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

Baker Institute report: China has positioned itself as a gatekeeper to the energy transition; nickel case study

Green Car Congress

Widely ignored, although gaining attention, is China’s strategic positioning as a crucial gatekeeper to several key “green” technologies, including battery energy storage to support electric vehicles (EVs)—specifically, battery electric vehicles (BEVs)—along with stationary storage for power grids.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

As she drives her electric vehicle to her mother’s house, Monique’s battery gauge indicates that it’s time to reenergize. The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. A battery that mitigates these problems is DARPA’s objective.

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

Green Car Congress

Lead author Aniruddh Mohan and colleagues wanted to develop a method that evaluated the life-cycle costs and benefits for two battery-powered ridesource fleets and a gasoline-powered one. The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version.

OSU team develops new aqueous lithium-iodine solar flow battery; 20% energy savings over Li-I batteries

Green Car Congress

After debuting the first solar air battery—a photo-assisted charging Li-O 2 battery—last fall ( earlier post ), researchers at The Ohio State University led by Professor Yiying Wu have now developed a new system combining a solar cell and a battery into a single device.
