The Association of the German Gas Industry has awarded this year's Innovation Prize in the "Mobility & Transport" category to the pilot test of a passenger bus that is used at the airport and runs on liquid methane.

The project has now been honoured at a ceremony at the House of Innovation in Berlin.

At Munich airport, Gas Innovations for the Energy Turnaround were developed in co-operation with the start-up company CM Fluids from Rohrbach. Together with other partner companies, the award winners have realised a particularly innovative drive concept for the passenger bus and thus successfully implemented ideas for a sustainable and environmentally conscious mobility of the future.

As part of the highly promising pilot project at Munich, a passenger bus originally powered by diesel from the airport's vehicle fleet was converted to a climate-friendly drive system using liquid methane and thus made fit for the future. With the patented drive concept CMF drive, the bus was equipped with a generator-electric drive. The passenger bus is powered by a combustion engine and will in future be fuelled with regeneratively produced biogas. The energy generated by the engine is temporarily stored in a buffer battery, which in turn supplies the bus' electric drive axle with electricity. After the successful conversion, the bus will be particularly energy efficient and even climate neutral when refuelled with biomethane.
