| Abstract | The paper announces that the Ministry of Energy and Environmental Protection of Ukraine has developed the "Ukrainian Green Deal ", the ambitious goal of which is the transition to a climate-neutral economy, reducing greenhouse gas emissions and decarbonizing the economy by 2070. The "European Green Deal " provides for the achievement of similar goals by 2050. It is mentioned that the share of biomethane and "green " methane in the overall system of transmission and consumption of natural gas is planned to increase. The process of biomethane production by biogas enrichment and carbon dioxide separation is described. The perspective course of pure hydrogen production by water electrolysis due to the use of excess "green " energy from solar and wind power plants is noted. The way of complex integration of biomethane and "green " hydrogen production is suggested. The process of "methanation ", i.e. the conversion of "green " hydrogen and carbon dioxide as a waste product in the production of biomethane is described. The readiness of the NAAU to accredit verification bodies of greenhouse gas emission due to the introduction of the greenhouse gas emission allowance trading in Ukraine was stated. The calculation of the combustion heat values, density and Wobbe number for natural gas when mixed with pure hydrogen has been simulated. It is pointed that when the heat of combustion decreases and exceeds the permissible limits, the Wobbe number does not exceed the minimum set value, which indicates the absence of the need to replace gas-consuming equipment. It is argued that if it is necessary to increase the combustion heat of a mixture of natural gas with hydrogen, it is necessary to enrich it with "heavy " hydrocarbon gases. |
