WaveRoller - A renewable wave energy power plant in near-shore areas

WaveRoller provides a reliable, stable and predictable source of renewable energy that compliments more intermittent technologies.

WaveRoller taps the unused ocean energy resource that is readily available for many locations where other renewable energy sources cannot be fully used. The machine operates in near-shore areas (approximately 0.3-2 kms from the shore) at depths of between 8 and 20 meters. Depending on tidal conditions it is mostly or fully submerged and anchored to the seabed. As the WaveRoller panel moves and absorbs energy from ocean waves, a hydraulic piston attached to the panel pumps hydraulic fluids inside a closed hydraulic circuit. All the elements of the hydraulic circuit are enclosed inside a hermetic structure within the device and are not exposed to the marine environment. Consequently, there is no risk of leakage into the ocean. The high-pressure fluids are fed into a power storage and smoothing system, which connects to a hydraulic motor that drives an electricity generator. The electrical output from this renewable wave energy power plant is then connected to the electric grid via a subsea cable. The technology can be deployed as single units or in farms.
