Definition

Carbon capture and storage (CCS) is a technology designed to reduce carbon dioxide emissions from sources like power plants and industrial processes. It involves capturing CO2 before it enters the atmosphere, transporting it, and then storing it underground in geological formations to prevent its release into the environment. This process is crucial for mitigating climate change and achieving emission reduction targets.

5 Must Know Facts For Your Next Test

1. CCS technology can capture up to 90% of the CO2 emissions produced from industrial processes and power generation.
2. The captured CO2 can be transported via pipelines or ships to suitable storage sites, often located deep underground in depleted oil or gas fields or saline aquifers.
3. CCS is seen as a necessary component for achieving net-zero emissions targets in many countries and industries, especially those reliant on fossil fuels.
4. Investment in CCS technology has been increasing, with several large-scale projects already operational, demonstrating its potential to significantly reduce greenhouse gas emissions.
5. Public perception and regulatory frameworks surrounding CCS can impact its deployment; acceptance often hinges on concerns about safety, environmental impact, and economic viability.

Review Questions

• How does carbon capture and storage (CCS) contribute to reducing carbon emissions in industrial processes?
  • CCS plays a vital role in minimizing carbon emissions by capturing CO2 produced during industrial processes before it can escape into the atmosphere. The technology is particularly effective in sectors like cement production and energy generation, where substantial CO2 is emitted. By trapping this gas and securely storing it underground, CCS helps to lower overall greenhouse gas levels and aligns with global efforts to combat climate change.
• Discuss the challenges associated with implementing carbon capture and storage technologies on a large scale.
  • Implementing CCS on a large scale faces several challenges, including high costs of capturing, transporting, and storing CO2. Additionally, suitable geological formations for secure storage are not universally available, which limits site selection. There are also concerns regarding the long-term safety of CO2 storage, public acceptance, and the need for regulatory frameworks that ensure proper monitoring and management of stored CO2 to prevent leaks.
• Evaluate the role of CCS in achieving global climate goals and its potential impact on future energy systems.
  • CCS is essential for meeting global climate goals as it allows for continued use of fossil fuels while significantly reducing associated emissions. Its ability to capture large amounts of CO2 means it can help bridge the gap between current energy demands and sustainable practices. Looking ahead, CCS could enable a transition toward a low-carbon energy system by integrating with renewable energy sources, supporting a cleaner energy mix while maintaining energy security during the transition period.
