A Palestinian-Jordanian chemist who grew up hauling water for his family in Amman has invented the crystal technology to pull drinking water from desert air, won the Nobel Prize for it, and is now deploying it commercially.
Somewhere in the Mojave Desert in early 2026, a shipping-container-sized machine built by a Nobel Prize-winning chemist named Omar Yaghi is pulling drinking water out of air so dry it gives you nosebleeds. The machine contains no pipes connected to any river or aquifer. It draws no water from the sky. It simply breathes in arid air and, through crystals that Yaghi spent three decades inventing, extracts the invisible moisture suspended within it, producing up to 1,000 liters of clean water per day at humidity levels as low as 10%. This is not a laboratory demonstration. It is a commercial prototype, the product of a life story so precisely mirrored in the technology it produced that it reads less like biography and more like a closed equation: a boy who grew up in Amman hauling water buckets for his refugee family every two weeks invents a crystal material that makes water independence possible anywhere on Earth, wins the Nobel Prize for it, and then builds a company to give it away at scale. The crystal is called a metal-organic framework. The company is called Atoco. And the man who built both of them has been working toward this moment, in one way or another, since he was ten years old.
Omar Yaghi was born in 1965 in Amman, Jordan, to a Palestinian refugee family that had fled the village of Al-Masmiyya during the 1948 expulsions. His parents could barely read or write. He grew up as one of ten children in a single room shared with livestock, separated from the animals only by sacks of feed. There was no electricity, and no running water. Municipal taps turned on once every two weeks, for a few hours at a time.
If young Omar did not rise before dawn to open the family tap, his parents, seven brothers, and two sisters went without water. As he grew older, his father trusted him with the cattle too: the best cuts at the family butcher shop came from well-hydrated animals, and that meant managing scarcity carefully. Decades later, speaking at a Nobel ceremony in Stockholm, Yaghi framed his entire scientific career in those terms: "I feel like I've gone from scarcity to abundance through science."
That trajectory has now taken a remarkable commercial turn. In October 2025, Yaghi shared the Nobel Prize in Chemistry with Susumu Kitagawa of Kyoto University and Richard Robson of the University of Melbourne for developing metal-organic frameworks (MOFs), a class of porous crystalline materials he pioneered at UC Berkeley. And the company he founded on the back of that research, Atoco, is testing machines that produce 1,000 liters of drinkable water per day from desert air, without access to any river, aquifer, or cloud.
Metal-organic frameworks are synthetic porous materials built from metal ions linked to organic molecules in a repeating crystal lattice. The key property is internal surface area: just one gram of a water-absorbing MOF contains an internal surface area of roughly 7,000 square meters, more than the footprint of a football arena. That extraordinary surface area is available for trapping and releasing specific molecules, which means MOFs can be designed for carbon capture, hydrogen storage, gas filtration, or, most urgently for Yaghi, water absorption.
The epiphany for water harvesting came in 2014, when Yaghi's Berkeley team realized that MOF pore sizes could be tuned to attract water vapor at very low humidity levels and then release that water with minimal heat input. Traditional atmospheric water generators rely on refrigerant-based compressors that work reliably only above 20% relative humidity; below that threshold, the physics become prohibitively energy-intensive. Yaghi's MOFs work at 10 to 20% humidity, which is precisely the range found in the world's most water-stressed arid environments.
He and his colleagues published a breakthrough aluminum-based MOF in 2023 that is substantially cheaper to produce in bulk than earlier zirconium-based versions. Prototype devices using the material have achieved 200 liters of water output per kilogram of MOF per day with small amounts of added heat. That ratio matters enormously for commercial scale.
Yaghi founded Atoco in 2020 to commercialize MOF technology for both water harvesting and carbon capture. The company's flagship water machine measures roughly 20 feet in length, a shipping-container-scale unit capable of producing up to 1,000 liters per day. It uses moving air to draw in moisture and ambient sunlight, or low-grade waste heat, to drive the absorption-release cycle. Atoco also offers an on-grid version that uses electricity to accelerate throughput. Field tests have been run in Death Valley, California, one of the most arid environments in North America, where humidity regularly drops into the low teens.
Atoco's commercial thesis is explicitly analogous to off-grid solar: the company calls its product "personalized water," positioning households and communities as independent water generators rather than consumers of centralized infrastructure. Magnus Bach, Atoco's VP of business development, has pointed to the company's unique asset: access to Yaghi's own lab at Berkeley means Atoco can design bespoke MOFs optimized for specific humidity conditions and applications, rather than relying on off-the-shelf materials from industrial chemical suppliers. The next round of field deployments was scheduled for the Mojave Desert in early 2026.
