WaveRoller is an oscillating wave surge converter that turns ocean waves into constant, renewable energy.
A submerged oscillating wave surge converter generates steady renewable energy from ocean waves. The panel, power take-off, and foundation are the three basic subsystems of the device. Panel collects energy from the waves as it goes through the water. The panel is linked to the mechanical powertrain, which causes hydraulic fluids to be pushed inside a closed hydraulic circuit. All hydraulic circuit elements are contained within a hermetic construction within the device and are not exposed to the maritime environment. The high-pressure fluids are routed through a power storage and smoothing system, which is linked to a hydraulic motor, which drives an electrical generator. This sustainable wave energy power plant’s electrical output is subsequently linked to the electric grid through a subsea cable and landside substation. The device’s foundation is a floating concrete barge that will be dragged from the harbor to the installation location by a tug boat.
Positive facts about WaveRoller
A single WaveRoller unit (one panel and PTO combination) is rated at between 350kW and 1000kW
WaveRoller can support grid stability through fast frequency response (2s-10s)
Life-cycle carbon intensity of the WaveRoller is 33 gCO2/kWh (around 30% lower than solar PV)
Carbon intensity of power generation can be up to 85% lower than existing levels
Current LCOE in the range of 100-150 EUR/MWh, with further reductions possible as deployments increase
Wave energy allows production of renewable electricity using a stable resource freely available to many countries
Offsets reliance on carbon-based generation, so no ongoing costs for fuel (e.g. coal, oil, gas) purchases to generate electricity
