Omar Yaghi has spent three decades quietly reinventing what matter itself can do, and the world is finally catching up. His radical invention, a new class of crystalline materials that can be programmed like Lego at the molecular scale, has already earned him the 2025 Nobel Prize in Chemistry and a reputation as one of the most visionary chemists of his generation. Now he is betting that the same chemistry that won him science’s highest honor can rewrite the future of water, energy, and climate.
At the heart of his claim is a simple but audacious idea: if we can stitch atoms together into vast porous scaffolds with atomic precision, we can pull essential resources like water and clean fuels directly from air and waste streams. That is the promise behind his metal-organic frameworks, or MOFs, and it is why Yaghi insists that what began as a curiosity-driven quest in the lab is poised to transform daily life in some of the most stressed corners of the planet.
The chemist who built a new way to build matter
To understand why Yaghi’s work is being described as world changing, it helps to start with what he actually invented. As colleagues have noted, Professor Yaghi did not just discover a new molecule, he pioneered an entire field of reticular chemistry, in which metal nodes and organic linkers are stitched into extended networks with enormous internal surface area. These metal-organic frameworks behave like molecular sponges, with pores that can be tuned to trap or release specific molecules. A profile of Yaghi describes how he was born in Amman to Palestinian parents and went on to invent a new way to build matter that offers “real solutions for the future,” a trajectory that underscores how personal his drive to tackle scarcity has always been.
That conceptual leap, from isolated molecules to designed frameworks, is what the Nobel committee recognized when it awarded Omar M. Yaghi the 2025 Nobel Prize in Chemistry for his work on metal-organic frameworks, alongside Susumu Kitagawa and Richard Robson of Australia, a decision highlighted by the DOE Office of. UC Berkeley, where he is the James and Neeltje Tretter Professor of Chemistry, celebrated how these “molecular constellations” have transformed materials science worldwide, a point echoed in a university post that hailed UC Berkeley chemist Omar Yaghi for the Nobel Prize. In his own words, captured in a campus interview, “There is nothing like this, it is an astonishment,” he said of receiving the prize, describing the feeling as one you do not have often, a reaction recorded in the Berkeley chemistry coverage.
From Amman to Berkeley, a life shaped by scarcity
Yaghi’s conviction that his invention can change the world is rooted in biography as much as in chemistry. He was born in Amman to Palestinian parents, and he has spoken about how growing up amid political and economic uncertainty sharpened his awareness of basic needs like water and energy. A profile of the 2025 Nobel Prize winner notes that Yaghi, born to Palestinian parents, has “invented a new way to build matter” that is explicitly framed as a toolkit for real solutions. That framing matters, because it shows how his scientific agenda has always been intertwined with a desire to address the vulnerabilities he saw early in life.
By the time he became a former professor of chemistry and biochemistry at UCLA and then the James and Neeltje Tretter Professor at Berkeley, Yaghi had already laid the foundations of reticular chemistry. A detailed account of his career at UC Berkeley notes how his lab’s work on MOFs has rippled across energy, environment, and even the automotive industry, a breadth captured in a research office profile. Another Berkeley news piece describes how, within the last few years, Yaghi and collaborators have extended these frameworks into batteries and the automotive industry, a sign that his early experiences with scarcity have translated into a broad push to reengineer the material basis of modern infrastructure, as detailed in the department’s account.
MOFs: molecular sponges with planetary ambitions
The radical core of Yaghi’s invention lies in what MOFs can actually do. As he likes to illustrate, “If I take a gram of it and unravel it, it will cover many football fields, and that is the space you have for gases to assemble,” a vivid description recorded in a UCLA release. That almost unimaginable surface area is not just a curiosity; it is the reason these frameworks can soak up methane, carbon dioxide, or water vapor with extraordinary efficiency. A separate analysis of MOFs notes that their composition and structure can be tuned to selectively capture and separate gases and liquids, enabling a wide array of applications from gas storage to chemical separations, a versatility highlighted in a national lab overview.
Those capabilities are already being quantified. In the context of methane storage, one assessment found that a fuel tank filled with MOFs can triple the amount of methane stored at room temperature and satisfy the needs of a family, a benchmark cited in the Tang Prize citation for Omar M. Yaghi. Another account of his work explains how these frameworks have become central to efforts to capture and separate gases for climate and energy applications, a trend summarized in a feature on the chemistry behind MOFs. When the Department of Energy highlighted how Omar M. Yaghi has been supported by its Office of Science, it framed MOFs as a platform technology for solving big problems, not a niche curiosity.
Water from thin air, and carbon too
It is in water that Yaghi’s vision becomes most tangible. He has argued that it is possible to pull water out of the air far more efficiently than a dehumidifier, using MOFs that are designed to grab water molecules at very low humidity and then release them with a modest input of heat. A detailed profile of his quest to eliminate water scarcity explains how Yaghi envisions machines that can harvest drinking water from desert air using reticular materials like MOFs, a concept that has already been demonstrated in prototype devices. Another account of this work describes how this Nobel Prize winning chemist dreams of making water from thin air, portraying Omar Yaghi as a quiet, diligent child who grew into a scientist determined to turn that dream into hardware, as recounted in a long-form profile.
These same frameworks can also be tuned to capture carbon dioxide, a dual use that Yaghi has emphasized in public talks. One feature on his work notes that it is possible today to pull water out of the air, but that machines based on reticular materials like MOFs could do so far more efficiently while also targeting carbon, a point underscored in a follow up on his water quest. In another piece, the same Nobel Prize winning chemist is described as working with crystals that can make water from air, with Omar Yaghi portrayed as methodically translating that idea into devices that could sit on a rooftop and supply a household, as detailed in a technology feature. When I look at these accounts together, I see a scientist who is not content with incremental gains in desalination or filtration, but instead is trying to redraw the map of where water can be sourced at all.
From lab to startup, scaling “molecular precision”
Winning the Nobel Prize has not slowed Yaghi’s push to commercialize his frameworks. He is the scientific founder behind a company that describes its transformational technology, designed with atomic precision, as a way to address both the causes and effects of climate change, a mission laid out on the Our Founder page. That same site explains that Omar Yaghi’s work encompasses gas storage, water harvesting, carbon capture, purification, catalysis, and sensing, a list that reads like a roadmap for how MOFs might permeate infrastructure. Another section on Our Technology emphasizes that these materials are designed with atomic precision, a phrase that captures how reticular chemistry turns abstract molecular diagrams into engineered products.
