A flexible oscillating water column is a device that improves oscillating water column technology through use of a flexible material with advanced controls to convert energy content in ocean waves to electric power. The flexible oscillating water column is integrated in coastal structures such as break waters. As water waves rise inside a chamber, the air flows into a turbine to generate electricity. The flexible oscillating water column reduces the cost of electricity.

A power generation system based on wave-compressed air energy storage. Direct-drive air compression units each with a hollow buoy (10) at the bottom and an air compression pump at the top are used to deploy an air compression unit array (1). The hollow buoys (10) are pushed upwards by waves, thereby directly driving air compression pump pistons (8) to move upwards to compress air, which is then stored in a high-pressure air storage tank (2). The high-pressure air in the high-pressure air storage tank (2) pushes an adapted gas turbine (3) to operate, which in turn drives an adapted power generator (4) to generate power. The power generation system solves the problem of harvesting and stably outputting wave energy, and has the advantages of high energy harvesting efficiency, stable power generation, high conversion efficiency, and environmental sustainability, thereby providing an innovative and efficient solution to wave-energy power generation.
