Abstract
There is provided an energy storage system. The system includes a storage tank, a reservoir connected to the storage tank configured to store fluid and exchange the stored fluid with the storage tank, at least one path configured to transfer the stored fluid between the storage tank and the reservoir, a pump configured to inject the stored fluid into the storage tank and compress air in the storage tank, and a generator configured to generate electricity by using the injected fluid transferred from the storage tank to the reservoir.
Claims6
A method of storing and recovering energy, the method comprising:
- providing fluid in a reservoir;
- injecting the fluid into a storage tank;
- compressing air in the storage tank;
- maintaining pressure inside the storage tank;
- discharging the injected fluid in the storage tank using the compressed air to the reservoir;
- and
- generating electricity using the discharged fluid,
- wherein the method further comprises injecting compressor air generated by a compressor into the storage tank,
- wherein the compressing of the air comprises compressing the air in the storage tank until the compressed air in the storage tank reaches a previously determined pressure, and
- wherein the injecting of the fluid into the storage tank is performed after the injecting of the compressor air into the storage tank.
