Ocean Oasis wants to make drinking water at sea, using the energy of waves. The company, founded in Oslo in 2020, builds buoys that desalinate seawater offshore with no grid connection and, it says, no carbon dioxide emissions.
The European Innovation Council granted €2,500,000 towards a €3.60 million project, ReWater, which ran from August 2022 to March 2025 and validated the "Gaia" prototype buoy off Gran Canaria. Ocean Oasis now leads DesaLIFE, a project of about €10 million co-funded by the EU LIFE programme, to build "Theia", an industrial unit designed to supply 2,000 cubic metres of water a day. In October 2025 the Canary Islands recognised it as a strategic project.

Where Ocean Oasis Stands Today
Ocean Oasis's news page in 2026 focuses on DesaLIFE: the strategic project status in the Canary Islands, a study with the city of Las Palmas de Gran Canaria on wave-powered desalination, and what it calls a deepening institutional engagement. The first industrial unit, Theia, will be "built locally in the Canary Islands"; no completion date has been announced. Its 2025 accounts in the Brønnøysund Register show operating revenue of NOK 6.0 million, a net loss of NOK 2.6 million and equity of NOK 15.9 million.
The Technology: A Desalination Plant That Floats
Ocean Oasis's buoys harness wave motion to run the desalination process at sea. The Gaia prototype was tested over two years of development, laboratory work and open-sea trials, which the Port of Las Palmas' president called a "strategic solution" for producing drinking water without depending on the grid.

Beatriz Calzada, President, Port Authority of Las Palmas, 2025What the EIC Project Promised, and What CORDIS Shows
ReWater promised "offshore renewable and clean desalination of sea water". The company reports that it validated Gaia at sea; it has not published how much water the prototype produced or for how long it ran. The next phase, DesaLIFE, moves from one prototype to an industrial unit.

What Has Happened Since the Award
The Money
The award was "grant first"; we found no EIC Fund investment. Ocean Oasis has announced a capital raise and welcomed investors on its website, and DesaLIFE brings further EU money through the LIFE programme. Its 2025 accounts show a modest loss and positive equity.
What cannot be checked
How much water Gaia produced, at what cost per cubic metre, when Theia will start operating and who Ocean Oasis's investors are are not public in the sources we used.
Why Europe Should Care
The Canary Islands government backs the project as part of its water strategy, and desalination powered by waves rather than the grid would avoid the emissions of conventional plants. The EU has now funded Ocean Oasis twice, through the EIC and LIFE.
What the project promised
Offshore desalination powered by renewable wave energy.
What the record shows
A validated prototype buoy and a funded industrial unit in the Canary Islands; no published output data yet.
The Verdict
Proven at sea, industrial scale next
ReWater got a wave-powered desalination buoy working at sea, and Ocean Oasis has secured the next step with EU and regional support. The test is whether Theia delivers its 2,000 m³ a day at a price that can compete.
