From bench-scale to research pilots to commercial products.

Four years of iterative process engineering and over 4,000 hours of testing across units in Austria. Soon to be TRL-8 in Canada.

Core R&D

Fixed bed, fluidization and decoupled process - tested as TRL-4 lab prototypes.

Pilot in Austria

TRL-6 validation, first continuous field operation.

Kelvin POD — Austria

4,000+ hours logged across -10°C to 40°C conditions.

Kelvin Tower — Canada

TRL-8 deployment, operational in 2026.

Industry leading DAC OEM technology

Decoupled architecture

Adsorption and desorption run in distinct units for continuous CO₂.

Ultra-low energy demand

Regenerates at 80°C, ~1,800 kWh/ton.

Modular & manufacturable

Plug-and-play units with off the shelf parts.

Proven & flexible

Over 4,000 hours tested across -10°C to 40°C.

"DACLab's low-temperature, low-energy design addresses key barriers to scalable direct air capture. This is an important step as the industry moves from pilots to commercial deployment."

Dr. Klaus Lackner — Advisor to DACLab, pioneer in DAC. Developed in partnership with TU Wien.
