So much water in the sea… and not being able to drink it. Is that true? No, not so much anymore. Argentine scientists are making seawater drinkable. They have created equipment that desalinates ocean water. It would turn it into an accessible resource for areas that have shortage problems. The plant created for this purpose works with green hydrogen. And for this reason, it has no impact on the environment.
The water problem
The research began in the city of Caleta Olivia, in the province of Santa Cruz, in the south of the country. There, difficulties in access to drinking water soon became evident.
The study is in charge of the scientist of the National Council of Scientific and Technical Research (Conicet). The National University of Southern Patagonia (UACO) is collaborating. Adrian Brunini is a researcher. He developed a water heater that transforms seawater into drinking water.
It is detailed to the website of the scientific body. The technology created reproduces the water cycle. “It is thermal energy, efficient and does not require great technological advances. It can work in a desalination plant,” he said.
In addition, its operation could be based on green hydrogengenerated by renewable energies. It has a global role in decarbonizing industries. So it would not have a negative impact on the environment. This is because it does not generate greenhouse gases.
The water of the future
According to Brunini, the pilot plant features a thermodynamic design. It recovers most of the energy used. First, seawater is heated to bring it into contact with dry air. What does this do? This causes the air to become humid. Then the air succeeds in absorbing the moisture from the water and discriminating the salt.
The last step is to condense the moisture present in the air. This is how you get the drinking water separated from the sea salt. And that’s it, you are making seawater drinkable.
The promising initiative is intended to be a bet on the future. It will help strengthen the country’s sovereignty in terms of technological developments.
