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

Green Car Congress

The joint research team designed an integrated system capable of adjusting the amount of battery charge/discharge and the amount of electrolysis hydrogen production in relation to the amount of solar power generated. The team then evaluated the economic feasibility of the system. Credit: NIMS. 2018.11.119 ).

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern.

Australia Goes All-in on Green Hydrogen

Cars That Think

The carbon-free rigs will pack 50 kilos of hydrogen zapped from water using electricity from the refinery’s dedicated solar power plant. Resource-poor Asian neighbors such as Japan and Korea are also counting on Aussie green hydrogen to help get them off fossil fuels in the decades ahead. Why a hydrogen truck?

UC Davis researchers suggest we may be at the beginning of a real hydrogen transition in transportation

Green Car Congress

Low-cost shale gas has improved the prospects for natural gas-derived hydrogen, especially in the United States, where it is a major force in the resurgence of federal interest in hydrogen energy. Global public support now totals about $1 billion per year, leveraging many times that amount in private funds.
