Oil and gas major TotalEnergies, thermal energy storage system company 1414 Degrees and six other companies have joined the Long Duration Energy Storage (LDES) Council.

The CEO-led organisation, founded at COP26 last year, said the new members have joined towards the end of quarter three.

The LDES Council has welcomed four new technology members – companies providing long duration energy storage solutions – and four new anchor members – companies with interests or operations within the broader energy sector.

The new technology members are: molten silicon thermal energy storage system (TESS) provider 1414 Degrees, high-density hydro energy storage startup RheEnergise, broader heating solutions company Thermowatt and Mine Storage, a company which says it operates medium-to-large-scale power storage solutions in underground mines.
