CorPower Ocean Receives First DNV Prototype Certificate for Wave Energy Converter

CorPower Ocean reached a notable milestone on October 18, 2026, when it received the world’s first DNV Prototype Certificate for its C4 wave energy converter. This certification, issued under the DNV-SE-0120 standard, confirms the technology meets rigorous requirements for structural integrity, reliability, and safety. The award follows a seven-year independent verification process that examined every stage of development, from design and engineering through to manufacturing, installation, and operational performance. This achievement is a practical step toward establishing wave energy as a bankable and dependable part of the renewable sector.

The path to obtaining the DNV Prototype Certificate started with the creation of a detailed design basis for the CorPower C4. Throughout the multi-year assessment, DNV performed extensive reviews to ensure the converter could handle the harshest ocean environments. Beyond validating the machine's performance, the certification helps lower the perceived technology risk, which is a vital factor in securing project finance, insurance, and institutional investment. This shift helps the wider wave energy industry move more confidently toward commercial-scale deployment.

The CorPower C4 itself features a spherical composite hull that measures 9 meters in diameter and 18 meters in height, with a total mass of about 100 tonnes. The device has been active in the ocean since 2023 and has completed three deployment cycles. During this time, it exported power to the Portuguese national grid and survived storm waves reaching 18.5 meters. Such durability in real-world conditions provides a clear demonstration of the converter's functional capacity and its potential for commercial use.

The impact of this certification reaches beyond CorPower Ocean. By setting a new international benchmark for the industry, it encourages further innovation and technical progress across the sector. The milestone reflects a change in how wave energy is viewed, as it moves from being an experimental concept to a verified technology. As wave power gains recognition alongside established sources like wind and solar, it offers a way to create a more balanced energy mix to help meet global demand.

Looking ahead, CorPower Ocean is focusing on its first two industrial-scale wave farms in Portugal and Scotland. The successful certification of the C4 converter is expected to speed up these projects and drive further improvements in wave energy systems. As the search for clean energy continues, this development highlights the role wave power can play in the broader transition to sustainable energy infrastructure.
