Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

However, few studies have used real-world rideshare trip data in their estimates, or included additional assessments of air pollution and traffic impacts, from the switch. The researchers collected simulated rides provided by three fleets: gasoline-powered, and electric-powered with either 40 kWh or 60 kWh battery packs.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

Researchers from Japan’s NIMS (National Institute for Materials Science), the University of Tokyo and Hiroshima University have jointly conducted a techno-economic analysis for hydrogen production from photovoltaic power generation (PV) utilizing a battery-assisted electrolyzer. This approximately converts to US$1.92 to US$3.00/kg

Hawaii study finds vehicle-to-grid discharge detrimental to EV batteries

Green Car Congress

Results of a study by a team at the Hawaii Natural Energy Institute, SOEST, University of Hawaii at Manoa, suggest that the additional cycling to discharge vehicle batteries to the power grid in a vehicle-to-grid (V2G) scenario, even at constant power, is detrimental to EV battery cell performance.
