On January 8, 2019, the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) announced the extension of the deadline for algae, biomass, and waste feedstock research request for information (RFI). EERE’s Bioenergy Technologies Office (BETO) is requesting information on research opportunities associated with alternative feedstocks that can be used in the production of biopower, bioproducts, and biofuel. Particularly of interest to DOE are the following topic areas: Outdoor Algae Research; Biomass Characteristics and Feedstock Performance; and Renewable Energy from Urban and Suburban Waste. Seeking input from academics, industry experts, national laboratories, government agencies, and other stakeholders, the RFI is designed to support early-stage research and development on technologies that can contribute to the maximization of U.S. biomass resources. Responses to the RFI must be submitted by 5:00 p.m. (EST) on January 18, 2019.
