CCS

(General Information)

Carbon Capture and Storage (CCS) is a technology that aims to capture carbon dioxide (CO2) emissions from industrial processes and store them permanently, typically underground, to prevent them from being released into the atmosphere and contributing to climate change. Here are some key points about CCS.

1

Capture:

CCS involves the capture of CO2 emissions from various sources, such as power plants, cement factories, and industrial processes. There are several different capture technologies, including post-combustion capture, pre-combustion capture, and oxy-fuel combustion, which can be used depending on the specific source of emissions.

2

Transport:

Once CO2 is captured, it needs to be transported to a suitable storage site. This is typically done via pipelines, ships, or trucks, depending on the distance and location of the storage site. Transportation of CO2 requires careful planning, monitoring, and safety measures to ensure the secure and efficient movement of the captured CO2.

3

Storage:

CO2 captured from industrial processes is typically stored underground in geological formations, such as depleted oil and gas reservoirs, saline aquifers, or coal seams. The CO2 is injected into these formations and stored permanently, preventing it from entering the atmosphere. Storage sites are carefully selected based on their capacity, safety, and environmental suitability, and are closely monitored to ensure the integrity of the storage and to prevent any potential leaks.

4

Environmental Benefits:

CCS has the potential to significantly reduce greenhouse gas emissions by capturing and storing CO2 from industrial processes that are major sources of emissions. It can help to mitigate climate change by preventing CO2 from entering the atmosphere and contributing to global warming. CCS can also be used in combination with other renewable energy sources, such as biomass, to create a process known as bioenergy with carbon capture and storage (BECCS), which can potentially result in net-negative emissions.

5

Challenges:

While CCS has the potential to be a valuable tool in mitigating climate change, there are also challenges associated with its implementation. These challenges include high costs, technical feasibility, regulatory frameworks, public acceptance, and long-term monitoring and liability issues associated with storing CO2 underground. There are ongoing efforts to address these challenges and develop more cost-effective and sustainable CCS technologies.

6

Global Deployment:

CCS is being deployed in various countries around the world, including Norway, Canada, the United States, Australia, and the United Kingdom, among others. These countries are investing in CCS research, development, and implementation as part of their strategies to reduce greenhouse gas emissions and meet climate change targets.

In summary, CCS is a technology that has the potential to significantly reduce greenhouse gas emissions from industrial processes and contribute to global efforts to mitigate climate change. However, it also faces challenges that need to be addressed for wider deployment and long-term sustainability.
