How it works
Technology
Our DAC technology is designed for scale and fully tuned towards the renewable grid of the future.
Using electricity, water and salt, we capture CO2 from ambient air to produce a highly pure CO2 gas. The captured CO2 can be used for either permanent storage or as a precursor to CO2-negative chemicals.
3 steps
Absorb. Desorb. Repeat.
STEP 1 – ABSORPTION
Ambient air comes into contact with our basified sorbent. The CO2 is selectively absorbed by the sorbent.
)
STEP 2 – DESORPTION
The CO2-loaded sorbent is mixed with acid, releasing high-purity CO2 in a pH-swing reaction. The CO2 is is used for storage or utilization.
)
STEP 3 – REPEAT
Our proprietary Hydrolyzer regenerates acid and base for steps 1 and 2, using only (renewable) electricity.

THE STAR OF THE SHOW
The Phlair Hydrolyzer
Load-flexible
Compatible with behind-the-meter solar.
Our proprietary Hydrolyzer purely runs on renewable energy. It can be ramped up and down depending on the availability of clean (and cheap) electricity, acting as a chemical battery. The result: access to low cost of electricity, yielding low operating costs.
Scalable
Designed for scale. Building on existing supply chains.
Our Hydrolyzer combines two existing Hydrogen technologies into a new cell design. The cell architecture is designed to allow for industrial-sized stacks, and the components of this modular system are readily available and industry-proven, making the process highly scalable.
Energy-efficient
Energy is valuable. We use it sparingly.
Seperating CO2 from ambient air traditionally requires a lot of energy. With our key innovation, the Hydrolyzer, we have developed a highly efficient, electro-chemical sorbent regeneration. The result: 3x lower energy capture costs than thermal DAC approaches, yielding lower removal costs.
