CorPower Ocean, a Swedish wave energy developer, due to install a half scale prototype wave energy converter system at EMEC’s scale test site in Scapa Flow in 2018.CorPower follows a structured five-stage verification process established as best practices for ocean energy technology by ETIP Ocean and Wave Energy Scotland. It 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 WECs in increasing scales up to array demonstration in Stage 5. The current Stage 3 program follows the prior testing of multiple prototypes in smaller scales performed in Portugal, France and Sweden since 2013.  CorPower Ocean has taken a large scale WEC through structured verification by dry testing it in a rig in Stockholm, which will be followed by ocean deployment at the European Marine Energy Centre’s (EMEC’s) Scapa Flow test site in Orkney (Scotland). Stage 3 demonstration is supported by best practice from EMEC in Orkney, alongside the experience from offshore power generation company Iberdrola Engineering and EDP, the University of Edinburgh and WavEC Offshore Renewables’ expertise in cost and performance modelling.

€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.

The deployment is being supported by the Interreg NWE FORESEA project, which enables free access to EMEC’s test facilities.

Hi-Drive

As part of the Hi-Drive project, funded by Wave Energy Scotland’s PTO systems call, CorPower’s technology is being 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 will involve a five-month programme of cyclical dry and wet testing of the system in Orkney, culminating in a performance assessment by EMEC. Prior to arriving in Orkney, the PTO will undergo a five-month dry test period in Stockholm using the same test rig, thereby significantly de-risking the ocean deployment.

This novel approach to PTO development will incorporate the installation of a bespoke dry test rig at EMEC for hardware-in-the-loop testing. The test rig will have the ability to subject wave devices to the full range of wave loads corresponding to the most challenging sea states.


 

Waveboost

CorPower are also 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 Converter 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).
