BETO offers a range of materials providing information on BETO activities, research, publications, tools, multimedia, and terminology.

Information on bioenergy careers and workforce development, plus STEM and other educational resources.

Biopower technologies convert renewable biomass fuels into heat and electricity using processes similar to those used with fossil fuels.

BETO’s Advanced Algal Systems Program focuses on improving productivity of algal biomass and enhancing cultivation and harvesting efficiency.

The Alternative Fuels and Feedstocks Office (AFFO), formerly known as the Bioenergy Technologies Office works to 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. develop industrially relevant technologies to enable domestically produced biofuels and bioproducts...
