Columbia Power’s StingRAY wave power system is meant to be deployed in water depths over 60m and arrayed in “farms” much like wind turbines. The wave farms are usually located at least 1-2 miles from shore; away from the coastline and the sensitive habitats contained there.
At a high level, the StingRAY captures energy from each passing wave and produces electricity on-board the device. The electricity generation process includes a series of steps starting with the transfer of captured energy from the forward and aft floats to two rotary, low-speed, high-torque electric generators on board the StingRAY. The generated power is then conditioned to stable, electric-grid-compatible output. In a wave farm, this electricity is centrally collected in an offshore “sub-station” for transmission ashore and connection to the grid.
