CorPower Ocean, a Swedish wave energy developer, following a structured five-stage verification process established as best practice for ocean energy technology by ETIP Ocean and Wave Energy Scotland.

The process involves step-wise validation of survivability, performance, reliability and economics starting with small scale prototypes in Stage 1, continued by sub-system testing and then fully integrated wave energy converters (WECs) in increasing scales up to array demonstration in Stage 5.

Since 2013, CorPower have tested multiple small scale prototypes in Portugal, France and Sweden.

CorPower’s technology has been taken through a programme of structured verification guided by best practice support from EMEC, alongside the experience from offshore power generation company Iberdrola Engineering, the University of Edinburgh, and WavEC Offshore Renewables’ expertise in cost and performance modelling.

The project involved a rigorous 18-month test programme, beginning with onshore power take-off tests in Sweden using a bespoke hardware-in-the-loop test rig (enabling CorPower to test a full range of wave loads), and culminating with ocean testing at EMEC’s scale test site at Scapa Flow in Orkney in 2018.

EMEC oversaw the dry and wet testing of the machine, ensuring strict quality management and quality assurance of the verification process and provided Performance Statements for both stages.

€6.5 million has been invested in the Stage 3 program by InnoEnergy, the Swedish Energy Agency and Wave Energy Scotland, with another €4 million contributed by the European Commission’s H2020 WaveBoost project to further develop the PTO.

The deployment of CorPower’s C3 WEC at EMEC was also supported by the Interreg NWE FORESEA project, which enables free access to EMEC’s test facilities.

Waveboost

CorPower are leading the WaveBoost project – a three-year Horizon 2020 funded project aiming to instigate a step-change improvement to reliability and performance of wave energy converters through the development and validation of innovative Power Take-Off (PTO) technology.

The project will demonstrate innovative end-stop and power smoothing technology expected to further improve the survivability and reliability of resonant wave energy converters.

WaveBoost project partners include: CorPower, EMEC, EDP Innovação SA, PMC Cylinders, GS Hydro, The University of Edinburgh, WavEC Offshore Renewables, and The Research Institute of Sweden (RISE).
