Bombora is meeting energy transition demands with a market disruptive product to deliver continuous, reliable ocean energy for global use in national and island grids.


Scaling up or down is achievable through design simplicity, focused on delivering utility scale power generation capacity.



A modular design approach has been adopted for all key system components, cell module and PTO, to reduce cost and allow for scaleability and ease of maintenance.

This modular approach also achieves greater manufacturing efficiencies. As mWave™ production volumes increase, economies of scale drive down costs.



Submerged with no external moving parts other than the flexible rubber membranes, mWave™ is designed to withstand extreme ocean storm conditions.



Scaling mWave™ to 3MW and 4MW, respectively for bottom-fixed and floating platforms, significantly reduces the equipment CAPEX cost per MW.

Further scaling is expected to lead to additional reductions in the cost of energy, just like larger rotors led to dramatic falls in the wind energy in the cost of energy.

The modular approach to design achieves manufacturing efficiencies. As volumes increase, economies of scale drive down costs.



Patented flexible rubber cell module design. mWave™ has multi megawatt capacity. The unique rubber membrane design is highly responsive to the full range of wave periods and wave heights enabling mWave™ to produce more power in a greater range of sea conditions.


Technical overview

Bombora has developed a patented membrane-style wave energy converter, mWave™. mWave™ is unique among wave energy converters as it simultaneously addresses the cost of energy and ocean wave survivability challenges. This new approach proffers a new era for wave energy.

The Cell Module

mWave™ features 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 maximise 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 . The cells are refilled once the wave has passed. The flexible membrane is made from industrial grade rubber. The longstanding use of similar materials in a range of marine applications has demonstrated the material’s reliability and longevity.

mWave™ has no external parts, other than the flexible rubber membranes. Our robust rubber cell membrane extracts power simply without complex mechanisms greatly reducing maintenance requirements. Our replaceable modular design streamlines maintenance, minimising downtime and maximising power output.

mWave™’s cell modules have the unique ability to shut down in extreme storm events. Limiting the loads reduces capital costs and improves the all important cost of electricity.

The Power Take-off
(PTO Turbine and Generator Module)

The air flow in the duct drives an unidirectional flow turbine which in turns drives a variable-speed generator. This type of turbine and generator are off-the shelf technology, even if adapted for the mWave™ operating envelope.

Electricity from the generator is transferred to the shore via a sub-sea cable. Following a process of power conditioning, the electricity is delivered into the local grid.

All operations and maintenance are achievable using existing service vessels used in both fixed bottom wind and offshore oil and gas industries.

mWave™ can be deployed on different platforms to suit a nearshore or offshore ocean environment. Find out more about Bombora’s Fixed mWave™ , Floating mWave™ and Integrated mWave™ platforms here.
