How are Oscillating Water Columns Improving?
Oscillating water columns (OWCs) function by using an air chamber within a structure that is open to the sea. As waves enter and exit the chamber, they compress and depressurize the air, driving a turbine. The advancements in OWC technology include:
- Efficient Air Turbines: The development of more efficient and reliable air turbines is making OWC systems more commercially attractive.
- Structural Enhancements: New structural designs that are more durable and require less maintenance have helped to reduce operational costs.
