A new report from DOE describes the innovative collaborative research that has been completed in the first year of the Co-Optima initiative. The report spotlights approximately 30 of the scientific and technical advances that researchers made in the initiative’s first year, including:



  • Identifying more than 40 candidate blendstocks that can be produced from biomass and blended with petroleum to increase the efficiency of downsized turbocharged spark ignition (SI) engines
  • Conducting state-of-the-art experiments to identify the effects of individual fuel properties on SI engine efficiency
  • Establishing a publicly-accessible database of fuel property information for approximately 400 bio- and petroleum-derived blendstocks
  • Developing advanced modeling tools and conducting high-fidelity simulations to complement engine experiments
  • Conducting lifecycle and techno-economic analyses on 20 representative bio-blendstocks to assess their performance across 15 scalability, affordability, and sustainability metrics.

Sandia National Laboratories is one of the nine national laboratories collaborating on the project, brought together by DOE’s Office of Energy Efficiency & Renewable Energy.
