Waves4Power has unveiled plans to provide fossil-free energy supply produced from its wave energy technology for the fish farming industry.

Waves4Power launched the Green Power EcoSystem (GPES) initiative, whose goal is to provide power to the fish farms by using its WaveEL wave energy technology during lower power consumption in the grid.

Waves4Power also plans to use wave-generated electricity during overproduction periods to make fresh water, oxygen and hydrogen.

The Swedish wave energy developer said the hydrogen could be stored and used as a power source from the fuel cells, with other applications that include powering the vessels.

Under the GPES project, the fresh water and oxygen could be used in debugging of fish and as an additional oxygen source in the net cases to keep the fish healthier, according to Waves4Power.

Ulf Lindelöf, Waves4Power’s Chief Executive Officer, said: “We launched the Green Power EcoSystem at Aqua-Nor fair in Trondheim, and we hope to be able to announce the first project with fish farms at the launch event next week.”

The launch event Lindelöf is referring to is the one that will mark the inauguration of Waves4Power’s wave power system which has been supplying electricity to the Norwegian power grid since June 2017.

The event will take place on September 21, 2017 in Fosnavåg in Norway and will be attended by HM King Harald V of Norway.

Waves4Power’s wave energy system consists of the WaveEL buoy, spanning  8 meters in diameter on the surface, and housing a 35-meter-long vertical tube through its center.

Inside the tube there is a water piston that is pushed up and down by the waves, functioning like a giant pump. The wave energy from this pump is converted into electrical energy.

The energy is evacuated via a specially manufactured dynamic maritime cable to the collection hub, and then through a 3 km long subsea cable to the shore-based power grid.

The WaveEL buoy is anchored by three elastic rods with 40 tons of heavy concrete blocks at the sea bottom. The mooring system allows the buoy free vertical movement while securing it on station.

According to Waves4Power, one WaveEL buoy will produce around 250,000 kWh a year.
