Noon Energy, developer of a novel carbon-oxygen battery for long-duration storage, has raised US$28 million in a Series A funding round.

Austin-based potassium-ion battery startup Group1 says its technology has comparable energy density to lithium iron phosphate (LFP), and that it is aiming for a large-scale launch of its product by 2027.

The first commercial sand-based thermal energy storage system in the world has started operating in Finland, developed by Polar Night Energy.

Energy Dome has scored its first commercial licensing agreement for its carbon dioxide-based energy storage solution.

A “novel and innovative” technology which uses CO2 as a medium to store energy could be made using off-the-shelf equipment and made available to the market as early as next year, the company behind it has said. 

An agreement has been signed which could lead to a multi-gigawatt lithium-ion battery cell manufacturing facility being built near Chennai, India, using 24M’s advanced ‘SemiSolid’ electrode technology. 

A 2.5MW / 4MWh demonstration system using novel energy storage technology based on a “carbon dioxide battery” has begun construction in Sardinia, Italy.
