In Germany, most of the biogas plants built between 2005 and 2011 are about to finish the subsidies provided by the law for energy production. How can the continuity of these projects be ensured? The University of Hohenheim conducted research to evaluate a possible solution: grouping multiple biogas plants to channel raw biogas into a single biogas upgrading plant to be injected into the national natural gas grid. The research identified three model sites representing three different regions of Germany, and it was found that with this cluster model, investment costs can be reduced by up to 50% compared to the individual solution.
