Aim and Objectives

The major aim of the SCARLET project is to obtain reliable information and tools for the scale-up of the CCL process and pre-engineering of a 20 MWth CCL plant by continuous self-sustaining pilot plant operation. The project shall provide a technical, economical, and environmental assessment of this promising technology, as well as the fundamental expertise needed for the scale-up and integration of pre-commercialisation CCL facilities. The following objectives are defined to reach this aim: The key process parameters and control strategies shall be identified by testing the CCL process in an upgraded 1 MWth pilot plant at Technische Universität Darmstadt with hard coal and lignite as fuel, aiming a target of at least 90 % CO2 capture and an efficiency penalty less than 3.5 % points. Scale-up tools and guidelines for CCL reactor design and process layout shall be developed and validated by experimental data of the 1 MWth CCL pilot plant. The results of pilot testing as well as the developed scale-up tools and guidelines shall lead to the design, cost estimation, and risk assessment of a 20 MWth CCL pilot plant to be built at the Emile Huchet Site of Société nationale d’électricité et de thermique (SNET). Furthermore, the techno-economical and environmental impact of the CCL application to hard coal and lignite fired power plants as well as cement and steel industry at commercial full scale shall be determined.
