DIRECT ANSWER: India's Decarbonization Strategy includes a crucial ₹20,000-Crore scheme focused on developing and deploying Carbon Capture, Utilisation, and Storage (CCUS) technologies across hard-to-abate industrial sectors. This financial commitment aims to reduce industrial emissions significantly, supporting India’s goal of achieving net-zero emissions by 2070, while creating a domestic CCUS market.
Why in News?
The Ministry of Power recently announced plans for a substantial financial allocation—approximately ₹20,000 crore—over the next five years, specifically targeting the promotion of indigenous Carbon Capture, Utilisation, and Storage (CCUS) technology deployment. This investment prioritizes industrial clusters like steel, cement, and fertilizer production, which currently lack cost-effective direct electrification pathways for emissions abatement.
What is the Concept / Issue?
Carbon Capture, Utilisation, and Storage (CCUS) involves a set of technologies that trap carbon dioxide (CO2) emissions from large stationary sources before they are released into the atmosphere. The captured CO2 is then either compressed and permanently stored deep underground in suitable geological formations (Storage component) or converted into usable products, such as synthetic fuels, building materials, or industrial chemicals (Utilisation component).
Why is this Issue Important?
- Strategic: Essential for meeting India's Nationally Determined Contributions (NDC) targets and the ambitious 2070 Net-Zero commitment, by addressing the approximately 15% of national emissions originating from hard-to-abate industrial processes.
- Economic: Stimulates green job creation, fosters domestic technological innovation, and potentially creates a new revenue stream through the utilization of captured carbon in high-value products, thereby improving industrial competitiveness.
- Geopolitical/Social: Enhances India’s energy security by allowing the continued use of fossil fuels (while mitigating emissions) during the transition, and bolsters its standing as a responsible global climate actor in multilateral forums.
Key Sectors / Dimensions Involved
- Dimension 1 (Industrial Decarbonization): Target sectors include high-emission industries like cement (process emissions), iron and steel, and thermal power generation, where CCUS offers one of the few viable deep decarbonization routes.
- Dimension 2 (Technological Development): Focus on R&D for reducing the high energy penalty associated with current capture technologies (e.g., amine scrubbing) and developing efficient conversion pathways for CO2 utilization in India’s specific industrial ecosystem.
- Dimension 3 (Market Creation and Policy): Establishing regulatory clarity for carbon storage liability, creating market-based incentives (e.g., competitive bidding, carbon pricing mechanisms), and funding infrastructure for CO2 transport pipelines.
What are the Challenges?
- High initial capital expenditure required for setting up capture facilities and the significant operational energy penalty, which increases the cost of production, making CCUS projects non-competitive without substantial subsidies.
- Uncertainty and lack of comprehensive data regarding the availability and long-term security of geological storage sites (saline aquifers, depleted oil/gas fields) across major industrial corridors in India.
- Absence of a robust, standardized regulatory framework, including clear liability assignment for leakages from permanent storage sites (CCS), which is critical for attracting necessary private investment.

How UPSC May Ask This Topic:
Despite significant financial allocations, Carbon Capture and Utilisation (CCUS) schemes face inherent economic and technological barriers in developing countries. Analyze the strategic importance of the ₹20,000 Crore CCUS scheme for India's decarbonization goals and critically examine the associated challenges for its large-scale deployment.
What is the Way Forward?
- Prioritize the establishment of regional Carbon Capture Hubs near industrial clusters and potential storage sites to share common transportation and storage infrastructure, achieving critical economies of scale.
- Implement targeted Viability Gap Funding (VGF) and long-term procurement assurances for CCUS-derived products (e.g., synthetic methanol) to de-risk early-stage projects and enhance commercial viability.
- Accelerate comprehensive geological mapping and pilot projects for CO2 storage in collaboration with global partners to establish a reliable, legally protected framework for deep storage liabilities and monitoring.
