Carbon Capture and Storage: Removing Carbon Dioxide from the Atmosphere
In the global fight against climate change, reducing carbon dioxide (CO₂) emissions is essential. The burning of fossil fuels, industrial processes, and deforestation have led to a sharp increase in atmospheric CO₂ levels, contributing to global warming. While renewable energy sources and energy efficiency are key strategies for reducing emissions, they alone cannot address all the carbon that has already been released into the atmosphere. This is where carbon capture and storage (CCS) comes into play.
Carbon capture and storage is a technology designed to remove CO₂ from the atmosphere, capturing it at its source or extracting it from the air, and then storing it deep underground or utilizing it in industrial processes. CCS offers a promising solution to help industries meet climate targets, reduce emissions, and mitigate the effects of climate change.
In this comprehensive article, we will explore what CCS is, how it works, its role in combating climate change, the current state of CCS technology, and the challenges it faces in widespread adoption.
The Urgency of Carbon Dioxide Removal
Climate change is one of the greatest challenges humanity faces, and the role of carbon dioxide in this crisis is well-established. CO₂ is the most prevalent greenhouse gas (GHG), contributing around 76% of global GHG emissions. The rise in CO₂ levels due to human activities has been linked to increasing global temperatures, more frequent extreme weather events, rising sea levels, and disruption of ecosystems.
Efforts to reduce emissions through renewable energy adoption, energy efficiency, and sustainable practices are crucial, but they are not enough to prevent further climate damage. According to the Intergovernmental Panel on Climate Change (IPCC), meeting the Paris Agreement goal of limiting global warming to 1.5°C above pre-industrial levels will require large-scale removal of CO₂ from the atmosphere in addition to reducing emissions.
This is where CCS becomes an essential component of a broader climate strategy. By capturing and storing carbon, we can not only reduce emissions from industrial processes but also potentially reverse some of the damage by removing CO₂ that has already accumulated in the atmosphere.
What is Carbon Capture and Storage (CCS)?
Carbon capture and storage (CCS) refers to a set of technologies designed to capture carbon dioxide emissions from large sources such as power plants, factories, and other industrial processes, and then transport and store it in a way that prevents it from entering the atmosphere. CCS can be applied to power generation, cement production, steel manufacturing, and other energy-intensive industries that contribute significantly to global CO₂ emissions.
CCS involves three primary steps:
- Capture: CO₂ is separated from other gases at the point of emission, either through chemical or physical processes.
- Transport: Once captured, the CO₂ is compressed and transported via pipelines, ships, or other methods to a storage site.
- Storage: The captured CO₂ is injected into deep underground geological formations, such as depleted oil and gas reservoirs, deep saline formations, or unmineable coal seams, where it is securely stored for long periods.
In some cases, captured CO₂ can also be utilized in industrial processes, such as enhanced oil recovery (EOR) or as a raw material in the production of building materials, chemicals, and synthetic fuels. This is known as carbon capture, utilization, and storage (CCUS).
The Three Phases of Carbon Capture and Storage
1. Carbon Capture
The first and most critical step in CCS is the capture of CO₂. There are three primary methods for capturing carbon
- Post-Combustion Capture: This process captures CO₂ after fossil fuels (such as coal, oil, or natural gas) have been burned. The flue gas is treated with a solvent that absorbs CO₂, which is then separated and compressed for transport. This method is commonly used in power plants and industrial facilities because it can be retrofitted to existing systems.
- Pre-Combustion Capture: In this method, CO₂ is captured before the fuel is burned. Fossil fuels are partially oxidized, producing a mixture of hydrogen and CO₂. The CO₂ is separated, leaving hydrogen to be used as a clean-burning fuel. Pre-combustion capture is more efficient than post-combustion capture but requires significant modifications to power plants and other facilities.
