How to use excess heat from the electricity generation of remote biogas power stations? Can the excess heat contribute to the climate protection? The German Ministry of the Environment is supporting a pilot project in the rural district Landsberg am Lech that develops a mobile heat supply system based on excess heat. The heat of the biogas power stations is distributed in a flexible way to different users, including a retirement home and a high school. Due to the distance between the station and possible users, a heating network would be uneconomical. According to a calculation and taking into account the transport energy more than 600 tons of CO2 emissions can be annually saved by the project.
