Eco Wave Power: Floaters Produce Clean Electricity From Ocean Waves
This is the Eco Wave Power, a cost-effective, low-maintenance, and state-of-the-art technology that produces clean, renewable electricity from ocean waves. Simple yet cleverly designed, the Eco Wave’s floaters can be attached to existing man-made structures, such as docks. This setup makes the floaters accessible and simplifies the installation process and maintenance. With 1 billion people reportedly lacking access to electricity and almost half of the world’s population living near the coastline, Eco Wave Power wants to fill a void with a different approach than solar and wind energy.
Eco Wave’s floaters draw energy from incoming waves by converting the rising/falling motion of the waves into a clean energy generation process. The movement of the floaters compresses and decompresses hydraulic pistons, which transmit bio-degradable hydraulic fluid into land-located accumulators. This results in high pressure being built in the accumulators, which rotates a hydraulic motor and a generator, and then electricity is transferred into the grid through an inverter. After decompression, the fluid flows back into the hydraulic fluid tank, where it is re-used by the pistons.
Electricity is produced starting at wave heights of 0.5 meters. When the waves are too high, the floaters will automatically lift above the water level and remain in an upward position. When the storm passes, it resumes operation.
The EcoWave operates best on-shore/nearshore. Wave energy developers who opt to have their systems off-shore often encounter problems commercializing. These high costs from off-shore deployment include the use of ships, divers, and underwater electrical transmission cables, and underwater mooring. Also, off-shore climates are too harsh, which is hard for stationary man-made machinery to survive. These high operation costs, risks, and low reliability make it harder to get insurance. Additionally, offshore wave energy systems aren’t considered environmentally friendly as they require mooring to the ocean floor, which disturbs local marine habitats and could hinder marine migration.
Currently, the Eco Wave Power technology is being implemented in Israel and Gibraltar, where the company is the trailblazer in this type of renewable energy. It’s operating “the only grid-connected wave energy array in the world, which is operated under a PPA (Power Purchase Agreement).”
