The DOE Office of Energy Efficiency and Renewable Energy, Advanced Manufacturing Office (AMO) (http://www1.eere.energy.gov/manufacturing/ ) seeks transformational manufacturing and materials technologies that reduce primary energy use in manufacturing by 50% without sacrificing product quality, production throughput or life cycle cost. The technology should provide a pathway to a doubling of energy productivity in a U.S. industry through innovative manufacturing and novel materials concepts, including (a) manufacturing process and (b) advanced materials technologies.Manufacturing technologies of interest include innovations in: reactions and separations such as high performance membranes and catalysts; alternatives to conventional high-temperature processing technologies; and waste heat recovery and recycling that reduce energy use?50%
