 With Us, The Way You Get Carbon Removal Can Make All The Difference

Humidity-Swing
Carbon Capture Technology

Critical Need

Arbon has developed reusable materials that capture CO₂ under dry conditions and release it when exposed to humidity. This innovation enables downstream utilization or sequestration of high-concentration CO₂.

Potential Impact

Arbon's two-year vision is to deploy multiple compact pilots nationwide.

Our ultimate goal is to achieve gigaton-scale CO₂ removal to significantly reduce atmospheric CO₂ and combat climate change.

 How Our Technology Works

Our sorbents capture CO₂ at ambient temperature and pressure when dry,
and release CO₂ when they are wet.

Ready to Capture CO₂ from air

02

Fully loaded with CO₂

03

Release CO₂ when wet

Arbon’s core humidity-swing technology uses only water. Our sorbents have exhibited remarkable stability and do not degrade even after 30,000 cycles.
Our technology has a high energy efficiency without consuming extra heat to regenerate materials, avoiding the high energy cost associated with other carbon capture industries.

The Challenge

Global CO₂ emissions exceed 36 Gt annually, according to the IEA. To limit warming to 1.5 °C, we must cut emissions in half by 2030 and reach net-zero by 2050. This requires both rapid decarbonization of current emitters and large-scale removal of CO₂ already in the atmosphere.

Our Solution

Arbon’s humidity-swing technology addresses both sides of this challenge. Our solution operates efficiently across DAC and point source capture. With proven performance in high-temperature, high-humidity, and impurities-rich environments, our system delivers fast CO₂ uptake and reliable operation in real-world industrial conditions.

Why Both Matter

Point source capture is critical for decarbonizing hard-to-abate industries like cement, steel, and aluminum production. DAC is the only viable method to remove the emissions accumulated since the Industrial Revolution. Our platform bridges both applications, providing a scalable, deployment-ready solution where others require separate technologies.

Annual Water Consumption in Arid Regions

Putting our low water usage in perspective. Water scarcity doesn’t limit our carbon capture potential. Even in arid regions where water is most precious, existing industrial water usage provides ample opportunity to deploy our humidity-swing technology at scale - proving that effective climate solutions can work within current resource constraints.

Here’s how our technology would perform across three water-scarce regions, demonstrating substantial CO₂ capture potential within existing industrial water usage.
