ABSTRACT. The article describes the possibilities for the transport of hydrogen in gas networks mixed with natural gas. Options are described for hydrogen production using alternative energy to meet the Green Deal criteria. The specifics of the transport and distribution gas pipelines in Bulgaria are 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, a SWOT analysis was made regarding its impact on gas distribution and transport systems.
