Committee to take evidence on technologies for long-duration energy storage

The House of Lords Science and Technology Committee will hold its second evidence session for its inquiry into long-duration energy storage.

The Committee will hear from experts across different technological areas for long-duration energy storage, including representatives from the Faraday Institution, Thermal Storage UK, and winners of the Government’s Long Duration Energy Storage competition.

The session will focus on the different technologies that can provide long-duration energy storage for the UK grid, including batteries, hydrogen, and thermal storage technologies. Members will explore the advantages and disadvantages, as well as the technology readiness level, for various proposed longer duration energy storage solutions. They will ask about the technical, practical, and commercial barriers to larger-scale deployment for these technologies, and whether any policy change is required to support them more effectively.
