The state of the energy complex of Ukraine and its ecological component is consideredin this paper. Data on the prospects for the production of "green hydrogen" due to the use of excess maneuvering capacity of "green energy" and the problems associated with it presented. The issues related to the extension of the service life of Ukrainian nuclear power plants is described.
Prospects for the use of hydrogen in industrial combustion processes, rather than as a process gas, are considered.
Original experimental data on the combustion of natural gas with impurities of different hydrogen concentrations are presented. Data were obtained on the effect of oxidant content on the formation of nitrogen oxides in the flame front of the laminar torch.Influence of the solutions containing hydrogen on process of nitrogen oxides formation and additional oxidation of NO in NO2 in combustion processes is studied and results are presented. The most favorable conditions (concentration of hydrogen solution content and temperature regime) of NO oxidation in NO2 are determined.
Recommendations on the main directions of development of hydrogen energy of Ukraine are given. The need to determine the optimal proportion of hydrogen that may be present in the gas transmission system of Ukraine is emphasized.
