Abstract
In this study, all contents related to the entire cycle of energy production and use are defined as energy-environmental technologies, and the technical classification and brief technical principles of carbon capture and storage technology (CCS) as energy-environmental technologies are described. In addition, we analyzed the results and actual data of established scenarios and various indicator costs from various perspectives of reports produced by reliable institutions for various energy-environment technologies including the above. Finally, this study aims to lay the foundation for comprehensive research that can understand energy-environmental technology through the establishment of cost-side scenarios and analysis of data with objective approach to energy-environmental technology.
