasse to provide all the energy needed by the mills---and still sell 25% to 30% of the energy generated back to the utilities by grid feed. And they have been doing it for about the last 20 years. (cont)

Gasoline engines(Otto cycle) are low efficiency because they are low compression---which is made necessary by using low octane gasoline as the fuel. Using high octane ethanol as a fuel allows the Indy racers to run a compression ratio of about 20 or 22:1----about twice that of a standard gasoline engine. I'm not against biodiesel or diesel engines at all---but it ain't the only trick in the sack either.

@Fred Regarding 'hol fuels (alcohol, ethanol, methanol, butanol, ...). Distillation is required - end of discussion - at best they can be additives or process chemistry for other higher BTU dense fuels - as with biodiesel. We have had this discussion in the past. Diesel engine vehicles blow the doors off of just about everything else on the track and on the road. You need to understand that $T's are being spent on a wide variety of transportation solutions rather than focusing on the one that will soon dominate. This increases the ultimate impact of the end of the Petroleum Era on all of our lives. Choose wisely. http://etcgreen.com/biofuel/audi-wins-le-mans-again

"------ It is not the use of biofuels that release GHGs---it is the use of liquid ammonia fertilizer produced from (fossil) natural gas that releases GHGs into the atmosphere. So, the simple lesson is, don't use liquid ammonia fertilizer produced from fossil natural gas. Use natural fertilizers instead. Such as leguminous plants or compost. Artificial fertilizer in the form of liquid nitrogen is highly toxic, dangerous and heroin for the soil. Go to the grocery store and get a bottle of household cleaning ammonia----open it up pour some on a cloth, hold it over your nose and mouth and take a big long whiff if you don't believe me. You'll see just how dangerous and toxic it is in one quick lesson---and I'll bet you won't forget that lesson for a long time to come. And that is only a 2-4% solution.

----" The point is that both are very high energy density fuels and it was quite inaccurate to disparage the energy density of gasoline."------ Energy density is useless if you can't use it. The octane rating of regular gasoline is about 85-87. This translates to a maximum compression ratio of 9.5 to 10:1 before preignition starts to occur. The octane rating of ethanol is ~115, this translates to a maximum compression ratio of 24:1. Compression ratio is the key efficiency with internal combustion engines. The higher the compression ratio, the higher the specific power output and the greater the thermal efficiency. A smaller engine will develop more power and go farther per BTU input with a higher compression ratio. This has been known and used to build smaller, higher power and more efficient engines for over a century. That is why the fastest, most advance race cars in the world, The Indy League Racing Circuit, use only 100% ethanol fuel. And they have used only alcohol based fuels for 50 years.

@Cliff Yes, we totally agree, all of these reports (some of which we authored), present the negative aspects of biofuels. Again, we actively lobby against most of the biofuel efforts on the planet today as they are 1st generation. However, you are throwing out the baby with the bathwater. Please take the time to understand the variables so you can understand the advantages of 2nd generation feedstock sourced biodiesel. The basic concepts are easy. 1. The crop needs to produce over 600 gallons per acre. 2. The plant needs to retain CO2 for over 100 years. 3. The crop needs to provide human food as well as fuel. 4. The energy conversion must be over 3:1. 5. Processor needs to produce their own methanol from renewables. Our projects exceed these requirements. Cliff - you seem to have some research skills. How about you use them for something worthwhile? Life is short - I will not respond to your posts again on this article. Regards.

Comparing HHVs of E10 Gasohol to B100 biodiesel in Argonne Nat'l Lab data, I find 33.6 vs. 35.3 MJ/L, so the scales are in favor of biodiesel by a small margin. I concede that biodiesel (FAME) has a slightly higher volumetric energy density, though it has a lower gravimetric density (per kg). The point is that both are very high energy density fuels and it was quite inaccurate to disparage the energy density of gasoline.

