CCS is the name given to technologies that capture and store carbon dioxide

Carbon capture and storage, or CCS, is a combination of technologies that capture and store carbon dioxide deep underground, preventing its release into the atmosphere.

At Shell, we believe that CCS will be essential for helping society to achieve net-zero emissions. Our ambition is to work with governments, customers, and partners to unlock the potential for CCS around the world.

Shell’s target is to become a net-zero emissions energy business by 2050, and we know that our business plans need to change to make this happen. Our priority is to avoid emissions, for example by adopting solutions that are emissions-free when used. When this isn’t possible, we work to reduce emissions, for example by making use of lower-carbon fuels and technologies like CCS. If it is not possible to either avoid or reduce emissions, we will turn to the compensation of emissions, such as using carbon credits.

Capturing and safely storing carbon is an option that’s available now. It can help us reduce the amount of carbon entering the atmosphere and even be used to remove existing carbon, something that is critical for the long-term health of our planet.

How does CCS work?

CCS prevents the release of CO2 into the atmosphere. It is generally used to help decarbonise industrial processes, such as the production of steel, cement, or chemicals, or to help decarbonise power stations that use hydrocarbons to generate electricity. These are all areas where there are not currently scalable low-carbon alternatives to the oil and gas they use.

In CCS facilities, CO2 is first separated from any other gases produced. It is then compressed and transported via pipe or ship to locations where it can be stored. Finally, the CO2 is injected into geological formations deep underground for permanent storage.

Take a look at the process below for more details:

Shell’s CCS projects

From Canada to Norway, from Australia to the Netherlands, Shell is part of developing CCS technology globally.

Developing and deploying Shell CCS technology

Shell is also a leading provider of CO2 capture technologies which we use and license to help our customers reduce their emissions.

Shell’s ADIP-ULTRA solvent technology provides pre-combustion CO2 removal and has been applied to more than 500 units around the world, including the Shell operated Quest project in Canada. On Quest, the ADIP technology is used to capture the CO2 from three hydrogen manufacturing units. The CO2 is then compressed and piped 65 km to three wells which inject the CO2 two kilometers underground. Find out more.

Shell’s Cansolv technology works by capturing CO2 post-combustion. Shell licenses the Cansolv technology across multiple industries including power, steel, cement and refining. At the start of 2022, it was announced that Shell’s Cansolv technology would be fitted to the gas emitting stacks of the VPI Immingham power station in the UK. There, the technology will capture up to 95% of the CO2 in the gas, preventing it from being emitted into the atmosphere and allowing it to be compressed, transported and safely stored.

In Canada, the Shell Cansolv system has been installed on one unit of the Boundary Dam power station where it captures around 1 million tonnes of CO2 a year. Boundary Dam is SaskPower’s largest coal-fired power station and a significant source of power for the region.

In Norway, the Technology Centre Mongstad, or TCM, is the world’s largest test centre for developing CO2 capture technologies. Able to simulate real-world conditions to test mature and emerging CCS technologies, the work done at TCM helps to reduce the costs and risks associated with carbon capture technology deployment. TCM is owned by the Norwegian State through Gassnova together with Shell, Equinor and TotalEnergies.

One of the biggest challenges associated with CCS is the transportation of captured CO2 between capture sites and storage locations. For the most part, CCS is transported by pipeline. However, where a pipeline is not feasible, shipping can provide an effective and efficient method of transporting CO2 in bulk. Shell Shipping and Maritime has played an active role in the development and procurement of the world’s first vessels specifically designed to carry liquid CO2 derived from CCS.

The future of CCS

Most climate scientists are clear that the world needs CCS technology if society is to achieve net zero emissions. Shell is currently investigating more CCS opportunities in the North Sea, Americas and Asia and we seek to have access to 25 million tonnes of CO2 per annum of CCS capacity by 2035.

In many countries there isn’t currently sufficient regulatory support or a clear business model for. To address these challenges, Shell is advocating for policy mechanisms that drive deployment of CCS at scale, and industry partnerships to decarbonise hard-to-abate sectors.
