Regulation and innovation in biogas technology in selected European countries

The development of biogas plants shows differing structures and levels in Denmark, Austria and Germany. Every country had made specific efforts to promote biogas plants which differ in the political targets, approaches and initial situation. However, in all countries, it can be stated that the most important incentive to invest in and build a biogas plant is related to regulations concerning the long-term guaranteed payments of electricity produced in biogas plants.
