News: Rotherham company waved ahead by government


Secretary of State for Energy, John Hutton, is set to grant planning permission for a prototype tidal stream generator to be tested in the Humber Estuary near Grimsby. Pulse Tidal based at the Advanced Manufacturing Park in Rotherham have developed the prototype pulse generator which is capable of generating up to 0.15MW and will be one of the first tidal power machines to supply the national grid. If it is successful, it will be used to develop larger 1MW units which could be deployed in arrays each generating up to 100MW, enough to power the equivalent of 70,000 homes. The technology works by extracting energy from underwater currents in a manner similar to wind turbines. Energy from tidal flows will power a pair of straight horizontal hydrofoils, 11 metres in length, which will move up and down like a dolphin's tail. John Hutton said: "We will be doubling the support available for those technologies under the Renewables Obligation. This kind of tidal project, if proven, will go some way to helping the UK meet its ambitious targets for clean, green energy. "I wish Pulse Tidal every success in the trials."
