Recent Advancements in Atmospheric Water Harvesting Technology:
Atmospheric water harvesting (AWH) has seen significant advancements in energy harvesting and conversion technology, including new mechanisms and technical paths [1, 2].
Modern technologies for AWH include various prototypes and methods such as radiative cooling, solar distilling, and sorption-based water collecting, each with different capture materials, system designs, and thermodynamic cycles [2].
A thermodynamic and technoeconomic framework has been developed to evaluate different AWH systems based on performance metrics and compare them to desalination, providing insights into the energy consumption and costs associated with practical AWH systems [3].
A novel absorption-based atmospheric water generator has been proposed to improve the feasibility and cost-effectiveness of AWH, demonstrating the potential for producing fresh water even in arid regions [4].
Environmental Impacts of Atmospheric Water Extraction:
AWH has the potential to provide a sustainable water supply, particularly for arid and land-locked regions, and can serve as an alternative to using expensive bottled water in post-disaster emergencies [5, 6].
A study comparing the productivity, energy consumption, efficiency, cost, and quality of water produced by different AWH mechanisms found that water collected by desiccant-based technologies had significantly lower conductivity, metals, and turbidity, indicating potential environmental benefits [7].
Comparison to Traditional Water Sources in Terms of Cost and Efficiency:
A thermodynamic comparison of different AWH technologies revealed that the minimum energy requirement for AWH processes varies based on environmental conditions, with sorbents having a particular niche in colder, arid regions [8].
The cost of water generated through AWH has been examined and compared to the cost of bottled water, demonstrating that AWH is cost-effective and takes significantly less time to break even compared to bottled water [9].
Challenges and Limitations of Atmospheric Water Harvesting:
Challenges and barriers remaining in current AWH technologies have been identified, and a realistic pathway to improve process performance has been proposed, emphasizing the need for a transition to more sustainable and cost-efficient AWH implementation [10].
While AWH has advantages compared with bottled water in both cost and environmental impacts, the high price and low water generation rate make this technology unfavorable as a viable alternative to general potable water sources, indicating limitations in scalability and cost-effectiveness 5.
The scalability, long-term outdoor practicability, and cost-effectiveness of passive AWH technologies need further improvements, highlighting the challenges in achieving widespread adoption of AWH systems [11].
In conclusion, recent advancements in atmospheric water harvesting technology have shown promise in addressing water scarcity, but challenges such as scalability, cost-effectiveness, and environmental impacts need to be addressed to maximize the potential of AWH as a sustainable water source.
