CorPower has created a Wave Energy Converter (WEC) that unlocks the world’s largest untapped renewable energy source – ocean waves.
Competitive renewable energy production systems are urgently needed. Harvesting nature’s vast resource of energy contained in ocean waves could sustainably and effectively produce 2000-4000TWh of electricity per year – covering 10-20% of worldwide electricity consumption.
CorPower’s Wave Energy Converter (WEC) operates in resonance with incoming waves. It has a heaving buoy on the surface absorbing energy from the combined surge and heave motion of the waves. It is connected to the seabed using a taut mooring line and has a pneumatic pre-tension module between the mooring line and the buoy to enable a lightweight system with good storm survivability.
Lightweight system with high natural frequency of oscillation. - Composite structure provide long lifetime without corrosion issues - Detuned in storms, strongly reducing the loads providing good survivability up to 30m wave. - Power absorption amplified by patented WaveSpring control -
Survivability: naturally transparent to storm waves - Efficiency and high power density: 5x energy output per ton of device compared to previous known solutions - Competitive: low capital and operations costs, high average output - Grid balancing: using the ocean as the most cost effective solar battery on the planet -
