The world’s first wave-powered desalination system is ready

Water scarcity is a major global crisis that affects two-thirds of the world’s population who do not have access to clean water for at least a month each year. Scientists believe that by 2025, half of the world’s population can live in areas where water is scarce.

The idea of ​​desalination has been around for almost 50 years and seems like a promising solution in the long run. However, the general method of desalination of reverse osmosis (RO) is expensive and quite expensive in terms of energy consumption.

That is why researchers from EU funded project H2020 W2O have come up with a possible solution: off-grid systems powered by renewable energy.

Desalination has become possible with wave-driven technology

While innovative MDC technology following a green, low-energy process with electroactive bacteria for desalination and sterilization of seawater, has been around for some time, and the research team began looking for other simple ways to help developing countries, isolated islands and coastal areas. Then they decided to use the power of ocean waves, an endless and powerful renewable energy source.

Olivier Ceberio, a member of the project team, said that “using the power of the ocean waves technology that can produce fresh water the answer is to the many 2.1 billion people around the world who are fighting for access to safe drinking water, “the press release said.

The team’s revolutionary Wave20 system can be installed quickly, run completely off-grid and produce large quantities of fresh water at a low cost. The new system is the world’s first waveless desalination system that does not require electricity. Wave20 drives free energy from an unlimited energy source with the help of a Wave Energy Converter (WEC) placed on the seabed, which moves back and forth with the waves. Clean!

According to a press release from the European Commission, the daily production of water in the new system can cover the water needs of about 40,000 people, which is great news for people who are dealing with water shortages in remote areas of the world.

For now, the team is testing a small-scale Wave2O model at their test facilities in the United States and will begin deploying the ocean for a second test in the Canary Islands and another later in Cape Verde, the two remote areas that are tackling water scarcity, is stated in the press release.
