Avnos, Inc. – one of the world’s most innovative direct air capture technology startups, developing the novel Hybrid Direct Air Capture (HDAC™) approach, announced on November 6th it launched its first operational commercial pilot project in Bakersfield, California. 

The project has the capacity to capture approximately 30 tons of carbon dioxide from the atmosphere and produce 150 tons of water per year.

The pilot is developed in partnership with Southern California Gas Company (SoCalGas) and with funding support from the U.S. Department of Energy (DOE).

“This announcement marks a pivotal juncture for both our company and the industry… Removing legacy carbon dioxide emissions from the atmosphere is essential to addressing the negative effects of our changing climate, one of the most pressing issues of our lifetime. Doing so without further strain on our natural resources is something that the team at Avnos has worked tirelessly to achieve. We take a great deal of pride in launching this pilot, thereby proving the efficacy and scalability of our unique HDAC solution,” said Will Kain, Chief Executive Officer at Avnos. 

The proprietary Avnos HDAC technology represents a unique system that captures CO2 from the atmosphere while also producing water. It is capable of producing 5 tons of liquid distilled water per one ton of CO2 captured, as compared to 5-10 tons of water consumption per ton of CO2 captured as in other DAC approaches.

Capturing water from the air allows Avnos to leverage a first-of-a-kind moisture-swing CO2 adsorbent material, which in turn eliminates the need for heat input and reduces energy consumption by more than 50% as compared to other DAC technologies. 

Thus, Avnos revolutionizes the DAC space by not only capturing CO2 while producing water but also achieving substantial reductions per cost of removal per ton of CO2 which is ahead of the market. It is likely to near the $100 benchmark in the early 2030s. The atmospheric water extraction is a unique approach with intellectual property coming from the Pacific Northwest National Laboratory.

“Removing carbon dioxide from the atmosphere in a water and energy-efficient manner was a key reason for the early research into HDAC technology… It is exciting to see that initial idea come to life through the deployment of this HDAC demonstration system. The operational experience being gained is critical to scaling up HDAC technology for applications that can have a real impact in meeting net carbon emission reduction goals,” said Pete McGrail, retired Laboratory Fellow at PNNL. 

According to the company, Avnos has also joined four applications for DAC Hub grants from the Department of Energy and won all of them. Three of those projects the company will be taking part in are the Western Regional DAC Hub, the California Direct Air Capture Hub, and the Pelican-Gulf Coast Carbon Removal.

Back in July 2023, it also announced it secured $80 million in funding and multi-year strategic partnerships with the companies ConocoPhillips, JetBlue Technology Ventures, the corporate venture capital division of JetBlue, and Shell Ventures LLC, the US venture capital arm of Shell, to accelerate deployment of its technology.
