A half-scale C3 wave energy converter has been installed at the European Marine Energy Centre (EMEC) in Orkney Scotland to help demonstrate its commercial viability.

CorPower’s C3 point absorber was installed at the Scapa Flow scale test site in collaboration with local marine contractor Green Marine (UK) Ltd.

“This demonstration programme shows how our resonant WEC technology can significantly reduce both CAPEX and OPEX of wave energy,” said Patrik Möller, CEO at CorPower Ocean.

“The compact lightweight design enables effective handling using low cost vessels, reducing operational costs.”

Device installation

The device was towed to the EMEC site and the surface operated install sequence was successfully performed from the Green Isle multicat vessel. The C3 WEC was connected to a floating microgrid unit provided by EMEC.

This microgrid has been designed to allow the C3 device to behave as if it were grid connected by providing a stable voltage and frequency reference, simulating the impedance of a typical grid connection, absorbing power from the device under test and providing power to auxiliary systems.

With the C3’s performance having already proven in grid connected configuration during a dry testing campaign in Stockholm, this ocean deployment is looking to prove off-grid operations to address market segments such as islands, offshore installations or remote coastal locations around the world.

CorPower’s product development follows the structured five-stage verification process of Wave Energy Scotland (WES) and ETIP Ocean involving step-wise validation of survivability, performance, reliability and economics.

The Stage 3 demonstration is funded by WES, the Swedish Energy Agency and InnoEnergy, with the testing at EMEC also supported by Interreg NWE FORESEA project.
