              Today and in the future, our focus is on developing and implementing system solutions for producing energy from climate-neutral regenerative fuels: such as combined heat and power systems (CHP) for biogas.

              The principle of a CHP system based on biogas is simple: biogas is generated during fermentation of organic material and collected. It is then used by a cogeneration system to create heat and power to be used locally or fed into the national power grid (as provided for by the Renewable Energy Act in Germany). The generated heat can be used during fermentation processes or to heat commercial buildings or residential areas.

This process provides a virtually free source of energy that can be utilized to generate electricity using MTU Onsite Energy cogeneration systems.

                                    MTU Onsite Energy gas engine generator sets offer tremendous efficiency, cost savings and environmental benefits. In addition to generating electricity, our systems can reduce the odor nuisance and fire and explosion hazards. It eliminates the threat of gas migration and enables landfill sites to be re-cultivated quickly.

                                    A single energy source makes a plant fully independent. Its energy supply is guaranteed in a remote location or if local grids are unreliable. MTU Onsite Energy gas engine systems are portable containerized units, offering the flexibility to relocate the system and tap into new sources of gas. And for landfill sites in Europe, the electricity can be sold for use in the public grid.

                                  • Sewage and water treatment plants remove physical, chemical and biological contaminants from wastewater. Due to the essential nature of these facilities, reliable power is a critical component to maintain 24/7 operations. To support these installations, MTU Onsite Energy offers diesel generator sets covering the complete power range, and featuring industry-leading reliability and availability.


                                    While MTU Onsite Energy diesel systems provide backup and standby power 24/7, our CHP modules provide one of the most economical ways for sewage plants to utilize waste energy. Sewage gas, much like landfill gas, is freely available fuel onsite and highly efficient. From about 6m³ of sewage, MTU Onsite Energy systems generate an average of 1 kWe of electric power and 1.2kWe of thermal energy.

                                    The electric power generated by the system can be used to supply the sewage plant itself or it can be fed into the electric grid. And the thermal heat generated inside the engine during the combustion process can be utilized for heating up the sewage sludge in the digester or for heating the whole facility. In large-scale plants, excessive high-temperature heat may be available that can be used to pasteurize or dry the sewage sludge.
