Carbon capture and storage (CCS) is a technology designed to reduce greenhouse gas emissions, particularly carbon dioxide (CO2). It involves capturing CO2 produced from sources like power plants and industrial processes before it enters the atmosphere. The captured CO2 is then transported and stored underground in geological formations, preventing it from contributing to climate change. CCS plays a crucial role in efforts to mitigate global warming by allowing continued use of fossil fuels while minimizing their environmental impact. It can also be integrated with renewable energy systems, enhancing overall sustainability and helping countries meet their climate goals.
