Direct electrosynthesis of sodium hydroxide and hydrochloric acid from brine streams | Nature Catalysis
recycling output brine from desalination plants to make sodium hydroxide in bulk. Apparently desal plants normally have to buy it to adjust input salinities, so producing it's own makes some sense...

Interesting use of recyclable hydroxides to reform biomass or coal/methane into hydrogen in one step at low temperatures with high hydrogen purity and no CO or CO2 production. Though if you want the CO or CO2, you can heat the resulting carbonate output (recaustication like at paper mills) to recover a relatively pure gas stream and recover the hydroxide for recycling back into the process inputs.
