This article analysesthe Japanese and Danish biogas sector as a multiple case study with the purpose of enhancing biogas deployment within the two countries, which have almost the same numbers of biogas plants implemented within the agricultural sector. The two cases are analyzed in respect to their: ‘Production and use of biogas for energy services’,‘Utilization of digestate’,‘Framework conditions supporting the biogas sector’and finally, ‘Current trends in the biogas development’. To support the analysis twobiogas plantsin Japan andthree inDenmark were visited respectively. It is, among others, found that support by various stakeholders are needed to e.g. improve the utilization and distribution of digestate in Japan, and that requirement of higher energy efficiency onnew biogas plants would be favorable, asfor example Combined Heat and Power (CHP) production. At the same time a more systematic mapping of markets for export of energy are needed due to limited district heating (DH). In Denmark, new regulation supporting e.g. export of raw biogas is needed, and more emphasis and support to organic biogas plants should be considered to expand both biogas dissemination and organic agriculture.
