A preliminary infrastructure design to use fossil fuels with carbon capture and storage and renewable energy systems

This paper proposes a design methodology for energy infrastructure to address the recent economic and environmental challenges. The proposed energy infrastructure was based on the recognition that fossil fuels will be used for some time with renewable energy sources because renewables are currently unable to replace fossil fuels entirely. A two-fold strategy for the energy infrastructure design is proposed. One is to minimize the negative impact of fossil fuel systems by installing carbon capture and storage (CCS) facilities to reduce greenhouse gas emissions. The other is to accelerate the introduction of renewable energy systems in their place. The design of integrated energy infrastructure is transformed as a Mixed Integer Linear Programming (MILP) problem. Cases of installing CCS and H₂ as a renewable energy source in Korea are illustrated with a discussion of the systematic design of energy infrastructure.
