Energy storage for electricity generation is widely recognised as an important component of the Net Zero economy, and there are several potential technologies available for energy storage. Hydrogen has unique features as a means of energy storage, since as a clean-burning gas it can be transported through existing infrastructure and stored safely for long periods of time, if necessary. We welcome the Government’s recognition of the potential role of hydrogen as an important means of energy storage. The Government should continue to provide the necessary policy support and infrastructure for grid-scale energy storage technologies. Findings from hydrogen energy storage trials should be recorded and shared between trials to ensure that as much is learned as possible.
