This programme is for the research and development of Power Take Off (PTO) technology, a fundamental component of a wave energy converter. The key task of the PTO is to transform the motion from the prime mover, as it reacts with itself or a fixed reaction point, and convert it into a smooth electrical output ready for delivery to the grid.
17 projects started within this programme in 2015 at three different stages.
