About the Project

The major goal of the SCARLET project was to obtain reliable information and tools for the scale-up and pre-engineering of a 20 MWth CCL plant by continuous self-sustaining operation of an upgraded 1 MWth pilot plant at TU Darmstadt.

The project should provide technical, economic and environmental assessments of this promising technology, as well as the fundamental expertise needed for the scale-up and integration of pre-commercialisation CCL facilities. By addressing these key challenges and demonstrating the upgraded technology at the TU Darmstadt pilot scale of 1 MWth, the project should give confidence for investments into a larger-scale unit, i.e. 20 MWth. After successful demonstration of units of this size, the technology will be ready for design and installation of commercial size units on utility boilers and other sources where CO2 reduction is required. The following key objectives were addressed for the SCARLET project:

  • Identification of the key process parameters and control strategies for the 1 MWth CCL pilot plant fuelled by hard coal and by lignite.

  • Development of scale-up tools and guidelines for CCL reactor design and process layout, validated by experimental data of the 1 MWth pilot plant

  • Design, cost estimation, and health, safety and technical risk assessment of a 20 MWth CCL pilot plant to be built at the Emile Huchet Site of Uniper France.

  • Techno-economic analysis of CCL application to hard coal and lignite fired power plants as well as cement and steel industry at commercial full-scale.

  • Environmental impact analysis of CCL application to hard coal and lignite fired power plants as well as cement and steel industry at commercial full-scale
