The use of biomass should be determined by the market (not politicians, bureaucrats or entrenched industry interests armed with dubious energy efficiency assumptions). The largest and most economic potential use of biomass is the cogeneration of both electricity and heat, with minimal fuel treatment (i.e., no pelletization). Unfortunately, the most recent issue of Power Engineering states that, even though cogeneration fueled by biomass wastes is economic without subsidies, it is blocked by government and utility monopolies.

Thank you for that informative article. Bulk wood pellet usage is the most economic and convenient way of using biomass. There are several companies starting to offer bulk delivery as well as pellet heaiting systems as convenient as oil boilers.
For example www.mesys.net offers bulk delivery and very sophisticated heating systems produced in the US under license from an Austrian firm www.okofen-usa.com

Pelletization adds significantly to the costs of burning biomass fuel. It only makes sense for small burners and long distance trucking of the fuel. But this makes little sense in itself. The biomass industry is forced to focus on a market where it doesn't belong - competition with small gas burners. The US must open up the power markets from utility monopolization so the fuel can be used most economically.

I always cringe when I see statements like, "A ton of pellets gives you the same amount of heat ... when you factor in the efficiency gains from space heating with a pellet stove."

I'm game, how do they compare if I burn them in my modified heating oil system?

Space heating is well and good, but this is an invalid comparison. One has to presume the numbers are not as good for the wood pellets when using a conventional system.

Biomass is renewable, creaates long term jobs, and is pleasant to use. We love to sit beside a log fire, knowing we are using a clean, inexpensive product, which is needed and does no harm.John Olsen Cree Industries

I feel that pure combustion totally misuses the best qualities of Biomass.
Soil carbon sequestration is the main one, and sheer economics the other as exemplified by this TLUD gasifier below

Chip Energy Biomass Furnace
500 lb chips / day = 180,000 BTU / hr + 85lb Biochar / day
The price of chips and / or pellets would be more than off set by bagged char sales of $50 / day
500lb wood pellets cost = $40
500lb Hogfuel / wood chips = $10
In other words; Free Heat

The Ag Soil Carbon standard is in the second phase of review by the ARC branch at USDA.
After initial review, approval is expected in the next month. Contact Gary Delong . www.novecta.com 515-334-7305 office

Erich,

I don't believe any one technology "totally" uses/misuses a resource.

There are so many factors that the 'best' solutions vary from situation to situation. Often, the best solutions are hybrids. Solar heat, natural gas, and biomass/fuel have yet to 'marry'/evolve into better systems. Even coal can be used, in moderation.

It is a real stretch to imply that burning wood is carbon neutral. If you wait up to 70 years for the trees to grow back they may sequester the carbon released by by burning. However, in the short term, about the same amount of carbon is relaeased by burning wood as by burning coal.

I like my woodgas campstove. I like the idea of combined heat/power with biomass. I think as it becomes more popular , big oil , gas and electric will have to reduce their prices to put biogas down. There is no peak oil or gas, just regulated production, and greed. Oil and coal and nuclear are all DIRTY!
Thats where biofuels must stand, it's cleaner and safer. And for that end I will stand with renewables. At recovery.gov they gave 1.4 Billion dollars to a company to decomission and clean up a nuclear plant in South Carolina. The 16,000 barrels of nuclear waste will be shipped all over the country.
They say Tritium is in the ground water. So what then? peace

It isn't even necessary to burn bio-mass to get heat. If you get your carbon/nitrogen mix right, you can coil PEX in a pile and heat water while you are making humus.

You can generate mushrooms and squash babies, even in the winter. We haven't needed to be this resourceful in previous times, but necessity mothers all sorts of new tricks and some re-discovered old ones.

Ellen de Generes recently hosted a show where a young actress had spent time in an Ecovillage in Oregon, where she learned to pee in a bucket so that nitrogen, diluted 10 to 1 for some plants, could be put where it is most needed rather than underground.

And it's not just the nitrogen. We are supposedly approaching Peak Phosphorus, and the Chinese are allegedly on a world hunt for places to mine it. With so many people, I'm a bit at a loss about this.

In rainforests, we have plenty of nitrogen and carbon, by limbing up against fire in the dry season. Coppicing is an old village practice that we probably don't do enough presently.

In the Northwest, salmon still bring nitrogen and phosphorus, along with other elements, back to us from the ocean, where we have flushed it down in greater amounts than back when we had far more plentiful salmon.

And the word permaculture is getting out on the airwaves, even if academic experts have never heard it. I heard a caller ask about in yesterday on a public-radio show about Haiti. The response indicated to me the academic preferred to have Monsanto seeds taken into Haiti. Others of us will want organic seeds from elsewhere in. We will see what Haitians decide.

