Developer for SkySails Power, a kite-based wind generator system, says it consists of five main components: a free flying kite with rope, a launch and recosystem, an automated control system, a generator for producing electrical power and a support platform.
SkySails Power operates at altitudes between 200 and 800m. It can be installed on conventional offshore foundations and on floating platforms. That way the SkySails Power system can also be secured quickly and easily at water depths of down to 700 meters using traditional anchoring technologies and readily available offshore support vessels.
Energy is generated as the wind pulls the rope from a drum connected to a generator. A return phase begins once the rope extendes to its maximum length.
The kite is then flown in a position with a low pull force. This is when the generator acts as a motor and reels in the rope until its extended length is short enough for the next energy-generation phase. This action consumes only a fraction of the power generated during the power phase. The residual energy is fed into the electrical power grid.
SkySails Power also works onshore. Mobile units can be used as stand-alone generators to provide electricity, or fresh water through seawater desalination, or both. This patented towing kite for cargo ships has been proven in the tough day-to-day use on board seagoing vessels. In good wind conditions, it can replace up to 2 MW from the main engine, which saves ships up to 10 tons of fuel oil a day.
SkySails is the only company in the world that now offers industrial products for using abundant high-altitude winds. The generator also benefits from the company’s broad and global patent portfolio that includes some 300 patents issued or applied for, in 16 patent families.
