Tidal

The highly scalable turbine is placed inside a 180° rotating turret so it can always face in the optimal direction to the flow, giving up to 30% higher efficiency than any other solution in the market. The turbine is compact due to a generator in the periphery of the runner, avoiding a bulb that constraints the water flow. A speed variable permanent magnet, wet running generator secures reliable and flexible energy generation in combination with high pumping characteristics. In smaller scale, the solution is called Tidal-in-a-box which means utilizing existing infrastructure as dry-docks and port basins by connecting a turbine module to the sluice pipes. Tidetec has verified scalability of the turbines for sizes from 0.5m to 8m in diameter/0,5-25 MW allowing this solution to benefit a wide variety of energy schemes.
