Ocean Oasis unveils energy wave desalination prototype

Norway’s Ocean Oasis has presented the prototype device, called Gaia, for a wave energy desalination that will be tested at the Oceanic Platform of the Canary Islands (PLOCAN).

Ocean OasisThe floating marine desalination plant, which was unveiled in Las Palmas, Gran Canaria, will enable the production of Fresh water from the oceans harnesses the energy of waves To implement a Water desalination Treating and pumping potable water for coastal users.

The prototype, which was assembled in the port of Las Palmas, had a diameter of 7 meters, a height of 10 meters, and weighed about 100 tons.

The device extracts the energy of the waves through the relative motion of two bodies, making use of this energy directly to conduct a desalination process by Reverse osmosis without the need to produce electrical energy, thus increasing the efficiency of the process, Ocean Oasis said.

Gaia will be installed in the southern region of PLOCAN Test Site in Punta de la Marita, according to Ocean Osmosis, which also revealed plans for a second installation after completing trials on the Gaia prototype.

In the second phase of Ocean Oasis technology development, supported by the EU EIC Accelerator, the prototype will be scaled up with the capacity to produce water for consumption, and will be connected to a water distribution system to help address water stress in a sustainable way.

Sebastian WimblattOcean Oasis’ COO said: “The Canary Islands provide us with the perfect environment to test our technology given PLOCAN’s architecture, experience and location, as well as the potential to develop its solution in a market as relevant as the Canary Islands in matters of water desalination and offshore activities.”

Antonio MoralesPresident of the Cabildo de Gran Canaria, added: Gran Canaria depends on desalinated water for its survival, and it is more important every day because of the drought. But desalination is an energy intensive process. If we take into account all the necessary processes for obtaining water, then this is from 15 to 20% of the total energy consumption of our territory.

In 2016, Cabildo de Gran Canaria launched the “Renovagua” plan with the goal of reducing the use of conventional energy in water production and distribution by 40%. Therefore, we receive these types of innovative initiatives with great interest as they can be a very important contribution to ensuring water savings and accelerating energy transmission. “

Desalination growth and marine potential

Currently, more than 300 million people depend on desalination for their water supply, which is about 1% of the total fresh water supply. Climate change and the depletion of traditional resources are increasing the need for desalination, and it is estimated that this will double by 2030 to meet the needs of the population.

However, conventional desalination requires large amounts of energy, resulting in large carbon emissions and high cost. It is in this sense that Ocean Oasis refers to it Desalination using wave energy It brings a new dimension and additional opportunities to supply desalinated water Zero emissionsAt a competitive cost and without using valuable land.

The use of offshore wave energy in deep water also allows for clean water capture and brine discharge in a sustainable manner, reducing environmental impactAccording to Ocean Oasis.
