I came across this interesting article in “The Chemical Engineer” on two water desalination pilot plants being planned  in Jordan and Israel, with the unlikely assistance of NATO.

Desalination – at low power by Justin Blows

The Canadian company SaltWorks is commercialising what appears to be a radical desalination technology that needs much less electrical power than traditional approached.

Instead of either evaporation followed by condensation or reverse osmosis, the SaltWorks technology uses ion bridges that selectively pass either chlorine or sodium ions in an ionic circuit that strips salt from a stream of salty water.

This article has an accessible summary of the technology.
