Summary and Key Information

Core Content

The International Energy Agency (IEA) emphasizes the critical importance of Carbon Capture and Storage (CCS) in industrial applications for achieving significant emissions reductions and addressing climate change. Industrial sectors such as cement, iron and steel, chemicals, and refining account for one-fifth of global CO₂ emissions, and these emissions are expected to grow unless CCS is widely implemented. CCS is currently the only viable option for deep decarbonisation in these sectors, as energy efficiency improvements have limited potential to reduce emissions.

The report outlines the need for global action to advance CCS in industry, identifying key obstacles such as knowledge gaps, competitiveness concerns, and limited sector engagement. It also highlights the importance of a supportive policy environment, public-private collaboration, and international coordination to accelerate CCS deployment.

Main Viewpoints

• CCS is essential for decarbonising industrial sectors due to the high proportion of emissions that are inseparable from production processes.
• Industrial CCS can reduce the cost of climate mitigation by enabling low-cost emissions reductions and supporting the economic viability of low-carbon technologies.
• Early deployment in sectors like gas processing, hydrogen, and ethanol production is feasible and offers low-cost opportunities.
• Policies must be tailored to the specific technical and economic needs of each sector and address global competitiveness concerns.

Key Information

Why is CCS in industrial applications important?

• Industrial sectors contribute one-fifth of global CO₂ emissions and are expected to grow under current policies.
• CCS is the only option for deep emissions reductions in many industrial processes, especially those where CO₂ is unavoidable.
• CCS can break the link between economic growth and CO₂ emissions, as key materials like steel, cement, and chemicals are essential for low-carbon technologies and modern economies.

Current Status of CCS in Industrial Sectors

• Some sectors (e.g., gas processing, hydrogen, ethanol) have proven CCS technologies and commercial applications.
• Other sectors (e.g., steel, cement) lack sufficient demonstration projects and experience, making technical readiness and cost uncertainty major barriers.
• CO₂ capture in industrial applications is less advanced than in the power sector, particularly due to the variability of CO₂ sources and technical challenges.

Obstacles to Policy Action

• Knowledge gaps on costs and technical performance of CCS technologies.
• Competitiveness concerns due to increased production costs and regional policy fragmentation.
• Limited engagement of industrial sectors in CCS challenges such as public understanding and infrastructure development.

Recommended Global Actions

1. Commit public funds to pilot and demonstration projects in sectors like iron and steel and cement.
2. Scale up CCS projects step-by-step, prioritizing knowledge generation over immediate emissions reduction.
3. Incorporate CCS into forward-looking industrial strategies to attract private investment and ensure long-term viability.
4. Address competitiveness concerns with sector-specific policy instruments like feebate schemes and emissions standards.
5. Exploit synergies between sectors, especially with the power sector, to share infrastructure and reduce costs.
6. Involve all relevant stakeholders, including industry, governments, and international bodies, to reduce risks and increase confidence in CCS deployment.

Conclusion

• CCS in industrial applications could represent around half of global emission reductions by 2050.
• Early action is essential to ensure technological readiness and economic feasibility by 2030.
• Government support is crucial to overcome market failures and unlock private investment in CCS.

Key Figures and Projections

• One-quarter of global CO₂ emissions are from industrial sectors.
• Industrial CCS could achieve one-sixth of cumulative emissions reductions by 2050, with half from industrial applications.
• By 2050, one-third of steel production and one-quarter of cement production could be equipped with CCS.
• CO₂ capture in industrial applications is more cost-effective than in the power sector, due to high-purity CO₂ sources and existing commercial applications.

Policy Implications

• Policies must be designed to address technical, economic, and political challenges.
• International collaboration is necessary to align policy frameworks and reduce regional disparities.
• Investor confidence is critical for long-term deployment of CCS technologies.
• Public engagement and knowledge sharing are essential for acceptance and implementation of CCS.

Final Note

The report underscores that CCS is not just a technical solution, but a strategic necessity for achieving global climate targets and supporting economic growth. Timely and coordinated policy actions are required to drive innovation, reduce costs, and ensure the widespread deployment of CCS in industrial applications.
