What is Carbon Capture, Utilization and Storage (CCUS)? What is the potential role of CCUS in tackling climate change?(Answer in 150 words)

Introduction

Carbon Capture, Utilization and Storage (CCUS) refers to a set of technologies that capture carbon dioxide (CO₂) emissions from sources such as power plants and heavy industries, and then either reuse (utilize) it in industrial processes or store it permanently in underground geological formations. According to the International Energy Agency (IEA) and IPCC, CCUS is an important technology for achieving global net-zero emissions by mid-century.

Body

Process of CCUS

• Carbon Capture: CO₂ is captured from industrial emissions (power plants, cement, steel industries).

• Utilization: Captured CO₂ is used in products such as chemicals, fuels, and enhanced oil recovery.

• Storage: CO₂ is injected deep underground in geological formations like depleted oil and gas fields.

Role of CCUS in Tackling Climate Change

• Reducing Industrial Emissions: Helps decarbonize hard-to-abate sectors such as steel, cement, and fertilizers.

• Supporting Net-Zero Goals: Complements renewable energy in achieving global climate targets.

• Negative Emissions Potential: Combined with bioenergy (BECCS), it can remove CO₂ from the atmosphere.

• Energy Transition Tool: Allows continued use of fossil fuels with reduced emissions during the transition phase.

Conclusion

Thus, CCUS can play a significant role in global climate mitigation by

reducing industrial emissions and enabling low-carbon energy systems.

However, its effectiveness depends on technological advancement, cost reduction,

and strong policy support.