- Oxyfuel Combustion: In oxyfuel combustion, fossil fuels are burned in pure oxygen instead of air, resulting in a flue gas that is mostly CO₂ and water vapor. The water vapor is condensed, leaving nearly pure CO₂, which is easier to capture and compress. Oxyfuel combustion is still in the experimental stage, but it offers promising efficiency gains.
2. CO₂ TransportOnce CO₂ is captured, it needs to be transported to a storage site. Most CO₂ is transported via pipelines, which are considered the most cost-effective and efficient method for large-scale transport. In some cases, CO₂ can also be transported by ship or tanker, especially for offshore storage sites or regions without pipeline infrastructure.
Transporting CO₂ is not without its challenges. Pipelines need to be carefully designed and monitored to prevent leaks, and safety regulations must be followed to avoid accidents. However, there is extensive experience in transporting CO₂, particularly in the oil and gas industry, where CO₂ pipelines have been used for decades in enhanced oil recovery.
3. Carbon StorageThe final step in the CCS process is the storage of captured CO₂ in secure geological formations. Once injected deep underground, the CO₂ is trapped by a combination of physical and chemical processes, preventing it from leaking back into the atmosphere. The most common types of storage sites include:
- Depleted Oil and Gas Reservoirs: These reservoirs have held hydrocarbons for millions of years, making them well-suited for CO₂ storage. The infrastructure for drilling and monitoring already exists, which can reduce costs. Additionally, injecting CO₂ into oil fields can be used for enhanced oil recovery, increasing oil production.
- Deep Saline Formations: These are porous rock formations filled with salty water located deep underground. They are widely distributed and have a large potential storage capacity. However, they require more extensive monitoring and research to ensure long-term safety and stability.
- Unmineable Coal Seams: In some cases, CO₂ can be injected into coal seams that are too deep or inaccessible for mining. The CO₂ is absorbed by the coal, which can also release methane gas that can be captured and used as a fuel source.
The Role of CCS in Combating Climate Change
Carbon capture and storage is considered one of the most effective technologies for reducing CO₂ emissions from industries that are difficult to decarbonize. Sectors such as cement, steel, and chemical production are essential to the global economy, but they are also responsible for a significant share of emissions. CCS can help these industries meet climate targets while continuing to operate and produce essential goods.
According to the International Energy Agency (IEA), CCS could account for nearly 15% of the cumulative emissions reductions needed by 2070 to limit global temperature rise to 1.5°C. CCS is particularly important in scenarios where emissions cannot be avoided, such as in industrial processes, and it provides a pathway to achieving net-zero emissions.
In addition to reducing emissions, CCS can also be used to remove carbon that is already in the atmosphere. This is known as negative emissions or direct air capture (DAC). While still in the early stages of development, DAC has the potential to be a powerful tool in mitigating climate change, especially in sectors where emissions are difficult to eliminate.
The Current State of Carbon Capture and Storage Technology
While CCS has been around for decades, it is still in the early stages of commercial deployment. A handful of large-scale CCS projects are currently in operation, capturing millions of tons of CO₂ each year. However, the technology has yet to achieve widespread adoption due to several barriers, including cost, regulatory challenges, and public perception.
CCS Projects Around the World
There are currently around 27 large-scale CCS projects in operation worldwide, with several more in various stages of development. Some notable projects include:
- Boundary Dam (Canada): One of the first commercial CCS projects in the world, Boundary Dam captures CO₂ from a coal-fired power plant and uses it for enhanced oil recovery.
- Gorgon Project (Australia): The Gorgon Project captures CO₂ from natural gas processing and stores it in a deep saline formation under Barrow Island. It is one of the largest CCS projects in the world.
- Petra Nova (USA): Located in Texas, Petra Nova was the largest post-combustion CCS project in the world, capturing CO₂ from a coal-fired power plant. However, it has been offline since 2020 due to low oil prices and operational challenges.
- Norwegian Longship Project: This ambitious project involves capturing CO₂ from industrial sources in Norway and storing it under the North Sea. It aims to create a full-scale CCS value chain and serve as a model for future projects.
