Bombora Floating 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. In deep waters, mWave can be deployed, to exploit a much bigger floating platform opportunity, to deliver utility scale offshore wave projects. The application of mWave to a floating platform provides a potential solution to existing offshore Oil and Gas operations looking to electrify platforms. Bomboras Floating mWave platform can produce up to 4 MW and operate in depths greater the 50 m.
