Multiscale Analysis for

Underground Hydrogen
Storage

The research group uses innovative technology to model and design safe storage of hydrogen underground in depleted gas reservoirs or aquifers , providing a large-scale energy storage solution . By converting excess renewable energy into hydrogen , fluctuations in supply can be mitigated . The team ’ s extensive research and advanced capabilities enable accurate prediction and optimisation of Underground Hydrogen Storage ( UHS ) systems .

Competitive Advantage

• A groundbreaking solution for energy storage through modelling UHS – involves storing hydrogen in subsurface aquifers or depleted gas reservoirs , providing a viable long-term energy storage option
• UHS taps into the potential of renewable energy sources like wind and solar power – these sources often face fluctuations in energy supply on a daily or seasonal basis , so UHS mitigates these fluctuations by converting excess electrical energy from renewables into hydrogen energy and storing it in large volumes
• Extensive research into the interaction between rock , water , and hydrogen in subsurface environments – facilitates the design of effective UHS systems
• Cutting-edge multiphase laboratory setup and X-ray scanning facilities enables monitoring and imaging of hydrogen transport phenomena and its interaction with the host rock at microscale – capability to upscale the outcome to larger scales , which allows accurate prediction of hydrogen ’ s behaviour in the subsurface , aiding the design and optimisation of UHS systems
