Offshore floating desalination plant goals to provide consuming water from the ocean


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

Plans to make use of marine power to desalinate water acquired an additional increase this week, after a Norwegian agency introduced a system that might be put via its paces in waters off Gran Canaria.

In a press release Monday, Oslo-headquartered Ocean Oasis stated its wave-powered prototype gadget, which it described as being an “offshore floating desalination plant,” was known as Gaia.

The plant — which has a peak of 10 meters, a diameter of seven meters and weighs roughly 100 tons — was put collectively in Las Palmas and can endure testing on the Oceanic Platform of the Canary Islands.

Ocean Oasis stated its know-how would allow “the manufacturing of recent water from ocean waters by harnessing the power of the waves to hold out a desalination course of and pump potable water to coastal customers.”

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

The primary investor in Ocean Oasis is Grieg Maritime Group, which is headquartered in Bergen, Norway.

Desalination

The Canary Islands are a Spanish archipelago within the Atlantic Ocean. In line with the Canary Islands Institute of Expertise, the islands have been “a pioneer within the manufacturing of desalinated water at reasonably priced value.”

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

Whereas desalination — which multinational power agency Iberdrola describes as “the method by which the dissolved mineral salts in water are eliminated” — is seen as a great tool with regards to offering consuming water to international locations the place provide is a matter, the U.N. has famous there are vital environmental challenges linked to it.

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

Inventory picks and investing tendencies from CNBC Professional:

With the above in thoughts, tasks seeking to desalinate water in a extra sustainable approach will change into more and more essential within the years forward.

The thought of utilizing waves to energy desalination isn’t distinctive to the undertaking being undertaken within the Canaries. In April, for instance, the U.S. Division of Vitality revealed the winners of the final stage of a contest targeted on wave-powered desalination.

Again on the Canary Islands, Ocean Oasis stated it might be seeking to assemble a second set up after testing on the PLOCAN facility had taken place. “On this section, the prototype might be scaled with the capability to provide water for consumption,” the corporate stated.

Whereas there may be pleasure concerning the potential of marine power, the footprint of wave and tidal stream tasks stays very small in comparison with different renewables.

In knowledge launched in March 2022, Ocean Vitality Europe stated 2.2 megawatts of tidal stream capability was put in in Europe final yr, in comparison with simply 260 kilowatts in 2020.

For wave power, 681 kW was put in, which OEE stated was a threefold improve. Globally, 1.38 MW of wave power got here on-line in 2021, whereas 3.12 MW of tidal stream capability was put in.

By the use of comparability, Europe put in 17.4 gigawatts of wind energy capability in 2021, in keeping with figures from business physique WindEurope.
