With solar and wind installation breaking new records each year, countries with ambitious plans for these renewable power-generation technologies must consider the best ways to integrate variable renewables onto the grid. Electricity storage is a key option available
READ MOREEnergy storage is the capture of energy produced at one time for use at a later time Renewable energy sources like wind and solar energy vary. So at times when they provide little power, they need to be supplemented with other forms of energy to meet energy demand. Compressed-air energy storage plants can take in the surplus energy output
READ MOREUsing energy storage to backup renewable energy generation rather than increasing generation capacity reserves – generation costs should be more manageable (e.g. reduced carbon emissions), which in turn, should result in the price cut for the end-users [53].
