Abstract
This chapter presents an analysis of the IEA Secretariat regarding the future role of CO2 capture and storage (CCS). It is based on a bottom-up model of the world energy supply and demand and has a number of unique features that are lacking in other energy models, such as a detailed representation of global energy supply and demand, and a technology database based on information from the IEA network. The input dataset used by the model is based on the information obtained from over forty international research frameworks (Implementing Agreements) working under the auspices of the IEA. In the ETP model, the world is divided into 15 regions. Each region is characterized in detail. For example, the regional potential of renewable energy is based on Geographical Information Systems (GIS) analysis. Not only the energy demand, but also the energy supply is endogenous in this model. As a consequence, demand side measures influence energy supply. This can be important if, for example, CO2 Enhanced Oil Recovery is widely introduced and more oil is extracted due to availability of cheap CO2.
