How does a wave-driven compressed air energy storage system work?
This paper proposes a novel wave-driven compressed air energy storage (W-CAES) system that combines a heaving buoy wave energy converter with compressed air energy storage. Wave drives the heaving buoy to convert the wave energy to mechanical work that pumps water into a water-air compression chamber to form a liquid piston compressor.
What is ocean wave energy?
An ocean wave is energy in motion through water. This energy, in the form of kinetic or potential energy, can be harvested using wave energy converters, or WECs. How Much Wave Energy is Available?
What is the Marine Energy Atlas?
The Marine Energy Atlas shows area of wave energy around the United States. What is a Wave Energy Converter? Wave energy converters (WECs) are devices that convert the kinetic and potential energy associated with a moving ocean wave into useful mechanical or electrical energy.
How does wave condition affect energy storage power?
Energy storage power was almost proportional to the hydraulic cylinder area, with an upper limit being imposed by the wave condition. Nevertheless, the maximum storage pressure had an inverse relationship with the hydraulic cylinder area, which decreased energy density under the same wave condition.
What is a wave energy converter?
This class of wave energy converter comes in two different flavors. In one type, the device rests on or near the seafloor and relies on pressure fluctuations as a wave passes overhead to flex a pliable material such as a air bladder and squeeze a fluid to drive a turbine or some other power take-off unit.
What is the energy storage power of a W-CAES system?
It was seen that the energy storage power of the proposed W-CAES system with the same geometry dimensions was larger than that of the 10 kW combined with the heaving buoy prototype in the literature when wave energy was <15 kW.
