Regeneration Optimized Sorbent (ROS) Materials

The new technology we have developed is a new class of next generation industrial desiccant materials called Regeneration Optimized Sorbents (ROS).

The key feature of our new sorbent materials, is that they reduce the energy required to absorb and desorb water vapor. This feature unlocks energy-efficient humidity management, enabling more efficient desiccant dehumidifier operation, and for a new class of Hybrid Atmopsheric Water Extraction designs to be realized.

ROS materials are not only energy-efficient, but are novel in their ability to function in low humidity environments, and at near freezing temperatures. This allows them to be used to supercharge Atmospheric Water Extraction in harsh environments, making them a natural fit for improving humanitarian, civil and defense water resilience and security.

The technology emerged from decades of research, and is entering commercial markets in 2020. The proven supply chain is based in the USA.

Energy-Efficiency due to superior kinetics

ROS’s efficiency is due to its superior kinetics, which outperform all other published sorbent candidates. ROS sorbents function like traditional desiccants, but use less energy to regenerate (eject their water vapor load) at a much lower temperature than traditional desiccants (49°C instead of up to 200°C). This results in dramatically improved energy-efficiency and lower temperature exhaust from buildings HVAC systems, a functional way to stop carbon emissions before they start.

This lower energy footprint is important, because it unlocks the ability to design new desiccant/refrigerant based Atmospheric Water Extraction (AWE) equipment to operate more effectively than current technology permits. ROS’s speed of absorb/desorb cycle time, coupled with lower temperature of operation enables successful water extraction, which can be scaled from 5 gallons per day to 5,000 gallons per day, offering a new tool in water resilience technology.

We have built working prototypes, have a vertical supply chain in the USA, and are offering pilot-project demonstration programs during the 2020 fiscal year to approved interested parties. We are currently accepting applications for funded demonstration unit pilot programs for 2020-2021.

Our Tech Story

Watch our 17-minute video explaining how our materials are going to reduce the amount of energy we use and solve for the world water crisis. 


Water from air takes its origins as a byproduct of refrigeration and air conditioning equipment. In recent years, interest in Atmospheric Water Extraction has been accelerating as water resilience becomes an  increasingly important policy issue.

We developed the Regeneration Optimized Sorbent materials to solve the low humidity problem, by having the fastest and most efficient kinetics of any sorbent material. The result is that a new type of Atmospheric Water Extractor design (as pictured here) could use highter intake airflows to compensate for low water grain counts, thus boosting water productivity under a wide array of environmental conditions.

Because the innovation is simply a material change to replace silica used in desiccant dehumidifiers, the technology is thus scalable to virtually any size, from 5 gallons per day to 5,000 gallons per day. This means that machines can be developed to support individual to micro-grid municipal scale applications.

To prove ROS’s superior Atmospheric Water Extraction (AWE) performance, we designed and built a new Hybrid design functional prototype, which levers ROS’s superior kinetics profile to produce water from air, even when it’s cold and dry outside, where normal AWE machines fail. Watch the above video to see more about our working prototype, or use our contact page to learn more.


The ROS class of materials hold the potential to revolutionize energy-efficiency for the humidity management market. ROS’s superior kinetics lowers the amount of energy required to desorb the water vapor load from the ROS material, thus lowering the temperature and energy requirement needed during the regeneration cycle. This is key for reducing operating expenses and emissions from many industries where dehumidification is important, including pharmaceutical, food packaging, dairy production, chemical processing, cosmetics manufacturing, petroleum refining, office building HVAC management systems and many others.

Industrial and commercial water vapor humidity management is one of the largest consumers of energy on the planet. By reducing the energy requirement for water vapor sorption regeneration, ROS technology can have a significant positive environmental impact.