My role model probably more closely resembles Granny Clampett than Mother Jacobs. No one technology answers all problems everywhere. Biodiesel is good, but biodiesel does not work at optimum range in low temperature environments. CH4, by-passes this problem, since it is already a gas, there is no vaporization problems. ED95(ethanol diesel 95%) can also by pass the fuel gelling problem and vaporization problems. The correct answer is, the use of those fuels best suited to the usual or expected conditions of use, and multiple fuel capable engines. We already have them. In manufacture, on sale and in use on the road by consumers now---and have been for several years. If conversion of land use from food crops to biofuel crops is a worry----then use those biofuels that do not depend on the use of land based food crop suitable land. Or make use of agricultural waste. Less than 10% of what is grown is actually the usable part of a crop anyway. Even cotton, which is already a harvested crop---when it arrives at the gin, yields only 1 bale of lint for 4 that go in.

@Fred Enough petroleum supply to last until 2042? Depletion is not just a geological term, it is an economic term. While there are hundreds of billions of barrels of petroleum in tar sands and at the bottom of the oceans, the price to extract and refine this sour crude is the same price that will take a significant percentage of the world's population off the roads. The concept that people will still be purchasing gasoline in the year 2042 is ridiculous. We believe less than 50% of the fuel stations in the U.S. will still sell a product that is close to today's gasoline by 2020. You are likely driving your last gasoline powered car. Resource protectionism is alive and well and gaining influence. Over the next 5-7 years, you will see those nations with conventional petroleum reserves reduce their exports to save the resource for their own future use. Why pay $8 gallon for some flavor of low energy gasohol when you will be able to purchase a gallon of biodiesel blend for half the price? http://etcgreen.com Popular: Are you driving your last gasoline powered car?

@cliff-claven - Repeatedly you are citing documents that have been dismissed as their arguments are seriously flawed. I gave a lecture last year to a group of environmentalists who also argued about the burning of old growth forests for the planting of palm orchards. After I reminded the group palm is 1st generation feedstock and we actively lobby against the crop, I put up the logic equation: No Public Administration on burn clearing = biodiesel is bad? Hopefully you realize this a ridiculous argument and will stop citing it. To do so reflects very poorly on your ability to make your points. In a subsequent post, you are back on your misconception that petroleum is used in the production of biodiesel from 2nd generation feedstock. Again, this is false. We burn B100 in virtually all of our vehicles today and given another few years (we are working with the EPA Office of Transportation and Air Quality and expect to be able to remove the emission tech from our remaining vehicles) we will burn B100 in the remainder. Biodiesel is the only environmentally friendly, economically viable, scalable and truly sustainable replacement for petroleum we have today. I just took 10 minutes and found 20 university and government websites with a BTU energy chart for transportation fuels. All of them properly reflect that biodiesel offers 20-25% higher energy density over gasoline. Possibly you are confused about the label "gasoline"? Gasoline in the U.S. is virtually all 10% ethanol - more accurate to refer to it as gasohol. The evaporation factor of ethanol and gasoline makes this argue moot - billions of gallons per year are polluting our air. In a subsequent post you seem to be a proponent for EV's? Good grief, you need to read our articles on the subject - EV Tech - Postmortem and EV's and Hybrids are not our Future.

@ Kgrossman – "Any technological innovation that has a market will get funded by the private market." Yea – right. How did the market supply the missiles that we put on our jet fighters, or the internet, or etc, etc. Biofuels are past the science part and 'economics' don't just fall out of the sky. This is all about logistics. To quote Tom Hicks, Deputy assistant to the Navy for Energy, "… we are saying is that by 2012, to test the fleet and do the local ops that I mentioned with the Great Green Fleet, we need 8,000 barrels of biofuel. To deploy that in 2016, we need 80,000 barrels. Those are certainly quantities that – we have talked to industry – and they will have no problem with delivering. By 2020, we go from 8,000 to 80,000 to 8 million barrels, is what our need is to meet that goal of 50% alternative fuel. So if we were to sit passively back and not send out the demand signal, perhaps we would have a different outcome. We choose a leadership position, and part of that position is sending out a strong demand signal to the market, that if you can deliver this; if you establish this; if you can meet it at a competitive cost long-term, then this is something we are going to commit to." By 2020 they want price parity. That is a scaling of 10x, 10x, 100x, a typical scale up progression. Lets assume that every thing before parity averages a $20 premium. That is about 7.4 million dollars. You don't think the Navy can find this small amount if Congress would only let them? This is their priority and is a small amount.

