plant in Nevada will use a geothermal energy source. The plant, to be built by Infinifuel (cool name, that) will build the biodiesel plant as part of facility that generates 5 MW of electricity from two production geothermal wells and seven power production units, while the 220 degree steam will be used in the production of biodiesel. All of this geothermal power will be able to produce five million gallons of biodiesel a year, made from oilseed and/or algae (Infinifuel is in discussions with the University of Nevada Reno Agricultural Extension and the Desert Research Institute to find the best feedstock). This will be the first geothermal power plant in Nevada, Infinifuel says.
