 With the market for cellulosic ethanol in the United States projected to continue growing in the coming years, the outlook for this industry is good.The US Federal government is actively promoting the development of ethanol from cellulosic feedstocks as an alternative to conventional petroleum transportation fuels.For example, programs sponsored by U.S. Department of Energy (DOE) include research to develop better cellulose hydrolysis enzymes and ethanol-fermenting organisms, to engineering studies of potential processes, to co-funding initial ethanol from cellulosic biomass demonstration and production facilities.
