Denmark’s largest battery – one step closer to storing green power in stones

The technology, which stores electrical energy as heat in stones, is called GridScale, and could become a cheap and efficient alternative to storing power from solar and wind in lithium-based batteries. While lithium batteries are only cost-effective for the supply of energy for short periods of up to four hours, a GridScale electricity storage system will cost effectively support electricity supply for longer periods – up to about a week.…

Lawsuit-Supporting Academic: Attribution Science Was Designed Specifically To Bolster Climate Litigation

A prominent academic with direct ties to the climate litigation campaign confirmed in a recent E&E News article that so-called “climate attribution science” was designed specifically to support lawsuits against major energy companies.
