Koltvíoxíðbókun

Koltvíoxíðbókun, also known as carbon sequestration, is a process that involves capturing carbon dioxide (CO2) from the atmosphere and storing it in a stable form. This can be achieved through various natural and technological methods. Natural processes, such as photosynthesis by plants and trees, absorb CO2 from the air. When forests grow or oceans absorb CO2, it is effectively stored. Technological approaches aim to accelerate and enhance these natural processes or create artificial methods for carbon capture and storage.

One prominent technological method is direct air capture (DAC), which uses chemical processes to extract CO2 directly from ambient air. Another approach is point-source capture, where CO2 is captured at its source, such as from industrial facilities like power plants. Once captured, the CO2 can be stored underground in geological formations, such as depleted oil and gas reservoirs or saline aquifers. This underground storage, often referred to as carbon capture and storage (CCS), aims to prevent the CO2 from re-entering the atmosphere.

The primary motivation behind koltvíoxíðbókun is to mitigate climate change. By reducing the concentration of CO2 in the atmosphere, which is a major greenhouse gas, it is hoped that global warming can be slowed or even reversed. Research and development in this field are ongoing, focusing on improving the efficiency and cost-effectiveness of capture and storage technologies, as well as exploring new and innovative methods for long-term carbon sequestration.
