Naval Energies exits tidal turbine market, concentrates on other technologies

3 August 2018

Naval Energies has announced it has decided to stop investing in the field of tidal turbines, and instead will now concentrate its efforts on floating wind turbines and Marine Thermal Energy Conversion.

Naval Energies is currently the only player in the marine renewable energies to have developed three product lines: tidal turbines, with its Irish subsidiary OpenHydro, floating wind turbines, and ocean thermal energy conversion.

Naval Energies has developed the technology of tidal-turbine energy to the industrial launch stage. On 24 July, the company deployed a new tidal turbine in Canada and connected it to the power grid. For the second time in two years, a 2MW turbine was installed in the Bay of Fundy.

IN a statement however it said that the market for tidal-turbine energy is closing. The French Environment and Energy Management Agency (ADEME), as part of a public debate on the Multi-annual Energy Plan for France, only foresees 100 to 150MW to be installed between now and 2028, i.e. 50 turbines of 2MW each over ten years. The UK also decided two years ago not to launch specific tenders, and tidal has now to compete with more mature fixed bottom offshore wind. In Canada, there is also great sensitivity to the cost of the technology.

This gap between the technology and the demand on the market, and the lack of commercial prospects over the long term, are forcing Naval Energies to bring its developments in tidal energy to an end, it said. Following in-depth discussions with public and private stakeholders as well as with the French Environment and Energy Management Agency (the ADEME), Naval Energies decided to stop its investment in tidal energy.

 “It is with regret, but also responsibility, that we are taking the decision to stop developing tidal-turbine energy,” said Laurent Schneider-Maunoury, CEO of Naval Energies.  “The deterioration of the market, in France and around the world throughout the recent months, has been reflected in a lack of commercial prospects over the long term. This evolution means that we alone can no longer finance the development of the tidal-turbine activity.

“In the future, Naval Energies will focus its development on Floating Offshore Wind (FOW) and Ocean Thermal Energy Conversion (OTEC), which are receiving support from the public authorities.”
