Fish Friendly Free Flow Turbine

Innovative turbine system with uniquely high efficiency

  • World Alliance Member
  • Featured Solution
  • Labelled Solution
Label Date May 7, 2021
From Netherlands
Maturity stage TRL 7 - Prototype testing in the real world

FishFlow Innovations developed an innovative and patented design that also makes the turbine fish-friendly and silent. The turbine can withstand the incredible forces occurring at open sea. The revolutionary design saves on construction costs which makes it possible to generate electrical energy at a very competitive price per kWh. The impeller of the FishFlow Innovations Free Flow Turbine is bi-directional; it generates power when rotating clockwise as well as when rotating counter-clockwise. This means it generates electrical energy during ebb and flow when in use as a tidal turbine. The unique and patented shape of the impeller doesn’t only make the turbine fish-friendly but also makes it highly efficient. The specific shape of the impeller blades do not induce cavitation and the water leaving the impeller is released in an almost straight beam.

The Environmental Benefits

  • 2.1 GWh/yr yield with ø 8m turbine at 2 m/s water velocity
  • 50 years life time expectancy
  • 100% fish friendly hydropower generating clean energy
  • 95% Recyclable

The Financial Benefits

  • Less than 10 years payback time
  • At least 15% more energy yield than mainstream alternative
