This book explores the principles and technologies involved in carbon capture and storage (CCS), a key strategy for reducing greenhouse gas emissions. It introduces methods of capturing carbon dioxide from industrial sources and power plants, followed by its transportation and storage in geological formations. The text examines different capture technologies, including pre-combustion, post-combustion, and oxy-fuel processes. It also discusses environmental, economic, and policy aspects associated with CCS implementation. Emphasis is placed on the role of CCS in mitigating climate change and supporting sustainable energy systems. By integrating scientific knowledge with practical applications, the book serves as a valuable resource for students and professionals in environmental science and energy studies.
