About

The LDES Council is a global non-profit with over 60 members in 19 countries. The Council works to accelerate the decarbonization of our world through the acceleration of long-duration energy storage. It provides member-driven, fact-based guidance and research to governments, grid operators and major electricity users on the deployment of long-duration energy storage for society's benefit.

The LDES Council Mission

The LDES Council’s mission is to replace the use of fossil fuels to meet peak demand by accelerating the market for long duration energy storage. This will cut global emissions and ensure flexibility in electricity supply, while providing affordable, reliable, and resilient clean energy solutions. The Council’s industry experts provide fact-based guidance to Governments and grid operators in the deployment of long duration energy storage to help achieve NetZero for electric grids by 2040. The Council provides education and advocacy services to help advance the adoption of LDES and accelerate carbon neutrality. The Council covers a wide range of LDES technologies and its members span a wide spectrum of innovation, including mechanical, thermal, electrochemical and chemical solutions.

Governance of the LDES Council

All members of the LDES Council have voting rights. Members elect a Board of Directors consisting of five members, including the Chair who acts in a non-executive role. The Board of Directors is then in charge of setting the long-term vision for the Council, as well as research priorities and areas of focus. Two Presidents play the executive role on behalf of the Council, with well-defined non-overlapping responsibilities, defined by the Board of Directors. Each year only one of the Presidents is replaced to ensure continuity, with one anchor member and one technology provider in place at all times. As part of the Council all members have the possibility to join Working groups (e.g., on regulatory/market mechanisms, investment, recruitment) and to be an active participant in advancing the mission of the Council.
