A 1.4 million gallon demonstration-scale plant will use waste biomass to make biofuel. (http://www.technologyreview.com/Energy/20828/)

A biorefinery built to produce 1.4 million gallons of ethanol a year from cellulosic biomass will open tomorrow in Jennings, LA. Built by Verenium, based in Cambridge, MA, the plant will make ethanol from agricultural waste left over from processing sugarcane.

The new Verenium plant is the first demonstration-scale cellulosic ethanol plant in the United States. It will be used to try out variations on the company's technology and is designed to run continuously. Verenium wants to demonstrate that it can create ethanol for $2 a gallon, which it hopes will make the fuel competitive with other types of ethanol and gasoline. Next year, the company plans to begin construction on commercial plants that will each produce about 20 to 30 million gallons of ethanol a year.

Until now, technology for converting nonfood feedstocks into ethanol has been limited to the lab and to small-scale pilot plants that can produce thousands of gallons of ethanol a year. Since these don't operate continuously, they don't give an accurate idea of how much it will ultimately cost to produce cellulosic ethanol in a commercial-scale facility.

Almost all ethanol biofuel in the United States is currently made from corn kernels. But the need for cellulosic feedstocks of ethanol has been underscored recently as food prices worldwide have risen sharply, in part because of the use of corn as a source of biofuels. At the same time, the rising cost of corn and gas have begun to make cellulosic ethanol more commercially attractive, says Wallace Tyner, a professor of agricultural economics at Purdue University. A new Renewable Fuels Standard, part of an energy bill that became law late last year, mandates the use of 100 million gallons of cellulosic biofuels by 2010, and 16 billion by 2022.

So far, however, there are no commercial-scale cellulosic ethanol plants in operation in the United States, although a number of facilities are scheduled to start production in the next few years. The Department of Energy is currently funding more than a dozen companies that will be building demonstration- and commercial-scale plants. One of these, Range Fuels, based in Broomfield, CO, plans to open a commercial-scale plant next year. It will have the capacity to produce 20 million gallons of ethanol and methanol a year… http://www.technologyreview.com/Energy/20828/

Woot! I'm glad to see cellulosic Ethanol finally becoming a reality.

Cellulosic biomass > sugar > corn.

can I get them to mow my lawn in exchange for taking the grass clippings to use as 'biomass'

I agree, this is a welcome sign.

Interesting, I was driving home the other day thinking the same thing... Collect peoples clippings and the clippings from the highway cutters and you have a great resource!

I am so glad to see a switch (be it small and only one) away from corn... corn is a TERRIBLE idea on so many levels.... (IMO)

You can't have my grass clippings! They are a major component of my compost! :p

Yeah.. I use mine for composting too... but my composter is completely full! I have been shoving grass clippings everywhere under shrubs between mine and the neighbors fence, where ever I want to stifle weeks... but I am running out of room! LOL Damn grass just grows to darn fast!

Good news. Now, they may be able to make it cheap, but is it still an incredibly water intensive process? Any downsides? Is there enough biomass to put a dent in current consumption (assuming we had the factory capacity)?

Biomass is one thing this planet has no shortage of. From forest underbrush to pine needle droppings to corn stalks to algae in the waterways to weeds everywhere... plenty to go around and it is 100% self-renewable when left alone.

It sounded like their feedstock was specific to two species--sugar cane and a close relative--and that current crop land was being used in its production. Benefits of the process versus say, sugar cane ethanol production probably should be evaluated in large part on a gallons per acre comparison. Comparison to corn ethanol production is likely to be an apples to oranges comparison since corn grows well in many places sugar cane doesn't.

To me the article didn't sound like this is a generic biomass cellulosic ethanol process (which is probably an unobtainable ideal anyway) so your compost pile should still be safe:p. At least it sounds like a positive development for ethanol production in sugar cane growing regions. We can hope that the process adapts well to other feedstocks.

fermented using genetically modified E. coli.

...that is perhaps just a little disturbing...I hope it doesn't get loose...

Maybe we could turn in our clippings and get credit for X amount of fuel at the nearest ethanol station?

I'm all for ethanol as a viable alternative energy if we could make it affordable and practical. (And renewable and reasonably clean...)

And that they keep ethanol out of my GASOLINE-powered car.
