The future of carbon capture and storage looks bright. 

Its ability to eliminate the use of fossil fuels has the potential to dramatically reduce global warming. But what are the key elements that will drive this technology forward?

Pre-Combustion Capture

Pre-combustion capture and storage, also known as CCUS, is a promising new technology for reducing carbon emissions in the power industry. 

This technology is used to sequester carbon dioxide in fossil fuels before they are burned. In the process, the fuel is split into hydrogen and CO2, which is then removed for storage or re-use. 


The most common application of CCUS is in the power generation industry. However, a number of industrial processes are also possible with this technology.

Compared to post-combustion capture, pre-combustion capture offers a higher efficiency and lower energy requirements. It is especially useful for the latest generation of coal plants. Although this technology requires some additional capital investment, it is a cost-effective option for large, stationary sources of emission.

Pre-combustion capture can be implemented in new build power plants or retrofitted to existing plants. Using this technology, CO2 is separated from the flue gas using a chemical solvent. 

Once the solvent has been regenerated, the mixture is run through a stripper to remove the CO2 from the gas. After the exhaust is separated, it can be transported by pipeline or ship to storage sites.

Another advantage of utilizing a pre-combustion capture system is the ability to transport the captured CO2 to storage locations deep underground. 

This method can be utilized in depleted coal beds or oil fields. These geological storage sites have the advantage of being porous, which makes them a viable option for the permanent storage of CO2.

Storage Options and Technologies

There are a number of technologies to choose from when deciding on the best CO2 storage method for a particular facility. Some of these include liquid storage, geological storage, and solid storage. All of these options can be deployed to help reduce global warming. For the latter, saline formations and petroleum fields are well-suited for storage.

Several other potential storage options include using the geological storage of CO2 in a reservoir or aquifer. The main disadvantage of storing CO2 in these locations is the cost of transporting the captured gas to the location. 

The most developed CO2 capture and storage technologies are being tested in small scales, but there is still a lot of work to be done in order to fully demonstrate their effectiveness. 

The Transportation

Since CO2 can be stored in liquid, gas, and a solid form, it can be transported by pipeline or by ship. A number of technologies are currently under development, including membranes and solid sorbents.

Carbon dioxide can be transported by ship, pipeline, or land. It can also be stored in deep saline aquifers or in depleted coalbeds. Depending on the storage location, CO2 can be permanently stored or re-used for enhanced oil recovery.

Geological Formations

The storage of CO2 in deep geological formations is an important topic in the debate on carbon capture and storage. Geological formations have been used to store oil and gas for millions of years, and they have the potential to store CO2 as well.

Several potential storage locations include: mineral carbonation, deep saline aquifers, shale basins, and gas fields. In addition, there are several pilot-scale projects that have been conducted around the world.

Deep Saline Aquifers

Deep saline aquifers have the largest capacity for CO2 storage. They are porous rock formations infused with brine and can span huge volumes underground. They are not ideal for industrial purposes. 

Saline aquifers offer a more direct way to store CO2 than other geologic sequestration methods. However, they have been less studied than other potential storage sites. Therefore, an effective storage system must be based on a combination of physical and geochemical trapping mechanisms.

Sealing Mechanism

There are four main mechanisms that prevent CO2 from escaping the storage site. These include structural, physical, geochemical, and residual trapping. 

All four of these mechanisms must be present in order to prevent the migration of CO2. As a result, the effectiveness of a geologic sequestration process depends on the combined effect of all of these mechanisms.

Capacity and Integrity

Some of the most important characteristics of a storage site are the capacity and the integrity of the storage resource. An adequate capacity ensures that the site has the pore volume needed for safe storage. It also allows for the proper injection rates to be maintained. Likewise, the presence of sufficient containment and permeability are vital.

Pilot-scale projects are generally designed to test the feasibility of a particular method of capturing and storing CO2. Such efforts provide a wealth of information about the processes involved in geologic storage. Moreover, they can answer questions that are of interest to prospective users of such technology.

While the cost of capturing CO2 is prohibitive, the revenue from producing oil can offset the costs of storing it. Additionally, if the storage site is a geologic one, it is regulated by national laws, and the risks to humans and the environment are minimized through appropriate measurement systems. 

Direct Air Capture

Direct Air Capture (DAC) is an emerging technology for removing CO2 from the atmosphere. In this method, CO2 molecules are trapped by a non-toxic potassium hydroxide solution which flows over thin plastic surfaces. 

This process sequesters the CO2 from the air, resulting in the capture of hundreds of tons of CO2 per year. The captured carbon is then recycled for reuse in the original capture solution.

Currently, direct air capture is being deployed in small-scale plants in Canada and the United States. The first large-scale DAC plant will be operational in the Permian Basin in southwest USA by the mid-2020s. These facilities have a capture capacity of up to one million tonnes of CO2 per year.

Large-scale deployment of DAC is possible in areas where the energy supply is abundant and cheap. For example, in the United States, a natural gas processing facility has begun supplying carbon dioxide to oil fields through the first large-scale pipeline in West Texas.

A number of companies are exploring a variety of DAC technologies. One company, Carbon Engineering, is building a direct air capture facility in Squamish, Canada, with plans to be operational in 2024. 

Another, 1PointFive, is developing megaton-scale facilities in the U.S., with a goal of capturing 70 large-scale DAC facilities by 2035.

Among other companies, the Norsk e-Fuels consortium is developing a facility to produce synthetic fuels from carbon captured from the atmosphere. It is targeting the production of up to three million liters of synthetic fuels by 2024. Other projects include the HIF Haru Oni eFuels Pilot Plant, which aims to produce synthetic fuels from electrolysis-based hydrogen.

Another DAC approach is based on sorbents and amine materials. They use porous solid supports, which bind to the CO2 molecules in the air. These sorbents operate at medium or low pressure.

While DAC is still in its early stages, it has received significant support from the European Commission. Several research and innovation programmes are aimed at supporting this technology.

However, the future of DAC will depend on the technology’s development and technological performance. More research is needed to ensure safe, efficient, and reliable storage of captured carbon. 

Also, there are concerns about the impact of pipelines, water pollution, and seismic activity. Nevertheless, direct air capture remains an important step in the fight against climate change.


The future of carbon capture technologies is full of promise and potential. As the world continues to struggle with the effects of climate change, these technologies have the ability to play a major role in reducing global emissions. 

With increased investment and development, we can move closer towards a cleaner, healthier planet for all. Carbon capture technology has the potential to change the way we look at energy production and to reduce our reliance on fossil fuels.
