What is CCS and How Does it Work?
Carbon capture and storage (CCS) technology plays a vital role in reducing emissions and combating climate change. But what exactly is CCS and how does it work?
CCS is a process that aims to capture carbon dioxide (CO2) emissions before they are released into the atmosphere. It involves capturing CO2 from industrial processes and storing it deep underground, preventing it from contributing to the greenhouse effect.
Unlike carbon dioxide removal (CDR) technologies that focus on withdrawing CO2 already present in the atmosphere, CCS focuses on capturing emissions at the source. It can capture emissions from various sectors, including fossil fuel production, industrial manufacturing, and power generation.
However, it is essential to note that while CCS can capture emissions from fossil fuel production, it does not address downstream emissions when the fuel is burned. Moreover, implementing CCS requires significant amounts of energy, which can lead to additional emissions if that energy comes from fossil fuels.
In some cases, CCS technology can even produce more emissions than it sequesters. Therefore, it is crucial to critically analyze the feasibility of CCS and explore alternative energy sources that can outcompete fossil fuels in reducing emissions in the long run.
Despite these challenges, CCS is currently considered one of the primary means to address emissions in hard-to-abate sectors like cement production. It enables the capture of CO2 from industrial processes that would otherwise be released into the atmosphere.
In conclusion, while CCS technology offers the potential to reduce emissions, it must be implemented alongside renewable energy solutions to achieve significant and sustainable emissions reduction in the fossil fuel sector.
Is CCS Technologically Feasible at Scale?
Carbon capture and storage (CCS) technology has made gradual progress over the years, but its large-scale deployment still faces significant challenges and feasibility concerns. Currently, there are only 30 commercial CCS projects globally, which falls short of previous projections by the International Energy Agency.
Scaling up CCS in the fossil fuel sector would require substantial investment and construction of carbon capture facilities. While many emissions reduction models consider fossil fuel CCS as a vital component, achieving the necessary levels of carbon storage remains a major hurdle.
Moreover, there are geological limitations when it comes to safe underground storage, and the long distances between emitting facilities and suitable repositories create implementation barriers.
Despite these challenges, CCS technology continues to be explored and refined, as it offers a potential solution for reducing emissions in hard-to-abate sectors. With further advancements, research, and investment, CCS may become more feasible at a larger scale, contributing to global efforts in emissions reduction.
Is CCS Cost Competitive?
The costs of implementing carbon capture and storage (CCS) technology can vary depending on several factors. These factors include the industrial process, the concentration of CO2 being captured, the distance of transportation, and the location of storage. Capture costs typically range from CAD 27–48/tCO2 to CAD 50–150/tCO2, but long-term cost data is still limited.
However, when it comes to cost competitiveness in the fossil fuel sector, CCS has been slow to fall in cost due to its complexity and the need for customization in various applications. Moreover, the implementation of CCS still heavily relies on government subsidies to make it economically viable.
While CCS is an important technology for reducing emissions, it is among the most expensive and least effective options for mitigation in the near term, especially when compared to alternative energies. Renewable energy sources such as solar and wind power are becoming increasingly cost competitive and have the advantage of being able to provide clean energy without the need for CCS.
Closer Look: CCS in Coal-Fired Power Generation
Carbon capture and storage (CCS) technology has made slow progress in the coal power sector, with only a limited number of operational facilities worldwide. However, a few countries such as China, the United States, and Canada have managed to establish CCS facilities at coal-fired power plants, capturing a small portion of CO2 emissions.
These operational CCS facilities have faced challenges in achieving their intended levels of captured emissions. Despite these obstacles, they represent an important step towards reducing the environmental impact of coal-fired power generation.
India, on the other hand, has not announced significant policy support for CCS in coal-fired power generation, although there seems to be emerging interest in the technology. Continued exploration and implementation of CCS in the coal power sector will be crucial for achieving significant emissions reductions and transitioning to a greener energy future.
Closer Look: CCS in Canada’s Oil and Gas Sector
Canada is actively engaged in the adoption of carbon capture and storage (CCS) technology, particularly in its oil and gas sector. The country boasts several operational CCS projects that contribute to the reduction of emissions in this industry. These projects have the primary objective of enabling further extraction through enhanced oil recovery (EOR). However, it is important to note that while CCS in the oil and gas sector captures a portion of Canada’s total emissions, it does not address the majority of downstream emissions resulting from burning fossil fuels.
Despite this limitation, CCS projects in Canada’s oil and gas sector have received extensive financial support from the government. This support demonstrates the commitment to finding solutions that reduce emissions and contribute to a more sustainable future. However, it is crucial to recognize that CCS prolongs the production and reliance on fossil fuels, which may hinder the transition to cleaner energy sources in the long term.
While CCS projects in Canada’s oil and gas sector play a role in reducing emissions, it is essential to explore complementary strategies that address the downstream emissions associated with the burning of these fuels. This may involve a comprehensive approach that combines CCS with the adoption of alternative energy sources and the development of sustainable solutions.
What Role Will Fossil Fuel CCS Play in Limiting Warming to 1.5°C?
In order to limit global warming to 1.5°C, it is crucial to significantly reduce the production of oil and gas by 2050. While fossil fuel CCS technology is not considered a central solution, it can potentially serve as a pathway to allow for the continued expansion of fossil fuel production while mitigating its environmental impact.
