Demand of the Question
- Explain the concept of CCU
- Examine the potential of CCU in India
- Examine the challenges of CCU adoption
- Discuss policy measures required for large-scale adoption
What you wrote:
Carbon capture and utilisation (CCU) refers to technologies that capture Carbon dioxide (CO₂) emissions from industrial sources (eg: Steel, cement, fertilizers, power plants) and convert them into useful products such as fuels, chemicals, building materials, or synthetic aggregates, instead of releasing CO₂ into the atmosphere. Unlike Carbon Capture and Storage (CCS), CCU seeks value creation alongside mitigation.

Unlike Carbon Capture and Storage (CCS), CCU seeks value creation alongside mitigation.
Suggestions to improve:
- Could briefly contextualize with India's emissions profile (e.g., India emits ~2.9 billion tonnes of CO₂ annually, with industrial processes contributing ~30% of total emissions, making CCU relevant for meeting INDCs under the Paris Agreement).
What you wrote:
POTENTIAL FOR INDIA:
1. Decarbonising hard-to-abate Sectors: India's cement, steel and refining industries account for a large share of process emissions; CCU can reduce their carbon intensity without disrupting output.
2. Circular Carbon Economy: CO₂ can be converted into methanol, urea, polymers, or carbonates for construction, supporting "waste-to-wealth".
3. Energy Transition Synergy: Coupling CCU with green hydrogen enables production of e-fuels and sustainable aviation fuel, aiding net zero pathways.
4. Industrial competitiveness: Early adoption may help Indian exports meet carbon border adjustment mechanisms in global markets.

4. Industrial competitiveness: Early adoption may help Indian exports meet carbon border adjustment mechanisms in global markets.
Suggestions to improve:
- Can add emission intensity data (e.g., Indian cement industry emits ~550-600 kg CO₂ per tonne of cement; CCU could reduce this by 30-40% through carbon capture in clinker production)
- Could mention government initiatives like the National Hydrogen Mission enabling CCU integration with e-fuel production for aviation sector decarbonization
What you wrote:
CHALLENGES:
i) High Cost and Energy demand: Capture and conversion remain capital-intensive and may increase production costs unless powered by cheap renewables.
ii) Technology maturity: Many CCU pathways are at pilot scale; scalability and lifecycle climate benefits vary by product.
iii) Market limitations: Demand for CO₂-derived products (eg: chemicals, fuels) may be insufficient to absorb large volumes.
iv) Infrastructure gaps: CO₂ transport, hubs and storage/utilisation clusters are underdeveloped in India.
v) Regulatory uncertainty: Lack of standards on carbon accounting, product certification and liability.

Suggestions to improve:
- Could reference actual cost barriers (e.g., CCU capture costs range $50-100 per tonne CO₂ vs CCS at $40-80, making economic viability challenging without carbon pricing mechanisms)
- Can mention India's fragmented industrial clusters hindering co-location benefits for CCU infrastructure development
What you wrote:
POLICY MEASURES FOR LARGE-SCALE ADOPTION:
i) Targeted incentives: Viability gap funding, tax credits or carbon pricing to bridge cost differentials.
ii) R&D and pilot clusters: Public-private CCU hubs near industrial corridors (eg: refineries, cement belts).
iii) Standards and MRV: Lifecycle assessment protocols and certification for CO₂ derived products.
iv) Green hydrogen integration: Align CCU with national green hydrogen Mission to enable e-fuel markets.
v) Public Procurement: Preferential use of low-carbon cement/concrete in infrastructure projects.

Suggestions to improve:
- Can add reference to Production-Linked Incentive (PLI) schemes adaptation for CCU technologies in hard-to-abate sectors
- Could suggest establishing CCU-specific mandates under PAT (Perform, Achieve, Trade) scheme for energy-intensive industries
What you wrote:
Conclusion: CCU can complement renewables and efficiency in India's decarbonisation strategy, especially for heavy industry. Realising its promise requires cost reductions, robust carbon accounting, and coordinated industrial-energy policy support.

Suggestions to improve:
- Could link with SDG 13 (Climate Action) and SDG 9 (Industry, Innovation, Infrastructure), emphasizing India's leadership potential in developing cost-effective CCU models for the Global South
The answer systematically addresses all question demands with logical structure and relevant points. However, it needs more quantitative data, specific schemes/initiatives (National Hydrogen Mission mentioned but underutilized), and tighter integration with India's climate commitments to enhance depth and analytical quality.
