US DOE awards US$1 million in funding to four Co-Optima projects

The US Department of Energy (DOE) has announced the selection of four projects totaling US$1 million to conduct cutting-edge applied research and development concerning the interaction between promising biofuels and combustion engines. The projects will leverage a range of National Laboratory capabilities as part of the Co-Optimization of Fuels & Engines (Co-Optima) initiative and aim to help bring these fuel-engine combinations closer to commercial adoption.

The US Department of Energy (DOE) has selected four Co-Optima projects totaling US$1 million to conduct cutting-edge applied research and development concerning the interaction between promising biofuels and combustion engines.

The Co-Optima initiative provides the American industry with the scientific knowledge needed to maximize vehicle performance and efficiency, leverage domestic fuel resources, and reduce life cycle emissions.

The DOE has awarded funding to four Co-Optima projects. Each awardee will receive up to US$250 000 in National Laboratory assistance for experimental or computational projects that leverage innovative capabilities in the areas of bio-blendstock fuel property, production, and combustion performance research.

The projects will also focus on the impacts of the adoption of co-optimized fuel-engine combinations. Each of the awardees has committed to a 20 percent cost-share contribution.

The four projects are:

  • Aramco Services Company in Houston, Texas (TX), Marathon Petroleum Company in Findlay, Ohio (OH), and Caterpillar in Peoria, Illinois (IL) will work with Argonne National Laboratory (ANL) to identify bio-blendstock characteristics, including carbon number and molecular structure, that will provide the best 87 anti-knock index gasoline for heavy-duty gasoline compression ignition engines.
  • The Coordinating Research Council in Alpharetta, Georgia (GA) will work with Pacific Northwest National Laboratory (PNNL) and Los Alamos National Laboratory (LANL) to develop an isotope ratio mass spectrometry method as a cost-effective means to identify renewable content in co-processed biomass- and fossil-derived fuels.
  • Cummins in Columbus, Indiana (IN) will work with Oak Ridge National Laboratory (ORNL) to develop a deeper fundamental understanding of how physical and chemical fuel properties affect mixing-controlled compression ignition combustion in medium-duty engines through computational fluid dynamics simulations.
  • Shell in Houston, Texas (TX) will work with ORNL and ANL to quantify how fuel volatility can be used to increase anti-knock performance, in order to increase engine efficiency and the use of biomass-derived fuels.

Sponsored by the DOE Office of Energy Efficiency and Renewable Energy’s (EERE’s) Vehicle Technologies Office (VETO) and Bioenergy Technologies Office (BETO), Co-Optima partners include ANL, LANL, PNNL, ORNL, Idaho National Laboratory, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, National Renewable Energy Laboratory, and Sandia National Laboratories, as well as more than 20 university and industry partners.

EERE is focused on decarbonizing the transportation sector, the single largest source of domestic greenhouse gas emissions. EERE’s work in boosting fuel economy and vehicle performance, while reducing emissions, is central to the bold energy and climate goals laid out by President Biden: building a 100 percent clean energy economy and reaching net-zero emissions no later than 2050.
