National Gas has secured £500,000 from Ofgem to develop a new underground hydrogen storage system called H2FlexiStore, in collaboration with Gravitricity and other partners. The project involves designing a system capable of holding 100 tonnes of green hydrogen in purpose-built underground shafts. This initiative, funded by Ofgem's Strategic Innovation Fund, aims to enhance the resilience and operational efficiency of the hydrogen gas network, supporting the transition to green hydrogen as a fuel. The technology, developed by Gravitricity, could facilitate the repurposing of the existing gas grid for hydrogen, creating a UK hydrogen backbone. If successful, the project could lead to commercial deployment of the technology, providing cost-effective resilience within current and future energy systems. The innovative storage solution is particularly crucial for regions like Scotland, where existing geological storage options are limited. Additionally, Gravitricity anticipates the technology's deployment in export markets as countries seek their own hydrogen solutions. The potential for Scotland to produce and export green hydrogen further underscores the significance of this project in the broader energy landscape.
