In addition, there's the idea of using pressurized underground aquifers as an energy store (basically, using bending and lifting of the overlying rocks to store the energy when pressurized water is pumped underground). The pressure can be transfered to a clean seawater stream by a device called a pressure exchanger, which can then be fed into a reverse osmosis plant.
