Coskata announced today that they are building a demonstration-sized (40,000 gallon per year) cellulosic ethanol plant. This is significant because it could represent the first scale-up of a syngas-fermentation (SF) pilot technology in the world.
The other possible scale-up of this advanced technology is the BRI process that is a party to the ALICO project - a DOE EPAact grant winner of last year. That project is still awaiting licensing resolution among the parties that submitted the original proposal.
Ethanol is almost always seen as a process involving the fermentation of sugars into alcohol. Most of the debates about ethanol has to do with what feedstocks are going to be used and what process to break down the feedstock structure to isolate the sugars. The yield comes only from the sugar in the feedstock. Food vs. fuel, Energy Return on Investment (EROI), water usage, biofuel yield - these are all very real issues that will impact what, where, and how facilities will be located and financed.
Syngas-fermentation offers an alternative. Instead of biologically breaking down the feedstock using enzymes, the feedstock is gasified into component molecules of carbon monoxide and hydrogen. These become the building blocks for reformulation as higher alcohols. Some technologies, like Range Fuels', use inorganic catalysts to effect the reformulation. SF, on the other hand, relies on microorganisms in controlled bioreactors to eat up the syngas and produce ethanol and water.
It is a very attractive alternative because it is omnivorous (any blended biomass will do including unrecyclable urban waste and fossil derivatives like tires, auto fluff, petcoke, and plastics). The yield is high because the non-sugar content of the feedstock can be utilized for its molecules. The higher the content of carbon in the feedstock, the higher the yield of ethanol gallons per ton. It requires very little water (roughly 1 gallon per gallon of biofuel) and most of the energy for gasification comes from the feedstock itself.
Below is the complete press release that was posted today.
Coskata Inc. Chooses Madison, Pa. for Commercial Demonstration Facility to Produce Next-Generation Ethanol
Alter Nrg, Westinghouse Plasma to support 40,000 gallon cellulosic ethanol plant
Madison, Pa. – April 25, 2008 – Coskata Inc., a leading developer of next-generation biofuels, said today it will produce 40,000 gallons of cellulosic ethanol a year at a commercial demonstration plant near Pittsburgh.
The $25 million project will be located at the Westinghouse Plasma Center, the current site of a pilot-plant gasifier owned and operated by Westinghouse Plasma Corporation (WPC), a wholly owned subsidiary of Alter Nrg Corp.
“Coskata has been eager to reach this milestone, because it will be a significant demonstration before building our first commercial plant that we can produce ethanol from non-food based sources for less than $1 a gallon,” said Bill Roe, president and CEO of Coskata. “This facility is being built with some of the leading gasification technology, supplied by Alter NRG, and in one of the most progressive states for next generation ethanol."
The plant, located about 30 miles southeast of Pittsburgh, is expected to begin delivering ethanol in early 2009 utilizing a variety of input materials, including woody biomass as well as agricultural and industrial wastes. General Motors, a strategic partner and investor in Coskata, will use the next generation ethanol for testing in flex-fuel vehicles at its Milford, Mich., Proving Grounds.
“We are delighted Coskata has chosen the State of Pennsylvania as the first location for production of their next generation ethanol,” said Pennsylvania Governor Ed Rendell. “Coskata’s cutting edge facility will strengthen Pennsylvania’s already first class reputation as a leader in producing and delivering alternative fuels and will bring us one step closer to further reducing our dependence on foreign oil.”
Coskata announced in February that it will commission a full-scale, 50 million – 100 million gallon-per-year commercial plant by the year 2011. This facility is being planned in parallel with the construction of the Madison demonstration facility and is expected to break ground this year.
“The Coskata syngas to ethanol plant, using Westinghouse Plasma Corporation’s gasifier will make for a world-class demonstration,” said Mark Montemurro, President and Chief Executive Officer of Alter Nrg. “We view Coskata’s highly efficient process as a perfect complement to our environmentally responsible gasification technology.”
Coskata leverages proprietary microorganisms and efficient bioreactor designs in a unique three-step conversion process that can turn virtually any carbon-based feedstock into ethanol, from anywhere in the world.
Coskata’s process for next-generation ethanol is environmentally superior, reducing carbon dioxide emissions by as much as 84% compared to conventional gasoline; and has the ability to generate up to 7.7 times as much energy as is required to produce the ethanol, as verified by Argonne National Labs in a well-to-wheel analysis. Additionally, Coskata’s process uses less than a gallon of process water to make a gallon of ethanol, compared with three gallons or more required by other processes.
Coskata is a biology-based renewable energy company that is commercializing technology to produce biofuels from a wide variety of feedstocks. Using proprietary microorganisms and transformative bioreactor designs, the company will produce ethanol for under $1 per gallon almost anywhere in the world, from a wide variety of feedstocks. Coskata has compiled a strong IP portfolio of patents, trade secrets and know-how and assembled a first-class team for the development and commercialization of its compelling syngas-to-ethanol process technology.
