Humidity-Swing DAC Technology
Critical Need
Arbon has developed reusable materials capable of removing CO₂ directly from the air in a dry condition and releasing CO₂ with fast kinetics when materials become wet. This innovation holds immense significance as it offers a solution for utilizing or sequestering the released high concentrations of CO₂ downstream.
Potential Impact
Arbon’s two-year vision is to aggregate multiple pilots for CO₂ removal in urban environments. Each compact pilot device, occupying only a cubic meter, can eliminate one ton of CO₂ per day. Arbon’s ultimate goal is to implement these devices extensively, removing CO₂ at a gigaton scale, consequently reducing atmospheric CO₂ levels significantly and contributing to the alleviation of the climate crisis.
How our technology works
Our sorbents capture CO₂ from the air at ambient temperature
and release CO₂ when they are wet.
Stage 1. Dry condition
Our sorbent is ready to load CO₂ by utilizing alkali on the surface
Stage 2. CO₂ removal
Our sorbent is fully loaded with CO₂ in minutes
Stage 3. Introduce humidity
Our sorbent releases concentrated CO₂ immediately

Arbon’s core humidity-swing technology uses only water. Our sorbents have exhibited remarkable stability and do not degrade even after 10,000 cycles.
They possess a high energy efficiency without consuming extra heat to regenerate materials, avoiding the high energy cost associated with other DAC technologies.

Urgency
Today, the International Energy Agency (IEA) predicts that the annual global CO₂ emission is around 36 Gt.
By 2030, we need to reduce 50% of CO₂ emissions to the 2005 level to achieve the target of limiting the temperature increase to 1.5°C.
By 2050, achieving net-zero CO₂ emissions is essential to curb the trajectory of global warming.
Necessity
Direct Air Capture (DAC) coupled with sequestration is the sole solution to remove the CO₂ already in the atmosphere since the Industrial Revolution.
