RWE commissions German biogas plant

RWE recently commissioned a state-of-the-art biogas plant in Bergheim-Paffendorf, Germany. The facility has a thermal capacity of 7.4 MW and is designed to feed up to 700 cubic meters into the gas grid per hour.

Raw biogas produced at the plant is upgraded to pipeline-quality gas onsite and fed into the gas grid operated by Thyssengas, making it available to the region’s combined-heat-and-power stations.

According to RWE, the biogas plant is being supplied with a broad mix of feedstock by regional agriculture producers, including grass, maize and wholecrop silage, as well as sugar beet, Lucerne, forage rye and agricultural fertilizers. The use of new types of energy crops, such as cup plant (Silphium perfoliatum) and wild flowers, will also be tested at the facility.

The €13 million ($14.42 million) facility is also being used to test a new solar film, which has been applied to two of the site’s three digesters. The goal is to gain experience and insights that can be used to develop the organic photovoltaic film even further. In contrast to traditional photovoltaic modules, the film is light, flexible and only a few millimeters thick. Completely new areas of application are possible as a result.