Challenges to CCS Deployment
Despite its potential, CCS faces several challenges that must be addressed to scale up the technology and make it widely available.
- Cost: CCS is an expensive technology, particularly in the capture phase. Capturing CO₂ from power plants and industrial facilities requires significant energy and infrastructure investments. While costs are expected to decrease as the technology matures, financing remains a major hurdle.
- Energy Demand: CCS requires energy to capture, transport, and store CO₂, which reduces the overall efficiency of power plants and industrial processes. This “energy penalty” is one of the key barriers to widespread adoption.

The global transition to a low-carbon economy is both a challenge and an opportunity. Carbon capture and storage (CCS) offers a critical solution to address the challenge of decarbonizing industries that are difficult to transition to renewable energy sources. In addition to reducing emissions from these sectors, CCS can also be a powerful tool in reversing the damage already done by removing carbon dioxide (CO₂) directly from the atmosphere. This solution is becoming increasingly essential as governments and industries seek innovative ways to meet ambitious climate targets and mitigate the effects of global warming.

The Path Forward: Overcoming Barriers and Seizing Opportunities
While carbon capture and storage is widely recognized as a critical component of the global climate solution, scaling it up requires overcoming several key barriers. However, with the right policy support, innovation, and investment, these challenges can be addressed.
1. Reducing Costs Through Innovation and Collaboration
One of the most significant barriers to widespread adoption of CCS is its high cost. However, costs are expected to decline as the technology matures, and economies of scale are achieved. Innovation in carbon capture methods, such as the development of new solvents, membranes, and materials, will play a crucial role in reducing costs. In addition, collaboration between industries, governments, and research institutions can lead to the sharing of knowledge and resources, further driving down costs and accelerating the deployment of CCS projects.
2. Expanding Government Support and Incentives
Government policies and incentives are essential for driving the adoption of CCS. Policymakers must create an enabling environment by establishing clear regulations, carbon pricing mechanisms, and financial incentives for CCS projects. Countries that have already introduced carbon pricing or tax credits for CCS, such as the United States with its 45Q tax credit, have seen an increase in the number of CCS projects being developed.
Governments can also support CCS by investing in infrastructure, such as pipelines for transporting CO₂ to storage sites, and by funding research and development (R&D) efforts. Public-private partnerships can be particularly effective in mobilizing the resources needed to scale up CCS deployment.
3. Public Engagement and Building Trust
Public perception of CCS can be a barrier to project development, particularly when it comes to the storage of CO₂. Concerns about the safety of long-term storage and the potential for CO₂ leaks must be addressed through transparent communication and rigorous safety standards. Building trust with local communities near potential storage sites is essential for the successful deployment of CCS projects. YCCINDIA’s focus on real-time monitoring and safety systems can play a key role in ensuring that storage operations are secure and that any risks are mitigated.
4. Developing the Necessary Infrastructure
Infrastructure development is another critical factor for the successful implementation of CCS. Building pipelines, storage facilities, and transportation networks for CO₂ requires significant investment and planning. In regions where such infrastructure is not yet in place, governments and industries must work together to create the necessary framework. YCCINDIA’s digital solutions can help optimize the planning and management of these infrastructure projects, ensuring that they are efficient, cost-effective, and environmentally sustainable.
The Potential of Carbon Capture Utilization and Storage (CCUS)
One of the most exciting opportunities in the CCS field is the potential for Carbon Capture Utilization and Storage (CCUS). Instead of simply storing captured CO₂, CCUS aims to find productive uses for it, transforming it into a valuable resource. This not only reduces the need for storage but also creates new economic opportunities for industries that capture carbon.
For example, captured CO₂ can be used to produce synthetic fuels, chemicals, and building materials. Some companies are already using CO₂ to create carbon-neutral fuels that can be used in transportation and industry, helping to reduce reliance on fossil fuels. The development of these markets for captured CO₂ will provide industries with a financial incentive to invest in carbon capture technologies, further driving the adoption of CCS.
