CorPower Ocean's EIC Accelerator Packages Waves Into Farms

Wave energy's problem has never been the energy, it has been survival. The sea that delivers the power also destroys the machine, which is why decades of wave projects ended as wreckage. CorPower Ocean's converter is built the other way round: the buoy is pulled down by pre-tension and pushed up by the wave, with stored pneumatic pressure providing the restoring force, which the company compares to the pumping of the human heart. In normal seas a phase control system times the buoy's oscillation to each wave, which it says multiplies energy capture fivefold per amount of equipment; in storms the buoy becomes transparent to the waves.

The EIC Accelerator selected the project, CORPACK, at its October 2024 cut-off for blended finance under the renewable energy challenge, and CORDIS records a grant of €2,499,999 from July 2025 to June 2027. The project is not about the machine but about the product around it: standardised CorPack clusters of 10 to 30MW, placed side by side to build farms of hundreds of megawatts, with the company becoming a turnkey supplier and reaching final investment decision on its first farms, aiming at 600MW installed by 2032.

Power on the grid, in the Atlantic, now

CorPower's claim to be past the prototype stage is specific: its utility-scale technology is operating off northern Portugal, delivering electricity to the grid, having withstood storms with waves up to 18 metres, with independent verification of performance in the actual operating environment. The 2025 annual report, published in May 2026, says the C4 is still being refined at the Aguçadoura site, that Stage 5 of a structured verification programme is complete, and that the next-generation C5 has finished design and entered manufacturing, with commercialisation targeted for 2027.

The annual report's account differs from the website, which says "this isn't a prototype, it's commercially ready technology generating power today" while the report describes the current machine as being refined and the commercial one as being built.

Why the grant is about packaging

The EIC project tackles the part of wave energy that is not physics. A single converter, however good, cannot be financed; a utility needs a product with a known cost, a known output and a maintenance model. The CorPack is CorPower's answer: identical units manufactured in volume, grouped into clusters of 10 to 30MW that keep producing while individual units are serviced, deployable without specialised port infrastructure and able to share electrical and transmission infrastructure with offshore wind.

The project's framing of the opportunity is large: global electricity demand doubling by 2050 with 90% expected from renewables, 60% of generation still fossil today, and wave energy capable of supplying 10% of world electricity demand. The company adds a system argument backed by a case study, that adding 54MW of wave capacity at a Spanish data centre removed the need for 301MW of wind overbuilding and saved €15 million a year.

Four EU instruments and a €53 million round

CorPower is the most heavily EU-funded company in this cut-off. Its 2025 report lists €40 million from the EU Innovation Fund for VianaWave, a pre-commercial wave park off Viana do Castelo, €30 million from Horizon Europe for the CorPower-led Power Farm EU consortium, €17.5 million from the EIC for its original equipment manufacturing business, of which the €2.5 million CORPACK grant is the recorded non-dilutive part, and a B round closed at €53 million with new strategic investors Acario Innovation, the venture arm of Tokyo Gas, and GTT Strategic Ventures. Earlier, a €32 million Series B1 in October 2024 led by NordicNinja, SEB Greentech and EIT InnoEnergy took total funding to about €95 million.

The renewable Europe has not tried yet

Wave power's argument is complementarity rather than cost: it produces when wind drops and after sunset, so it reduces the overbuilding and storage that a wind and solar grid needs. For the Atlantic coast, from Portugal to Ireland, it is also a local resource next to the load. That is why the EU has put Innovation Fund, Horizon Europe and EIC money into the same company, and why the Portuguese test site matters beyond engineering: if the first farms are financed there, Europe gets a supply chain for a technology nobody else has commercialised.
