LOW-EMISSION COAL ENERGY

 

The ÚJV Řež, a. s. Nuclear Safety and Reliability Division coordinates and solves research projects focused on problems related to the capture and storage of carbon dioxide (CCS), originating in the energy sector during the combustion of fossil fuels. We cooperate on projects with universities (Czech Technical University and Institute of Chemical Technology), and with the research facility of the Czech Geological Survey. The topics of projects are consistent with the problems addressed by ÚJV Řež, a. s. under the EERA Joint Programme CO2. The main project is included for the Czech Republic in the SETIS European information system, and the achieved results are monitored by the European Institute for Energy Research.

 

  • CCS problem solving in ÚJV Řež, a. s. includes:
    • Methods and technologies for capture (separation) of carbon dioxide (CO2) in energy generating plants and proposals of optimal integration of the CO2 capture technology into the process technology of power plants;
      • Research and development of optimal concept of CO2 capture from flue gases after fossil fuel combustion in boilers (post-combustion capture). For specified power and fuel, preparation of technical design of the system of CO2 adsorption capture from flue gases and optimal integration of this system into the process technology of power plants. Impact assessment of the integration of capture systems on the economy of operation of power plant and on the production price of electricity;
      • Research and development of optimal concept of CO2 capture from boiler flue gases for the case of combustion with oxygen – oxyfuelcombustion. For specified power and fuel, preparation of technical designs of oxygen combustion boilers. Evaluation of the economy of operation of power plant units with oxyfuel combustion and capture of CO2;
      • Experimental research focused on CO2 separation from flue gases by means of adsorption;
    • Transport of CO2;
    • Storage of CO2 in rock structures:
      • Development of methods for assessing the suitability of a potential repository Evaluation of CO2 migration and interaction with rock environments;
      • Modelling of CO2 migration and interaction with rock environments;
      • Experimental research of CO2 migration and interaction carried out on samples of rocks corresponding to rocks occurring in potential repository sites in the Czech Republic;
      • Risk analysis for safety assessments of CO2 storage;
      • Acceptability of CO2 storage in geological structures to the public;
      • Economy of transport and storage of CO2.
