Green Energy Storage
Many nations have the potential of being energy-independent through renewable energy. The missing piece of the energy puzzle, however, is storing the energy at TWh-scale; dispatchable at any time, in any season. Energy Storage will power the Green Energy transition
Hydrogen Storage
Our system stores energy in underground salt caverns – of which there are thousands in existence already.
Making use of these relics of the fossil fuel industry uses fewer resources in setup and operation then alternate battery solutions.
Salt Caverns have been used historically to store natural gas and petroleum, and in the past 40 years to store Compressed Air.
Our technologies have higher efficiencies, and the capability to also safely store Hydrogen.
Hydrogen Ready
What can carry Hydrogen can also carry air – but not vice versa. We retrofit existing air caverns and pipes to accommodate for the specific storage requirements of Hydrogen; whether produced by us on site via electrolysis, or imported.
How It Works
- Renewable energy or excess energy from the grid is used to drive air through a compressor.
- The pressurised air is stored in underground salt caverns until there is demand for it.
- When required, the air is delivered back to the surface where it is heated and expanded.
- The expanded air is sent through a turbine, driving a generator and producing power.
