Coal-fired power generation plays a pivotal role in meeting the country’s growing energy demand and ensuring energy security. India is heavily reliant on coal for electricity generation, with coal-fired power plants accounting for a significant portion of the country’s energy mix. While coal-fired power generation has played a crucial role in powering India’s economic growth and development, it also presents significant challenges that must be addressed to safeguard the environment and public health.

One of the foremost challenges associated with coal-fired power generation in India is its environmental impact. The combustion of coal releases a plethora of pollutants, including carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter (PM), and mercury, contributing to air pollution, acid rain, smog formation, and respiratory illnesses. India is home to some of the most polluted cities in the world, with air pollution levels far exceeding the limits recommended by the World Health Organization (WHO). The reliance on coal-fired power generation exacerbates air pollution, posing significant risks to public health and environmental sustainability.

Furthermore, coal mining operations in India often entail environmental degradation, habitat destruction, and displacement of communities, further exacerbating the negative impacts of coal-fired power generation. The extraction, transportation, and combustion of coal also contribute to water pollution, soil contamination, and deforestation, undermining the integrity of ecosystems and jeopardizing biodiversity.

In addition to its environmental challenges, coal-fired power generation in India faces economic pressures and technological constraints. The economics of coal-fired power generation are increasingly challenged by the declining costs of renewable energy technologies such as solar and wind. Rapid advancements in renewable energy deployment and falling prices of solar and wind power have made these technologies more cost-competitive with coal, posing a threat to the financial viability of coal-fired power plants.

Despite these challenges, coal-fired power generation continues to play a critical role in India’s energy security and electrification efforts, particularly in remote and underserved areas where access to reliable electricity remains limited. Coal-fired power plants provide baseload power, ensuring grid stability and meeting peak demand, thereby contributing to energy security and economic development.

However, the imperative to reduce greenhouse gas emissions and combat climate change necessitates a transition away from coal towards cleaner and more sustainable energy sources. The Indian government has set ambitious targets for renewable energy deployment, including the installation of 450 gigawatts (GW) of renewable energy capacity by 2030, as part of its commitment to the Paris Agreement.

In conclusion, while coal-fired power generation continues to play a crucial role in India’s energy landscape, it also presents significant challenges that must be addressed to mitigate its environmental and health impacts. The imperative to reduce greenhouse gas emissions and transition to a more sustainable energy future requires concerted efforts to accelerate the deployment of renewable energy, improve energy efficiency, and explore innovative solutions such as carbon capture and storage (CCS). By embracing clean energy technologies and adopting a holistic approach to energy planning, India can achieve its twin goals of energy security and environmental sustainability, ensuring a brighter and healthier future for all.

Unveiling Carbon Capture and Storage (CCS): A Game-Changer in the Fight Against Climate Change

In the global quest to mitigate climate change and transition to a low-carbon future, carbon capture and storage (CCS) technology has emerged as a critical tool for reducing greenhouse gas emissions. CCS offers a promising solution for capturing carbon dioxide (CO2) emissions from industrial processes and power plants, transporting them to storage sites, and permanently sequestering them underground. In this introduction, we delve into the fundamentals of CCS technology and its potential role in addressing one of the most pressing challenges of our time: climate change.

Understanding Carbon Capture and Storage (CCS):

At its core, CCS technology involves three main steps: capture, transportation, and storage. In the capture phase, CO2 emissions are captured from industrial flue gases or power plant emissions using various capture technologies such as post-combustion, pre-combustion, or oxy-fuel combustion. These technologies utilize solvents, sorbents, or membranes to selectively capture CO2 while allowing other gases to pass through.

Once captured, the CO2 is compressed and transported via pipelines, ships, or trucks to suitable storage sites for injection underground. These storage sites typically include deep geological formations such as saline aquifers, depleted oil and gas reservoirs, or unmineable coal seams. The CO2 is then injected into these formations, where it is trapped and stored securely over geological timescales through mechanisms such as mineralization, dissolution, and structural trapping.

The Potential Role of CCS in Mitigating Climate Change:

CCS technology has the potential to play a pivotal role in mitigating climate change by significantly reducing CO2 emissions from major point sources such as power plants, cement factories, and industrial facilities. By capturing CO2 emissions before they are released into the atmosphere, CCS helps prevent the accumulation of greenhouse gases and the associated warming of the planet.

One of the key advantages of CCS is its ability to address emissions from existing infrastructure, particularly in sectors that are difficult to decarbonize using renewable energy alone. For example, CCS can be retrofitted to existing coal-fired power plants, allowing them to continue operating while reducing their carbon footprint. This is particularly relevant in countries like India and China, where coal remains a dominant source of electricity generation.

Moreover, CCS technology can facilitate the transition to a carbon-neutral or even carbon-negative energy system by enabling the removal of CO2 from the atmosphere through direct air capture and bioenergy with CCS (BECCS). These approaches have the potential to offset remaining emissions from sectors that are challenging to decarbonize and achieve net-zero emissions on a global scale.

