Avnos is redefining carbon removal with its groundbreaking Hybrid Direct Air Capture (HDAC) technology. Unlike traditional direct air capture (DAC) systems that rely on energy-intensive heat processes, Avnos' HDAC system removes both carbon dioxide (CO2) and water from the atmosphere simultaneously, producing distilled-quality water as a byproduct.
According to Will Kain, Avnos Founder & CEO, "We are the only water-positive company in direct air capture." This innovation makes Avnos’ technology more energy-efficient, cost-effective, and environmentally beneficial than conventional DAC solutions.
The company’s approach has attracted significant financial support, including $36 million in funding in 2024 and backing from the U.S. Department of Energy (DOE) and the U.S. Office of Naval Research.##How Avnos' HDAC Technology Works
Unlike conventional DAC systems, which require extreme heat to extract CO2, Avnos’ HDAC system uses a moisture-swing adsorbent.

This unique water-positive approach makes Avnos’ HDAC system a game-changer for carbon removal and sustainable water production.
Avnos is quickly scaling its operations. In Bakersfield, California, the company launched its first operational pilot project, Project Alpine. Following its success, Avnos is building a state-of-the-art research and development (R&D) facility in Bridgewater, New Jersey, set to become a hub for further innovation.
These efforts have earned Avnos a semifinalist position in the DOE’s Carbon Dioxide Removal Purchase Pilot Prize. The company is also part of four DOE DAC hubs in Louisiana, Illinois, and the Bakersfield region, further cementing its role in the future of carbon capture.
One of the biggest challenges for DAC companies is making carbon removal cost-effective. Most DAC systems today struggle to reach the $100 per ton CO2 removal cost target, a benchmark set by the U.S. government for scalable carbon capture solutions.
Avnos, however, has a clear path to achieving this goal.

Unlike traditional DAC systems, which work best in specific conditions, Avnos' HDAC technology can be deployed in most climates.
Avnos is focused on commercializing HDAC technology and expanding its footprint globally. The company is:
By continuing to refine and expand HDAC, Avnos aims to solidify its place as the leader in carbon removal and water-positive DAC technology.
With its patented hybrid approach, A*vnos is tackling two environmental challenges at once—carbon removal and water scarcity*. As global efforts to combat climate change intensify, companies like Avnos are proving that innovative technology can make carbon capture both practical and sustainable.
As Will Kain puts it, "We think that 2025 will be a big year of commercial maturation for us... deploying more demo and pilot units, maturing our supply chain, and building out those commercial relationships." With its strong partnerships and groundbreaking technology, Avnos is well on its way to leading the next phase of the carbon removal industry.
