Tidal turbines, a sector with promise
Harnessing the strength and speed of marine currents, which are perpetual and predictable, the tidal turbine generates decarbonised and regular energy.
Through its subsidiary OpenHydro, Naval Energies is developing tidal turbines with rotors that are 16 metres in diameter with a nominal power of 2 MW each, mounted on gravity foundations installed directly on the seabed.
As a system-engineering leader and supplier of plug-and-play systems, we manage projects right from the demonstration phase and prepare the ramping up of the power output of pilot farms. Once the technology and economic model have been validated, we prepare the deployment of commercial farms.
Naval Energies, a pioneer for the industrialisation of tidal turbines
We are developing an international portfolio of projects and demonstration prototypes at different stages of development in geographical areas benefitting from very strong tidal currents, such as Canada and Japan. In France, we are actively pursuing the development of the Normandie Hydro pilot farm in Raz Blanchard.
To support its ramping up and satisfy international demand, Naval Energies has built its own tidal-turbine assembly plant, which is the first of its kind in the world. Strategically located in Cherbourg, in 2018 it will start the assembly of a system intended for Japan, then a second for Canada. In 2019, it will start the production of the 7 systems for the Normandy farm, whose installation on the seabed is foreseen for the start of 2020. A tangible sign of Naval Energies’ commitment to tidal turbines, its industrial capacity is scaled to take on an annual production of 25 turbines in the medium term, representing a gross power output of 50 MW per year.
The advantages of our technology
Our turbines offer numerous advantages:
On a market that offers considerable technically-exploitable potential — 100 GW — Naval Energies is scaled to address the challenges of the most innovative projects, thanks to its global presence, its unique know-how and its capacity to establish industrial and commercial partnerships.
We are investing in the regions that are most suited to the development of this technology, such as Northern Europe, Indonesia, Japan and the North Atlantic coast, as well as the United Kingdom – which has the largest technically-exploitable potential in Europe (about 9 GW) – and in France (3 to 5 GW).
