Underground Hydrogen Storage Pilot Gets Funding Boost

The title of this post is the same as that of this article on Energy Live News.

This is the sub-heading.

New hydrogen storage tech could boost grid resilience and emissions cuts

These first three paragraphs add some details.

National Gas and Gravitricity have secured £500,000 from Ofgem to develop a new type of underground hydrogen storage.

The H2FlexiStore system, designed by Edinburgh-based energy storage firm Gravitricity, aims to store up to 100 tonnes of green hydrogen in lined geological shafts.

The technology, which could see a demonstrator built in 2026, is intended to offer a flexible, resilient solution to future hydrogen network needs.

The article also has an excellent graphic.

Note that it takes 55.2 MWh of electricity to generate a tonne of hydrogen, so a hundred tonnes of hydrogen would store 5.52 GWh of electricity as hydrogen.
