Carbon Capture Pathways for Industrial Clusters
Comparing point-source and DAC pathways at industrial corridors, with cost and readiness signals.
Carbon capture comes in two structurally different shapes: post-combustion or pre-combustion capture at an industrial point-source, and direct air capture (DAC) from atmospheric CO2. They have very different cost structures, different methodology pathways, and different bankability profiles. Reading them correctly matters.
Point-source capture is closer to commercial
Point-source capture from refining, petrochemical, cement, and power flue gas streams is at higher concentration and lower cost than DAC. Capture cost ranges in the $40-100 per tonne band are achievable at scale with existing technology. The capture revenue is typically structured as Capture-as-a-Service paid by the industrial host, complemented by carbon credit revenue where the CO2 is permanently sequestered or utilized in qualifying ways.
DAC is structurally more expensive but unlocks premium credits
DAC operates at atmospheric concentration of 420 ppm, which translates structurally into higher capture cost — $200-600 per tonne under most current technology assumptions. The economic case rests on premium CDR credit pricing from buyers (Microsoft, Frontier coalition, others) where the engineered-removal attribute commands a premium over avoidance credits. DAC economics improve sharply with cheap renewable electricity, which is the Saudi advantage.
Phasing both pathways captures both opportunities
A staged deployment — point-source for cash-flow generation early, DAC for premium credit positioning later — captures both pathways without requiring the project to choose between them. The capital structure and methodology selection at each stage are different; the platform decision-support work is to track both readiness pictures separately.
Point-source and DAC are complementary, not substitutes. Saudi industrial corridors with access to both industrial CO2 sources and abundant renewable electricity are uniquely positioned to host both pathways in phased structures.
This insight is a summary view based on publicly available information and Renewable Vision's working perspective on the Saudi and GCC low-carbon transition. It is not investment, legal, or technical advice. References to methodology, market structure, and offtake economics are indicative and subject to project-level validation.
