Liquid Air Storage
The worldwide energy potential from renewable sources such as solar and wind is huge, but can be unreliable.
Various processes exist to capture excess renewable energy that would otherwise be lost when the electricity is grid is operating at its maximum.
A thermal store of energy is required to supplement the grid when demand is high. Liquid air can be used at the medium for the thermal energy storage. Whilst the required storage temperatures are low circa -196°C, the constraints for boil-off can be more relaxed.
Whessoe were designing low pressure Liquid Oxygen & Liquid Nitrogen tanks back in 1955, so this new spin on the old technology is an exciting new development.
