Working Group 2
Storage technologies and system flexibilities

Work Group 2 addresses the technological and market developments related to energy storage solutions to ensure the required level of flexibility for the transmission and distribution of electricity. It will consider all the different energy storage options, including power-to-power, power-to-gas, hydro and marine storage, CAES, thermal mass of buildings, hot water storage, etc., and their direct or indirect interface and interaction to the power networks.

WG2 covers the entire value chain of all energy storage options, starting from the development and demonstration of new materials, technologies and solutions, and addressing their integration into the overall energy system, the evaluation of their impact on flexibility and the related costs/benefits.

District storage paper
Working Group 2 - December 2025 District energy storage systems (DESS) are identified as a critical enabling technology for achieving deep decarbonisation, enhancing grid stability, and improving energy resilience at the local level. Scaling their deployment from pilot projects to industrial use requires a concerted, multi-faceted strategy that addresses financial, regulatory, technical, and societal challenges simultaneously. The promise of a decentralised, renewable energy future hinges on this DESS critical component. If DESS is to be adopted on a large scale, then a joined-up approach needs to be applied across policy, finance, technology, and society.
