Edinburgh-based underground energy storage business Gravitricity has signed a Memorandum of Understanding with infrastructure company VSL Systems UK to design lined rock shafts to store hydrogen.
They plan to build a scale demonstrator in the next 24 months, ahead of a nationwide commercial rollout.
Gravitricity believes that its FlexiStore technology is a ‘goldilocks’ solution to the future challenge of green hydrogen storage – offering a system that is larger and more secure than above ground hydrogen storage, and more flexible than subterranean salt caverns; the two most commonly-proposed alternatives.
