“…In other words, with these desiccants, the higher the temperature needed to release water, the more readily the vapor is absorbed [69]. Because of this, they demand high temperatures (more than 160 °C) that are greater than water and can be produced by basic solar photothermal-based heating equipment [70,71]. It was shown that under typical solar irradiation circumstances, certain metal-organic frameworks (MOFs) emit portable water from the air (dry) with RH 10-40 % in laboratory and field settings.…”

Atmospheric water harvesting (AWH) is an important parallel or supplemental freshwater production technique to liquid water resource‐based technologies due to the availability of moisture resources regardless of location and the possibility of realizing decentralized applications. Recent developments to regulate the characteristic features and nanostructures of moisture‐harvesting materials demonstrate new opportunities to improve device efficiency. Focusing on the design of water harvesting materials and the optimization of the overall system, this review sums up the most recent developments in this area and presents prospects for the future development of AWH. An overview of the processes involved in water sorption by various sorbents and the characteristics and functionality of the polyaniline‐based hydrogels developed for AWH is given. Newly reported hydrogel sorbents used for AWH are evaluated, focusing on their benefits, drawbacks, and design methodologies. Several AWH‐specific water harvesters are described and the impact of the system's mass and heat transfer on its operational effectiveness is explored. Finally, potential roadmaps for the development of this technology are detailed and the challenges in this subject from both a basic research and practical application perspective are discussed.

“…109 Alternative routes to produce water include atmospheric water generation schemes, benefiting from the typically high ambient air humidity present across arid regions all year round. 110 Although nowadays the cost of water production by atmospheric water generation remains prohibitive, due to the intensive energy requirements, the versatility of production systems, and the ability to power them with low grade energy or renewables have made them promising supplements to existing desalination and wastewater treatment systems. Current systems offer up to 10 m 3 per day of water production for the footprint of a 20 feet container requiring up to 750− 5000 kWh•m −3 .…”

Biosystems and bioprocesses are typically not connected to arid areas, where the produced biomass and its availability are low. There is however a large potential for arid areas to become major bioeconomical actors via more localized biomass generation strategies. Indoor farming, bioengineering, and aquaculture have a great potential to be at the center of this transition. They are expected to address important challenges associated with food and (bio)materials supply and, ultimately, to climate and environment. Specifically, the utilization of the by- and coproducts deriving from these strategies could synergistically connect into a range of circular processes toward sustainable bioproducts’ supply and the greening of arid areas. These topics are at the center of this perspective, where emerging biomass generation and management strategies in arid areas are introduced. The potential positive feedback loops between their coproducts are then put in relation with the development of more diverse and thriving biosystems as well as the generation of a range of bioproducts. These approaches are contextualized with the current and alternative energy sectors and water treatments processes, which have well-established economical portfolios across most arid areas. The mapping of innovative bioeconomical actors in arid areas and their synergistic interactions, as put forward herein aims to intensify research efforts toward a fully integrated and global sustainable bioeconomy.

“…To address the challenge of producing water in dry climates, materials scientists have been investigating the synthesis and processing of various types of sorbent materials, including minerals such as clays, − silica gel, − metal–organic-frameworks (MOFs), − and polymers. − When exposed to ambient humidity, sorbent materials can absorb water vapor molecules through chemisorption and/or physisorption mechanisms. , The sorbent materials reported in the literature typically require high regeneration temperatures of up to 120 °C in some cases to release water molecules from the sorbent. During the regeneration process, these free water vapor molecules (at higher temperatures and pressures) undergo condensation as they contact colder surfaces with a dew point above that during the water capture stage.…”

We present a new type of sorbent material involving an aluminum heat exchanger coated with a hydrophilic alginate biopolymer hydrogel for atmospheric water harvesting (AWH). The hydrogel-coated heat exchanger is tested in a prototype driving cycle, collecting water over several days of continuous operation. The thermal cycle performance of the coating is tested in dry climates with relative humidity in the range of 30−50%. The new sorbent demonstrates regeneration temperatures between 60 and 80 °C, allowing efficient thermal cycles. The system allowed for a water yield of 2.48−3.3 L/kg Hydrogel /day. The compactness of the coated heat exchanger, together with the performed daily water productivity, makes it compatible with applications integrating AWH technologies in the building sector.
