Energy Efficient Considerations on Carbon Dioxide Capture: Solar Thermal Engineering (Part II)

Abstract

As an end user of energy products, carbon dioxide capture and storage (CCS) system commonly requires a significant amount of energy to sustain a steady operation. As a renewable energy source, solar energy can supply plenty of thermal energy in different grades through various types of solar collector. Between the demand and supply sides, several technologies of solar thermal engineering can be applied as a bridge for an energy efficient design.In this paper, a technological framework for the energy efficiency in post-combustion CO2 capture is further discussed as a second section of the two-part study. Based on existing research, several possible options of alternative energy supply to CCS system are analyzed, particularly for solar thermal energy. Moreover, some key design issues for the solar-assisted CCS system, such as integrated solar reactor with the regeneration component, are discussed as well.
