Understanding Carbon Capture and Storage (CCS)

Carbon Capture and Storage (CCS) refers to a set of technologies that capture carbon dioxide (CO2) emissions produced from the use of fossil fuels in electricity generation and industrial processes, preventing the CO2 from entering the atmosphere. The captured CO2 is then transported and stored underground in geological formations. This technology is critical for New Zealand as it seeks to reduce its greenhouse gas emissions and work towards its goal of achieving carbon neutrality by 2050. As New Zealand continues to rely heavily on agriculture and fossil fuels, CCS presents a viable solution to mitigate emissions while maintaining economic stability.

In New Zealand, emissions from the agriculture sector are significant, and CCS technologies could play a crucial role in capturing emissions from industrial processes. For example, the cement industry is one of the largest industrial sources of CO2 emissions. Implementing CCS in this sector could significantly contribute to the country’s overall emission reduction goals. The New Zealand government has recognized the importance of CCS and included it in discussions around zero carbon innovation. By investing in CCS technologies, New Zealand can lead the way in developing sustainable practices that could be beneficial for other nations as well.

Current CCS Technologies and Their Applications

Several CCS technologies are currently available, varying in sophistication and applicability. The most common methods include post-combustion capture, pre-combustion capture, and oxy-fuel combustion. Post-combustion capture is particularly relevant for existing power plants in New Zealand, where CO2 is removed from flue gases after combustion. This method is relatively flexible and can be retrofitted to existing facilities, making it a practical option for New Zealand’s energy sector.

Pre-combustion capture, on the other hand, involves removing CO2 before combustion occurs, typically applied in gasification processes. Oxy-fuel combustion uses pure oxygen instead of air, resulting in a flue gas that is primarily CO2 and water vapor, making it easier to capture. Developing pilot projects that utilize these technologies would be beneficial for New Zealand. For instance, collaborations between universities and industries could lead to innovative solutions tailored to local conditions. The potential for CCS technologies to reduce emissions in line with the Zero Carbon Act is an encouraging prospect for New Zealand’s decarbonization efforts.
