Abstrakt: In the energy field hydrogen will be more obvious to use by certain technologies than by direct combustion. The paper presents a conceptual analysis on the use of hydrogen by hydrogen by hydrogenation of carbon dioxide with final product methane, by hydrogenation of carbon dioxide, with the final product of methanol and by injection in certain proportions into the natural gas network. A new application of carbon dioxide hydrogenation is the decarbonisation of flue gases. To this end, conceptual analyses have been carried out for the capture of CO2 from flue gases, including through cascading energy production, required by a significant decrease in pollution. The experimental development for the hydrogenation of carbon dioxide with an experimental pilot plant shall also be submitted. At the same time, the pressure and temperature conditions for the methaneization plants are also presented. References are also made to catalysts of the latest generation, for a high efficiency of the respective hydrogenation processes. With regard to the hydrogenation of carbon dioxide from flue gases, the effect of water vapor and oxygen on the overall efficiency of the process shall also be clarified. By converting carbon dioxide into combustible substances, an important step towards transforming it into an energy vector is taken. This reduces expenditure by storing it and important steps are taken towards a circular energy. [ABSTRACT FROM AUTHOR]
