Neom City is a futuristic city that the Saudi Arabian government plans to build in the country’s Tabuk region.

The $500 billion development will include a range of smart technologies and will serve as a “living laboratory and hub for innovation,” according to its planners. It will also be exclusively powered by renewable energy.

According to a new study by KAUST, renewables-powered desalination will play a key role in the city.

It will be critical to ensuring sustainable supplies of water through demand-side management (DSM).
