Scientific and Technical Objectives of the HYFleet:CUTE Project

  • Operate 14 Gaseous Hydrogen (GH 2) Internal Combustion Engine buses in regular public transport in Berlin with a target of reaching a 90% reliability of a diesel engine.

  • Demonstrate hydrogen infrastructure through refuelling a fleet of 14 GH 2 buses using on-site GH 2 production via LPG-reforming, as well as on-site liquid hydrogen (LH 2 ) storage and vaporisation.

  • Demonstrate new ways of hydrogen production with low CO 2 emissions by decentralised reforming of hydrogen from the refinery waste product, LPG. The possibilities of CO 2 separation, storage and use in the production process will be carefully investigated to gain a carbon-neutral hydrogen production pathway.

  • Increase the system efficiency of the H 2 station in Berlin through the installation of two stationary fuel cell CHP systems to supply the filling station with heat and electricity from hydrogen surplus and evaporation. The target is to operate two stationary fuel cells from different manufacturers to be able to compare the systems with regard to energy efficiency and reliability.

  • Demonstrate new generations of Hydrogen Internal Combustion Engines (ICE) as a cost effective technology at full scale and to further develop the technology with regard to improvement of the output power and the energy efficiency
  • Demonstrate innovative energy management systems for mobile hydrogen ICE applications, including engine management systems and application of fuel cells for auxiliary power supply, under real life conditions to improve the energy efficiency

  • The HyFLEET:CUTE demonstration project will allow a comprehensive life-cycle assessment of all advanced public transport technologies currently on the market under real life conditions.

  • The HyFLEET:CUTE project aims to reach a price for hydrogen ICE vehicle operation close to the price for current vehicle operation .

  • Increase the degree of technological maturity of the installed CUTE hydrogen infrastructure.

  • Increase the maturity of the current fuel cell technology by operating 21 + 6 fuel cell buses at seven European locations and two locations in Australia and China over 12 months in extreme climatic and technical boundary conditions.
  • Increase the Fuel Cell lifetime by analysing the parameters which influence the lifetime under practical conditions, such as hydrogen quality, influence of temperature etc.

  • Reduce the fuel consumption of Fuel Cell-buses,

  • Development and production of a pre-commercial FC-Hybrid-bus with min. 350bar hydrogen storage technology.

  • Existing infrastructure in Hamburg will be expanded by a new H 2 dispenser for passenger cars.
