Vinod Khosla builds his first cellulosic ethanol plant in Georgia
Venture capitalist Vinod Khosla, who's been a major player in the race towards efficient cellulosic ethanol production (earlier post), has announced his biofuel firm Range Fuels will build its first plant in Georgia.
Over at BioStockBlog, C. Scott Miller explains the plant's main biomass feedstock will be wood waste from the state’s millions of hectares of indigenous Georgia Pine. Range Fuel's bioconversion technology allows for the utilisation of otherwise useless products such as wood chips, agricultural wastes, grasses, and cornstalks as well as hog manure, municipal garbage, sawdust and paper pulp.
The company's ethanol production process is two-fold: a thermochemical gasification process breaks down the lignocellulosic biomass into so-called syngas; in a second step, the gas is transformed into ethanol. This thermochemical conversion route is entirely different from the biochemical option that is currently being researched and which consists of using specially designed enzymes to break down the cellulose.
Like most biomass-to-liquids concepts (earlier post, and here), Range Fuel's plants are modular:
biomass :: bioenergy :: biofuels :: energy :: sustainability :: wood :: waste :: cellulose :: ethanol :: biomass-to-liquids :: U.S. ::
This means the plant can be decentralised and located near the biomass resource, where the bulky feedstock will be transformed into an energy dense liquid. This liquid can then be transported to more centrally located refining facilities where it is turned into the final product. The modular concept means that transport costs and fuel consumption are kept low and that the system can be scaled-up as biomass availability increases: just add another module.
C. Scott Miller sketches the context of Khosla's initiative, and shows that woody biomass holds a vast potential in the U.S. - a far bigger potential than corn stover:
Range Fuels estimates that this first plant – combined with others to follow – will have the capacity to produce over 1 billion gallons of ethanol per year. The first plant will create over 70 new jobs for the area.

The high energy potential of wood cellulose, the ready available of cheap waste, and the search for a renaissance of forestry-based industries makes the announcement a welcome one to the "nation's woodpile" in the southeastern states.Announcing the initiative, Khosla himself speaks of a 'war on oil': “the production of cellulosic ethanol represents not only a step toward true energy diversity for the country, but a very cost-effective alternative to fossil fuels. It is advanced weaponry in the war on oil.” Earlier he has indicated he could see cellulosic fuel prices sinking to US$1 per gallon within 10 years.
