As greenhouse gas emissions continue to rise, climate change is becoming an even more pressing global issue. By the end of this century, carbon dioxide (CO .) had become2) concentration is expected to double. Carbon capture and storage (CCS) technology is widely accepted as an effective way to reduce carbon emissions and keep global temperatures from rising by more than 1.5 to 2°C by 2050.

What is carbon capture and storage?
Carbon capture and storage is designed to prevent carbon dioxide2 From its release into the atmosphere from conventional power plants and industrial activities.
CCS sequesters CO2 Emissions from the manufacturing process, then transportation and injection of compressed carbon dioxide2 In a suitable geological storage place.
Advantages of Carbon Capture Technology
Among the many advantages of carbon dioxide capture and storage is the ability to permanently store carbon dioxide2 that are captured during energy production in underground sediments.
The International Energy Agency believes that CCS can remove up to 20% of carbon dioxide emissions from energy production and industrial facilities.

The social cost of carbon is an estimate of how much climate change will affect the production of one metric ton of carbon dioxide2 Released into the atmosphere every year. By eliminating carbon dioxide2 Right from its source, the social cost of carbon and the net social damage can be lowered.
The captured carbon dioxide can be used to produce plastics and chemicals such as polyurethane on a commercial scale.
Disadvantages of carbon capture technology
Pickups are expensive due to the need for additional power. When this technology is implemented in an industry, the cost of the product will increase if no support is given by the regulatory authorities.
There is no strong evidence that underground CO2 storage is completely safe. Many scientists recommend constantly monitoring storage sites until the area is completely cleared. Large-scale leaks at these sites would render the air unfit for human consumption due to the gas’s extreme toxicity.
How can carbon sequestration help achieve net zero?
CCS can help achieve cost-effective net zero emissions in the following ways:
The use of carbon dioxide capture and storage in industrial sectors that are difficult to decarbonize
It is difficult to decarbonize industrial sectors such as iron, cement and steel production.
According to the Energy Transition and IEC Agency, net zero emissions in these industries may be unattainable due to the high costs of green technology.
Carbon capture and storage technologies are a cost effective method that can be easily used to remove carbon from these industries by storing carbon dioxide2 It was launched during the production of iron and steel.
The captured carbon dioxide can then be used to produce methanol on a commercial scale for use as a fuel.
Mass production of low carbon hydrogen (green fuel)
Carbon capture and storage technologies can be used with coal gasification to cost-effectively produce low-carbon hydrogen. It would be the most cost-effective method in locations where renewable energy is scarce and fossil fuels are inexpensive.
Hydrogen production must expand significantly for net zero emissions, from 70 million tons per year (Mtpa) to 650 tons per year by mid-century.
Hard-to-reach sectors are expected to benefit from hydrogen’s participation in decarbonization. Flexible power generation and residential heating can also benefit from this type of energy.
Demountable low carbon electricity production
Electricity generation must be decarbonized to achieve net zero emissions. CCS-equipped power plants provide grid stability services such as frequency management, standby power, voltage control, and deployable and low-carbon electricity.
The low-carbon grid of the future will be more reliable and sustainable if carbon dioxide capture and storage is used in conjunction with renewable energy.
Recent Developments in Carbon Sequestration
Bioenergy with carbon capture and storage in the UK
The UK government is relying on carbon capture and storage technologies used by bioenergy plants to achieve its climate change goals. The current Drax power plant has already undergone a conversion process from coal to biomass.
CCS will significantly reduce the company’s carbon dioxide2 Effects. Drax hopes to capture 4 million tons of CO22 annually from power plants.
Steam Methane Reformer for Air Products
The steam methane reformer of Air Products, an American company, is used to capture carbon dioxide2 From the Port Arthur oil refinery in Texas. It is capable of producing 500 tons of pure hydrogen every day. According to the US Department of Energy, approximately six megatonnes of carbon dioxide were captured and stored by the facility in April 2020.
CCS Quest Unit
The Scotford Upgrader plant in Alberta, Canada, uses three methane steam reformers to absorb carbon dioxide.2 emissions. In July 2020, the facility deposited five megatons of CO2 safely and permanently2 in a geological repository.
Moomba CCS Project
Santos and Beach Energy, two Australian energy production and exploration companies, have achieved a final investment decision (FID) on the $165 million CCS project at the Momba gas facility. The project will sequester and store 1.7 million tons of carbon dioxide annually in an adjacent reservoir.
Future outlook for carbon capture and storage
Despite the fact that carbon capture and storage technology has been available for a long time, it is struggling to become widespread.
One of the most common reasons against implementing CCS is that it could increase the use of fossil fuels rather than spur investment in renewable and low-carbon energy sources.
However, the Intergovernmental Panel on Climate Change (IPCC) claims that carbon dioxide capture and storage will be required to keep global warming below 1.5 aA, this goal cannot be achieved without the use of these techniques.
