The Alternative Fuels and Feedstocks Office (AFFO), which brings together legacy efforts under the former Bioenergy Technologies Office and Hydrogen and Fuel Cell Technologies Office, provides funding for bioenergy industry and hydrogen and full cell technologies lab-led consortia.

The U.S. Department of Energy’s (DOE) Alternative Fuel and Feedstocks Office (AFFO), enables research, development, and demonstration (RD&D) to accelerate technology commercialization for the production, storage, delivery and use of alternative fuels, fertilizers, chemicals, and feedstocks to enhance the security and reliability of energy networks and lower energy costs for Americans.

The U.S. Department of Energy’s (DOE) Alternative Fuels and Feedstocks Office (AFFO) today announced up to $58 million in funding to advance novel, high-impact chemical technologies that use domestically sourced alternative and waste feedstocks. Projects funded through this initiative will advance new methods of chemical production that maximize the use of America’s vast biomass and waste resources.
