Linear Models for Optimization of Infrastructure for $\hbox{CO}_{2}$ Capture and Storage

This paper presents linear models of the most common components in the value chain for $\hbox{CO}_{2}$ capture and storage. The optimal investment planning of new gas power plants traditionally includes the cost of fuel versus sales of electricity and heat from the plant. If a new power plant also causes additional investments in gas infrastructure, these should be included in the optimization. With the increasing focus on global $\hbox{CO}_{2}$ emissions, yet another aspect is introduced in the form of technology and infrastructure for capture, transport, and storage of $\hbox{CO}_{2}$. To be able to include all these aspects in the planning of new power plants, linear models for $\hbox{CO}_{2}$ capture and storage are formulated consistent with current models for gas, electricity, and heat infrastructures. This paper presents models for the following $\hbox{CO}_{2}$ infrastructure: source, combined cycle gas turbine producing electricity, heat and exhaust, capture plant, pipeline, liquefaction plant, storage, ship transport, injection pump, and demand/market.
