Bergheim-Paffendorf biogas plant

innogy has been operating a state-the-art biogas facility in Bergheim-Paffendorf since early 2016. A wide range of locally produced renewable resources is used to generate the gas: whole-plant, grass and corn silage, green rye, sugar beet and alfalfas. New energy plants like the cup plant and wild flowers are also tested in the facility.

Biogas plant as a test location for innovative photovoltaic film

The generated raw biogas is refined to natural gas standard and then fed into the natural gas grid as biomethane, enough to supply approximately 3,300 households with electricity or heat. The plant thus makes an important contribution towards supplying the region with climate-friendly energy.

The facility is also a test location for an organic solar film. The film has been attached to two of the three fermenters. The insights gained from these tests are aimed at further developing organic photovoltaic film. Compared to conventional photovoltaic modules the film is less than a millimetre thin, light and flexible.
