Seaturns' wave energy device deployed near Brest
Vincent Tournerie, Founding President of Seaturns, stated: “This support is crucial to deploy our full-scale demonstrator from the summer of 2025 and accelerate our industrial development.” The funds will facilitate the installation of a full-scale wave energy demonstrator at the SEM-REV test site off Le Croisic, operated by the OPEN-C Foundation, and advance industrial production and global market expansion.
The announcement follows 18 months of successful sea trials at Ifremer’s test site in Brest, concluding in February 2025. These tests confirmed the durability and efficiency of Seaturns’ wave energy converter, highlighting its potential to generate low-carbon electricity for Europe and beyond.
Seaturns’ technology captures ocean wave motion to produce power. Its cylindrical device, secured by a patented anchoring system, transforms horizontal wave movement into a pitching motion. Inside, a water pendulum and air chambers generate airflow, driving a turbine connected to a generator for electricity production. The design prioritizes cost efficiency, simplified installation, low maintenance, and minimal environmental impact, aiming to lower costs compared to other wave energy systems.
The SEM-REV site, equipped with subsea infrastructure and environmental monitoring tools, supports Seaturns’ efforts to validate system performance and reduce risks before commercialization. In June 2025, Seaturns signed an agreement with the OPEN-C Foundation to deploy the full-scale demonstrator, scheduled for summer 2025, as part of the SEAWEC program to prepare the technology for industrial use.
Launched in April 2025, the fundraising campaign built on years of research and testing, positioning Seaturns to scale its technology. The company plans to deploy commercial wave energy farms starting in 2026, contributing to sustainable energy solutions worldwide.
