Are hybrid atmospheric water generation systems a good solution?

Hybrid atmospheric water generation systems are a great solution to increase water productivity and efficiency. The performance and important issues of the reviewed techniques are summarized. Portability of water production system is an important parameter in the design. Utilizing solar energy is a good way to supply system input energy.

What is an atmospheric water generator (AWG)?

Atmospheric water generators (AWG) are now being developed to squeeze water from the air. Many rely on standard condenser and cooling coil technology to collect liquid water. A major drawback is the large amount of energy consumed by these systems and their high operational costs.

Can a solar adsorption system generate atmospheric water?

In another study in 2017, Wang et al. , designed and implemented two solar-powered, adsorption-based systems for generating atmospheric water. The open type device used 2.25 kg of ACF-CaCl 2 composite adsorbent with a solar collector surface of 0.77 m 2 area and a rolled-up sorbent bed produced 0.32 L of water.

Can solar steam generation and passive radiative cooling-enabled atmospheric water harvesting produce freshwater?

Both solar steam generation and passive radiative cooling-enabled atmospheric water harvesting are promising technologies that produce freshwater in green and sustainable ways. Spectral control is extremely important to achieve high efficiency in the two complementary systems based on absorbing/emitting light in a specific wavelength range.

What are the challenges in atmospheric water generation?

The most important challenges in atmospheric water generation can be explained by the following points: There is a greater need to use AWG systems in remote areas, hence, efficient operation, easy transportation, as well as low maintenance expenses are critical issues. Solar-driven systems can ensure wider adaptability as well.

What is solar steam generation?

Solar steam generation is a sustainable technology that converts the abundant and clean solar energy into thermal energy, which is utilized to heat water and generate steam. This is a typical thermodynamic process that must follow the first thermodynamic law of energy conservation.
