Water Harvesting, Inc. (WaHa) was formed in 2018 to commercialize atmospheric water harvesting systems based on metal organic frameworks (MOFs) and address the global challenge of water scarcity. The company’s MOF-based technology extracts water from air, even in the driest conditions. Metal Organic Frameworks (MOFs) are a class of materials characterized by very high porosity, that can be tailored to selectively adsorb and capture a wide variety of chemical compounds. Developed at UC Berkeley, WaHa’s MOF technology is tailored for harvesting water from the atmosphere in relative humidity levels as low as 15%. In contrast to conventional atmospheric water harvesting systems, the company’s MOF-based technology captures only water molecules, and is capable of rapid adsorption/ desorption cycling. This ensures absolute water purity, with a low energy requirement.
