Auburn University leads $2M DOE Co-Optima project to evaluate renewable butyl acetate as diesel fuel additive

Green Car Congress

Auburn University researchers are leading a $2-million US Department of Energy Co-Optima project ( earlier post ) that will evaluate renewable butyl acetate (BA) as a bio-based fuel additive that can be blended with diesel fuel to reduce soot and greenhouse gas emissions and yield cleaner engine operation in cold-weather conditions.

Cepsa to invest €3B in Andalusia to build the largest green hydrogen hub in Europe; additional €2B for renewable power

Green Car Congress

To generate the renewable electricity needed to feed production of green hydrogen, Cepsa will develop a 3GW portfolio of wind and solar energy projects with an additional €2-billion investment. It also expects Spain to become a net exporter of renewable hydrogen. Of these, 1,000 will be direct employment opportunities.

Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

While there is global potential to generate renewable energy at costs already competitive with fossil fuels, a means of storing and transporting this energy at a very large scale is a roadblock to large-scale investment, development and deployment. Generation 2 moves the Haber-Bosch process to renewable sources of hydrogen.

Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

Phil Ansell, an aerospace engineer at the University of Illinois Urbana-Champaign, modeled the life cycle carbon dioxide equivalent emissions of liquid hydrogen production required to meet the fuel needs of Chicago’s O’Hare International Airport (ORD) with today’s electric grid mix. Ansell presented his findings at AIAA Aviation 2023 in June.
