Carbon Capture and Utilisation (CCU) in India (Completely Explained)

Context

Carbon Capture and Utilisation (CCU) technologies capture carbon dioxide from industrial emissions or directly from air and convert it into useful products such as fuels, chemicals, and construction materials. As India advances toward its net-zero target of 2070, CCU is emerging as a strategic tool for decarbonising hard-to-abate sectors while promoting a circular carbon economy.

Q1. What is Carbon Capture and Utilisation (CCU) and how is it different from CCS?

1. What is CCU?
   1. Captures CO₂ from industrial flue gases or ambient air.
   2. Converts captured CO₂ into value-added products (like Synthetic fuels, Chemicals, Polymers and Concrete and building materials)
2. Difference from Carbon Capture and Storage (CCS)?
   1. CCS stores CO₂ underground permanently whereas CCU reuses CO₂ within industrial supply chains.
   2. CCS focuses on sequestration; CCU focuses on economic reuse.
   3. CCU contributes to circular economy principles.

Q2. Why does India need CCU?

1. India is the third-largest global CO₂ emitter.
2. Major emissions from power, cement, steel, and chemicals.
3. These sectors are difficult to electrify fully.
4. Renewable energy alone cannot decarbonise industrial processes.
5. CCU helps reduce emissions without halting production.
6. Supports India’s net-zero target (2070).
7. Encourages circular low-carbon industrial ecosystems.
8. CCU addresses the gap between industrial growth and climate commitments.

Q3. What progress has India made in CCU development?

1. Policy and Institutional Support
   1. The Department of Science and Technology (DST) developed R&D roadmap.
   2. The Ministry of Petroleum and Natural Gas released a draft 2030 CCUS roadmap.
   3. Focus on pilot-scale demonstrations.
2. Industry-Led Initiatives
   1. Ambuja Cements piloting CO₂-to-fuel/material conversion.
   2. JK Cement developing CO₂-based concrete products.
   3. ORSL piloting Bio-CCU to convert biogenic CO₂ into bioalcohols and specialty chemicals.
3. India is in early-stage pilot implementation rather than large-scale deployment.

Q4. How are global economies advancing CCU?

1. European Union: Integrates CCU within the Circular Economy Action Plan. Promotes CO₂-to-material conversion strategies. Links CCU to sustainability taxonomy.
2. United States: Offers tax credits and subsidies. Public funding for industrial carbon conversion projects. Incentivises CO₂-derived fuel production.
3. United Arab Emirates: Integrates CCU with green hydrogen. Targets decarbonisation of heavy industry. Developing CO₂-to-chemicals hubs.
4. China: Scaling CCUS in coal-based power plants. Investing in CO₂ conversion to building materials. Rapid pilot-to-commercial transition approach.
5. Global experience highlights the importance of incentives and infrastructure.

Q5. What challenges constrain CCU expansion in India?

1. Economic Constraints: High energy and capture costs. CO₂-derived products face fossil-based price competition. Lack of carbon pricing reduces incentive.
2. Infrastructure Gaps: Need for industrial clusters near emission sources. Limited CO₂ transport pipelines. Inadequate integration with downstream industries.
3. Regulatory and Market Issues: Absence of clear carbon product standards. Lack of certification frameworks. Uncertain demand for CO₂-based materials.
4. CCU viability depends on policy-backed market creation.

Q6. What are the benefits and concerns associated with CCU?

1. Environmental and Economic Benefits
   1. Reduces industrial emissions.
   2. Creates new green value chains.
   3. Promotes circular economy.
   4. Encourages technological innovation.
   5. Enhances industrial competitiveness.
2. Environmental and Governance Concerns
   1. Risk of prolonging fossil fuel dependence.
   2. Lifecycle emissions may remain significant.
   3. High energy consumption if powered by fossil sources.
   4. Need for strict monitoring and verification.
3. CCU must complement, not replace, renewable energy expansion.

Q7. What safeguards and policy support are necessary for scaling CCU?

1. Carbon pricing or market-based incentives.
2. Viability gap funding for pilot projects.
3. Development of CO₂ transport and storage infrastructure.
4. Green hydrogen integration to lower lifecycle emissions.
5. National standards for CO₂-based products.
6. Monitoring and reporting frameworks to ensure real emission reduction.
7. Strong governance frameworks will determine long-term sustainability.

Conclusion

Carbon Capture and Utilisation represents a strategic bridge technology for India’s hard-to-abate industrial sectors. While offering potential for emissions reduction and industrial innovation, CCU requires economic incentives, regulatory clarity, and integration with renewable energy systems. Its success will depend on balancing climate ambition with industrial competitiveness within a structured policy ecosystem.
