Project Alpine

Project Alpine is a pilot-scale deployment of Avnos’ proprietary Hybrid Direct Air Capture (HDAC™) technology, developed in partnership with Southern California Gas Company (SoCalGas) with funding support from the U.S. Department of Energy. Located near Shafter in Kern County, California, the project represents the world’s first operational demonstration of Avnos’ hybrid DAC system, which combines moisture-swing adsorption with electrochemical separation to capture CO₂ directly from ambient air. The pilot is designed to remove approximately 30 metric tons of CO₂ per year while simultaneously producing roughly 150 metric tons of distilled water annually, making it a rare example of a “water-positive” DAC system. Unlike conventional DAC approaches that require high-temperature heat input and significant water consumption, the HDAC process relies primarily on electricity and ambient humidity changes, reducing energy intensity and enabling deployment in water-constrained regions. Project Alpine is intended to validate system performance, durability, and scalability, and to support future commercial-scale deployments that integrate carbon removal with co-produced water resources.
