Tidal energy is a new realm of renewable energy. As technology advances, GL Renewables Certification (GLRC) is contributing its expertise by certifying Alstom’s tidal turbine prototype. Certification of tidal turbines is one of the key development areas for the tidal industry in the future, and represents a major milestone for Alstom on the REDAPT project. GL RC and Tidal Generation Limited (TGL, now rebranded Alstom) have worked closely together to achieve ‘C-Design Assessment’ certification for Alstom’s full-scale 1MW tidal turbine. “The certification was carried out according to our Guideline for the Certification of Ocean Energy Converters,” said Andreas Schroeter, Managing Director GL Renewables Certification.

The sale is expected to complete within the next few months, subject to closing conditions. About Tidal Generation Ltd. 1.    Rolls-Royce will sell TGL to Alstom UK Holdings Ltd, a wholly owned subsidiary of Alstom. 2.    TGL is a wholly owned subsidiary of Rolls-Royce Holdings plc that is managed and reported in the Energy business segment. 3.    In September 2010 TGL’s 500kWe tidal stream turbine concept demonstrator unit was deployed at the European Marine Energy Centre’s (EMEC) offshore test site, off the Orkney Islands in Scotland, and generated over 200 megawatt hours of electricity supply to the grid. It was the first EMEC located project to receive Renewable Obligation Certificates.

Rolls-Royce is continuing to invest in renewable energy sources by taking a 23.5 per cent equity stake in TGL, a privately-owned company developing free stream tidal power generation capability. Rolls-Royce is researching key technologies to provide solutions to the environmental challenges in aerospace, marine and energy markets in order to bring innovative products to market. It sees considerable synergies between the technologies and skills in its existing marine and energy businesses, and will apply these to TGL’s tidal power concept. TGL, in which Rolls-Royce has already invested £1.5 million and technical resource, is developing 500kW and 1MW demonstrators to assess viability ahead of the development of commercial multi-unit systems for tidal power arrays.
