Storelectric is a multi-award-winning, electricity storage company aiming to transform the global energy market by providing a proprietary-technology solution for storing and using renewable energy.
The principle of operation of a CAES plant is inherently simple. When more electricity is being generated than wanted, it is used to compress air. This air is stored underground and let out to drive a turbine when electricity is needed. Pressures used vary, but a typical value is ~70 bar (~30 times the pressure of a car tyre). Depending on the system, the electricity could be stored indefinitely, though the typical use is on the order of hours.
You can potentially build a CAES plant wherever there is a suitable storage space. Ideally, this storage space should be near to:
• Significant intermittent supply – wind and solar farms, for example.
• Demand – population or industrial centres.
• Existing connections to the grid.
At present, Storelectric plans to use underground Salt Caverns as this typography is perfect for CAES plants and there are plenty of suitable locations for CAES plants around the world.
