September 3 (Renewables Now) - South Wales-based Marine Power Systems Ltd (MPS) has concluded the 12-month sea testing programme for the prototype of its WaveSub wave energy generator.

Over the past year, the 1:4 scale device was tested at the marine test site FaBTest in Cornwall, where it proved its functionality across a range of sea states, the company said in a statement. The process included trouble-shooting and maintenance out at sea, and ended with the decommissioning of the test site last month.

“We have demonstrated the fundamental USP’s of WaveSub such as its inherent ease of transportation, deployment and maintenance; we have achieved a high level of technical capability with the remote control, monitoring and communication systems; and importantly we have shown we are able to generate grid compliant electricity from ocean waves,” commented Graham Foster, chief technology officer at MPS.

The company is now able to proceed with the design, manufacture and testing of a full-scale version in the coming months, it added.

MPS has in the meantime achieved positive results in tank scale prototype testing of two floating offshore wind devices called DualSub, which captures both wave and wind energy, and WindSub, which is wind-focused only. The company has now sped up the development of large-scale prototypes of those devices, with the goal of achieving market readiness for all three products in a similar timeframe, it noted.
