In the electric power sector, they increase generation costs by about 40-50% for natural gas and coal-based power plants. Expressed in terms of costs per unit of CO<sub>2</sub>, this is equivalent to about 35-45$/tCO<sub>2</sub>. Similar cost levels are assumed for industrial sources. CO<sub>2</sub> transport costs were estimated for each region and storage category on the basis of the distance between the main CO<sub>2</sub> sources (industrial centres) and storage sites (Hendriks et al., 2002a). The estimated transport costs vary from 1-30 (2005)$/tCO<sub>2</sub> – the majority being below 10 (2005)$/tCO<sub>2</sub>. Finally, for each region the potential for 11 storage categories has been estimated (in empty and still existing oil and gas fields, and on and off shore – thus a total of 8 combinations); enhanced coal-based methane recovery and aquifers (the original aquifer category was divided into two halves to allow more differentiation in costs). For each category, storage costs have been determined with typical values around 5-10 (2005)$/tCO<sub>2</sub> (Hendriks et al., 2002a). The model uses these categories in the order of their transport and storage costs (the resource with lowest costs first). | In the electric power sector, they increase generation costs by about 40-50% for natural gas and coal-based power plants.
