Bombora’s 60MW Wave Farm (mWave) Feasibility Study

Study investigates the economics of a potential 60MW wave farm
consisting of 40 Bombora Wave Energy Converters at a site near
Peniche in Portugal
Two challenges:
Delivering cost effective energy
Surviving harsh storms
Study demonstrates that mWave technology is commercially viable at scale, validating Bombora’s commercial potential
The review was commissioned by the Australian Renewable Energy Agency (ARENA) and independently reviewed by BMT WBM.

Power Buoy

Between surface buoy and metal plate is a large hydraulic cylinder with a piston inside
As the buoy rises and falls, it pushes and pulls on the piston
This forces hydraulic fluid through a hydraulic motor, which in turn runs an electrical generator
