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.

Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

During discharge, liquid bromine is reduced to hydrobromic acid along the lower solid graphite electrode, and hydrogen is oxidized at the upper porous electrode. MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. Credit: Braff et al.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) Recent years have seen the construction of large lithium-ion battery farms that do just that.

ENGIE launches fleet of 50 hydrogen fuel cell Renault Kangoo Z.E. vans, inaugurates first alternative multi-fuel station in France

Green Car Congress

France-based global energy and services group ENGIE has launched a fleet of 50 hydrogen-powered Renault Kangoo Z.E. Equipped with hydrogen fuel cell range extender systems by Symbio, the these electric vehicles neither produce particles nor gas emissions and are further enhanced with a reduced recharge time and greater autonomy.
