Gravitricity to deploy prototype underground hydrogen storage system
Gravitricity, an Edinburgh-based storage specialist, aims to develop the first full-scale demonstration of its underground hydrogen storage solution by working with structural engineering contractor VSL Systems UK.
World’s largest underground hydrogen storage project
Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.
The burgeoning underground scene of hydrogen storage
Underground hydrogen storage seems to be coming up a lot lately, and with the burgeoning hydrogen industry needing somewhere to store itself, it’s not hard to understand why. One of the countries with the best credentials for the future hydrogen economy is Australia. A newly published report has quantified the country’s “massive opportunity” for underground hydrogen storage.
Key challenges for underground hydrogen storage
An international research team has presented challenges and knowledge gaps in the implementation of large scale underground storage of hydrogen. The main issues associated with this technology relate to the fluid flow behavior of hydrogen in subsurface reservoirs, geochemical reactions caused by hydrogen injection, biotic reactions caused by excess hydrogen, and the geomechanical response of the subsurface to hydrogen storage.
