We need water and we need to save energy from renewable sources.

Surplus electricity can be used to make hydrogen from salt water, and when hydrogen is burned to generate energy it releases desalinated water.

It is inefficient yes, but solar is so cheap I think there is an opportunity for a twofer here.

Private enterprises and individuals will deploy solar panels equivalent to several new nuclear plants every year. IMO governments should invest massively in hydrogen infrastructure. Plants, distribution and storage.
