With the help of DKK 2.7m of EU support funding, a group of Danish project partners are undertaking a 2 year project to develop vertical axis wind turbines in three different sizes, reports professional journal Ingeniøren (The Engineer).
Vertical axis wind turbines have the advantage of making less noise, which makes them more attractive for local deployment in closer proximity to places where people live and work. The target groups for the wind turbines from Windpowertree, as the Danish project team have called their development company, are farms, institutions and companies.
The three planned turbines are a 3 kW model to be tested and type-approved this year, and prototypes of a 4.5 kW and 9 kW turbine to be tested and type-approved in 2011. The wind turbines will be up to 20 metres in height and are designed to stand on open land where there is less wind turbulence than in built-up areas.
Windpowertree's 3 kW model will be tested in the wind tunnel facilities of Danish roof window manufacturer Velux, and when the prototype is ready it will be sent for an accelerated test in the Faroe Islands to see how it stands up to the stormy and icy conditions of winter.
Thorough testing and documentation of performance is a key aspect of Windpowertree's development strategy. According to the company, there are not that many producers of smaller wind turbines who rigorously document that their products deliver the performance they promise, and so Windpowertree sees its thorough documentation as an opportunity to differentiate itself in the market.
