Linear models for optimization of infrastructure for CO2 capture and storage

This paper presents linear models of the most common components in the value chain for CO2 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 CO2 emissions, yet another aspect is introduced in the form of technology and infrastructure for capture, transport, and storage Of CO2. To be able to include all these aspects in the planning of new power plants, linear models for CO2 capture and storage are formulated consistent with current models for gas, electricity, and heat infrastructures. This paper presents models for the following CO2 infrastructure: source, combined cycle gas turbine producing electricity, heat and exhaust, capture plant, pipeline, liquefaction plant, storage, ship transport, injection pump, and demand/market.
