AWH based on moisture harvesters captures vapor from the air via absorption or adsorption, which refers to the attachment of water molecules to materials through physical or chemical processes (Figure 2a). Linear driving force (LDF) model (54,55);) assumes that the temperature of adsorbent particles is uniform (does not vary with radius) at all times and the vapor partial pressure is constant, is used to describe mass-transfer by eq 4where μ is the sorption rate (s–1), *x*\* and *x* are the equilibrium and the dynamic water uptake of the adsorbent, respectively, and *k*1 is the LDF adsorption rate coefficient (s–1) and is positively related to the diffusion coefficient (*D*e) and negatively related to the adsorbent particle size (*r*0): (25);)It is worthy noting that the sorption behavior of current moisture harvesters is usually exhibited as the combination of physisorption and chemisorption, and may involve absorption as well. Through proper material selection and rational modification, an ideal moisture harvester with high water uptake, low generation energy demand, fast sorption/desorption, and cycling stability can be obtained for efficient AWH.

AWGs capture water from air — a process that provides reliable solutions for areas with limited access to traditional water sources. ## Atmospheric Water Harvesting Based on Reticular Materials. In their search for answers, the community discovers atmospheric water harvesting — a way to pull clean, life-giving water directly from the air around them. Traditional atmospheric water harvesting methods come with challenges — energy costs and dependence on humidity — but innovations like Atoco’s nano-engineered materials can mitigate these issues leveraging free ambient energy. ## Atmospheric Water Harvesting. ## What is Atmospheric Water Harvesting? While condensation and desiccant methods struggle in arid areas, reticular materials push the limits of water harvesting. ## Atoco’s Water Harvesting Solutions. The future of atmospheric water harvesting lies in harnessing novel technologies such as our nano-engineered reticular materials to provide reliable, efficient, and sustainable water solutions for the world’s most water-stressed regions. Atoco develops water harvesting solutions that efficiently harvest clean water out of the atmosphere, even under dry conditions with relative humidity below 20%.

From this, they generated a map of which atmospheric water harvesting methods are the most energy efficient in certain areas of the world. They recently received a grant from the Shah Family Global Innovation Lab to bring these methods to Kédougou, Senegal, where seasonal rains (and lack of clean groundwater) make atmospheric water harvesting a viable option. He continues: “Looking at the map, it’s interesting that the areas where atmospheric water harvesting is most efficient are also places where water quality is a constant worry. Atmospheric water harvesting is not just about scarcity; it’s about water quality as well.”. “This presents an opportunity, because if you pick the right technology, atmospheric water harvesting becomes a more feasible alternative to bring freshwater to more areas of the world.”. We’re excited to provide a literal map for the future development of atmospheric water harvesting technologies.”. *ABSTRACT: Atmospheric water harvesting (AWH) is a rapidly emerging approach for decentralized water production, but current technology is limited by trade-offs between energy consumption and yield.

These conditions make it possible to capture water vapor using desiccant-based technology, the most promising method for dry climates like Arizona’s. Due to rapid advancements in desiccant-based technology, numerous atmospheric water harvesting companies have emerged in Arizona over the past four years. This is an enormous amount, especially when compared with the half million acre-feet that Arizona imports as liquid water from the Colorado River each year — which, by the way, all evaporates back into the atmosphere during use in central Arizona. This highlights the potential for atmospheric water harvesting as a viable and sustainable water source, even in an arid climate like Arizona’s. Experts project that within five to 10 years, atmospheric water harvesting will reach cost parity with municipal water, even in arid regions like Arizona. **A:** One important goal was to contribute to developing a 20-year atmospheric water harvesting roadmap. **A:** Atmospheric water harvesting technology is no longer just an emerging concept — it is already being deployed.
