Offshore wave powered desalination, creating fresh water

Global desalination demands are doubling, helping to drought-proof water supplies for the world’s arid urban coastal municipalities. Wave powered desalination represents an innovative solution to meet this growing need as worldwide production of freshwater by desalination is expected to grow from 120 million m3/day in 2022 through to 250 million m3/day by 2030. However, traditional large-scale plants face critical constraints, such as reliance on fossil fuel energy sources, restricted footprints and limited flexibility.

Ocean Oasis delivers abundant fresh water using wave power as an energy source, providing an energy-secure, scalable and cost-effective solution to water scarcity with minimal environmental impact. By harnessing wave powered desalination technology, our innovative desalination buoys can help existing desalination plants to expand capacity and footprint with a flexible, modular solution.

Our commitment to sustainability

Our experienced team has developed a proven solution for sustainable desalination. Our robust offshore design is engineered for durability and efficiency in a marine environment, bringing together an autonomous, low-maintenance operation with remote monitoring and control. By eliminating a reliance on the grid, or fossil fuels, there is no need for an external energy source. Our wave powered desalination solution generates zero emissions, helping to contribute to climate goals. The onboard desalination plant is a chemical-free process that leads to sustainable water production. With offshore brine discharge, it prevents harm to coastal marine ecosystems. Desalinated water is fed to the shore via seabed pipelines, helping to minimize the footprint.

Our solution: wave energy desalination

Using wave energy directly to run the desalination process without conversion to electricity, the Ocean Oasis solution brings together decades of experience from the Norwegian oil & gas industry. The onboard wave energy desalination plant is chemical-free and by bringing together a fleet of buoys, we can help to increase existing plant capacity by 2000 m3/day.

Easily adjusted to meet increasing demand, an Ocean Oasis fleet of desalination units can provide industrial-scale, clean water.

Our wave-powered sea water desalination technology is being proven through successful testing of a full-scale pilot buoy, ‘Gaia’, in Las Palmas de Gran Canaria. The beachhead market is Europe’s largest desalination region, with 180 m3/year capacity growing rapidly.

The cost of sea water desalination

Sea water desalination has historically had the perception of being expensive compared to other water supplies. However, thanks to the advancements in membrane technology over the last 50 years, the cost of sea water desalination has improved considerably. Depending on the water treated (seawater or brackish water), and the scale, desalinated water is getting more cost competitive.

Our business model is to build, own and operate to sell water through long-term contracts. We believe there are strong economics to deliver water at a competitive price. Operating over a 25-year period, the cost of water from our wave powered desalination units would be €1 per 1000 litres.

Milestones reached

Since incorporation in 2020, Ocean Oasis has successfully demonstrated a full-scale pilot in an offshore environment, secured € 10m+ in grants, welcomed the public water utility of Gran Canaria as first customer, and built a strong local consortium for our first-of-a-kind offshore water farm.
