New Technologies for wave energy farms

The European Research Project COIN is coordinated by Technische Universität Braunschweig

Ocean energy, and wave energy, in particular, can contribute to achieving EUs renewable energy targets by diversifying the exploitable marine renewable energy sources. However, ocean energy is relatively far from commercial operation, facing techno-economic challenges both during device/component design (strategic stage) as well as concerning monitoring, control, and maintenance (operational stage). The COIN project aims to provide solutions to challenges in both stages. In particular, COIN provides three control-oriented innovations:
(1) Innovative connector (mooring and electrical) to subsea infrastructure, enabling (active) peak load limiting and damage prevention, developed based on control co-design. Considering relevant control action in the design loop, secures optimal performance;
(2) Innovative AI-based real-time wave prediction algorithm using hybrid wave sensing techniques, enabling second-by-second (non-linear) prediction as input to control frameworks;
(3) Innovative digital-twin based health monitoring and health-aware control framework, developed to maximise performance while minimising down-time and failure, thereby maximising (remaining) useful life.
Being paired with a holistic techno-economic, multi-level, multi-objective optimisation framework, COINs technology development results in more performant ocean energy technology and, thus, to a more efficient, clean, sustainable, secure and competitive energy supply.
Partners from Germany, Denmark, France, UK, Ireland, Italy, Spain and Portugal build the consortium of the project that is being coordinated by Technische Universität Braunschweig.