Again as usual, most posts to this forum quickly move off the article topic. Etcgreen keeps telling us that we all need to buy diesel vehicles because that is our only future. Fred-lynn gives us his interpretation of 'Mother Jacobs Home Remedies' that may be mostly accurate but does not address the scale issue. Cliff-claven provides us with comic relief that we all loved in the TV program but that gets old here. Cliff has slipped in a valid point about water consumption. In studies on the energy/food/water nexus, water is divided into 'used' and 'consumed'. Fred, it is inappropriate to consider rainwater as consumed. Rainwater is largely just recycled to the next farmer. We all need to be concerned about those who don't have enough to eat and live without a good water supply, but we are not going to just pack them up and move them to the US or Brazil or pick your country. We are not going to capture our rainwater and ship it to them. And we should not feed them solely out of charity. We should not confuse their economic needs with our economic needs. Can we just talk about the article?

Solar energy is renewable. If you are using solar energy to make energy, it does not matter how much you use. Solar energy however, is not suitable for running tractors, trucks or supersonic fighter jets. Ethanol or camelina oil however is. They are solar energy in a mason jar. Captured and stored as chemical energy by the plants that the liquid biofuels were made from. Not only that, you are only counting a portion of the actual energy captured by the plants, be it corn, sugarcane, or camelina sativa. After you have produced the biofuel, you have DDG, bagasse or seed mash. DDG has MANY uses, both as an animal feed, and human, bagasse is dried and burned to generate electricity to run the mills at a net positive return that is fed into the electrical grid(in Brazil), camelina is a pioneer plant that grows well on marginal soils that are not useful or productive for food crops---it makes an excellent remedial and rotation crop for food crops such as hard wheat. In the natural world---using biofuels is no different in the Carbon Energy Exchange Cycle than using horses or oxen to do work, or even flying supersonic jet fighters. An F-18 flying on camelina oil is no different than an eagle, that is fueled by eating fish, that ate insects, that ate plants, that captured solar energy and stored it within the plant tissue. The natural Carbon Energy Exchange Cycle is an all encompassing closed circuit system that supports all life on earth. It is not a simple linear energy in, energy out pathway----it is a complex web of pathways that supports all living organisms on earth. It was developed and perfected over a period of hundreds of millions of years using field testing in the highest stakes competitive market of all---evolution.

If you waste the fossil fuels pouring them down the thermodynamic sinkhole of making biofuels, they run out sooner and everyone gets less net energy. The only sensible approach is to use fossil for fuel and agriculture for food. 30 sq m of mediocre 10% efficient solar panels produce the same energy in one year as the theoretical maximum ethanol that could be obtained from 10,000 sq m of switch grass (forgetting that switchgrass ethanol has a negative energy balance and costs more energy to make than it provides). Solar has not yet hit lifecycle break-even, but it is a far better place to be spending R&D money than on perpetual motion machines, which is what is attempted by converting natural gas hydrocarbons to ammonia-nitrate fertilizers to biomass carbohydrates and lipids and finally back to liquid hydrocarbons.

OK cliff---we'll have it your way and continue to depend on petroleum to meet our energy needs. We have plenty. At the current rate of consumption---we have enough to last until 2042. That is a long way off, 30 years. Of coarse, if the next thirty years are like the last thirty years, consumption will increase by about 5% per year. So, 30 years won't last thirty years. Maybe more like 20 years. Since we depend entirely on petroleum for food production, what are you going to eat in 20 years after the petroleum runs out? And, how will you drive to the grocery store to get it, and how will it get to the grocery store, and how will the farmers get the fields plowed, and where will the fertilizer come from, and so on, and so on...............

