While electric cars are coming off the assembly line in ever-growing numbers, vehicles with internal combustion engines using fuels produced mainly from petroleum will continue to make up a large share of the automotive market for years to come. What innovations can make these engines and fuels as environmentally friendly and energy efficient as possible?

The U.S. Department of Energy Bioenergy Technologies and Vehicle Technologies Offices' Co-Optimization of Fuels & Engines (Co-Optima) initiative is accelerating the introduction of efficient, clean, affordable, and scalable high-performance vehicle fuels and engines. A new Co-Optima Capstone Webinar Series highlights key takeaways from the breakthrough initiative.

The series kicks off on March 25, 2021 with a session that asks, “How can co-optimized fuels and spark-ignition (SI) engines enhance efficiency while reducing carbon emissions of light-duty (LD) passenger vehicles?” Presenters Daniel Gaspar of Pacific Northwest National Laboratory and Jim Szybist of Oak Ridge National Laboratory will describe Co-Optima’s identification of biofuel blend components chosen to improve key fuel properties, as well as their potential impacts on the sustainability of LD SI fuels and engines.

Attendees can register online for the following Co-Optima Capstone sessions:

March 25 - How can co-optimized fuels and SI engines enhance efficiency while reducing carbon emissions of LD passenger vehicles?

April 29 - How can fuels and combustion reduce pollutants from future diesel engines?

May 27 - What environmental and economic benefits might be realized by co-optimizing fuels and SI engines for LD passenger vehicles?

June 24 - What environmental and economic benefits might be realized by co-optimizing fuels and engines for medium-duty (MD) and heavy-duty (HD) commercial vehicles?

August 26 - What unconventional engine-fuel combinations show the greatest promise for efficiency improvements beyond current LD/MD/HD technologies?

September 30 - Co-Optimization of Fuels & Engines past, present and future: What did we learn and where do we go next?
