In the Hydrogen2Hydraulics project, power packs are being developed for hydraulically driven mobile and semi-stationary construction and work machinery that use hydrogen as an energy source instead of diesel in the interests of decarbonization and emissions reduction. Hydrogen is converted into electrical energy by using a fuel cell, which is used to electrically drive a hydraulic pump. The output is hydraulic power for coupling the working units. Hydraulics are still indispensable in this sector due to the high power density and robustness. The system is being designed as a modular system so that different power classes and installation spaces can be served. In the project, the overall system will be designed by modeling and simulation, a prototype with an output of 50 kW will be built and finally tested under realistic conditions. This is a collaborative project between KLEIN GmbH, Gamperl & Hatlapa GmbH Elektrotechnik, Kniele GmbH and the Chair of Construction Machinery at TU Dresden.
The main tasks, which are worked on by the TU Dresden in subproject D "Modeling and (real-time) simulation", are as follows:
- requirements and interface definition,
- creation of a cross-domain simulation model,
- model-based component dimensioning,
- hardware-in-the-loop simulation of real-time total system model (controlled system) and control unit (controller),
- model validation based on measurement data,
- elaboration of a generally valid development tool for the design of universally usable hydraulic units for mobile machines based on fuel cell technology.
