Daniel Roberts Newcastle Carbon Capture

8 mins read

Carbon capture, utilization, storage, or simply CCUS is a technique that absorbs carbon dioxide emissions from sources such as coal-fired power stations and reuses or stores them not to enter the environment. Oil and gas reservoirs, unmineable coal seams, and deep saline reservoirs are examples of geologic formations accumulating crude oil, natural gas, brine, and carbon dioxide for millions of years.

The Energy Department sponsors research and development of tools for evaluating the environmental fitness and safety of potential geologic storage sites and the prediction of future capacity within them. We are also creating models to mimic the flow of stored carbon dioxide to understand better and forecast chemical changes and the implications of increased pressure.

What is Carbon Capture and Storage?

It is a method of lowering carbon emissions that might be critical in combating global warming. It is a three-step process that involves absorbing carbon dioxide produced by electricity generation or industrial activity such as steel or cement production, transporting it, and storing it deep below. In this section, we will look at the possible benefits of CCS and how it works.

What is CCS?

CCS entails capturing carbon dioxide (CO2) emissions from industrial operations such as steel and cement manufacture and the combustion of fossil fuels in power generation. This carbon is then transferred by ship or pipeline from where it was created and buried deep down in geological formations.

How can CCS help prevent global warming?

On the report of the Intergovernmental Panel on Climate Change, if we are to fulfill the Paris Agreement’s goal of limiting future temperature increases to 1.5 degrees Celsius, we must do more than enhance our efforts to reduce emissions. We also need to deploy systems that remove carbon from the atmosphere; CCS is one of these technologies, and it may play an essential role in addressing global warming.

How does CCS work?

The three steps to the CCS process:

  1. Capture: CO2 is isolated from other gases generated in industrial operations, such as those at coal and natural-gas-fired power plants, steel mills, and cement plants.
  2. Transport: The CO2 is subsequently compressed and transferred to a storage location through pipelines, road transport, or ships. 
  3. Storage: Finally, the CO2 is pumped far below into rock formations for long-term storage.

Where are carbon emissions stored in CCS?

You might store carbon emissions in saline aquifers or depleted oil and gas reserves.

These are typically required to be 1km or further underground. For example, a storage location for the planned Zero Carbon Humber project in the United Kingdom is a saline aquifer termed ‘Endurance,’ which is located in the southern North Sea, approximately 90 kilometers offshore. Endurance is located roughly 1.6km underneath the seafloor and can store massive volumes of CO2.

So what’s the distinction between CCUS and CCS?

Along with CCS, a similar idea is CCUS, which stands for Carbon Capture, Utilization, and Storage. Instead of storing carbon, the notion is that you may reuse it in industrial processes by being converted into concrete, biofuel, or plastics.

Is carbon storage as part of CCS safe?

According to the Global CCS Institute, CCS is a proven technology that has been in safe operation for over 45 years. Furthermore, all of the components of CCS are tried-and-true technologies that have been employed on a commercial basis for decades.

Where is CCS being used already?

According to the Global CCS Institute’s 2019 report, there were 51 large-scale CCS facilities across the world at the time. Nineteen of them were operational, four were under construction, and the rest were in different phases of development.

Twenty-four of them were in the Americas, twelve in Europe, twelve in Asia-Pacific, and two in the Middle East.

Where was the first CCS facility?

CCS has been in use in the United States since 1972, with multiple natural gas facilities in Texas capturing and storing more than 200 million tons of CO2 underground.

  • Carbon capture, utilization, and storage technology can collect more than 90% of CO2 emissions from power plants and industrial enterprises. 
  • Carbon dioxide collected can be used productively in increased oil recovery and the production of fuels, construction materials, and other products, or they can store it in underground geologic formations. 
  • Twenty-six commercial-scale carbon capture projects are running globally, with another 21 in early development and 13 in advanced development nearing front-end engineering design (FEED). 
  • Carbon capture can reduce 14 percent of global greenhouse gas emissions by 2050 and is regarded as the only viable approach to accomplish substantial decarbonization in the industrial sector.


Even as countries diversify their energy portfolios, fossil fuels are anticipated to provide the vast majority of the world’s energy needs for the foreseeable future. Therefore, accelerating the implementation of carbon capture technology is critical to reducing emissions from these power facilities and industrial operations such as cement and steel production.

More than half of the models included in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change need carbon capture to remain under 2 degrees Celsius of pre-industrial warming. The expenses of reducing emissions increased by 138 percent for models that did not include carbon capture.

Carbon dioxide has been used to extract more oil from existing oil fields in the United States for about a half-century in a method known as enhanced oil recovery (EOR). Companies in the United States are also investing in new technology to reuse captured carbon emissions in novel ways, such as jet fuel and automotive seats. In addition, researchers are investigating new applications, such as converting carbon emissions into algal biofuels and construction materials, resulting from the NRG COSIA Carbon XPRIZE.

As many experts consider hydrogen a clean fuel of the future, many anticipate it to decarbonize the industrial sector significantly. A method like natural gas reforming with carbon capture technology appears to be the most cost-effective alternative for creating clean hydrogen. This process creates “blue hydrogen” by reforming natural gas into hydrogen and carbon dioxide; the carbon dioxide byproduct will be collected, delivered, and stashed in deep geologic formations. In addition, when renewable electricity is utilized to power the carbon capture plant, the inclusion of carbon capture practically eliminates emissions from the hydrogen generation process.
