A first of its kind, full-scale ‘cell module’ which part of an innovative new marine energy solution being built and tested in Wale was transported from the fabrication workshop of Altrad Services to the assembly workshop at Mainstay Marine Solutions on the weekend, marking a milestone for Bombora’s 1.5MW mWave Pembrokeshire Demonstration Project, which will be installed off the coast of Pembrokeshire in the first half of 2021.
The cell module transported on Sunday is the first of four 15-meter-long, structures that form Bombora’s 75m-long, subsea mWave.
The patented cell module presents a step change from previous approaches to wave energy capture. Each cell module will be covered in a robust rubber membrane. As waves pass over mWave, under-water pressure increases, causing the rubber membranes to compress in sequence, forcing air inside the membranes along a duct and through a turbine spinning a generator converting this rotation into electricity.
mWave’s has a large scale generating capacity which Bombara says sets it apart as an exciting viable alternative to complement existing established forms of renewable energy.
The number of mWave cell module’s can be increased to suit the site location and generate more energy. Bombora’s first grid connected project will have 20 cell modules and generate 3MW.
Bombora moved operations from Australia to Pembroke Dock in 2017 to be part of Wales’ burgeoning marine energy industry. The company is now at the assembly phase of the 1.5MW mWave Pembrokeshire Project supported by a £10.3 million European Regional Development Fund (ERDF) grant through the Welsh Government.