As the world grapples with the urgent need to reduce greenhouse gas emissions and limit global warming, carbon capture and storage (CCS) technology offers a beacon of hope. By capturing and storing CO2 emissions from industrial processes and power plants, CCS has the potential to significantly reduce our carbon footprint and mitigate the impacts of climate change. However, realizing the full potential of CCS will require concerted efforts from governments, industries, and society as a whole to scale up deployment, drive innovation, and overcome technical, economic, and regulatory barriers. In the article to follow, we will explore the current state of CCS technology, its applications across various sectors, and the challenges and opportunities that lie ahead in the journey towards a sustainable and resilient future.

Some Common Geologically suitable Carbon Storage

The most geologically suitable sites for carbon storage, also known as carbon capture and storage (CCS) sites, typically possess specific characteristics that are conducive to safe and effective CO2 storage. Here are some of the most favorable geological formations for carbon storage:

Deep Saline Aquifers:

Deep saline aquifers are porous and permeable rock formations located deep underground, typically several thousand feet below the surface.
These formations consist of porous rock layers saturated with saline (salty) water, providing ample storage capacity for injected CO2.
The overlying impermeable rock layers act as seals, trapping the injected CO2 and preventing its upward migration.

2. Depleted Oil and Gas Reservoirs:

Depleted oil and gas reservoirs are geological formations that have been previously exploited for hydrocarbon extraction but are no longer economically viable.
These formations often possess significant porosity and permeability, making them suitable candidates for CO2 storage.
The residual oil or gas within these reservoirs can help displace and trap the injected CO2, enhancing storage efficiency.

3. Unmineable Coal Seams:

Unmineable coal seams are coal deposits that are economically unfeasible to extract due to various factors such as depth, thickness, or low-quality coal.
Coal seams can adsorb CO2 molecules onto their surfaces, providing a mechanism for CO2 storage through a process known as enhanced coal bed methane recovery (ECBM).
The injected CO2 displaces methane (CH4) from the coal seams, which can be extracted and utilized as a valuable energy resource.

4. Basalt Formations:

Basalt formations are volcanic rock formations with high porosity and extensive fracture networks.
Basalt has the capacity to chemically react with injected CO2 through mineral carbonation, converting CO2 into stable carbonate minerals over time.
This process, known as mineral trapping, offers a long-term and permanent storage solution for CO2.

5. Enhanced Oil Recovery (EOR) Sites:

Some oil reservoirs can be used for both enhanced oil recovery (EOR) and CO2 storage simultaneously.
CO2 injection into oil reservoirs can enhance oil recovery by reducing the viscosity of the oil and increasing reservoir pressure.
The injected CO2 can then be stored permanently within the reservoir after the EOR process is complete.

When assessing the suitability of geological formations for carbon storage, factors such as porosity, permeability, sealing capacity, depth, and proximity to emission sources are considered. Conducting thorough site characterization and risk assessments is essential to ensure the safety, effectiveness, and long-term integrity of CO2 storage operations.

Role of Geophysical Technologies

Seismic Survey:

Seismic surveys play a crucial role in carbon capture and storage (CCS) projects by providing valuable information about subsurface geology, reservoir characteristics, and the integrity of storage formations. Here’s how seismic surveys are used in CCS:

Site Characterization: Before implementing a CCS project, seismic surveys are conducted to characterize potential storage sites. These surveys use sound waves to create images of underground rock formations, helping identify suitable geological formations for CO2 storage, such as deep saline aquifers, depleted oil and gas reservoirs, or coal seams.
Reservoir Monitoring: Once a storage site is selected and CO2 injection begins, seismic monitoring is used to track the movement and behavior of injected CO2 within the subsurface reservoir. By periodically conducting seismic surveys, operators can assess CO2 plume migration, reservoir pressure changes, and potential leakage pathways, ensuring the long-term integrity and containment of stored CO2.
Leakage Detection: Seismic surveys are also employed to detect and monitor potential CO2 leakage from storage formations. By comparing baseline seismic data with subsequent surveys, any anomalies or changes in subsurface structure or fluid movement can be identified, indicating possible leakage pathways or integrity issues that require remediation.
Injection Well Placement: Seismic data assists in optimizing the placement of CO2 injection wells within storage formations, maximizing CO2 storage capacity and distribution while minimizing operational risks and costs. Detailed subsurface imaging helps identify favorable injection zones with suitable porosity and permeability for efficient CO2 injection and storage.
Risk Assessment and Mitigation: Seismic surveys aid in assessing geological risks associated with CCS projects, such as fault zones, fractures, or geological hazards that may affect storage integrity or induce seismic activity. This information enables operators to implement risk mitigation measures and ensure safe and secure CO2 storage operations.

Overall, seismic surveys provide critical insights into subsurface geology and reservoir behavior, facilitating the planning, implementation, and monitoring of CCS projects. By leveraging advanced seismic imaging techniques and interpretation methods, operators can optimize CO2 storage operations, enhance reservoir management, and mitigate environmental risks associated with CCS.
