Marine device passes 200 MWh
Tidal Generation has surpassed the 200 MWh mark of electrical power generated and fed into the national grid with its 500 kW tidal turbine prototype, which operates at the European Marine Energy Centre’s offshore test site off the Orkney Islands, Scotland. The device is installed as part of the Deep-Gen III project co-funded by the Technology Strategy Board.
The unit’s three-bladed turbine is attached by a tripod to the seabed and can operate submerged at water depth of 40 meters. Its innovative design allows the turbine to continually rotate to face the incoming tide at an optimal angle. In addition, the turbine unit is semi-buoyant and can be easily towed to and from the point of operation, minimising installation and maintenance costs, according to Tidal Generation, a wholly owned subsidiary of Rolls-Royce.
The government has launched a £20mn Marine Energy Array Demonstrator scheme (MEAD) to support up to two pre-commercial projects to demonstrate the operation of wave and/or tidal devices in array formation over a period of time. Originally announced last summer, organisations across the UK will now be able to bid for a share of the £20mn, helping to spur on growth in this new sector. Generating energy from the power of waves or tides could provide up to 20% of current UK electricity demand, according to the Department of Energy and Climate Change.