etcgreen: energy density of US formulated gasoline is 34.6 MJ/L while B100 biodiesel is 33 MJ/L, so do not understand your "low energy density" comment criticizing gasoline, unless you are really criticizing the otto cycle versus the diesel cycle, and even then efficiencies are not that far apart. Source of water footprint data is Gerbens-Leenes, W., A. Y. Hoekstra, and T. H. van der Meer. "The Water Footprint of Bioenergy." Proceedings of the National Academy of Sciences 106, no. 25 (June 3, 2009). Indonesia is planting oil palms where human food has never been grown, and they are burning millions of acres of peat lands to do it. They are now the third largest source of atmospheric CO2 behind the US and China (Lewis, Jonathan. Leaping Before They Looked: Lessons from Europe's Experience with the 2003 Biofuels Directive. Boston: Clean Air Task Force, October 2007.). If all tillable land in the world not needed for food was converted to biofuels, it would only supply one fifth of the current energy demand (Slade, Raphael, Robert Saunders, Robert Gross, and Ausilio Bauen. Energy from Biomass: The Size of the Global Resource. UK Energy Research Centre, 2011 [meta-study of 80 other studies]. Ten international aid organizations including FAO, IFAD, IMF, OECD, UNCTAD, WFP, the World Bank, the WTO, IFPRI and the UN HLTF have formally petitioned the G20 nations to drop their renewable fuel subsidies and fuel mixing mandates because of the impact they are having on driving up food prices around the world (Price Volatility in Food and Agricultural Markets: Policy Responses.

@Cliff-Claven Sorry to keep you waiting, I run a geo-diverse company that requires my attention from time to time. We have several years of experience with 4 types of 2nd generation feedstocks - depends on the area and climate. The water necessary for our main crops is about 1/3rd that of alfalfa. We only plant where human food has never been grown. Then again, 3 of our feedstocks provide human and animal food in addition to biodiesel. We make our own fertilizer - we have 52 mining claims on which we also raise cattle and one of our staff members (Ph.D. in Ag) contributes to the Global Phosphorus Research Initiative. No idea where you are getting your information about water requirements. Jatropha trees use only about 200 gallons of water per gallon of biodiesel, but almost none of this water is "lost". Agriculturally used water is just recycled over and over so your numbers are meaningless. When you burn biodiesel one by-product is water vapor out the tail pipe which returns to the atmosphere and falls as rain or is absorbed by the plant life around the roads. This is Ag 101 info. What is your background and agenda that you are attacking the only economically viable, environmentally friendly, totally scalable and truly sustainable replacement for petroleum we have on the table today? We have business models that will generate a volume of biodiesel that is 6x the total amount of petroleum refined on the planet annually. Again, you are echoing data from old 1st gen feedstock reports based on 50-100 gallons/acre/year from soy/canola. The way we make this work is for everyone to stop driving gasoline powered cars ASAP.

Any technological innovation that has a market will get funded by the private market. Discussing the science is great but it is the economics that determine whether it will be developed and survive in the marketplace. Further handicapping our defense by placing speculative financial burdens on it is an antiquated idea. Government survives on taxes and taxes are produced by profit. The men and women who serve in the military fighting and defending our country have been burdened enough by intellectual idealism. If a product cannot get funding with the amazing almost religious commitment to renewable energy we have globally it is a pipe dream! Every major corporation in the world is looking to go "green." The oil & energy industry has invested and will continue to invest in green technology because they want profit.

@ KGROSSMAN - I have a few comments. First, the 'proposed' 50% reduction would only kick in if congress cannot come up with a new budget bill. Who knows, they may shoot themselves in the foot again. Phamaciticals are based on low quanities, high prices and clean production environments. A full scale commercial pharma operation is like a piolet plant for fuel. Fuel is based on high volumes, low cost and relatively dirty plant conditions. Commercial development money would be there with a reliable demand. While the military is presently paying for some development (no research) they are not ready to sign a commercial contract. The investor looks for three things - technology, feedstock availability and market demand. Several technologies are there, feedstock will be there quickly if there is market demand. Market demand is what the military can supply and is heading for if Congress will allow them to do this. This is the issue described in the article.

