Tech company AirJoule has signed an agreement with the city of Hubbard, Texas to deploy their air-to-water technology using low-grade heat from geothermal.
AirJ0ule Technologies Corporation (NASDAQ: AIRJ) (AirJoule Tecnologies) has announced an agreement to deploy its proprietary AirJoule air-to-water system in the city of Hubbard in Texas. The planned pilot is unique in that it aims to use a geothermal water well as a source of low-grade heat to produce pure high-value distilled water from ambient air. The project is expected to commence by Q4 2025 and be completed by Q1 2026.
The technology of AirJoule uses a proprietary metal organic frameworks (MOF) coating to capture water from air. Unlike conventional systems, AirJoule eliminates the need for harmful refrigerants and works in both humid and arid environments. The company has partnered with the GE Vernova Advanced Research Center in Niskayuna, New York, which confirmed that the process can produce PFAS-free distilled water.
“This project highlights an important application of our AirJoule® platform: the ability to unleash the power of water from air by using low-grade waste heat to produce high-value distilled water from the air at the point of use,” said Matt Jore, CEO of AirJoule Technologies. “While this project uses geothermal heat, the same platform can use waste heat from manufacturing operations and energy production infrastructure—unlocking a distributed and sustainable water solution for industry.”
“The City of Hubbard is proud to serve as the host for this project,” added Mary Alderman, the Mayor of Hubbard, TX. “Like many communities in Texas and across the country, we’re facing growing concerns about water quality, aging infrastructure, and contamination. What’s so compelling about AirJoule® is that it produces pure, distilled, PFAS-free water right at the source. We believe it can be part of the long-term solution for communities and industries that need clean water without compromise.”
With a growing number of communities and industries in Texas facing structural water quality constraints, it is an important early market for AirJoule®. By generating water from air using any readily available low-grade waste heat, the AirJoule® platform offers a scalable and energy-efficient alternative that mitigates strain on groundwater and surface water resources.
Interest in developing geothermal in Texas is growing, with companies like Sage Geosystems, Bedrock Energy, and Exceed Geo Energy all working on early stage projects. In 2023, a collaborative study headed by Project Innerspace indicated that Texas is a prime area for geothermal development, in huge part because of the state’s rich oil and gas expertise.
