Saudi Arabia plans to use a new solar technology to desalinate seawater at Neom, a mega-city that it’s developing along the country’s northern Red Sea coast.

Neom will have the world’s first “solar dome” desalination plants, which it said will produce no carbon emissions and create less brine than facilities using conventional reverse osmosis technology, according to a statement. The solar dome plants will also process drinking water more cheaply than conventional plants, at 34 cents per cubic meter, Neom said.