My son sends word that a permaculture expert is coming to MIT, and they are searching for a room big enough to host those interested.

Change happens anyway, even while those who promise it appoint stonewallers against it to high offices and big salaries.

One of my exercise students is converting to pellets. She's excited about it.

Dear William-bradley & RT-55,

Thermal conversion "burns" the Gas & oils, not the wood, the cell structure is conserved as elemental carbon, every 1 ton of Biomass yields 1/3 ton Charcoal for soil Sequestration (= to 1 Ton CO2e) + Bio-Gas & Bio-oil fuels = to 1MWh exported electricity, so is a virtuous, carbon negative, energy cycle.

Low cost Biomass cook stoves that produce char and no respiratory disease emissions. At Scale, replacing "Three Stone" stoves, the health benefits would equal eradication of Malaria
http://biocharfund.org/

These stoves burn 60% less fuel / meal; http://worldstove.com/

Haiti:
WorldStove is on the ground with a major biochar stove relief project. Donate: 501c3 account for WorldStove's Haitian Stove Project at International Lifeline fund: International Lifeline Fund

WorldStove got this effort moving on Jan 14, just 2 days after the quake. You can follow them on Twitter: WorldStove (WorldStove) on Twitter; http://twitter.com/WorldStove


All political persuasions agree, building soil carbon is GOOD.
To Hard bitten Farmers, wary of carbon regulations that only increase their costs, Building soil carbon is a savory bone, to do well while doing good.

Biochar provides the tool powerful enough to cover Farming's carbon foot print while lowering cost simultaneously.

As I read the agronomic history of civilization, only the Kayopo Amazon Indians and the Egyptians
(Nile floods, which they now have forsaken) have maintained fertility for the long haul.

We are also in De-nile about our own soil carbon loss over time due to technical mitigations like NPK and the green revolution.

The true "Gold" standard of sustainability is soil carbon, measurable soon by earth sensing satellites, available for all to see their good (or bad) works.

Agriculture allowed our cultural accent and Agriculture will now prevent our descent.

Carbon to the Soil, the only ubiquitous and economic place to put it.
Cheers,

There are composting toilets for using your "waste" for composting and conditioning "pee" for garden use. Today, they cost less than conventional septic systems and do not compromise your well water.

Biomass is only any stretch of efficiency if one does not consider what biomass would naturally be for if it were not burned. Billions of years of soil development has given this country great topsoil, which we have considerably wasted thru intensive farming without worry because of petro plant foods, now diminishing also. Biomass is for soil building according to natural systems. Burning everything that can burn is not efficiency, but insanity. A stop gap waypoint while truly sustainable means from solar energy are developed.

Phil,

Plants are a form of solar energy. Direct use of solar heat for distributed energy is inefficient due to conversion rates and lack of storage - same with PV.

There are lots of issues with solar and biomass but they can be solved over time. Not all biomass has to be burned.

Personally, I like Mary's suggestion of tapping the heat from a compost pile. However, that reduces the optimal temperature of the pile affecting the final product. It may be better to pump heat into the pile, in some northern locations.

Aerobic and anaerobic digestion produces useful gases as well as secondary products. Often the 'fuel' for these processes is manure, as opposed to wood (biomass means many things).

The author of this article has a specific interest in wood pellets. You get what you pay for.

Geo thermal production of electricity is about 10% more efficient than bio-mass. meaning it produces at nearly 99% efficiency, and the by-product is steam which has a half life of less than one 1/2 hour. Plus it's fall out is water.
Why has the alternative energy community spent well over 90% of it's ?energy? on Solar, Wind, Bio-Mass et al and even ???CLEAN??? Coal?
Isn't Clean Coal an oxymoron up at the level of "Army Intelligence?" We have a heat source, the Earth, that will last, according to scientists, another 4.5 billion years. It has heat at every level of the planet, i.e.; Yellowstone National Park, Wyoming, the volcanoes of the Island of Hawaii, the volcanoes of Southwest Alaska, plus any place you drill down 12,000 feet.

Geothermal for heating and cooling for residential and commercial building use is available six feet under the surface. It's commercial and also does some or all of hot water loads. It moves heat rather than creating heat. Zero emissions if using grid or on site elec power.

To a question posed above, the answer is yes. I use the sawdust method I first encountered at Crater Lake. You would perhaps be astonished at the number of advanced adopters who do this in the west coast town where I live.

We are constantly reminded that the big quake is coming.

I am not sure the powers that be (PTB's) understand the behavior changes our knowledge of seismic risk encourages, but some of us will be ready for broken sewer and water lines.
