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

Fraunhofer analysis finds battery-electric trucks have energy cost advantage over hydrogen trucks

Green Car Congress

In addition, the expected amount of green hydrogen is limited, even with large-scale imports, and should thus be available to energy-rich industries, as the current Fraunhofer study also summarizes. They exceed the purchase costs many times over. —Catharina Modahl-Nilsson, Chief Technical Officer of TRATON Group.

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

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

We learned that lesson too well at the start of the pandemic, when demand for toilet paper, disinfecting wipes, masks, and ventilators outstripped the available supply. That need for balance is true of electric power grids, too. Today, chip shortages continue to disrupt the consumer electronics, automobile, and other sectors.
