Restrictions on the planet's carbon footprint are becoming a motivating measure to limit the use of fossil fuels in the European Union. One of the measures to decarbonize the economy is to reduce the use of hydrocarbon fuels (oil, gas, coal). Increasing the potential for hydrogen use in energy is a key point in the conversion of fuels into energy. How the concentration of hydrogen is reflected in the gas supply is an analysis that the energy sector must consider to determine the safe operation and quality of operation of the appliances. Increasing the concentration of hydrogen in gas mixtures by up to 5% does not change the key parameters that determine the interchangeability of used gases in the gas industry. At hydrogen concentrations above 15 % in the gas mixtures, the gasdynamic properties of the gas also change, which also affects the design parameters of the gas supply systems. The article has described the possibilities for transport of the hydrogen in gas networks mixed with natural gas. Options for hydrogen production using alternative energies to meet the Green Deal criteria are described. The specifics of the transport and distributed gas pipelines in Bulgaria have been examined. According to their technical parameters, with the aim of high safety, a scheme of mixing hydrogen with natural gas is proposed. Based on the materials of the pipelines and the technical means of management and maintenance, the permissible concentrations of hydrogen are given. To achieve the possibility of a simplified assessment of the influence of hydrogen.

The author expresses his sincere gratitude to the gas companies from the "Natural Gas" Association, who accepted the topic of decarbonization and environmental protection as their mission and, in this sense, provided full support and sympathy for the conducted research and analysis. We gratefully accept proposals for follow-up activities and results, believing that real results in scientific activity can only be obtained if they are related to applied projects that benefit society as a whole.
