H2OLL

H2OLL is an Israeli water technology company that has developed a patented cyclic absorption atmospheric water generation (AWG) system designed to produce clean drinking water in arid and semi-arid climates. Unlike traditional AWGs that rely on energy-intensive cooling to condense moisture, H2OLL utilizes a liquid desiccant to absorb water vapor from dry air—operating efficiently even when absolute humidity is as low as 5g/kg. This salt-based desiccant also serves as a physical barrier and natural sterilizer, preventing biological and chemical contaminants from entering the water. The systems are designed as modular, containerized units capable of integration with various energy sources, providing a scalable, sustainable alternative to trucked or bottled water.

The technology addresses global water scarcity by offering a decentralized, on-site water source for industries, hospitality, real estate, and emergency services. By eliminating the logistics, plastic waste, and variable quality associated with traditional water supply chains, H2OLL aims to provide reliable water security. The company’s systems have been deployed in pilot projects, such as in the Negev Desert, demonstrating the ability to produce 1,000 liters of water per day with significant energy efficiency gains. Originating from research at the Technion—Israel Institute of Technology, H2OLL continues to scale its operations with plans for larger capacity units to support broader community and industrial needs.
