Carbon Capture Technology



Climate change is currently a major concern on the global ladder. Extreme weather, rising sea levels, and species extinction are all results of an unprecedently fast rate of global warming. Greenhouse gas emissions, particularly CO2, cause climate change.

Reduced greenhouse gas emissions are necessary if climate change’s effects are to be lessened. Carbon capture technology (CCT) is a promising technology that can assist in achieving this objective.

Like with every technology, it has both advantages and disadvantages. In this article, we are going to learn about carbon capture technology. Also, in this article, let us know what are its advantages and disadvantages.


What is the meaning of carbon capture technology?

Carbon capture technology, often referred to as carbon capture and storage (CCS), is a mechanism for carbon dioxide from industrial operations and its storage or recycling.  Carbon capture technology’s objective is to release and prevent the discharge of carbon dioxide into the atmosphere. It seeks to reduce greenhouse gas emissions as well.  


Significance of Carbon Capture Technology

Increasing greenhouse gas emissions from numerous businesses have caused substantial environmental harm, including global warming, sea level rise, and harsh weather events. Carbon capture technology is essential for mitigating these negative consequences and achieving a more sustainable future. Listed below are some of the greatest benefits of carbon capture technology:

  • Reducing Emissions of Greenhouse Gases: Carbon capture technology can contribute to a 90% reduction in greenhouse gas emissions from industrial operations and electricity production. This decrease can potentially attenuate the negative consequences of climate change and limit global warming.
  • Enhancing Air Quality: In addition to CO2, carbon capture technology may minimise air pollution by absorbing additional pollutants. This may result in improved air quality and public health.
  • Creating Fresh Employment: The creation and implementation of carbon capture technologies can generate new employment possibilities in various sectors. This can help economic growth and sustainable development.


Carbon Capture Technology Types

The three principal forms of carbon capture technologies are post-combustion and oxyfuel combustion.

  • After Combustion: The most prevalent form of carbon capture technology is post-combustion carbon capture. It absorbs carbon dioxide following the combustion of fuel. This device captures carbon dioxide from flue gas using solvents, which are separated, stored, or recycled.
  • Before Combustion: In pre-combustion carbon capture technology, coal or natural gas is gasified to generate a hydrogen-rich gas. The carbon dioxide is subsequently caught, stored, and recycled.
  • Oxyfuel Combustion: Oxyfuel combustion Carbon capture method requires burning fuel in a pure oxygen environment instead of air. This technique generates a flue gas composed primarily of carbon dioxide, readily caught, stored, and reused.


Carbon Capture Technology Faces the Following Obstacles:

Although carbon capture technology has the potential to mitigate climate change and impact, it faces many obstacles.

  • High expense: The high expense of carbon capture technology is one of the main obstacles. At present, carbon dioxide is more expensive to store than to be released into the environment. Due to the energy needs of the technology and the necessity for infrastructure to transport and store the captured carbon dioxide, the price is quite expensive.
  • Energy Requirements: The energy needs of carbon capture systems are another obstacle. Carbon capture technology necessitates a substantial quantity of energy, which might raise the price of power generation. Yet, there are ongoing efforts to produce more energy-efficient carbon capture systems.
  • Transportation and Storage: Carbon dioxide storage and transportation collected by carbon capture technologies are also significant obstacles. There are issues regarding the safety and stability of underground storage facilities for carbon dioxide. In addition to being difficult, transporting collected carbon dioxide necessitates the creation of new infrastructure.


Existing Power Plants May Be Retrofitted with Carbon Capture Technology If Feasible:

Carbon capture after combustion may be adapted to existing power facilities. This method involves adding carbon dioxide capture equipment to a power plant. On the other hand, pre-combustion carbon capture technology cannot be retrofitted since it requires substantially refurbishing power plants.


Advantages of Carbon Capture Technology Include:

Notwithstanding its obstacles, carbon capture technology offers several advantages. It may minimise greenhouse gas emissions, so lessening climate change’s consequences is one of its primary benefits. In addition to improving air quality, carbon capture technology may reduce the discharge of pollutants from industrial activities.

Furthermore, carbon capture technology can generate new employment prospects. To develop and install carbon capture technologies, engineers, scientists, and other professionals are needed. This can provide employment prospects in the energy industry.


Pros and Cons of Carbon Capture Technology:

Carbon capture technology is a potential technology that can aid in mitigating climate change’s consequences.

Like with every technology, it has both benefits and drawbacks. Here are pros and cons of carbon capture technology.

  • 5) False Feeling of Security: According to some, carbon capture technology might provide a false sense of security, delaying the adoption of renewable energy sources.


Conclusion

By minimizing greenhouse gas emissions, carbon capture technology helps lessen climate change’s consequences. Nevertheless, the technique faces various obstacles, such as high cost, energy needs, storage and transportation, and restricted use. Notwithstanding these obstacles, carbon capture technology is a crucial technology that may supplement renewable energy sources in the battle against climate change.
