CO2tallennus

CO2tallennus, also known as carbon capture and storage (CCS), is a technology aimed at mitigating climate change by capturing carbon dioxide emissions from large industrial sources, such as power plants and manufacturing facilities, and preventing them from entering the atmosphere. The captured CO2 is then transported, typically via pipelines, to a suitable geological site for permanent storage deep underground.

The process of CO2tallennus involves several key stages. First, capture technologies are employed to separate CO2 from other gases produced during industrial processes. This can be done using methods like post-combustion capture, pre-combustion capture, or oxy-fuel combustion. Once captured, the CO2 is compressed into a liquid or supercritical fluid state for efficient transportation. Finally, the CO2 is injected into deep geological formations, such as depleted oil and gas reservoirs, saline aquifers, or unmineable coal seams, where it is expected to remain trapped for millennia.

The effectiveness and long-term safety of CO2tallennus depend on rigorous site selection, monitoring, and verification protocols. Potential risks include leakage of stored CO2, which could impact local ecosystems or groundwater. However, proponents argue that with proper management and geological assessment, CO2tallennus can be a vital tool in reducing greenhouse gas concentrations and achieving climate targets, alongside other decarbonization strategies. Research and development continue to improve the efficiency and cost-effectiveness of these technologies.
