Joint Letter Long-duration energy storage must be a pillar of Europe’s electrification and energy security strategy.
A coalition of industry stakeholders has published a joint letter calling on the European Commission to recognise long-duration energy storage (LDES) as a strategic component of Europe’s energy security and electrification agenda. The signatories urge the Commission to include LDES in upcoming policy initiatives, including the Electrification Action Plan and the EU energy security framework.
As electricity demand grows across industry, transport, heating, cooling, and digital infrastructure, Europe will require greater flexibility to balance an increasingly renewable-based power system. Long-duration energy storage, capable of delivering power for eight hours or more, can provide clean flexibility over extended periods, reducing reliance on fossil-fuel backup and improving the use of domestic renewable energy.
The letter calls on the Commission to recognise LDES in future policy frameworks, develop an EU roadmap for deployment, create lead markets for long-duration storage applications, and support investment frameworks that improve project bankability and revenue certainty.
The signatories argue that scaling LDES will strengthen energy security, support industrial electrification, and enhance Europe’s clean technology competitiveness.
