Abstract:
The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety in Germany has been giving biogas power a key-role as balancing electricity. It can supply power only when needed to balance intermittent renewable energy sources such as wind or photovoltaic electricity. But currently conventional biogas plants are operated continuously and at a high rate of full load hours. Otherwise biogas plants are also forced to limit their electricity production and have to flare the surplus gas in the case of insufficient gas storage capacity, in order to ensure power system stability and reliability during high feed-in periods from wind and solar energy. However, these modes of operation are not in compliance with the requirements of an electricity grid based on renewable power generation. Technology development is still needed for many plants to reach the necessary flexibility. Two exemplary projects funded by the German Federal Ministry for the Environment in the program for “Promoting Projects to Optimize the Use of Biomass for Energy Production” are developing systems for the controllable generation of electricity by biogas plants to meet consumer demands. The projects are described below.
