Scarcity of resources, climate change

For our future, let’s turn to the sea


With a technically exploitable potential estimated at several thousand TWh/year, wave energy converters (WECs) have a strong development potential. About 10% of the world's annual electricity demand could be met with wave energy production.

Taking into account the learnings from existing wave technologies and the various barriers to their commercial development, Seaturns has defined five research objectives:
- Minimise the levelized cost of energy (LCOE),
- Ensure a high level of reliability and survivability to withstand severe sea states,
- Efficiently capture different types of swell,
- Facilitate installation and maintenance operations at sea,
- Minimise the cost and frequency of maintenance interventions.

To harness wave energy and convert it into electricity, Seaturns has developed a breakthrough wave energy solution based on an innovative anchoring system. This concept has been patented in France and internationally (Australia, China, Europe, South Africa and USA).

The developed technology is based on the principle of an internal water pendulum oscillating in a cylindrical floater. It is a simple, compact and robust solution, with reasonable dimensions.

Several markets are targeted: grid electricity production, supply to industrial sites and off-grid areas.

Tank tests | Nantes | 2023

In February 2023, Seaturns is conducting two weeks of tests in the wave and ocean engineering basin of the LHEEA Centrale Nantes, the Laboratoire de recherche en Hydrodynamique, Énergétique et Environnement Atmosphérique at École Centrale de Nantes. These tests enable establishing reference power matrices to evaluate energy performance in greater detail, and analysing survival configurations in severe sea states.

These tests were funded by the Nouvelle-Aquitaine region as part of an R&D start-up innovation support contract.

Tank tests | Santander | 2021

In May-June 2021, Seaturns conducts two weeks of tests at Cantabria Coastal and Ocean Basin, the wave basin of IH Cantabria in Spain. These trials enable testing a wave energy converter at a scale of 1:10, which is a great step forward in Seaturns’ R&D programme. At this scale, it is possible to test an energy capture turbine and moorings representative of current practices in the offshore sector.

The access to the basin was funded by the European Union as part of the MaRINET2 programme.

Seaturns closes the first part of its fundraising!
The WiCLUB Économie Bleue is a new financing scheme for innovative projects in the maritime sector, set up by the crowdfunding platform WiSEED, the Pôle Mer Bretagne Atlantique (of which Seaturns is a member) and the Pôle Mer Méditerranée. It has simultaneously financed three projects, including Seaturns. A private investor also participated in this fundraising.
