Water from Air, Anytime Anywhere
Water is essential to life. It is estimated that by 2050, nearly half of the world population will live in water-stressed regions due to arid conditions or lack of access to clean water. This presentation outlines the parameters of this vexing societal problem and presents a solution to the global water challenge.
Science History Institute
There is plenty of water in the air that can potentially be harvested not only from the desert atmosphere, where the humidity is low, but also from more humid regions of the world where clean water is needed. In principle, the materials used to harvest water from air in these climates should be applicable to deployment anywhere in the world to extract atmospheric water at any time of the year.
Metal−organic frameworks (MOFs) have emerged as a unique class of porous materials capable of trapping water at relative humidity levels as low as 10%, doing so with facile uptake and release kinetics. From laboratory testing to field trials in the driest deserts, kilogram quantities of MOFs have been tested in several generations of devices. The initial results of these experiments showed that MOFs could capture water from desert climates and deliver over one liter per kilogram of MOF per day. More than an order of magnitude increase in water productivity could be achieved with members of the MOF family when employed in an electrified device operating at many cycles per day.
The presentation will show that the vision of extracting clean water from air anywhere in the world at any time of the year is potentially realizable with MOFs, and so is the idea of giving “water independence” to the citizens of the world.
About the Speakers
Omar M. Yaghi is the James and Neeltje Tretter Chair Professor of Chemistry at the University of California, Berkeley. He is widely known for pioneering metal-organic frameworks and covalent organic frameworks. These materials have the highest surface areas known, making them useful for hydrogen and methane storage, carbon capture and conversion, water harvesting from desert air, and catalysis, among others. His approach has led to an exponential growth in the creation of new materials. He termed this field reticular chemistry and defines it as “stitching molecular building blocks into extended structures by strong bonds.”
Yaghi is an elected member of the U.S. National Academy of Sciences, the German National Academy of Sciences Leopoldina, and the Islamic World Academy of Sciences. He is an honorary member of the Indian Academy of Sciences. He has also been honored with many awards, including the Materials Research Society Medal, American Chemical Society Award in the Chemistry of Materials, King Faisal International Prize in Science, Albert Einstein World Award of Science, BBVA Foundation Frontiers of Knowledge Award in Basic Sciences, Wolf Prize in Chemistry, ENI Award for Excellence in Energy, Gregori Aminoff Prize by the Royal Swedish Academy of Sciences, August-Wilhelm-von-Hofmann-Denkmünze of the German Chemical Society, Royal Society of Chemistry Sustainable Water Award, and VinFuture Prize for Emerging Science and Technology.
David R. Moore is the carbon capture technology leader at GE Research. He leads a disruptive technology portfolio with a mission to accelerate the development and deployment of novel engineered material system solutions for atmospheric water extraction and a zero-carbon emissions future.
He is the principal investigator on AIR2WATER, a four-year program with the Defense Advanced Research Projects Agency. Partnering with the University of South Alabama, the University of Chicago, and with Omar Yaghi at the University of California, Berkeley, the team aims to develop a sorbent-integrated prototype that extracts water from the air and produces 150 to 500 liters per day of potable drinking water.
Moore is a classically trained organic/polymer chemist developing novel material systems and has 12 external publications and 21 granted U.S. patents. He holds a PhD in organic chemistry from Cornell University and a BA in chemistry from Drew University.
