Introduction
Deploying carbon sequestration at gigaton scale hinges on robust economics. Today’s projects cost $100–$200 per ton; to unlock global impact, we must drive that below $50. This article breaks down today’s cost structure, highlights levers for reduction, and examines the financing and market mechanisms that will fund a trillion-dollar industry.
1. Anatomy of Today’s Costs
Typical cost components for permanent sequestration:
- Capture: 60–70% of total. Includes DAC systems or point-source scrubbing, energy inputs, and reagents.
- Transport: 10–15%. Compression, pipelines or trucking, and leak-detection systems.
- Injection & Monitoring: 20–25%. Well drilling, caprock verification, seismic and soil-gas monitoring networks.
2. Drivers of Cost Reduction
Four key levers can compress the cost curve:
- Economies of Scale: Standardized, modular plants reduce unit CAPEX as volumes grow.
- Learning-By-Doing: Each new facility yields process improvements and optimized operations.
- Technology Innovation: Advances in sorbent materials, reactor designs, and AI-driven process control.
- Supply Chain Optimization: Localized manufacturing, mass production of key components, and integrated logistics.
3. Financing & Market Mechanisms
Securing capital at scale requires diversified funding and risk sharing:
- Carbon Credits & Auctions: Predictable forward revenue via credit markets or voluntary purchase agreements.
- Contracts for Difference (CfDs): Government-backed price floors that guarantee revenue above market rates.
- Green Bonds & Impact Funds: Low-cost debt financing directed toward climate infrastructure.
- Public-Private Partnerships: Co-investment and risk-sharing guarantees for early-stage deployments.
4. Global Cost Curve Projections
Recent models project a global learning curve slope of 20–25%, meaning each doubling of capacity cuts costs by ~20%. At current deployment rates, sub-$50/ton economics become feasible around 2035.

5. Barriers & Risk Mitigation
Key challenges must be managed to secure economic viability:
- Regulatory Uncertainty: Clear standards and liability frameworks are essential.
- Supply Chain Constraints: Scaling component manufacturing safely and sustainably.
- Price Volatility: Hedging mechanisms and stable off-take agreements.
- Public Acceptance: Transparent stakeholder engagement and benefits-sharing.
Conclusion
The economics of carbon sequestration will be the ultimate enabler of climate impact. By systematically reducing costs, de-risking investment, and leveraging market mechanisms, we can transform removal into a trillion-dollar industry that secures our planet’s future.
