Our energy generation facilities

 

In view of the global gas and oil shortage, it is becoming increasingly important to rely on renewable resources. For us, environmentally friendly and regional energy sources are also important since connecting economic efficiency with environmental protection and regional commitment have always been part of our corporate goals.

How does a biogas plant work? 

In this video, Andreas Müller (Manager Biogas Jena Beteiligungs GmbH) describes the functions of the biogas plant. On the example of the biogas plant Jena-Zwätzen, he explains which steps are necessary for generating warmth from bio mass.

Natural Gas

Combined heat and power plants (CHP) follow the principle of combined heat and power (CHP). They can reliably supply individual buildings or city districts with heat. Cogeneration stands for rational energy use and thus also for climate and environmental protection. CHP plants make double use of the energy input as the waste heat created during the generation of electricity production is utilized for heating.
