The U.S. Department of Energy Bioenergy Technologies Office (BETO) transportation biofuels research aims to accelerate the production of climate-friendly, sustainable fuels capable of decarbonizing heavy modes of transportation. Made from widely available domestic feedstocks and advanced refining technologies, energy-dense biofuels provide a pathway for lowering greenhouse gas emissions in the aviation and maritime sectors while invigorating the bioeconomy.
