Environmental damage due to the emission of greenhouse gases from conventional coal-based power plants is a growing concern. Various carbon capture strategies to minimize CO2 emissions are currently being investigated. Unfortunately, the efficiency drop due to de-carbonization is still significant and the capture rate is limited. Therefore three future hard coal IGCC concepts are assessed here, applying emerging technologies and various carbon capture approaches.The advanced pre-combustion capture concept is based on hot gas clean-up, membrane-enhanced CO conversion and direct CO2 condensation. The concept reached a net efficiency of 45.1     «
