RWE Renewables GmbH and SkySails Power GmbH have high-flying ambitions. They are planning to fly a 120-sqm kite to a peak of as much as 400 metres above floor to utilise high-altitude winds for producing electrical energy. The two corporations have now entered a collaboration settlement on this pilot mission. RWE is buying an progressive airborne wind power system with an output of as much as 200 kilowatts from the Hamburg-based firm. RWE Renewables will function the SkySails Power system and consider the expertise in the course of the three-year pilot mission. Currently, appropriate areas in Germany are being assessed.
Airborne wind power techniques harness the sturdy and regular winds at heights of a number of hundred metres above floor. Part of the SkySails Power system is a floor station consisting of a winch with an built-in generator. During its ascent in a managed trajectory, the kite pulls rope from the winch – and the built-in generator produces electrical energy from the rotational power.
Once the tether is totally unspooled, the kite is winched again in. It brings itself robotically right into a place of very low resistance in order that it may be hauled again simply. The generator now acts as a motor working the winch. This course of solely requires a fraction of the power that has been generated in the course of the lively part. The cycle can then begin over once more.
Current airborne wind techniques have a most capability of 100 to 200 kilowatts. Developing this expertise additional will enhance the potential output from kilowatts to megawatts and thus make it engaging to be used in giant wind farms. SkySails is already growing such a large-scale system.
“The mild compact design of airborne wind power techniques implies that the impression on individuals and the surroundings is minimal. The techniques work very quietly, virtually don’t have any seen impact on the panorama and barely solid a shadow”, explains Stephan Wrage, CEO of SkySails Power GmbH. He believes that these advantages can additional enhance acceptance for wind power techniques. Stephan Wrage: “This makes our SkySails expertise an thrilling different to conventional renewable wind energy technology.”
