A Scottish underground hydrogen storage technology firm, in collaboration with a high-powered energy consortium including National Gas, has received £500,000 funding from Ofgem for their innovative underground hydrogen storage project known as H2FlexiStore. This project, developed by Edinburgh-based Gravitricity, aims to provide locationally flexible storage for up to 100 tonnes of green hydrogen in purpose-built underground shafts. The funding will support the design and modeling phase over the next six months, with potential for a demonstration project in 2023. The success of this project could lead to further funding for a technical demonstrator project to showcase the benefits of underground hydrogen storage. Martin Wright, co-founder of Gravitricity, highlighted the importance of such technologies in meeting the energy storage needs of current and future systems. The project also aligns with efforts like Project Union, which seeks to repurpose the gas grid for hydrogen use in the UK. Kelvin Shillinglaw from National Gas emphasized the project's significance in preparing the UK's gas networks for a hydrogen-powered future, promoting operational flexibility, cost reduction, and decarbonization of heat and power.
