Minesto’s Deep Green technology generates electricity from low-flow tidal streams and ocean currents by a unique and patented principle similar to a stunt kite flying in the wind.
The wing uses the hydrodynamic lift force created by the underwater current to move the kite. With onboard control system and rudders, the kite is autonomously steered in a pre-determined figure of eight, pushing the turbine through the water. By doing so, the turbine experiences a water flow several times higher than the actual stream speed.
The turbine diffuse power to the generator which outputs electricity via power cable in the tether. Seabed umbilical transfers the electricity to the onshore connection.
The wing will be made from composite material, with inner beams in carbon fibre and an outer shell in fiberglass. On the inside it is filled with a foam with room for dry ballast and an adjustable dynamic buoyancy system. On the outside, the wing is fitted with sensors to measure current velocity, kite speed and level of depth.
