The missing piece of the energy system puzzle
Haldane Energy is redefining electricity storage to help deliver the secure and flexible energy system the UK needs.
Capture
We use excess renewable power to create green hydrogen from water.
Store
The hydrogen is then kept safely in underground salt caverns, ready for when it’s needed.
Convert
The stored hydrogen is then converted into electricity for the grid.
The UK’s leading developer of hydrogen-derived long duration electricity storage (H₂-LDES)
How our technology worksWhen renewables exceed demand, we store the surplus as hydrogen and release it back as power when demand rises.
