Abstract

Desalination plants could become net absorbers (rather than net emitters) of CO₂. Thermal decomposition of salts in desalination reject brine can yield MgO which, added to the ocean, would take up CO₂ through conversion to bicarbonate. The process proposed here comprises dewatering of brine followed by decomposition in a solar receiver using a heliostat field.
