LDES Council accelerates international expansion as membership grows

2 MAY 2023 – BRUSSELS – The Long Duration Energy Storage Council (“LDES Council”), has today announced that eight new members have joined the non-profit organization, to support its mission in accelerating global decarbonization through the growth of long duration energy storage (LDES).

The LDES Council launched in November 2021 and has tripled in size since its launch, with over 60 diverse companies in regions across the world representing the full energy value chain – including technology innovators, equipment providers, renewable energy companies, utilities, investors, and end-users.

Joining the LDES Council most recently are five technology members and three anchor members. Anchor members include: Diamond Generating Corporation, Occidental, and Sociedad Química y Minera de Chile (SQM). Technology members include: Antora Energy, Build to ZeroLargo Clean Energy, Noon Energy, and Rondo Energy.

Their pioneering technologies include thermal energy storage technologies, chemicals, and clean energy solutions that support the energy transition and innovative long duration energy storage products and services.

LDES Council chief executive officer Julia Souder, said: “Renewable energy is growing exponentially around the world, but this must be matched by the growth of LDES to support wind and solar at times of low generation or high demand. These new members demonstrate the breadth of LDES solutions that will play a vital role in decarbonising key developing markets across Latin America, Asia Pacific, and MENA regions.”

The LDES Council continues to lead the world in accelerating the deployment of long duration energy storage.
