Prospects and Potential for Biomethane Production in Ukraine

Анотація

Prospects and potential for the development of biomethane production in Ukraine are presented. The biomethane potential due to anaerobic digestion from the most prospective feedstock types is estimated as 9.7 billion m 3 CH 4 / year in 2020. At the level of regions of Ukraine, 60% of the potential for biomethane production is concentrated in all regions of the central part of country (Vinnytsia, Cherkasy, Dnipropetrovsk, Poltava and Kirovohrad regions), two regions of the northern part of Ukraine (Kyiv and Chernihiv regions), one region of the western part of Ukraine (Khmelnytsky region) and one region of the eastern part of Ukraine (Kharkiv region). Comparative analysis of two main renewable gases -biomethane and green hydrogen -has been carried out. It is shown that greatest prospects are associated with combination of biomethane and green hydrogen advantages, which involves the conversion of hydrogen into methane with subsequent supply to distribution or main gas networks. The use of such a scheme will allow in addition to AD potential of biomethane to add 6.8 billion m 3 /year of synthetic methane, which can be obtained from methanation of CO 2 from biomethane plants and green hydrogen.The total biomethane production in Ukraine could reach 1.0 billion m 3 /year in 2030. It is expected that biomethane could partly be exported to the EU. The rest could be utilized locally for combined heat and electricity generation in CHP units, heating and industry applications and for transportation purpose. In such a way biogas sector could serve the growing demand in sustainable and clean energy from the transport and industry sectors.
