  Abstract:   This paper investigates the technical aspects of solid fossil fuels decarbonisation by gasification process. More specifically, it focuses on the technical evaluation and the assessment of performance of an Integrated Gasification Combined Cycle (IGCC) scheme modified for Carbon Capture and Storage (CCS). One of the key units of such a plant is the gasification island, a number various commercial gasification reactors (mainly entrained-flow types of dry feed and slurry feed) are evaluated for decarbonisation of fossil fuels (coal). The significant issues in the overall design of fossil fuels decarbonisation process using gasification process are: proper choice of gasification reactor and feedstock (e.g. fluxing or fuel blending), downstream syngas treatment options (shift conversion of carbon monoxide, syngas desulphurization and later carbon dioxide capture) and finally the usage of combustible decarbonised gas for various energy vectors poly-generation (e.g. power, H2 etc.). Finally, whole process for one case study (using Siemens gasification reactor) was mathematical modeled and simulated using ChemCAD software for the particular case of hydrogen and electricity co-production scheme based on coal with carbon capture and storage.
