The only downside of this type of energy storage system is the high capital cost involved with buying and installing the main components. The characteristics exhibited by mechanical energy storage systems makes them ideal for load levelling as well as storage [7]. In order to reduce the exergy loss of high-pressure storage, an isobaric
We Don''t Need to Reinvent Energy Storage for the Renewables Era
Their idea is to build reservoirs on the bottom of the ocean under high pressure, like a submarine. When there is a surplus of energy, the reservoirs can be emptied against the water pressure, using pumps. When energy is needed, the reservoirs are opened, and pressure pushes water inside, powering a turbine to generate electricity.
