Review maps four technical pathways for atmospheric water harvesting and links refrigeration to SDG 6
A 2026 review in Applied Thermal Engineering outlines four approaches to extracting freshwater from air — condensation, sorption, radiative cooling, and hybrid systems — and highlights MOFs operating at 10–20 % relative humidity and a solar-powered thermoelectric prototype as key advances. The IIR's 60th Technical Brief positions refrigeration-based AWH as a contributor to UN Sustainable Development Goal 6.
