Germany has 7,100 biogas plants, according to Fachverband Biogas e.V., the country's biogas association. In 2011 they had a combined capacity of about 2780 MW and contributed about 3.1 per cent of the nation's energy mix. But the sector must adopt new production methods to meet its baseload potential, claims Biogas Pirates, a firm active in Schleswig-Holstein in northern Germany which specialises in the construction and servicing of biogas plants.
