Carbon Capture and CO2 Sequestration Challenges
Efforts to reduce carbon levels involve complex challenges, such as capturing CO2 emissions from fossil fuel burning and sequestering them underground. Traditional methods like carbon capture and sequestration (CCS) face scalability and cost issues, hindering widespread implementation. However, a new approach in Iceland involving carbon dioxide removal (CDR) shows promise by directly extracting atmospheric CO2 and transforming it into a stable rock form, albeit at a relatively small scale compared to global emissions.
