Study: EV efficiency gains could cut grid demand, save billions

Green Car Reports

EVs could end up using a lot of electricity, but efficiency improvements to support them could significantly reduce the need for new grid infrastructure, cut energy usage, and potentially save consumers billions of dollars, according to a new study from research firm EPRI and the Natural Resources Defense Council (NRDC).

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. Compared with a seasonal battery, this new design is especially adept at short- to medium-term grid energy storage over 12 to 24 hours.

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.
