carbon capture and storage (CCS) has been sufficiently documented in existing literature. Below, the main steps are therefore only briefly described. Interested readers are referred to other sources, most importantly to the Special Report on Carbon Capture and Storage recently published by the Intergovernmental Panel on Climate Change (IPCC).1 CO2 can be captured during the process of energy transformation. This is done either prior to combustion, after the combustion process, or using the so called oxyfuel-method. For the latter, combust
