Oscillating Water Column Wave Energy Technology: A State of the Art Review on Hydrodynamic, Hybrid Integration, and Life Cycle Sustainability

Ocean wave energy, as one of the high-potential renewable energy sources, has received widespread attention in recent decades. Among wave energy conversion technologies, the Oscillating Water Column (OWC) is recognized as one of the most promising solutions due to its simple structure, limited moving parts, and the ability to be integrated with coastal structures. In this paper, we review the technology with a comprehensive and forward-looking approach. This study provides a comprehensive and forward-looking review of the technology, covering its operating principles, configuration types (fixed and floating), self-compensating turbine types (Wells, impulse, and bi-radial), advantages and disadvantages, potential applications in power generation, water desalination, and integration with offshore wind energy, as well as economic and environmental perspectives.
