Aaron Larson of Power writes about a fish-friendly hydro turbine.
- While a renewable source of energy, hydropower can have negative impacts on fish populations.
- Alameda, California-based Natel Energy has developed a hydropower turbine that reduces fish fatalities in rivers.
- The company has three pilot projects operating and all have shown that its systems allows fish to pass through with more than 95% efficiency.
- This innovation will allow clean energy to generate and fish habitats to thrive.
“The RHT is optimized for low head (from 2 meters to 20 meters) and doesn’t require fine fish screens. The design’s thick, slanted blades transport fish away from the leading edge into wide inter-blade regions and downstream to the outlet. The progressive slant of the blades from hub to tip also minimizes the likelihood of severe strike and eliminates the risk of entrapment between moving and stationary parts.”
