Seaturns Embarks on Breakthrough Wave Energy Trial in France
French wave energy technology developer Seaturns has kicked off a pioneering full-scale offshore trial of its wave energy demonstrator near the Gironde estuary on the Atlantic coast of France. This initiative represents a significant leap for the company and the broader European energy landscape, as it collaborates with Ireland’s ESB, an established energy firm, to enhance wave energy capacity across the continent.
A New Era for Wave Energy in France
The deployment of Seaturns’ full-scale demonstrator is being heralded as a historic moment for the wave energy sector in France. This launch marks the beginning of a minimum 12-month offshore trial campaign, which is seen as a critical step towards achieving commercial deployment and technology certification by 2027. This trial is designed to validate the technology’s performance and reliability, setting a robust foundation for future developments in wave energy.
Collaboration with ESB
The collaboration with ESB adds a layer of expertise and oversight to the project, providing Seaturns with invaluable insights from one of Europe’s leading energy utilities. As part of this partnership, ESB will monitor key stages of the deployment and the performance of the demonstrator under real operational conditions. This monitoring aims to address fundamental challenges that have historically hindered the commercialization of wave energy, such as storm survivability and structural efficiency.
Vincent Tournerie’s Vision
Vincent Tournerie, Founder and Chairman of Seaturns, emphasized the significance of this deployment, stating, “The installation of this first full-scale demonstrator marks the culmination of more than ten years of research and development.” He explained that the company has followed a meticulous validation program over the years, progressing through multiple testing stages before reaching this pivotal full-scale deployment. This structured and gradual approach assures confidence in the technology’s viability and robustness.
Strategic Location for Testing
The demonstrator, referred to as S1, has been positioned 27.5 kilometers off the Port of Le Verdon in Nouvelle-Aquitaine. This strategic location has been chosen for its representative wave conditions that closely mimic real offshore environments, offering logistical accessibility for marine operations. The trial will be instrumental in validating the floater’s dynamic behavior, refining offshore operational procedures, and collecting essential data for technology certification and eventual commercialization.
Comprehensive Data Collection
Throughout the trial, Seaturns will gather extensive data on turbine output and floater behavior to form the evidential basis for technology certification. An environmental impact monitoring program will also be maintained during this period, ensuring that all operational protocols align with environmental standards. This data-driven approach is fundamental to validate the technology’s performance in real sea conditions.
Milestones Ahead
The results from this trial campaign are anticipated to support technology certification by mid-2027. The insights gleaned will directly influence Seaturns’ roadmap toward industrialization and the commercial rollout of its first 2 MW pilot project in Mauritius. This pilot is being lauded as a world first for the wave energy sector, with future plans for a substantial 10 MW commercial project.
Real-Time Monitoring and Insights
Arthur Chauliac, Trials Manager at Seaturns, detailed the installation process and ongoing monitoring efforts. The fully instrumented floater is subjected to real-time performance tracking, which is correlated with wave conditions measured by a nearby buoy. This extensive data collection will provide robust evidence for the viability of Seaturns’ technology, driving it towards certification and eventual commercialization.
Institutional Support and Market Potential
The partnership with ESB symbolizes a growing institutional interest in wave energy technologies as a viable, bankable renewable energy source. With wave energy resources projected to offer significant power potential along the Atlantic coast of Europe, both Seaturns and ESB are poised to accelerate the development and market adoption of wave energy technologies.
This momentum is further underscored by Seaturns’ plans for a fundraising round in early 2027 to support its growth strategies, including advancing from Technology Readiness Level (TRL) 6 to TRL 8.
The European Wave Energy Landscape
With estimates indicating Europe’s wave energy resources could exceed 400 TWh per year, the region holds a leadership position in wave energy technology development globally. Seaturns’ successful deployment and validation of its technology may position it as one of the first companies globally to achieve technology certification, marking a significant milestone in the global push for renewable energy solutions.
Through these initiatives, Seaturns is not just advancing its corporate objectives but is also contributing to a sustainable energy future, making waves in the renewable energy sector that may reverberate far beyond the shores of France.
