Scottish underground hydrogen storage project awarded £500k
National Gas, an independent gas supplier in the UK, was awarded the funds by energy regulator Ofgem to develop the project alongside Edinburgh-based energy storage specialists Gravitricity, and could see a pilot project built as early as next year.
The storage system, known as H2FlexiStore, is designed to hold up to 100 tonnes of green hydrogen in purpose-built underground shafts, and can be located anywhere it is required – for example, as part of the National Gas network, or next to large industrial sites which consume a lot of energy.

The funds were awarded from Ofgem's Strategic Innovation Fund and come after a feasibility study carried out by National Gas in 2024 identified the H2FlexiStore as the preferred technology to provide hydrogen storage which can be used in any location.

'This support from Ofgem, enables us to prepare both technically and commercially for the delivery of a demonstration project next year and the early commercial projects within our existing pipeline of opportunities.'

Wright added that the technology could be of particular use in Scotland, "where there are no alternative or existing geological storage solutions".
Kevin Shillinglaw, innovation analyst at National Gas, said: 'This project is a critical step forward in ensuring the UK's gas networks are ready for a hydrogen-powered future.
'By embedding resilience with operational hydrogen storage directly into the transmission system, we can maintain operational flexibility, reduce costs for consumers, and support the decarbonisation of heat and power."
