There is a very limited amount of research presented in the literature that further discusses the conceptual idea of TDM as a pre-combustion capture technology. Therefore, the technoeconomic
analysis presented in this paper produces valuable information.TDM can be applied to produce hydrogen for purposes other than on direct power production, such as upgrading biofuels or for other chemical processes, but this option is not further evaluated in this study. The theoretical background of TDM reaction and carbon black as well as the technical descriptions of the four concepts are given in Section
