Why Hydrogen Storage?
Hydrogen and other long-term energy storage technologies will be needed to balance out intermittent renewable generation and provide a secure long term means of storage to address seasonal variations in demand.
The volumes required for seasonal storage in the UK will mean the utilisation of subsurface geological formations such as salt caverns or depleted gas reservoirs for storing hydrogen.
This large scale hydrogen storage will ensure continuity of energy supply all year round irrespective of demand or weather conditions and provide the UK with vital energy security.
How we use Hydrogen storage
Hydrogen can be stored securely underground in a geological formations in the same way that natural gas currently is today. During periods when renewable generation is high, hydrogen can be produced and injected into these formations. Then when renewable output is too low to meet demand, the stored hydrogen can used to power flexible generation plant, providing a secure low carbon source of electricity for balancing the grid.
