Bombora Bottom Fixed mWave
The mWave is a membrane-style wave energy converter featuring a series of air-inflated rubber membrane covered concave cells mounted to a structure below the ocean’s surface creating an air-filled volume. To maximize energy capture, the structure is arranged at an angle to the incoming waves. As waves pass overhead, air is pushed out of each cell through a series of valves into a one-way air-duct. Air delivery from the membrane pump into the delivery duct is controlled by check valves to create one-way air flow. Air is delivered into a unidirectional flow turbine coupled to a variable-speed generator which produces electricity. Electricity from the generator is transferred to the shore via a sub-sea cable. The air output from the turbine is recycled to reinflate the membrane pumps once the wave has passed. Bombora's fixed bottom mWave can be deployed in 10-25 m water depths and has a 3 MW power rating.
