Carbon Capture Cost Calculator

About the Carbon Capture Cost Calculator

Engineered carbon removal technologies — including Carbon Capture and Storage (CCS), Direct Air Capture (DAC), and Bioenergy with CCS (BECCS) — are essential components of net-zero pathways. Current costs range from $50–100/tonne for industrial CCS to $400–1,000/tonne for direct air capture from ambient air.

This Carbon Capture Cost Calculator estimates the total cost of a carbon capture project. Enter the amount of CO2 to be captured and the technology-specific cost per tonne. The calculator helps compare technologies and budget for removal at various scales.

As the 45Q tax credit in the U.S. now offers up to $180/tonne for DAC and $85/tonne for CCS with geological storage, these technologies are becoming increasingly financially viable at scale.

This measurement provides a critical foundation for energy auditing and sustainability reporting, helping organizations meet regulatory requirements and voluntary environmental commitments. Integrating this calculation into regular energy reviews ensures that conservation strategies are grounded in measured data rather than assumptions about building performance and usage patterns.

When This Page Helps

Carbon removal is essential for net zero but expensive. This calculator helps organizations budget for CCS/DAC projects, compare technology costs, and evaluate the impact of incentives like the 45Q tax credit. Regular monitoring of this value helps energy teams detect usage anomalies early and address equipment malfunctions or operational issues before they drive utility costs higher.

How to Use the Inputs

1. Enter the amount of CO2 to capture/remove in tonnes per year.
2. Enter the cost per tonne for your chosen technology.
3. Optionally enter a tax credit or incentive per tonne.
4. View gross cost, net cost after incentives, and comparison.

Example Calculation

Tips & Best Practices

• Industrial CCS ($50–100/t) is much cheaper than DAC ($400–1,000/t) but requires point sources.
• The 45Q credit offers $85/t for CCS and $180/t for DAC with geological storage.
• DAC costs are expected to fall below $200/t by 2035 with scale and innovation.
• BECCS combines biomass energy with carbon capture for potential "negative emissions."
• Geological storage in saline aquifers can hold billions of tonnes of CO2 permanently.
• Consider CO2 utilization pathways (concrete, fuels, chemicals) for partial cost recovery.

The Scale of the Carbon Removal Challenge

Meeting climate targets requires removing billions of tonnes of CO2 per year by mid-century. Current engineered removal capacity is a tiny fraction of this need. Governments and companies are investing to close the gap through DAC hubs, CCS infrastructure, and advance market commitments.

Technology Comparison

CCS is the lowest-cost option but only works at point sources. DAC can be deployed anywhere but costs 5–10× more. BECCS offers negative emissions from biomass but raises land-use concerns. Enhanced weathering spreads minerals that absorb CO2 but is early-stage. Each technology has a role.

The Business Case

With 45Q credits, IRA incentives, and corporate advance purchases (Frontier, Microsoft), carbon removal is becoming a business opportunity. Early movers are securing storage permits, technology partnerships, and offtake agreements that will be valuable as demand grows.

Frequently Asked Questions

• What is Direct Air Capture (DAC)?

  DAC uses chemical processes to capture CO2 directly from ambient air. Companies like Climeworks, Carbon Engineering, and Heirloom are building DAC facilities. The captured CO2 can be stored underground or used in products. Costs are currently $400–1,000/tonne but falling.

• What is CCS?

  Carbon Capture and Storage captures CO2 from industrial point sources (power plants, cement plants, steel mills) and injects it into geological formations for permanent storage. Costs are $50–100/tonne, making it the most affordable form of engineered carbon capture.

• What is the 45Q tax credit?

  The U.S. 45Q tax credit (expanded by the IRA) provides $85/tonne for CO2 captured and stored geologically from point sources, and $180/tonne for DAC with geological storage. This makes many projects economically viable.

• How permanent is geological storage?

  CO2 injected into deep saline aquifers or depleted oil/gas reservoirs is considered permanent on geological timescales (thousands to millions of years). Well-characterized storage sites with proper monitoring have very low leakage risk (<0.1% per millennium).

• Will DAC costs come down?

  Yes. Most projections show DAC costs falling to $100–200/tonne by 2040–2050 with deployment at scale, learning-by-doing, and cheap clean energy. Government procurement programs (DOE's CDR hub) are accelerating this trajectory.

• How much CDR is needed globally?

  IPCC scenarios require 5–15 billion tonnes of CO2 removal per year by 2050 for 1.5°C pathways. Current CDR capacity is under 1 million tonnes/year. A massive scale-up of both nature-based and engineered removal is needed.
