Basics of Carbon Capture and Storage

CCS Basics


As the world continues to look for ways to reduce its reliance on fossil fuels, several different technologies are being developed to capture carbon dioxide (CO2) from industrial sources and store it deep underground. Carbon capture and storage (CCS) is seen as a key part of the fight against climate change, and there have been some significant developments in technology in recent years.

In this blog post, we’ll take a look at some of the basics of carbon capture technology and what they could mean for the future of the CCS industry.

What is carbon capture?

Carbon capture and storage (CCS) is a set of technologies that capture carbon dioxide from industrial sources and store it deep underground. The captured CO2 can be pumped into depleted oil and gas wells, deep saline aquifers, or other geological formations. This process prevents the emitted carbon dioxide from entering the atmosphere, helping to reduce global emissions. In recent years, several CCS projects have been implemented around the world, including the world’s first CCS project in the North Sea and a plant in Canada that captures 1 million tonnes of CO2 annually. These projects demonstrate the potential of CCS technology to reduce emissions while enabling the continued use of fossil fuels.

What are the benefits of carbon capture technology?

The benefits of CCS technology are numerous. First and foremost, it allows carbon dioxide to be captured and stored underground, helping to reduce global emissions. By capturing and storing carbon dioxide, CCS helps to reduce the amount of CO2 in the atmosphere, thus reducing the adverse effects of climate change. Additionally, CCS technology can be used to develop new revenue streams for industry, as carbon dioxide can be stored and sold for use in enhanced oil recovery (EOR) operations, or for use in other industries such as the beverage industry. Furthermore, CCS could also be used to create carbon credits, which could be traded for revenue to offset costs associated with emissions reduction efforts.

How does carbon capture technology work?

There are two main types of CCS technology, post-combustion and pre-combustion. Post-combustion CCS involves capturing and storing carbon dioxide from the exhaust of power plants or other industrial sources. During post-combustion, the exhaust gases pass through an absorber or adsorber, which binds the CO2 molecules and separates them from the other exhaust gases. The extracted CO2 is then compressed and stored deep underground. Pre-combustion CCS involves capturing the carbon dioxide before it is emitted into the atmosphere. During pre-combustion, the fossil fuel containing CO2 is scrubbed and CO2 is extracted from the mixture and stored underground.

What are the challenges of carbon capture technology?

Despite its potential benefits, CCS technology faces several challenges. The cost of implementing CCS technology is a major obstacle, as it is expensive to build and operate a CCS facility. Furthermore, there is limited knowledge regarding the long-term safety and effectiveness of carbon storage, particularly when it comes to leakage and the potential impacts on the environment. Another challenge is the lack of infrastructure to support the transportation and storage of captured carbon dioxide. In addition, CCS operations are limited by existing legal and regulatory frameworks, which can create additional red tape and stifle innovation.

What are the future plans for carbon capture technology?

In the coming years, there is a lot of potential for CCS technology to be further developed and deployed around the world. Several countries have already announced plans to invest in CCS, including the UK, which has committed more than £1 billion to develop the technology. In addition, research and development (R&D) into new CCS technologies is ongoing. In the US, for example, the US Department of Energy’s National Renewable Energy Laboratory (NREL) is working to develop a cost-effective CCS solution for power plants and other industrial sources.


Carbon capture and storage technology have the potential to be a major player in the fight against climate change. Recent developments in the technology have saved potentially millions of tonnes of carbon dioxide from entering the atmosphere while creating new revenue streams for the industry. However, there are still a number of challenges that need to be addressed in order to make the technology more cost-effective and reliable. With increasing investment in R&D and the commitment of governments around the world to reduce emissions, it is likely that CCS technology will become even more important in the future.
