Clean Energy, New Jobs

New jobs for many people in alternative energy,
Revitalizing communities by cooperative strategy,
Reaching out for avenues in clean power production,
Will help rural communities with unemployment reduction,
All across America shines bright hope for all,
A new way of life is promised and will help us recall,
We're people who are used to solving problems that arise,
We're not afraid of changes, that you may surmise,
We dig our heels into the ground and start where we've been halted,
To move into renewables for they are what we've wanted,
Oil, coal and gas are here to stay awhile as power friends,
But not forever, keep in mind, we need some fresh new blends.

Wayne,
The plant will use waste woodchips from timber harvesting operations in northern New Hampshire. It is unclear if the fuel will come from anywhere else.
Sorry I didn't make that more clear before. It's now changed. Thanks!

An interesting article but what are they actually using for fuel? Wood ..?

Jim, you are 100% right. It is not clean energy if wood chips are used but then again, it would not be considered fossil energy, though the amounts of CO2 released would be on par with coal. Probably the sulfur content might be lower with wood than with some of the coals but burning wood does produce harmful fumes as is evident by the harm done to women and children in poor places such as Africa and India.

If they are using wood chips, then this is not "clean" energy though it is renewable.

I would speculate that the CO2 released per kwh would be roughly on par with coal and wood.

Gentlemen,

According to Laidlaw Energy, "the emissions from the facility will be maintained at an unprecedented low level through the use of highly advanced, second generation emissions controls that are expected to enable the plant to qualify for the renewable energy programs of various states in the Northeast and allow for the sale of Renewable Energy Credits (RECs)."

Therefore, while there will indeed be emissions, I suspect it will be cleaner than coal-fired power plants, many of which do not implement such strict controls.

Also, Laidlaw is looking to partner with another company to occupy the rest of the site so that the occupant could use some of the electricity and waste heat from the plant. Laidlaw says they are considering many types of partnerships, one of which is for a biofuel application.

Excuse COMMENT HOG STATUS OF CRAZY PHIL....however, sounds like a great location for "spent heat" to enable a great deal of "gardens", nursuries, flower growth, WINTER "WONDERLANDS " !!! Somebody just might figure out a way to make ON-SITE-FERTILIZER OR CHARCOAL OR UPSCALE "BRICQUETS" FOR COOKERS.....ETC. Was it Henry Ford...looking for safety glass...who said...GIVE ME 5 ENGINEERS WHO DO NOT KNOW....IT CANNOT BE DONE !!!! History shows Henry got his Glass !!!

NOTE: At IP Georgetown SC in ca. 1975 one of the Chemists ran a test using ground-up garbage in one of the boilers....he said it was very close to the same BTU output as wood chips...just a little more particulate matter residuals in the boiler....MARRY UP THE OLD PAPERMILL WITH HIGH TEC TRASH RECOVERY a la St. Lewis Mo......you might just really have something that would not only meet the spoken goals....maybe double or triple them...maybe <*///><

Help me please...are we saying...there is no technology that can help "economically" reduce-its-carbon-footprint : either now or in the future ????? This power plant will operate with no scrubbers, no filters, no reclaimers, no recovery devices whatever ????>? Solar and/or Wind CANNOT offset the "cost" of high-tec CARBON CAPTURE...having spent a few electrical years at IP-Georgetown SC....the entire mill had at least 50 great spots for solar or wind installations that could "pay" for new tecnology....if such exists ???most paper mills...not all have great water resourses, perfect forwww.pyronsolar.comtechnology. <*///><

I have a few quick comments:
First, while energy from biomass may be renewable, it's not as clean as some other sources. The use of forests for producing timber for long-lived buildings effectively sequesters CO2, it's better than a CO2 neutral process. Creating more markets for biomass typically changes how a forest is managed. In the first biomass boom in Maine, we saw indiscriminate clearcutting with all of it going to hog fuel (the colloquial term for biomass). These are also typically rather low efficiency ways to use biomass. In fact, using pellets in a stove in your home is a much more effective use of the resource.

The comment on burning trash misses the mark. You might write a story about the revitalization of Old Town, ME, where the paper mill has been replaced by a "biomass boiler" aka trash incinerator. It's a dirty business, with the focus on burning trash from Mass, not on producing clean renewable energy.

Question: Where did our soil come from and where is it going to come from in the future, if we strip every ounce of biomass from every field and forest to burn it? If we had an efficient means of putting the ash back on the land, this might not be a big problem, but I can't see that happening. I'm not just trying to be a smart-ass, this is a real question.

