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

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

Green Car Congress

They used the model and the data to estimate the life cycle air pollution, greenhouse gas, and traffic externality benefits and costs of serving rides based on Chicago TNC trip data from 2019 to 2022 with fully electric vehicles. A paper on their work is published in the ACS journal Environmental Science & Technology. —Mohan et al.

Berkeley study finds self-driving electric taxi fleets in Manhattan would deliver significant cost and environmental benefits

Green Car Congress

Using models they built and data from more than 10 million taxi trips in New York City, they found that the cost of service provided by a fleet of shared automated electric vehicles (SAEVs) would be $0.29-$0.61 per revenue mile—an order of magnitude lower than the cost of service of present-day Manhattan taxis and $0.05–$0.08/mi

AeroVironment licenses PNNL EV smart charger controller technology

Green Car Congress

Under normal conditions, this stabilizing technology will be particularly important as the power grid is expected to rely more and more on variable renewable resources such as wind and solar technologies. If a million owners plug in their vehicles to recharge after work, it could cause a major strain on the grid.
