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.

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.

SAE International publishes TIR J2954/2 for wireless charging of heavy-duty EVs; static and dynamic WPT

Green Car Congress

SAE International has published the first Technical Information Report (TIR) that specifies, in a single document, both the electric vehicle- and ground-system requirements for heavy-duty (HD) wireless charging of electric vehicles (EV). The technology is a safe and efficient method for transferring power from the AC grid supply to the HD EV.

NERC: high probability of insufficient resources to meet electricity demand as early as Summer 2022 in parts of US

Green Car Congress

Findings from the North American Electric Reliability Corporation’s (NERC’s) 2021 Long-Term Reliability Assessment (LTRA) indicate there is a high probability of insufficient resources and energy to serve electricity demand, as early as Summer 2022, in many parts of the Western Interconnection.

Practical aspects of off-grid EV charging

Charged EVs

An off-grid energy system basically consists of just four key components: 1) a battery to store energy; 2) one or more renewable energy sources (e.g. An off-grid energy system basically consists of just four key components: 1) a battery to store energy; 2) one or more renewable energy sources (e.g. from the battery. from the battery.
