CCell Mark 3 – Novel Curved WEC Optimisation
University of Bath, Kelvin Hydrodynamics Laboratory
CCell is an oscillating wave surge converter (OWSC) designed to maximise the energy extracted from ocean waves through curvature of the paddle. Laboratory tests of the CCell paddle and its control system have demonstrated a four-fold increase in performance-to-cost ratio compared to other flap-based WECs.
The curved structure not only improves the hydrodynamic performance, extracting more energy from each wave, but it also provides additional strength that reduces the amount of material needed to construction the paddle.
