The DNV certification for CorPower Ocean’s C4 device

Swedish company CorPower Ocean has secured a prototype certificate from independent assurance body DNV for its Wave Energy Converter (WEC), a first for the sector. The certification confirms that the CorPower C4 device meets DNV’s stringent requirements for structural strength, reliability and safety under the DNV-SE-0120 standard, following a seven-year verification process that covered design, manufacturing, assembly, dry testing, installation, and performance in extreme ocean conditions.

The device was required to prove it can withstand and operate in storm waves of up to 18.5 metres. By obtaining this certification, CorPower moves its technology from a promising concept to a proven, bankable asset, reducing the technology risk that has long held back investment in wave energy.

CorPower co-founder and CEO Patrik Möller described the milestone as a shift for the entire sector, while DNV Renewables Certification project manager Claudio Bittencourt Ferreira called it “an important stepping stone in the realization of commercial wave energy.”

The announcement comes as the company progresses its first industrial wave farms. In Portugal, the grid-connected HiWave-5 project at Aguçadoura aims to deliver a wave energy solution competitive with wind and solar by 2030, with an expansion to a 10 MW farm. In Scotland, the Valiant project will establish a 5 MW stand-alone wave farm at EMEC’s Billia Croo site, backed by a €19 million EU Horizon Europe grant.

What the DNV stamp means for the bankability of wave energy

The certification that unlocks wave energy finance

Risk perception has been the dominant barrier to commercial-scale wave energy. Without a recognized third-party validation, developers struggled to convince banks and infrastructure funds that arrays could survive harsh marine environments and deliver predictable returns. DNV’s stamp on the CorPower C4 directly tackles that hurdle. By verifying structural integrity, reliability and extreme-weather survivability, the certificate provides the technical de-risking that project finance typically demands.

How CorPower’s projects now become industry test cases

The certificate is not an isolated endorsement; it arrives as CorPower pushes forward with concrete installations. The 5 MW Valiant project in Orkney and the 10 MW Viana Wave expansion in Portugal will be the first wave arrays built against this new benchmark. Their operational data will help validate cost-of-energy projections and, if successful, could trigger a wider pipeline. The EU Horizon Europe grant adds further credibility, signalling public-sector confidence.

The wider competitive landscape

Wave energy remains fragmented, with many developers chasing different device designs. A world-first certification of this kind creates a de facto international benchmark, raising the bar for all. It may accelerate consolidation as other firms seek similar seals, while also making it easier for utilities to compare technologies. The risk is that certification becomes a minimum ticket to the market, squeezing out less mature concepts.

Will wave energy compete with wind and solar?

Even certified, wave energy must reach a levelised cost of electricity competitive with other renewables. CorPower’s target is cost-parity with offshore wind and solar by 2030. Achieving that depends on volume deployment, learning-curve effects and the ability to standardize supply chains. The DNV certificate is a necessary but not sufficient condition; it removes a major capital-raising obstacle, not the economic challenge of scaling up generation.

Implications for wave energy developers and investors

  • For wave energy developers: The DNV framework provides a reference for certification of their own devices, potentially shortening development timelines if they adopt similar engineering and testing standards.
  • For investors and project financiers: The certificate reduces the technology risk wedge in marine energy projects. Funds previously sidelined by the lack of bankability may now reassess wave energy, particularly where government grants or offtake agreements are in place.
  • For the industry supply chain: The move to factory-scale manufacturing of certified devices will put pressure on component suppliers to meet repeatable quality and cost targets. Early engagement with CorPower’s growing demand could become a strategic advantage.
  • Real-world validation milestone: The commissioning of the 5 MW Valiant farm in Scotland, expected in the next few years, will generate the performance data that either solidifies or questions the cost-of-energy forecasts tied to the certification.

Risk & Opportunity Assessment

Commercial RiskMediumDespite certification, wave energy is not yet cost-competitive with wind and solar at utility scale. Commercial viability depends on sustained funding and successful operation of early arrays.
Competitive RiskMediumThe certificate sets a new industry benchmark, potentially lowering entry barriers for other developers who now know what DNV requires, while raising expectations for those without certification.
Regulatory RiskLowCertification is voluntary but may become an informal licensing requirement in some jurisdictions, which would benefit already certified players.
Reputation RiskLowThe certification is a positive reputational signal. Any failure of certified devices in real-world operations would damage both CorPower and DNV’s credibility, but no such event has occurred.
Technology DisruptionLowWave energy technology remains nascent, but the certification does not introduce a disruptive leap; rather it confirms the robustness of a specific design, potentially enabling its wider adoption.
Commercial OpportunityHighBy reducing technology risk, the certification can unlock project finance and government support for CorPower’s wave farms, potentially accelerating the company’s route to revenue and attracting new institutional investors.
