Seminal BID3 study on long-duration storage in GB just published!

We pulled out the stops in this analysis, throwing the full power of BID3, with hydrogen networks, electrolysis and storage, reserve co-optimisation and multiple transmission zones all optimised in the Auto Build

Key findings

For the GB system, the extensive study using BID3 found that:

  • the future energy system will have extended periods of days or weeks where there are excesses or shortfalls of renewable output
  • access to longer duration storage solutions to address these electricity imbalances can reduce system costs by between £13bn and £24bn
  • based on the technology cost assumptions, the larger savings arise when flexibility is delivered through a combination of electrolysis, hydrogen storage and hydrogen CCGTs, since system balancing still relies on large amounts of dispatchable low-carbon thermal capacity during these long periods of low renewable generation and high demand; and
  • between 12 and 21 GW of medium (6hr to 12hr) and long duration storage (>12hr) is deployed across the scenarios and around 3GW of LDS (such as pumped storage, compressed air energy storage (CAES) or liquid air energy storage (LAES)) is seen as a low regrets investment to mitigate some of the uncertainty around emerging, innovative, novel solutions like hydrogen in the near-term.
