RWE Innogy, the renewable division of the German group, has taken a minority stake in Quiet Revolution which manufactures the six kilowatt QR5, a five meter high, vertical axis wind turbine targeted for use in built up areas.
This is the latest investment by RWE Innogy which is planning to invest £40million a year in young technology firms developing and developing opportunities within the wind power market will be a vital part of its strategy.
Prof Fritz Vahrenholt, Chief Executive Officer at RWE Innogy, said: 'The local supply of electric power to individual buildings from renewable energy will become increasingly significant.
“Small wind power units on roofs can make a major contribution to this goal, especially in places with insufficient sunshine, so that photovoltaics would not be efficient enough.'
Small scale wind turbines have come under fire after research carried out by the Carbon Trustindicated they were unsuitable for many urban locations.
But, RWE is hopeful the products being produced by Quiet Revolution will respond to this challenge by continuing to generate energy event in turbulent conditions within built-up areas.
Crispin Leick, from RWE’s Ventures Division, said: 'The purpose of our involvement is to take this promising technology towards mass production, so that it will become commercially usable.'
Robert Webb, Chief Executive Officer and co-founder of Quiet Revolution says: 'We are delighted to be working with RWE Innogy to deliver efficient local wind energy. This investment will allow us to rapidly expand our production capacity to meet demand, and develop a range of new products to satisfy needs in a global marketplace.”
