Direct air capture, engineered for scale

We build hardware that makes carbon removal worth doing.

GigaDAC engineers filter-less direct air capture contactors and supplies liquefied, food-grade CO₂ to the industries that depend on it. National Science Foundation backed, independently reviewed, and building at commercial scale.

Engineering Value

Who we are

Direct air capture is an airflow problem. We designed for airflow first.

Founded by entrepreneurs and engineers, GigaDAC solves carbon removal through order-of-magnitude improvements in airflow efficiency and kinetic reactivity. Our contactor is hollow: air moves through open volume and meets an ultra-reactive mist, and our separators recover that mist at the lowest air resistance we have measured in any air capture system.

The result is lower capital cost, lower energy, and a design that scales by manufacturing rather than by construction.

How we bring value to you

Equipment, and the CO₂ it produces.

For DAC developers

Alto contactor

A filter-less contactor that integrates with any liquid sorbent and delivers more reactive contact at a fraction of the capital and operating cost of legacy air paths. Use it in a capture deployment, or to create a CO₂ feed stream for fuels and advanced materials.

For industrial buyers

Liquefied food-grade CO₂

The merchant CO₂ market has run tight and volatile because supply is a by-product of somebody else’s process running. Ours is not. We operate our own plants and contract the output directly, at below prevailing market rates.
