Project Aims and Activities

Project aimes

The main aim of the project is to contribute to the research on application of Carbon capture and storage (CCS) in the Czech Republic. In accordance with the requirements of the European Commission and the SET-Plan (European Strategic Energy Technology Plan) the specific aim of the project is focused on (i) the research and the verification of CO2 capture technologies using high-temperature carbonate loops in laboratory conditions and (ii) the preparation of pilot plant design documentation for its construction on this principle. At the same time, the project contributes to the creation of a knowledge- and personnel-base for CCS processes in the Czech Republic.
