Offshore floating desalination plant aims to produce drinking water from the ocean

Ocean Oasis’ Gaia machine has been designed to make use of wave energy to desalinate water.

Plans to make use of marine calories to desalinate water won an additional spice up this week, after a Norwegian company introduced a machine that might be put thru its paces in waters off Gran Canaria.

In a commentary Monday, Oslo-headquartered Ocean Oasis mentioned its wave-powered prototype instrument, which it described as being an “offshore floating desalination plant,” used to be referred to as Gaia.

The plant — which has a top of 10 meters, a diameter of seven meters and weighs more or less 100 heaps — used to be put in combination in Las Palmas and can go through trying out on the Oceanic Platform of the Canary Islands.

Ocean Oasis mentioned its era would allow “the manufacturing of unpolluted water from ocean waters by means of harnessing the calories of the waves to hold out a desalination procedure and pump potable water to coastal customers.”

The corporate mentioned the advance of its prototype had won monetary backing from a variety of organizations together with Innovation Norway and the Gran Canaria Financial Promotion Society.

The principle investor in Ocean Oasis is Grieg Maritime Workforce, which is headquartered in Bergen, Norway.


The Canary Islands are a Spanish archipelago within the Atlantic Ocean. Consistent with the Canary Islands Institute of Era, the islands were “a pioneer within the manufacturing of desalinated water at reasonably priced price.”

A presentation from the ITC highlights one of the vital the reason why. Describing the Canary Islands’ “water singularities,” it refers to a “structural water deficit because of low rainfall, prime soil permeability and aquifer overexploitation.”

Whilst desalination — which multinational calories company Iberdrola describes as “the method during which the dissolved mineral salts in water are got rid of” — is observed as a great tool in terms of offering consuming water to nations the place provide is a matter, the U.N. has famous there are important environmental demanding situations related to it.

It says that “the fossil fuels usually used within the energy-intensive desalination procedure give a contribution to world warming, and the poisonous brine it produces pollutes coastal ecosystems.”

With the above in thoughts, tasks having a look to desalinate water in a extra sustainable means will turn out to be increasingly more necessary within the years forward.

The speculation of the use of waves to energy desalination isn’t distinctive to the mission being undertaken within the Canaries. In April, as an example, the U.S. Division of Power published the winners of the closing level of a contest all for wave-powered desalination.

Again at the Canary Islands, Ocean Oasis mentioned it might be having a look to build a 2d set up after trying out on the PLOCAN facility had taken position. “On this section, the prototype might be scaled with the capability to provide water for intake,” the corporate mentioned.

Whilst there’s pleasure about the possibility of marine calories, the footprint of wave and tidal circulation tasks stays very small in comparison to different renewables.

In knowledge launched in March 2022, Ocean Power Europe mentioned 2.2 megawatts of tidal circulation capability used to be put in in Europe closing 12 months, in comparison to simply 260 kilowatts in 2020.

For wave calories, 681 kW used to be put in, which OEE mentioned used to be a threefold build up. Globally, 1.38 MW of wave calories got here on-line in 2021, whilst 3.12 MW of tidal circulation capability used to be put in.

By the use of comparability, Europe put in 17.4 gigawatts of wind energy capability in 2021, in step with figures from trade frame WindEurope.
