Challenges and Strategies Toward Sustainable Atmospheric Water Harvesting

Abstract

Facing the growing stress on freshwater supplies, harvesting water from the atmosphere via sorbents has garnered significant attention due to its broad applicability, regardless of geographic and hydraulic restrictions. In advancing the sustainable development, two critical aspects are the use of biomass-derived sorbents and solar energy. Biopolymers offer viable alternatives to petroleum-derived synthetic polymers, presenting opportunities for developing environmentally friendly AWH systems. Additionally, efficient capture and utilization of solar energy to drive water desorption are also critical to enhancing the sustainability of AWH.