This isn't even counting spills, blowouts, fires and other disasters-----mostly caused by negligence or willful safety violations cutting corners to increase profits. Now add the enormous cost of all this on public health. Now add all this cost and MORE to the economic damage of importing oil. Now add the human, political and economic costs of warfare to gain and secure oil supplies and logistics. Biofuels can be made from anything organic. Even sewage. We don't have to use fertilizer to make methane out of sewage. We have plenty of sewage and landfillls.........and we are not likely to run out. Ethanol can be made from sugarcane. Grass. It does not take much cultivation to get grass to grow. We do not have to use petroleum to harvest sugarcane----it has been used for hundreds of years before there even was such a thing as petroleum. And we do not need petroleum to run tractors, trucks or any other type of farm equipment. Diesel engines can run just fine on ethanol with the addition of a small amount of ignition enhancer. Scania has been running fleets of over 1,000 diesel buses in UK and Sweden for years, on ED95(ethanol diesel 95%). All of your babble about energy input/output and dependence on petroleum for anything is completely and totally false.

What is your second-gen feedstock? Does it require water, land, fertilizer? If so, it competes with food. Ammonium-nitrate fertilizer is made from natural gas (fossil fuel). What is the water footprint of your process? Conventional gasoline has a water footprint of 2.3 to 4.4 liters of water per liter of ethanol equivalent energy (per Argonne Nat'l Lab). This includes all the water used for enhanced oil recovery techniques and refining. In contrast, the biofuel crop with the smallest water footprint is sugar beet, and its irrigation and distillation consumes 1,388 liters of water per liter of produced sugar beet ethanol. Corn ethanol requires 2,570 liters per liter. Rapeseed biodiesel 14,200 liters per liter, and jatropha biodiesel 20,000. 2-in-5 people in the world don't have enough water for sanitation and 1-in-5 don't have enough to drink. "Second Generation" is a meaningless attempt to paper over the fact that there is no crop that does not compete with food. If you are doing waste-to-fuel instead of crop-based biofuels, I applaud you. But the simple fact is that you will never be able to generate sufficient quantity to displace fossil fuels.

@cliff-claven What color is the sky in your world? As the Cheers character, you seem to be somewhat confused about the world around you. We do not use any fossil fuels for biodiesel production - methanol production and biodiesel processors are powered with solar, wind and biodiesel gen sets (when necessary). Our vehicles, including harvester all run B100. Our energy return is about 3.6:1. Conventional diesel is a finite commodity and no one in the industry would quote energy return of petroleum diesel based on the remaining unconventional sources as the range is over an order of magnitude based on specific source. It might come as a surprise to learn that petroleum is sourced from plant material - primarily micro algae. We are already producing biodiesel at below $1/gallon - that will come down in the future as we scale up operations.

Your arguments are primarily based on 1st gen feedstock, though some seem to be confusing ethanol characteristics with advanced biodiesel. Also, none of you seem to be aware of advanced biodiesel additives. Our team has been working with the DoE, USDA, DoD, advanced labs and several universities for 7 years. We have orchards in 4 states and 2 foreign countries. We partnered with UOP and IFT and we lobby against 1st gen biodiesel feedstocks for most of the reasons cited above. That said, biodiesel from 2nd gen feedstock is the only economically viable, environmentally friendly, totally scalable and truly sustainable replacement for petroleum we have on the table today. At 850 gal/acre, we can replace 50% of all transportation fuel used by the US with less acreage than is currently being used for ethanol, soy and canola. 2nd gen feedstock does not displace food crops by def. A few details before I run out of chars... Today there are 7 commercial airlines that run biodiesel blends everyday. Not because it is more Green to do so, but because it is less expensive. Military jet engines, ground vehicles, ships, etc., are manufactured by the same companies that manufacture private sector engines. Each feedstock has different characteristics which requires each blend must be exhaustively tested - ISO standards. Every serious biodiesel producer has a mass-spec and lab. BTU per gallon of virgin biodiesel (no additives) is 119K BTU though we achieve 126K with additives. Petroleum sourced diesel typically has a rating of 129K. This is moot. Biodiesel with additives has a shelf life of 3 yrs and flows at -150C. Join the Migration - http://etcgreen.com - U.S. Migration

Biodiesel (fatty-acid methyl ester) is not a hydrocarbon and has lower energy density (less energy per gallon) and poorer flow and volatility characteristics than true diesel. Even so, its energy return on investment is less than 2:1 compared to more than 8:1 for conventional diesel. Making biodiesel into a true hydrocarbon "drop-in" substitute for diesel requires hydrotreating, which requires the expensive addition of pure hydrogen and further lowers its EROI. Argonne has reported that it takes 2.6 times a much fossil fuel to put a gallon of algae diesel in a service station pump as to put a gallon of fossil fuel diesel there, because of all the energy required to cultivate and process it. Keep reading.

