The Advanced Hydraulic-electric PTO (AHPTO) utilises a novel combination of proven, ‘best-in-class’ hydraulic and power electronic subsystems to significantly increase the power capture, reliability, controlability and grid compatibility of WEC prime-movers.

Simple off-shelf industrial hydraulics were employed alongside supercapacitors and full-scale rated converter power electronics to more efficiently convert the WEC power fluctuations into grid-compliant power.
