One resource Wales has in abundance is the power of waves around our coast. But it isn't, as yet, being exploited.
Now £2m of EU funds has been announced to test a technology to harness energy from ocean waves.
Led by Swansea-based Marine Power Systems (MPS), the £3 million project, which includes a £900,000 investment from MPS, will manufacture and test a 1:4 scale prototype of the WaveSub device.
The device draws upon patented technology developed by MPS which captures the high power density of waves through its power take-off system, and can withstand storm forces.
The £2 million EU funds will allow the prototype to be developed and tested, paving the way for a full-scale device that will be deployed off the Pembrokeshire coast and eventually launched in the commercial market.
