OWCs can be located on the shoreline, near-shore or offshore. Incoming surface waves induce an oscillating flow of air within the chamber which, in turn, flows backwards and forwards through an air turbine installed in a duct connecting the chamber to the atmosphere. The turbine converts this reciprocal air movement into electrical energy.
The challenge of OWC turbine technology is to achieve satisfactory efficiency over a wide operating range. The airflow not only varies between zero and 100 percent, but also changes direction as it reciprocates. At the same time, the shaft rotation must be maintained in one direction (i.e. clockwise rotation).
Siemens patented the HydroAir™ turbine which is able to resolve the challenges present in wave energy conversion while offering outstanding performance and reliability. Constructed to withstand the rigors of a marine environment and ambient conditions, it uses a combination of corrosion-resistant stainless steel, aluminum and reinforced composites which also yield to reduced weight.
HydroAir offers the following benefits when compared to other turbines being used for wave energy capture:
Simply put, the HydroAir product can be installed anywhere in the world including extreme ambient conditions and can serve various markets, including but not limited to, Oil and Gas, Power Generation, Industrial, and Marine.
