Pioneering water generation technology for arid regions

Ahbstra identified an untapped gap in the market: the need for a reliable way to generate water from low-humidity air to support basic living needs without placing additional strain on already stressed ecosystems. This demand is especially urgent in arid regions with low humidity, such as southern Spain and California, where conventional water solutions often fall short.

Addressing this need would unlock transformative opportunities for housing, community development and regional growth. Beyond its residential potential, this water-from-air technology could also revolutionise access to clean water for industries including defence and data centres, as well as providing critical support in regions grappling with drought or disruption to water supplies.

But there’s a reason this hasn’t been done before. While extracting water from high-humidity air is relatively straightforward, designing a system that efficiently pulls meaningful volumes of water from low-humidity air posed a far greater challenge, while the sheer scale of the build involved numerous complexities. Solving it required a deep tech approach.

Our first step was to embed sensors through the design, capturing critical data and insights on system performance to fine-tune efficiency. In parallel, we developed a bespoke test rig to validate the tricky desorption cycle, diagnose performance challenges and inform the next stage of development.

This approach proved invaluable. What began as technology the size of an under-counter fridge has been transformed by our systems engineers into a 20-foot build capable of producing 150 litres of water per day. Using CC’s insights, development is underway to further maximise efficiency and reach 500 litres per day while maintaining the current size. This innovation proves the solution works at scale, setting the stage for Ahbstra’s market-leading IP.

Commercialising MOF-based technology for real-world application

At the heart of this breakthrough is the use of metal-organic frameworks – advanced adsorbent materials that act like molecular sponges, selectively capturing and storing chemicals such as water vapour, hydrogen, carbon dioxide or toxic gases from the air. The creation of MOFs recently earned a Nobel Prize win in Chemistry, yet despite hundreds of thousands of MOFs documented in scientific literature, very few have progressed beyond research labs to real-world use.

While MOFs offer exceptional potential, they remain costly. To make large-scale systems possible, we needed rapid thermal cycling on a container-sized machine. Rapid cycling depends on maximising contact between air and MOF to enable efficient adsorption and desorption. Building on Ahbstra’s proprietary drum concept, we had to scale it up to handle 40 times more MOF while maintaining performance.

We needed to manage the energy-intensive process of releasing water from the MOF, which required heating to drive off moisture and then cooling the vapour back into liquid. Unlike conventional systems, our heat pump had to cool its own exhaust, demanding a completely new control strategy, and ultimately a novel heat pump architecture engineered to manage real-world effects and maintain efficiency throughout the cycle.

This integrated novel design – requiring sophisticated thermodynamics, mechanical engineering and airflow management – marks a pivotal step in turning MOF science into practical, scalable technology with real commercial impact.

This project exemplifies CC’s deep tech mindset, developing new-to-the-world solutions that deliver both commercial and societal impact. Reliable water generation in harsh, arid climates offers the potential for applications across humanitarian aid, disaster relief, defence, remote research stations and off-grid housing developments. As climate change accelerates and water scarcity intensifies, demand for resilient, adaptable solutions are only set to grow.

Armed with a first-mover advantage and the breakthrough IP developed in collaboration with CC, Ahbstra is now positioned to shape the commercial landscape of atmospheric water generation with a real-world solution.
