Coskata to build demonstration-scale facility in Illinois; to produce $1 per gallon cellolosic ethanol

April 25, 2008

In Illinois, Coskata announced that they will build their 40,000 gallon demonstration plant for cellulosic ethanol in Madison. The company’s process heats raw materials to 17800 degrees fahrenheit, then releases the material into a bioreactor where microbes convert the gas into ethanol, with a yield of 100 gallons per ton of feedstock at a cost of less than $1 per gallon.

The CEO of Coskata recently detailed how the company can create fuel for less than $1 per gallon using its combined thermochemical and microbe-based approach to cellulosic ethanol production. William Roe said that the company’s process can use multiple “true waste” feedstocks such as wood chips, weeds, human waste, used tires, or carbon monoxide.

Roe said that the company could co-locate with steel mills to convert CO into as much as 50 billion gallons of gasoline per year. He added that the company does not expect to make fuel, except for a 40,000 gallon demonstration facility, but expects to license its process to large-scale producers.
