By Lynn L. Bergeson On May 10, 2021, the U.S. Department of Energy (DOE) selected four research and development (R&D) projects focused on the interaction between promising biofuels and combustion engines. As part of the DOE Bioenergy Technologies Office’s Co-Optimization of Fuels & Engines (Co-Optima) initiative, the four projects will leverage National Laboratory capabilities that can bring biofuel-engine combinations closer to commercial adoption. Each project awardee will...

By Lynn L. Bergeson On November 13, 2020, DOE’s EERE announced that the Co-Optimization of Fuels & Engines (Co-Optima) initiative issued a call for white papers. The Co-Optima initiative focuses on the development of new high-performance fuels that, when combined with advanced combustion approaches, can increase energy efficiency and reduce the carbon footprint. The initiative is seeking white papers to leverage National Laboratory resources and overcome technical challenges to...

By Lynn L. Bergeson On May 1, 2018, the U.S. Department of Energy’s (DOE) Vehicle Technologies Office (VTO) and Bioenergy Technologies Office (BETO) announced a joint multi-topic funding opportunity for $12 million as part of the Co-Optimization of Fuels and Engines (Co-Optima) initiative. This collaborative research and development effort supports the research of fuel and engine innovation that maximize vehicle performance and fuel efficiency, and is accelerating the introduction of...

By Lynn L. Bergeson On April 18, 2018, the U.S. Department of Energy (DOE) announced the release of the Co-Optima FY2017 Year in Review.  The Co-Optima initiative is accelerating the introduction of efficient, clean, affordable, and scalable high-performance fuels by bringing together DOE’s Office of Energy Efficiency & Renewable Energy (EERE), national laboratories, universities, and industry and government stakeholders to collaborate on improvements to biofuels and the...

By Kathleen M. Roberts On February 15, 2018, the U.S. Department of Energy (DOE) announced the release of the Co-Optimization of Engines & Fuels (Co-Optima) report titled Fuel Blendstocks with the Potential to Optimize Future Gasoline Engine Performance (Fuel Blendstocks report), along with the companion report on Efficiency Merit Function for Spark Ignition Engines.  The Fuel Blendstocks report identifies eight blendstocks that have the potential to improve gasoline...
