Have folks seen this one?
Anyone know what this "thermal conversion process" is?
Range Says Will Make Wood Cellulosic Fuel in 2008
US: November 8, 2007
NEW YORK - Private US company Range Fuels broke ground on Tuesday on
a biorefinery that will be the first plant to make commercial levels
of cellulosic ethanol starting next year, its CEO said.
Range Fuels is one of six companies that will receive a total of
about US$385 million in grants from the US Department of Energy for
making cellulosic fuel.
The biorefinery is being built in Georgia, home to large swaths of
private forest land. It will initially make 20 million gallons per
year of ethanol from sawdust, pine trees and wood bits left over from
cutting down lumber. It is slated to eventually grow to 100 million
gpy of production.
Mitch Manditch, the CEO of Range Fuels, said ideally the plant would
use mostly wood waste as a feedstock.
"That's our preference, just to keep costs down, because no one else
wants that wood," he said in a telephone interview.
Making cellulosic ethanol currently costs about twice as much as US
traditional ethanol made mostly from corn. But industry experts
estimate that costs will fall enough to let cellulosic become a
commercial fuel in several years, one that will emit less greenhouse
gases and won't use up prime farm land like corn-based ethanol does.
ETHANOL GLUT
US ethanol refining capacity has shot up 30 percent since Jan 1. to 7
billion gpy as the Bush administration offers companies incentives to
make a domestic source of fuel. Record oil prices near US$100 a
barrel and concerns about greenhouse gases have also fueled a rise to
cellulosic ethanol.
But the boom has helped lead to low ethanol prices and high corn
prices that have crushed margins for making the fuel. Since wood
waste is far cheaper as a feedstock, Range hopes the plant would
eventually be more profitable than corn biorefineries.
Cellulosic ethanol is made from breaking down the woody bits of
plants. A whole new range of crops that grow on marginal lands, such
as switchgrass, can be used.
When the final Range plant is completed, it will cost several hundred
million dollars, Manditch said. The plant will receive up to US$76
million from the DOE.
Range is funded in part by venture capitalists including Vinod
Khosla, a top Silicon Valley investor who is also helping to fund US
biofuels company Cilion and other alternative energy companies.
Manditch said Range will use a thermal conversion process to make the
fuel, unlike most other companies that are planning to make it with
enzymes to break down the tough feedstocks. He said Range Fuel
ethanol will emit about 75 to 80 percent less greenhouse gas than
ethanol made from corn. Part of the emissions are saved because the
plant will not ferment the feedstock, a process used in corn ethanol, he said.
The thermal process can also break down other feedstocks, such as
switchgrass, Manditch said.
