RE: Response to Request for Information (RFI) DE-FOA-0001460 Category 1 – The Renewable Fuels Association (RFA) appreciates the opportunity to provide these comments in response to the Office of Energy Efficiency & Renewable Energy’s (EERE) Request for Information on Co-Optimization of Fuels and Engines (“Optima”). [RFI DE-FOA-0001460]

RFA is the leading trade association for the nation’s ethanol industry. Its mission is to advance the development, production, and use of fuel ethanol by strengthening America’s renewable fuels industry and raising awareness about the benefits of biofuels. Founded in 1981, RFA serves as the premier meeting ground for industry leaders and supporters. RFA’s 300-plus members are working to help America become cleaner, safer, more energy secure, and economically vibrant. As an initial matter, RFA strongly supports the Optima initiative and encourages the Department of Energy (DOE) to continue applying appropriate resources and attention to this important program. We agree that co-optimization of future fuels and engines is an essential strategy for achieving national objectives related to energy conservation, carbon emissions reduction, and energy security. The Optima program is innovative and proactive, and the DOE should be applauded for undertaking such a bold and progressive initiative. Read Full
