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

Tohoku team develops new electrolyte to support rechargeable calcium batteries

Green Car Congress

Scientists from Tohoku University have developed a new fluorine-free calcium (Ca) electrolyte based on a hydrogen (monocarborane) cluster that could potentially realize rechargeable Ca batteries. High-energy-density and low-cost calcium (Ca) batteries have been proposed as ‘beyond-Li-ion’ electrochemical energy storage devices.

Australia Goes All-in on Green Hydrogen

Cars That Think

For several months now, 20 teams of Australian high-school students have been designing fuel-cell cars to compete in the country’s inaugural Hydrogen Grand Prix. The task: make the most of a 30-watt fuel cell and 14 grams of hydrogen gas. Welcome to Australia, where a green-hydrogen boom is in full swing.
