- For example, Ocean Oasis claims that its technology would allow for “the generation of fresh water from ocean waters by harnessing the energy of the waves to carry out a desalination process.”
- Several entities, such as Innovation Norway and the Gran Canaria Economic Promotion Society, have contributed funding toward the prototype’s development.
- The Canary Islands are a chain of islands off the coast of Spain in the Atlantic.
The goal of a wave-powered prototype gadget is to produce drinking water from the ocean: It was announced this week by a Norwegian company that they have developed a device to desalinate water using marine energy, and it will be tested in the waters off the coast of Gran Canaria.
Ocean Oasis, headquartered in Oslo, released a statement on Monday announcing the name of their prototype device, powered by waves and characterized as an “offshore floating desalination plant” (Gaia).
The plant, which will be tested at the Oceanic Platform of the Canary Islands, was assembled in Las Palmas and measures 10 meters in height, 7 meters in diameter, and weighs around 100 tonnes.

“the creation of fresh water from ocean waters by harnessing the energy of the waves to carry out a desalination process and pump potable water to coastal users,” Ocean Oasis claimed their technology would make possible.
The firm claimed that multiple entities, including Innovation Norway and the Gran Canaria Economic Promotion Society, contributed funding toward the creation of its prototype.
Grieg Maritime Group, based in Bergen, Norway, is Ocean Oasis’ primary backer.
Desalination
Located in the Atlantic Ocean, the Canary Islands are Spanish territory. The islands have been “a pioneer in the production of desalinated water at affordable cost,” as stated by the Canary Islands Institute of Technology.
Some of the ITC’s arguments are presented here. The “structural water deficit due to low rainfall, high soil permeability, and aquifer overexploitation” is cited as an example of a “water singularity” that characterizes the Canary Islands.
The United Nations has pointed out that there are considerable environmental issues associated with desalination, which is “the process by which the dissolved mineral salts in water are removed,” according to the international energy corporation Iberdrola.
There is a statement that says, “the fossil fuels generally employed in the energy-intensive desalination process contribute to global warming, and the poisonous brine it creates pollutes coastal habitats.”
Keeping foregoing in mind, initiatives aiming to desalinate water in a more sustainable way will grow in significance over time.
The Canary Islands’ proposal isn’t the first to consider harnessing the power of waves for desalination. For instance, in April, the United States Department of Energy announced the final winners of a competition centered on wave-powered desalination.
After testing at the PLOCAN plant was completed, Ocean Oasis stated that it would try to build a second site back in the Canary Islands. Water production capacity will be added to the prototype at this stage, the business stated.

Although there is enthusiasm for marine energy’s potential, the impact of wave and tidal stream installations is still very tiny when compared to other renewables.
Ocean Energy Europe reported in March 2022 that Europe had installed 2.2 MW of tidal stream capacity in the previous year, which was a significant increase from the 260 kW installed in 2020.
OEE reported a threefold increase in the installation of wave energy systems, totaling 681 kW. In 2021, 1.38 MW of wave energy and 3.12 MW of tidal stream capacity were brought online around the world.
According to WindEurope, an industry group, Europe installed 17.4 GW of wind-generating capacity in 2021.