There is no economic point for using straight timber for fuel as it has other feasible uses and is too costly as well. Thus, I don´t believe it could contribute to deforestation, at least in the case mentioned.

I hope that the energy will be utilized in a district heating scheme as well, otherwise it would be a severe waste of resources. Combined heat and power is the most cost efficient of all since an enormous ammount of heat is being produced anyways.

I want to add just a few comments, though I have more.. :)

Biomass, in whatever form is 100% renewable and CO2 NEUTRAL - this means that CO2 was harvested (in the form of wood) from the natural ecosystem and then returned to the atmosphere as a gas which is then taken up again by more biological organisms later.

Biomass can be grown as a crop, especially in the form of solix - a member of the willow tree/bush family. Solix grow incredibly fast and can be harvested yearly.

Solix are also especially apt at cleaning the soil from pollutants, that is they take them up in their roots and send along up into the plant. The crop is harvested, processed into pellets or chips and then used as fuel. When the biomass is burned, the filters in the plant´s emissions system can absorb the pollutants,and then can be deoposited in a sealed landfill.

For all the high-tech talk of biomass, it is still just burning wood, and lots of it, for inefficient energy production. Pyrolysis, anaerobic digestion for methane, or cellulosic, though admittedly more high-tech [more jobs?], would surely get better energy returns from wood waste. I would also suggest that "wood waste" is not necessarily "waste" if it decomposes and replenishes forest soils.

Gentlemen,

I think you may be overlooking the main advantage of wood vs. coal-based power generation. With wood, the CO2 generated is absorbed again by a new crop of trees. With coal you are releasing copious amounts of CO2 that has been stored for millions of years. I can't speak to the relase of any other particulate matter in wood but I'm inclined to believe it is significantly cleaner than coal.

My concern with wood-based power is that I see no mechanism for preventing wood-based power from accelerating deforestation. The US has been remarkably willing to cut down trees for paper, furniture, housing and many other products. How much more willing will we be when wood also produces our electricity? The LaidLaw plant will use "wood chips", presumably from forestry waste. Who will ensure that use remains limited to this existing waste, particulary when the idea becomes more popular and firms compete for a dwindling supply of surplus waste?

Mrs. Hutter,
I am no Chemist but I am a teacher, "wood produces more polutants than coal"
A. numerically the count of polutants
B. by weight
C. by "polutant strength"
D. percentage of origional mass converted to polutants

I am certain, clean vs. dirty coal would have very different values...I would be interested in these questionsmather_2001jr@yahoo.com THANKS

Burning wood releases more pollutants than coal. Scrubbers remove the Sulphur and Nitrogen pollutants by dissolving them into water. The resulting water is then polluted and must be dealt with. My husband is an engineering manager that works for a company that installs industrial scrubbers. The burning of any fossil fuels still creates real environmental hazards --the only thing that really changes is the state they are in (i.e. gas, solid or liquid form). New technologies will have to be developed in order for the burning of anything to be truly "clean".

The renewed use of the paper mill plant in New Hampshire is a reasonable SHORT term use of the facility and will need to be converted again as technologies are developed and legislations change to reflect tighter and tighter standards.

GENTLEMAN AND LADIES:

Soil comments, Mr. S. McMeekin....Penn State Uni has be working for years on soil reclamation particularly in strip mineing. I am sure they have expertese in this area. Soil Science College, State College, PA.
Old Town ME. "incinerator"...I hope they took some ques from the St. Lewis MO. process....over 30 years "developed" (-ing), A few years back : 100 thousand USD's in coins recovered and 800 thousand USD's electricity sold back to the CITY on an annual basis...JUST FROM TRASH ! The technology is out there...I have forgotten the name of the book and the man...help me...read it as a child: it was the story of the brilliant man who guided with lots of help AMERICA'S gearing up to fight WWII MODERN ARMS AND FREE MEN I think was the title...got to be 50 years ago. A WE ARE AT WAR AND B WE WISH TO REMAIN FREE AND C WE DESPERATELY NEED A PLAN w/ DETERMINATION ! RESPECTFULLYmather_2001jr@yahoo.com

This is interesting. Some say biomass is worse than coal some say its the same, and some say its less. I thought engineers dealt with scientific evidence. It would be nice to get the facts straight. If your not sure, say so.
As one person said here, if we're burning we're polluting.
