The Strengths of the Seaturns Solution
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.
Use of Funds
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.
A Strong Support Ecosystem
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.
