As someone deeply concerned about climate change and its impact on our planet, I've been closely following the development of various technologies aimed at reducing greenhouse gas emissions.
One such technology that has caught my attention is Carbon Capture and Storage (CCS). With India being one of the world's largest emitters of greenhouse gases, it's encouraging to see the country actively exploring and implementing CCS to mitigate its carbon footprint.
In this comprehensive guide, I want to share with you what I've learned about Carbon Capture and Storage India, its significance, current status, and prospects.
Understanding these aspects can help us appreciate the efforts being made and the potential of CCS in our fight against climate change.
What is Carbon Capture and Storage?
Carbon Capture and Storage (CCS) is a technology designed to reduce carbon dioxide (CO2) emissions from industrial and energy-related sources.
The process involves capturing CO2 at its emission source, transporting it to a storage location, and securely storing it underground to prevent it from entering the atmosphere.
CCS is seen as a vital tool for mitigating climate change by reducing the amount of CO2, a major greenhouse gas, released into the environment.
Components of CCS
- Capture: The first step involves capturing CO2 from power plants, industrial processes, or directly from the air. Various methods such as pre-combustion, post-combustion, and oxy-fuel combustion capture are employed.
- Transport: Once captured, CO2 is transported via pipelines, ships, or other means to the storage site.
- Storage: The final step is storing the captured CO2 in geological formations, such as depleted oil and gas fields or deep saline aquifers. These storage sites are chosen for their ability to securely contain CO2 for long periods.
The Importance of Carbon Capture and Storage India
India's Emission Landscape
India is the third-largest emitter of CO2 globally, following China and the United States.
The country's rapid economic growth, industrialization, and reliance on coal for energy contribute significantly to its greenhouse gas emissions.
To meet its climate commitments under the Paris Agreement, India must explore all possible avenues for emission reduction, including the adoption of Carbon Capture and Storage.
CCS and India's Climate Goals
India has set ambitious targets to reduce its carbon footprint. The nation aims to achieve a 33-35% reduction in emission intensity by 2030, relative to 2005 levels, and increase the share of non-fossil fuel-based energy capacity to 40%.
Implementing Carbon Capture and Storage India can play a pivotal role in achieving these targets by mitigating emissions from hard-to-abate sectors such as steel, cement, and power generation.
