How it works

The challenge

Thermal desalination is a highly energy-intensive process used to transform saline water into drinkable water by vaporizing the water, separating it from the solid salts. Another desalination process, seawater reverse osmosis (SWRO), involves physically filtering water through a membrane. Historically, this process has also been energy intensive and has proven uneconomical.
