“We warmly thank the 1,543 investors who have placed their trust in us. This support is crucial for deploying our full-scale demonstrator and accelerating our industrial development," said Vincent Tournerie, Founder and President of Seaturns.

“I invested in Seaturns because we are developing a high-potential emerging technology for Europe’s energy mix. We are providing a concrete solution to decarbonization challenges and actively preparing for industrial scale-up," commented Lawrence Sigaud, Deputy CEO of Seaturns.

Designed to meet the challenges of the energy transition, the Seaturns solution features an optimized design for seamless marine integration and increased resilience to extreme conditions. Manufacturing is optimized to reduce costs and prepare for mass production, while installation is simplified to enable rapid deployment of future wave farms worldwide.

A ¼-scale prototype was tested for 18 months at Ifremer in Brest, until February 2025, validating the robustness and efficiency of the concept and paving the way for its industrialization.

The funds raised will be allocated to three strategic areas:

  • Finalizing R&D with the full-scale demonstrator to be deployed in summer 2025 at the Sem-Rev site,
  • Launching industrialization,
  • Accelerating international commercialization. 

Since its founding, Seaturns has benefited from the support of numerous public and institutional stakeholders: Bpifrance, the European Union through Horizon Europe, the French government via the i-Nov innovation contest, the Nouvelle-Aquitaine Region, Ifremer, and the Open-C foundation, operators of offshore test sites.

Founded in 2015 in Bordeaux by Vincent Tournerie, Seaturns designs patented wave energy technology that combines performance, operational simplicity, and controlled costs. Following the successful testing of its ¼-scale prototype at Ifremer – Brest, the company is now preparing to take a major step forward with its full-scale demonstrator, aiming to offer a clean, predictable, and decentralized source of electricity aligned with carbon neutrality goals.