The biofuel in discussion is principally biodiesel, which need not be produced from plant-based crops. The fact that it can be created from a host of other oils, fats and greases makes it particularly attractive as an alternative fuel, especially the military. Biodiesel, even from soybean oil, has a better energy balance than does petroleum-based diesel by almost 4:1 and yes, Cliff-Claven, that data is reported by the Argonne National Laboratory.

Those in Congress who voted to keep us dependent on fossil fuels should be tried for treason. DoD publicly acknowledges that fossil fuels are finite in supply and that their continued dependency is a national security threat. Our decades upon decades of subsidies to the fossil fuel industry have artifically lowered their price to the consumer. They pollute our air free of charge and poison everything downwind. There needs to be an immediate call for treason, led by DoD, or others to call those who voted for this and those that are funding it behind the curtain out.

Crop-based biofuels are an attempt at impossible perpetual motion. They require huge inputs of fossil fuel energy in the form of artificial fertilizer (made from natural gas) and diesel and gasoline and coal electricity required for cultivation, processing, and refining. If the resulting biomass is sun-dried and shoveled straight into a furnace for heat, the energy output is about break-even to the input. If, however, it is converted to liquid fuel, the energy out is far less than the energy in. Usable energy is lost in every process and conversion according to the non-negotiable second law of thermodynamics (entropy). This is the cold, hard fact that biofuels proponents ignore, and that no amount of government funding (i.e., deficit spending of our grandchildren's birthright) can alter. Creating a gallon of biofuel actually uses more fossil fuel than creating a gallon of conventional fuel (2.6 times more for algae biodiesel than conventional diesel according to Argonne National Laboratory). Biofuels are actually increasing our demand for fossil fuel. To paraphrase the Governor of Indiana, you can't trust the "PC Institute of Technology" or the "University of Hollywood" or "Encyclopedia Mainstream Media" on these issues. The truth is out there in the science journals if you want it.

One comment and Mr/Ms anonymous doesn't know his a** from a hole in the ground. If you can remember the news of the last week, Secretary of Defense, Leon Panetta, announced a general and long term repurposing of military assets to the Pacific and Asian theaters. This has been a policy a long time in the making. Reliable supply bases in this area are Hawaii and Australia, both a long, long way from the US and our strategic petroleum reserve and petroleum refiners. The Navy would like to shorten these supply lines, hence the push for biofuels which both Hawaii and Australia can supply. During their evaluation process at Wright Patterson AFB, it was discovered that jet engines could actually perform better on biofuels and that due to their lack of impurities could reduce maintenance as much as 10X. Biofuels development is primarily a matter of military readiness but it turns out that there are also tactical advantages and related cost savings advantages also. It is disgusting that the majority of our Congressmen and Senators that are supposed to sit on committees to look out for our national security have abdicated their responsibilities in favor of browning up to the oil industry.

The US military spends staggering amounts of money on diesel & jet fuels. By far, the largest contributor to this cost is transporting the fuel to where it is needed. Shipping a gallon of diesel fuel to a front line base overseas can easily add $50 dollars or more. As for using biostocks for jet fuels, this also presents potential issues. The Army, Navy, Marines and Air Force spend millions of dollars qualifying their aircraft turbine engines for operation on specific common fuel types. It would literally cost hundreds of millions of dollars to re-qualify all of the turbine engines in those inventories for use with biofuels. To ensure a continued supply of fuels for the US military during wartime we already have something called the strategic petroleum reserve. And in an emergency, the US government would also divert any domestic production. So biofuels for military use does not make sense, except as political posturing.
