Swedish marine energy technology firm Minesto has placed an order with German tidal turbine manufacturer Schottel Hydro for a prototype turbine for Deep Green underwater tidal power plant in the UK.

Swedish marine energy technology firm Minesto has placed an order with German tidal turbine manufacturer Schottel Hydro for a prototype turbine for Deep Green underwater tidal power plant in the UK.

Schottel Hydro's turbine is being procured as part of the 10MW Deep Green underwater tidal power plant in the Holyhead Deep seabed area west of Anglesey, Wales.

The order has been placed after completion of detailed design of the turbine and power conversion system by Schottel Hydro for the Deep Green tidal power plant.

Delivery of the turbine will take place in early 2017.

"Compared with the first generation Deep Green, the turbine's performance has been improved by about 10%."

German Schiffbau Versuchsanstalt has also established and verified the prototype design through model tests in Potsdam.

Schottel Hydro technical director Martin Baldus said: "The model scale tests prove the turbines performance and cavitation behaviour to be advantageous compared to previous designs. The integration of our scope of supply into the Minesto kite system works out very well."

The development of the turbine has resulted in a larger rotor diameter with five blades instead of three.

Minesto CEO Martin Edlund said: "Compared with the first generation Deep Green, the turbine's performance has been improved by about 10%."

Minesto will initially install a 500,000kW power plant with subsequent deployments that will increase the capacity to 10MW by 2019.

Edlund further added: "In parallel with the final design we procure subsystems and components, which will be assembled into a first full-scale demonstrator. It will then undergo final functionality testing.

"After that, we are ready to implement Deep Green in full-scale on the offshore facility in Wales during 2017."

The Deep Green marine power plant is designed to generate electricity from low velocity tidal currents.
