The Netherlands employs coastal flood control structures that could also be used to harness tidal power. Strict national and European regulations drive new turbine designs that are inherently safe for fish passage. To develop such a rotor design for client Water2Energy, Physixfactor used simulation to adapt a Darrieus wind turbine for water use. Compared to conventional hydropower turbines, experiments show that the Water2Energy vertical-axis design reduces fish mortality rates from 20% to less than 1%.
