Kaasuvoimansiirto, also known as carbon capture and storage (CCS), is a technology aimed at reducing carbon dioxide (CO2) emissions from power plants and industrial processes. The process involves three main stages: capture, transport, and storage.

In the capture stage, CO2 is separated from other gases produced during the combustion of fossil fuels. This can be achieved through various methods, such as post-combustion capture, pre-combustion capture, or oxy-fuel combustion. Post-combustion capture is the most common method, where CO2 is captured from the flue gas after the fuel has been burned.

Once captured, the CO2 is compressed and transported to a storage site. This can be done via pipelines or ships, depending on the distance and location of the storage site. The transport stage requires significant energy and infrastructure, making it a critical component of the overall CCS process.

The final stage is storage, where the CO2 is injected into underground geological formations, such as depleted oil and gas reservoirs, unmineable coal seams, or deep saline formations. These formations have the capacity to store large volumes of CO2 and are considered safe and secure for long-term storage.

CCS technology has the potential to significantly reduce CO2 emissions from power generation and industrial processes. However, it is important to note that CCS is not a standalone solution to climate change. It should be part of a broader strategy that includes renewable energy sources, energy efficiency, and other mitigation measures. Additionally, the economic and environmental impacts of CCS should be carefully considered and managed.
