CO2käitlemise

CO2käitlemise, often translated as CO2 management or CO2 utilization, refers to the processes and technologies aimed at capturing, handling, and repurposing carbon dioxide emissions. This field is gaining increasing importance as a strategy to mitigate climate change by reducing the concentration of greenhouse gases in the atmosphere.

The primary goal of CO2käitlemise is to prevent CO2 from entering the atmosphere, where it contributes to global warming. This can be achieved through various methods, including direct air capture (DAC) technologies that remove CO2 from ambient air, or point-source capture from industrial facilities like power plants and cement factories. Once captured, the CO2 can be either permanently stored or utilized in different applications.

Permanent storage, often referred to as carbon capture and storage (CCS), involves injecting captured CO2 deep underground into geological formations such as depleted oil and gas reservoirs or saline aquifers. This method aims to isolate the CO2 from the atmosphere for extended periods.

CO2 utilization, on the other hand, involves using captured CO2 as a feedstock for various industrial processes. This can include the production of chemicals, fuels, building materials, or even in enhanced oil recovery. The aim here is to create value from the captured CO2 while also potentially reducing the carbon footprint of these products and processes.

The development and implementation of CO2käitlemise technologies are crucial for achieving global climate targets. Research and innovation continue to focus on improving the efficiency, cost-effectiveness, and scalability of these methods to make them viable large-scale solutions for climate change mitigation.
