Capture That Pays Back
DOCC isn’t just technically viable — it’s financially compelling.

Built for Cost-Efficient Capture
Many carbon capture systems only make sense at scale — with megaton emitters, solvent towers, and massive infrastructure. DOCC was designed from the start to be cost-effective at small and mid-scale, where most industrial engines operate.
Levelized cost of capture: CAD 56–178 per ton CO₂
That’s lower than most amine systems and far below direct air capture (DAC), with no chemical handling, no thermal regeneration, and no permanent infrastructure.

Per-ton CO₂ capture cost drivers:
No chemical solvents
Lower OPEX
No thermal regeneration
Lower energy
Modular design
Lower CAPEX
CO₂ liquefaction
No post-treatment required
DOCC operates at 1.7–2.3 GJ per ton CO₂ — among the most efficient small-scale capture systems on the market.

In some scenarios, DOCC not only pays for itself — it reduces net electricity cost.
