Carbon Capture Utilization and Storage Funding for Decarbonization

Source:Indian Express ↗

Why It Matters

CCUS is increasingly recognized as an essential technology for global decarbonization, specifically for heavy industries. Government funding addresses the high capital costs associated with CCUS, making its development a crucial topic for GS3 Environment and Science & Technology.

Summary

The Government of India is set to invest Rs 20,000 crore over the next five years to advance Carbon Capture, Utilization, and Storage (CCUS) technologies. This substantial financial backing aims to significantly reduce carbon emissions from hard-to-abate sectors like steel and cement, making it a cornerstone of India's strategy to meet its net-zero emissions target by 2070.

Key Points

  • The Indian government plans to invest Rs 20,000 crore over five years to promote Carbon Capture, Utilization, and Storage (CCUS) technologies.
  • CCUS is vital for decarbonizing "hard-to-abate" industrial sectors such as steel, cement, and thermal power, where direct electrification is currently difficult.
  • The technology involves capturing CO2 emissions at the source and either utilizing them in industrial processes or storing them permanently underground.
  • This financial commitment is a strategic step towards fulfilling India's climate goals, particularly the target of achieving net-zero emissions by 2070.

Important Terms

Carbon Capture, Utilization, and Storage (CCUS)

Technologies that capture CO2 from industrial or power sources to be reused in products (like chemicals) or permanently stored underground in geological formations to prevent atmospheric release.

UPSC context

GS3: Environment & Science and Technology. Tests knowledge of emerging mitigation technologies and industrial emission reduction strategies.

Source
Hard-to-abate sectors

Industries like steel, cement, and chemicals where emissions result from chemical reactions or high-temperature heat requirements, making them technically and economically difficult to decarbonize through electrification alone.

UPSC context

GS3: Economy & Environment. Focuses on industrial policy and challenges in achieving net-zero targets.

Net Zero 2070

India's commitment, announced at COP26, to reach carbon neutrality by 2070, ensuring all greenhouse gas emissions are balanced by removal through carbon sinks or technology.

Panchamrita

The five-fold climate action strategy announced by India at COP26, including targets for non-fossil energy capacity, renewable energy share, emission reductions, and carbon intensity.

UPSC context

GS3: Environment. Tests awareness of India's official climate roadmap and Nationally Determined Contributions (NDCs).

Source
Decarbonization

The systematic process of reducing or eliminating carbon dioxide emissions from a country's economy, particularly in the energy, transportation, and industrial manufacturing sectors.

"CCUS technologies primarily capture historical CO2 directly from the atmosphere to reverse global warming."

Standard CCUS captures emissions at the source (industrial smokestacks) before release. Capturing ambient air is Direct Air Capture (DAC), a distinct and costlier technology.

Static Concepts Connected

Environment & Economy

Why are industries like cement and steel termed 'hard-to-abate'?

  • Chemical Process emissions: In cement manufacturing, the calcination of limestone intrinsically releases CO2 as a byproduct, independent of the fuel source used.
  • High Heat demand: These industries require extremely high temperatures historically achieved only through fossil fuels, making direct renewable electrification highly difficult.
  • Long-term lock-in: Capital-heavy industrial plants have multi-decade lifespans, causing infrastructure 'carbon lock-in' unless retrofitted with CCUS.
Geography & Environment

Where is captured carbon permanently stored geologically under CCUS?

  • Saline Aquifers: Deep underground porous rock formations filled with unpotable brine, offering the largest potential carbon storage capacity globally.
  • Depleted Oil/Gas Fields: Old fossil-fuel reservoirs where injected CO2 can be securely trapped, sometimes simultaneously aiding in Enhanced Oil Recovery (EOR).
  • Unmineable Coal Seams: Deep coal seams where CO2 is adsorbed, which is sometimes utilized for Enhanced Coal Bed Methane (ECBM) recovery.

Cross-Topic Patterns

  • CCUS & Circular Carbon Economy

    The 'U' in CCUS links directly to circular economy frameworks by converting captured industrial CO2 into value-added products like green urea, methanol, and sustainable building materials.

  • Green Hydrogen + CCUS synergies

    Decarbonizing heavy industry uses a dual approach: Green Hydrogen as a clean reducing agent to replace coking coal, and CCUS to capture unavoidable chemical emissions from legacy plants.

Expect a 2026 question contrasting industrial point-source CCUS with Direct Air Capture, emphasizing its role in hard-to-abate sectors.
