Emissions Analytics argues that current Pareto-efficient solution for decarbonization would be hybrids, not BEVs, based on do-no-harm

Green Car Congress

On this basis, and of Pareto efficiency, Emissions Analytics argues, until battery-electric vehicles can reach certain performance characteristics, government and industry support should switch immediately from EVs to full hybrids to create maximum welfare. times the maximum permissible tailpipe particle mass emissions.

How do sodium-ion batteries charge within seconds – ET Auto

Baua Electric

Sodium-ion batteries have been of considerable interest due to sodium’s abundance compared to lithium, which is over 500 times less common. The new battery technology addresses some of the fundamental limitations of current sodium-ion batteries , such as lower power output and longer charging times.

New Flyer to start development of first 60' fuel cell hybrid bus in North America; introduces 40' battery-electric bus

Green Car Congress

is developing the first North American designed and built 60-foot battery-electric/fuel cell hybrid bus that will operate in daily service. The electric drive bus will allow the fuel cell to operate at a relative steady-state, while the batteries will be able to both capture breaking energy and provide power for acceleration.

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.

DTF: Diesel dominates commercial truck, transit and school bus fleets in US

Green Car Congress

Other fuels that play a role in commercial trucking include gasoline (23%) and compressed natural gas (0.4%). Electric and other categories each register less than 1%. About 32% of all electric trucks nationwide are in California, where for every electric truck there are about 300 diesel trucks (all years, Classes 3-8).

BIT researchers use high energy density material in electrode to enhance Li-S battery performance

Green Car Congress

To develop higher capacity batteries, researchers have looked to lithium-sulfur batteries because of sulfur’s high theoretical capacity and energy density. It also consumes fresh lithium and electrolytes, and reduces battery performance. It holds great promise in gas storage and separation, catalysis and energy storage.
