meters, the autopilot steers the kite into a neutral position with minimal drag and lift. While consuming only a fraction of the energy generated before, the generator now acts as a motor and reels-in the tether. The system continuously repeats this process, flying the kite at an altitude of 200 to 400 meters. Energy generated by the
Airborne Wind Energy System can be fed into the grid, stored in batteries, or directly consumed.

Leibniz
Universität Hannover. From the operation of the airborne wind energy system, the consortium intends to gain knowledge for the further development and scaling of airborne wind energy systems as well as on environmental influences, safety aspects and licensing requirements. This includes, for example, expert opinions on noise emissions, avifauna and air traffic safety.

The airborne wind energy unit in
Schleswig-Holstein was built as part of the joint research project "SkyPower100", funded by the German Federal Ministry for Economic Affairs and Energy and involving SkySails Power GmbH, EnBW Energie Baden-Württemberg AG, Omexom Renewable Energies Offshore GmbH and

In the weak economy of 2012, a time of low investment by shipping companies, the company laid off half of its 80 employees. On March 7, 2016, SkySails GmbH, as part of the SkySails Group, was forced to file for insolvency and was dissolved on April 5, 2016. Since then, SkySails Group GmbH, as the

Driven by the wind, the automatically controlled power kite rises in figures of eight. As it gains altitude, it unwinds a tether from a winch on the ground. The tractive force drives a generator inside the winch that produces electricity. Once the tether has reached its maximum extension of 800

There's a structural problem slowing down the process: ship owners (who have to make the investment) often don't pay for the fuel – that's the charterer's duty. The charterer on the other side doesn't charter the ship for long enough a period to make low-carbon technologies pay

was the first ship to be built to use the system, and the first using a production model. The 132 m, 10,000 tonne vessel was fitted with a 160-square-metre (1,700 sq ft) kite and launched 17 December 2007 and departed the northern German port of

The ship completed its journey on 13 March 2008 after sailing from
Germany to Venezuela, then to the United States, and ultimately arriving in Norway. While the kite was in use, the ship saved an estimated 10-15% fuel, $ 1,000 to $ 1,500 per day.
