The hydrogen fuelling station at Munich airport

For the first time worldwide an innovative hydrogen infrastructure has been installed at Munich airport for the operation of airfield busses and passenger cars. In line with the project the suitability for daily use and economy of hydrogen as energy source is researched. This includes the production and storing of gaseous hydrogen (GH2), the fully automatic fuelling of liquid hydrogen (LH2) and the application of airfield busses under the strict safety requirements of the airport procedure.

Associates of the project

ARGEMUC, a cooperation of 15 companies, has initiated the hydrogen project at Munich airport in 1997. Presently, the following companies are part of it:

  • Siemens AG: Control and safety technology
  • MAN Nutzfahrzeuge AG: Pressure accumulator, airfield busses
  • Howaldtswerke - Deutsche Werft AG: Metal hydride storages
  • MTU GmbH / GHW GmbH: Electrolyser
  • m-tec Gastechnologie GmbH: Gas fuelling system
  • TÜV Süddeutschland Bau und Betrieb GmbH: safety-related monitoring
  • Grimm Aerosol Technik GmbH & Co. KG: Sensors
  • ET – EnergieTechnologie GmbH: Project management
  • Linde Gas AG: LH2 supply
  • Bayern Gas GmbH: Innovative natural gas reformation
  • Flughafen München GmbH (FMG): Project infrastructure
  • E.ON Bayern AG
  • Proton Motor GmbH: Forklift with fuel cell

Project description

The constructed hydrogen infrastructure contains a pressure electrolyser for the production of GH2, storages and fuelling stations each for GH2 and LH2, a LH2 evaporator, a fully automatic tank robot for LH2 as well as a superior control technology. The newly developed pressure electrolyser produces GH2 out of demineralised water. With a capacity of 450 kW it produces approximately 94 standard cubic metres of hydrogen per hour, which is stored in metal hydride storages. In connection with a special heating- and cooling system this metal hydride storage makes sure that the downstream compressor can always be operated with a continuous intake pressure, even at unsteady hydrogen production from the electrolysis. The compressor takes the GH2 to the filling pressure of the high pressure accumulator. From there it reaches the vehicle storages of the busses over the petrol pump. In the motors of the airfield busses GH2 is combusted to water. For LH2 a tank of 12,000 l is available. At the LH2 fuelling station passenger cars are fully automatically fuelled by a robot. In the project phases II and III Aral will establish a GH2 petrol pump for vehicle pressure tanks up to 350 bars. For the LH2 system BMW develops and tests an innovative fuelling plant as well as a fuel cell APU. Linde improves the LH2 vehicle tank and the coupling of the tank. In a new fuel cell forklift of Proton Motor the braking energy is stored. MAN develops two low-floor busses with fuel cell drive and a hydrogen combustion engine. Bayerngas supports the construction of an innovative natural gas reformer for the on-site hydrogen production.
