Technology

Pushing the boundaries of airflow and reactivity.

Decades of aerospace and chemical engineering experience, refined into a contactor that removes the cost centers holding direct air capture back.

Engineering Value

Our technology

Deep experience refined into powerful technology.

We have turned decades of hard-earned engineering knowledge into a system designed for scale rather than demonstration. The contactor is hollow, the air path is open, and every design decision follows from treating carbon removal as an airflow problem first.

GigaDAC contactor system
  • AirflowAn aerospace-inspired airflow system engineered to optimize circulation and the efficiency of CO₂ capture.
  • No filtersRemoving bulky filter media cuts airflow resistance, and with it the fan energy you pay on every cubic meter.
  • KineticsSprayed solvent delivers rapid CO₂ kinetics, accelerating both absorption and regeneration.
  • ModularityA modular architecture supporting flexible deployment and straightforward scaling.
  • CostTargeting a capture cost under $100 per ton, so the economics work at scale rather than at subsidy.

Technology leadership

Four decisions that shape the whole system.

Aerospace-engineered airflow

A spray-based solvent system with no filter media in the air path, which drops airflow resistance and improves system efficiency across the board.

  • Optimized ducting and engineered flow paths reduce air resistance.
  • Lower pressure drop enables higher airflow without additional energy input.
  • Increased reactivity opens the door to lower-energy solvent regeneration.
Airflow design

Faster kinetics through a thin gas-phase boundary layer

Fine droplets present an extremely thin gas-phase boundary layer to the incoming air. Because that layer is the denominator in a diffusion-limited system, thinning it raises the absorption rate directly.

  • An order of magnitude thinner than conventional contacting.
  • Higher rates make milder, lower-energy chemistries viable.
  • Lower thermal input drives down energy consumption and operating cost.

Flux across the gas film scales as (c − cᵢ) ÷ δ. Thinning the layer raises the rate directly. Interfacial concentration cᵢ is finite, set by solvent back-pressure.

Modular, built for gigaton-scale

The system is purpose-built for replication rather than for one-off construction, so capacity is added by manufacturing units instead of commissioning bespoke plants.

  • Units engineered for quick deployment across varied geographies.
  • Plug-and-play architecture with minimal on-site customization.
  • Scales from kiloton commodity deployments to multi-megaton removal.

Regeneration

Energy-efficient regeneration

Low-pressure airflow and a richer solvent loading reduce the regeneration energy required, which is where the majority of operating cost sits in any liquid-sorbent system.

  • Lower thermal input requirements reduce energy consumption and cost.
  • Pairs with conventional solvent strippers or advanced electrochemical regeneration.
  • Independently modeled by a third-party engineering firm.
