– Two US companies have announce new approaches

Two US companies have announced an innovative, cogeneration-style approach to reducing the amount of energy required to produce ethanol.

Headwaters Incorporated has signed an agreement to build an ethanol plant next to Great River Energy’s Coal Creek Station power plant near Underwood, North Dakota, US. The proposed facility would use the waste heat from the coal-fired power plant in place of a boiler, thus saving energy while reducing emissions from the ethanol plant, reports the US Department of Energy. The plant will be able to produce 200 million litres of ethanol per year, and the two companies plan to begin construction in the autumn and start producing ethanol in the autumn of 2006.
