Traffic-related emissions of CO2, nitrogen oxide and particulate matter particularly in urban areas are too high. This one the one hand contributes to global warming and on the other hand harms the health of inhabitants. We have developed an economical and efficient one-stop-shop solution for this problem: We offer the retrofitting of diesel buses with our innovative and patented CMF Drive and and the same time offer the supply with CO2-neutral liquid CMF Biomethane. Our CMF Drive is a serial hybrid drive train comprising of a small gas engine operated at maximum efficiency that charges a small buffer battery with electricity, which in turn supplies an electric drive axle with power and simultaneously serves as a storage for recuperation energy from braking operations. Our CMF Biomethane is liquefied directly beneath the biogas plant and transported to our CMF Drive customers.