Atoco is not alone. A competitor, AirJoule, has deployed MOF-based water generators in Texas and the UAE, using a commercially available MOF from BASF and backed by researchers at Arizona State University. The presence of multiple companies racing to scale the same underlying science is a signal of how seriously the atmospheric water harvesting market is being taken. Industry analysts have estimated the market is already worth billions of dollars globally and is on a steep growth trajectory.
Separately, Yaghi co-founded WaHa Inc. in 2018 to focus on Middle East water harvesting applications. WaHa now works with researchers at Lawrence Berkeley National Laboratory on translating MOF technology into building systems, including space cooling, dehumidification, and pharmaceutical cold storage.
The timing of Atoco's commercial push coincides with a wave of competing atmospheric water harvesting approaches, each addressing slightly different conditions and use cases.
At MIT, Professor Xuanhe Zhao of the Department of Mechanical Engineering has developed a passive, electricity-free water harvester built from origami-shaped hydrogel panels enclosed in a glass solar still. The device, published in the journal Nature Water in June 2025, absorbs moisture from air overnight through a lithium-chloride-infused black hydrogel and then releases the water as vapor when solar heat builds up through the day; that vapor condenses on the glass inner surface and drains into a collection tube. In a week-long field test in Death Valley, the meter-scale prototype collected between 57 and 161 milliliters of safe drinking water per day across humidity conditions ranging from 21 to 88%. The device has no moving parts, no electricity requirement, and a tested lifespan of at least one year. Zhao's vision is arrays of vertical panels at household scale, deployed in regions where even a solar cell is unaffordable.
At UNLV, Professor H. Jeremy Cho founded WAVR Technologies in 2024 out of research inspired by the biology of tree frogs. WAVR's system uses a hydrogel membrane whose surface chemistry segregates wet and dry zones, continuously cycling water from vapor to liquid without stopping for recharging. Tested in Las Vegas conditions, the system is effective at humidity levels as low as 10% and produces approximately one gallon per square meter per day. WAVR was the first company to launch with backing from the NSF's Southwest Sustainability Innovation Engine (SWSIE), a multi-million-dollar program encompassing Arizona State University, UNLV, the University of Utah, the Desert Research Institute, and more than 100 regional partners. In early 2025, WAVR closed a $4 million funding round and received additional SWSIE innovation grant funding.
The convergence of these parallel programs is not coincidental. The context is a global freshwater crisis that has been building for decades. Aging snowpack feeds less meltwater to rivers. Aquifers drained by agriculture and sprawling cities are being replenished slower than they are drawn down. Rising seas push salt into coastal groundwater. And according to the U.S. Government Accountability Office, PFAS "forever chemicals" contaminating water supplies may represent the most severe water quality crisis since lead.
For Yaghi, the Nobel Prize capped a career whose trajectory was defined by scarcity. He left Jordan alone at 15, landing in Troy, New York, supporting himself by bagging groceries and mopping floors while he enrolled at Hudson Valley Community College. He transferred to SUNY Albany for a chemistry degree, then earned his PhD at the University of Illinois at Urbana-Champaign in 1990 under Walter Klemperer. After a postdoctoral fellowship at Harvard, he moved through the University of Michigan and UCLA before joining UC Berkeley in 2012, where he holds the James and Neeltje Tretter Chair in Chemistry and, since May 2025, the title of University Professor, the UC system's highest academic distinction.
More than 100,000 distinct MOF structures have been synthesized since Yaghi's foundational work in the 1990s. The Nobel Committee described the material as capable of harvesting water from desert air, capturing carbon dioxide, storing toxic gases, and catalyzing chemical reactions, a breadth of application unusual even for Nobel-recognized chemistry. Yaghi himself has described MOFs in terms that echo his childhood: the structure is designed, atom by atom, to do exactly the job required, and not a molecule wasted.
What he is building now, in the Atoco machines headed for the Mojave and eventually to arid communities worldwide, is the direct descendant of those early mornings watching the municipal taps in Amman. The crystal he invented in a Berkeley laboratory is engineered to do what the water truck once did: arrive reliably, deliver what is needed, and leave no one waiting. "My dream," Yaghi has said, "is for everyone to have water independence, where your water is yours, independent of everything else."
If Atoco's commercial thesis holds and the off-grid water model scales the way off-grid solar did, that independence would not just be a personal ambition. It would be a rewrite of how billions of people relate to the most basic resource on Earth.
