Wave Hub is the name of one of the world’s biggest wave energy generation test site. It has been installed off Cornwall’s northern coast and is the UK’s first offshore wave energy site. Wave Hub will allow four wave energy generator systems to be evaluated simultaneously. The systems also have a total capacity of 20 MW.
The project which has been valued at a price of about $64 million, is composed of a sub-station at Hayle in Cornwall, from which a cable has now been mounted under the sand dunes and across the sea bed to the wave generation area 16 km offshore, where the energy generators will be placed. There are four tail cables that can be connected to a different wave energy conversion device.
To keep the undersea cables fixed, about 80,000 tonnes of rock have been placed over them. Ocean Power Technologies Limited (OPT) will be the first wave generator developer connecting its PowerBuoy wave energy converter to one of the tail berths by the end of next year.
According to the minister for energy and climate change Lord Hunt, the UK’s south west is a perfect location for the Wave Hub because it is the country’s first low-carbon economic area.
