ImplaN – Initial Infrastructure for hydrogen mobility based on predictable consumers

Project duration 01.10.2016 – 31.03.2019

Research within the project ImplaN focused on how the number of hydrogen refueling stations in Germany can be increased while also raising demand.

In order to reach its climate protection goals, Germany must lower its CO2 emissions drastically. This also pertains to the transport sector, which produces about 20 percent of Germany’s greenhouse gas emissions. Problems with particulate matter and dangerous gas emissions also show that internal combustion engines should not play a role in transportation in the future. Battery and hydrogen-powered engines are good alternatives, though we still face a problem when changing to these engines: There are no incentives for refueling stations to offer hydrogen as long as there is no demand for it, and potential customers have no incentive to buy a hydrogen-powered vehicle as long as there is no fueling infrastructure available in Germany. This is exactly where ImplaN closes a gap.

During the initial phase of development of a hydrogen infrastructure, calculable customers are especially well-suited. These include vehicles with relatively constant routes and life cycles that are thus easy to plan, such as buses, taxi cabs, and car sharing fleets. If these are hydrogen-powered, refueling stations can count on reliable customers and a station can thus be operated cost-effectively. Especially fleets in contrast to privately owned vehicles require only a locally limited infrastructure, allowing this infrastructure to be developed step by step. Ideally, this development process leads to a refueling station network which will also serve private car drivers well.

During the ImplaN project, concrete solutions for combinations of vehicle fleets and refueling stations were identified. The goal was to attain high cost-effectiveness while creating increased use for private users in order to support the change to hydrogen-powered vehicles in the transport sector overall and to thus lower CO2 emissions.

The project was part of the initiative Hydrogen Power Storage & Solutions East Germany (HYPOS), which aims to promote the use of hydrogen as a source of energy in East Germany. The project therefore focused on the newer German States as model region.

Within the research project, the RLI will focus on the following objectives and tasks:

  • Research and preparation of data
  • Determination of potential demand of fleets in the region of study
  • Identification of potential refuelling station locations
  • Simulation and optimization of a model refuelling station
  • GIS modeling and programming
    • Integration of relevant data in a geo-information system (GIS)
    • Connection of GIS and simulation model
    • Integration of a multi-objective optimization algorithm
  • System optimization of fleet infrastructure with regard to cost-effectiveness and use for private vehicles
  • Evaluation
    • Comparison of different types of regions and demand
    • Determination of potential and cost
    • Derivation of recommended actions for the Hypos region

After the research project has been completed, the RLI concludes the following results:

  • The use of fleets can improve the efficiency of hydrogen refueling stations.
  • By adding 27 H2 filling stations in the new states, 3.5 million additional people can be switched over. This requires annual subsidies of around € 4 million - which is little compared to other infrastructure investments, such as electricity grid expansion costs.
  • In the case of changed framework conditions (such as the hydrogen price or the EEG levy on electrolysis electricity), a profit can also be made.
  • Jena, Dresden and Halle (Saale) are strategically very important. If new hydrogen refueling stations are created here, the network benefits overall.
