What is a wave-driven compressed air energy storage system?
This paper proposes a novel wave-driven compressed air energy storage (W-CAES) system. This system integrates a WEC based on a hydraulic PTO component and a liquid-piston-based compressed air energy storage system to convert wave energy and store it directly as compressed air.
What is compressed air energy storage (CAES)?
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
Can a liquid piston based compressed air energy storage system improve utilization performance?
These gaps and challenges motivate researchers to investigate the potential of incorporating the liquid piston-based compressed air energy storage system with a hydraulic PTO system to enhance the utilization performance of a wave energy conversion system. This paper proposes a novel wave-driven compressed air energy storage (W-CAES) system.
Does wave energy converter and compression chamber affect system performance?
Furthermore, the impacts of geometric parameters of the wave energy converter and compression chamber on the system performance were investigated. Results indicated that energy storage power was improved as the hydraulic cylinder area and storage pressure increased.
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.
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.