Existing reserves of fossil fuels are already sufficient to meet global demand under the 1.5°C pathway, rendering the development of new oil and gas fields unnecessary. Therefore, the focus should be on declining oil and gas production in order to align with the goal of limiting warming.
In addition to oil and gas, coal production also needs to undergo a significant decline to align with the 1.5°C target. This transition away from coal is essential due to its high carbon intensity and negative environmental impact.
By implementing measures to reduce the production of fossil fuels, such as improving energy efficiency and transitioning to renewable energy sources, we can effectively limit warming to 1.5°C and pave the way for a more sustainable and climate-friendly future.
What is CCUS and Its Role in Clean Energy Transitions?
Carbon capture, utilisation, and storage (CCUS) is a crucial technology in the pursuit of clean energy transitions and reducing emissions. CCUS involves capturing CO2 from large emission sources, such as power plants and industrial facilities, and utilizing or storing it to prevent it from entering the atmosphere.
CCUS can be retrofitted to existing power and industrial plants, allowing them to continue operating while reducing their carbon footprint. This is particularly beneficial in hard-to-abate sectors such as cement, steel, and chemicals, where alternative decarbonization options may be limited.
One of the key advantages of CCUS is its role in enabling the production of low-carbon hydrogen. By capturing CO2 from large emission sources, CCUS can provide a source of CO2 for hydrogen production, supporting the decarbonization efforts in other parts of the energy system.
Additionally, CCUS plays a critical role in emissions reduction by removing CO2 from the atmosphere to balance unavoidable emissions. This helps in achieving net-zero emissions and mitigating the impact of climate change.
“CCUS is a game-changer in the transition to a cleaner and more sustainable energy future. By capturing and reusing or storing CO2, we can significantly reduce greenhouse gas emissions and accelerate the shift towards a low-carbon economy.”
Unlocking the Potential of CCUS

While further advancements and innovations are needed to enhance the efficiency and cost-effectiveness of CCUS, its utilization in clean energy transitions holds significant promise in achieving a sustainable, low-carbon future.
The Process of Carbon Capture and Storage
Carbon capture and storage (CCS) is a vital technology for combating climate change by reducing CO2 emissions. It involves capturing carbon dioxide from large sources such as power plants, industrial facilities, and even the open atmosphere.
There are three main techniques used in CCS:
- Post-combustion: This method captures CO2 after the fossil fuel is burned. It is commonly used in existing power plants and industrial facilities, making it a flexible option for reducing emissions.
- Pre-combustion: With pre-combustion, CO2 is captured before the fossil fuel is burned. This technique is often utilized in integrated gasification combined cycle (IGCC) plants. It offers the advantage of capturing CO2 with high purity, making it suitable for various applications.
- Oxyfuel combustion: Oxyfuel combustion involves burning the fossil fuel in pure oxygen instead of air. This results in a flue gas consisting primarily of CO2 and water vapor, making it easier to capture and separate CO2 for storage.
Once CO2 is captured, it needs to be transported to storage sites. This can be done through pipelines, ships, rail, or trucks, depending on the distance and specific requirements of the project.
When it comes to storage, there are several options available:
- Deep geological formations: This includes storing CO2 in deep underground formations such as oil fields, saline aquifers, or depleted gas reservoirs. These formations provide secure storage options that have been extensively researched and utilized.
- Mineral storage: CO2 can be stored in a solid form by reacting it with certain minerals, such as basalt. This process, known as mineral carbonation, turns CO2 into stable and long-lasting compounds.
- Enhanced oil recovery (EOR): In some cases, CO2 can be used for enhanced oil recovery, where it is injected into oil reservoirs to extract additional oil. This process not only stores CO2 but also increases domestic oil production.
Once CO2 is stored, rigorous monitoring and verification methods are implemented to ensure the proper containment of CO2 and prevent any potential leakage.
Carbon capture and storage technology offers a promising solution for reducing greenhouse gas emissions. By capturing CO2 from large sources and safely storing it underground, CCS plays a crucial role in mitigating climate change and paving the way for a more sustainable future.
The Future of CCS Deployment
The deployment of carbon capture and storage (CCS) technology has gained significant momentum in recent years, with over 500 projects in various stages of development globally. This increased interest and activity in CCS demonstrates the growing recognition of its potential in combating climate change and transitioning to a low-carbon future.
However, despite the progress made, the current level of CCS deployment is still below what is required to achieve the Net Zero Scenario, which aims to limit global warming to 1.5°C. To fully realize the potential of CCS, continued research and development, as well as the establishment of regulatory frameworks, are essential.
Addressing the key challenges of cost competitiveness, scalability, and societal acceptance is crucial for the future deployment of CCS. The cost of CCS projects needs to be further reduced to ensure its economic viability and attractiveness compared to alternative energy sources.
“CCS has the potential to play a significant role in reducing CO2 emissions, but it requires a comprehensive approach that includes technological advancements, supportive policies, and public acceptance.”
– Dr. Emily Carter
Scalability is another important aspect to consider. As the world strives to decarbonize various sectors, including power generation and industrial processes, the scalability of CCS solutions becomes vital to achieve meaningful emissions reductions.
Furthermore, societal acceptance plays a significant role in the successful deployment of CCS. Public understanding and support, along with effective communication about the benefits and safety of CCS, are crucial for its widespread adoption.
By addressing these challenges and continuing to drive innovation and investment in CCS, we can unlock its full potential and accelerate the transition towards a greener, more sustainable future.
