The US Environmental Protection Agency (EPA) has given fuel registration to Madison-based Virent Inc’s BioForm gasoline, which allows the fuel to be used in on-highway motor vehicles. During testing, the plant sugar-based fuel, which contains up to a 45 percent blend with conventional gasoline, demonstrated that the emissions from the biofuel were well below current standards. The biofuel, made at Virent’s demonstration plant in Madison, WI, is high-octane and is compatible with existing refining and distribution infrastructure networks. Currently, the biofuel has been used by Shell in road tests and by Ferrari cars in Formula One Grand Prix. For more information click here and here
