Rolls-Royce prototype tidal turbine off Scotland generates power
Rolls-Royce has confirmed that its prototype tidal turbine, located subsea off the Orkney Islands, Scotland, has generated and fed over 100MWh of electricity into the national grid.
The 500kW turbine prototype was designed and built by Tidal Generation, a wholly owned subsidiary of Rolls-Royce.
The prototype unit is currently deployed at the European Marine Energy Centre's (EMEC's) test site off Scotland.
The turbine was installed as part of the Deep-Gen III project, co-funded by the UK government-backed Technology Strategy Board.
The three-bladed turbine is attached by a tripod to the seabed and can operate, fully submerged at water depth of 40m.
The turbine unit is also semi-buoyant and can be towed to and from the point of operation, Rolls-Royce said.
Rolls-Royce is now building a 1MW tidal turbine demonstration unit as part of the Energy Technologies Institute funded Reliable Data Acquisition Platform for Tidal consortium project, and this unit will be deployed in mid-2012 at EMEC in Orkney.
