Tidal Harness has successfully tested its 5kW scaled turbine in Southampton waters in a proof-of-concept project funded by Innovate UK under its SMART programme. The completion of these sea trials paves the way for scaling up the turbines.

Another Catalyst graduate, Tidal Harness builds disruptive, single moving part turbines for harnessing energy from tidal currents. The heart of the innovation is its submersible generator which does not make use of any rare-earth magnets and this simplicity delivers cost reductions and greater reliability. The ultimate goal is to drive the cost of tidal energy down to a level that is at least as competitive as offshore wind.
