Project idea

Development of a simulation model that

The model has been developed to simulate hydrogen refuelling stations and systems. In contrast to other simulation tools, the focus is not on the refuelling process specifically, but on the systemic idea and the consideration and representation of the system-related interactions and conditions, processes and effects.

The model has been developed to appeal to a wide range of users. For this reason, the development has been supported by a large number of companies in the Project Monitoring Committee. These companies work in the fields of plant engineering, instrumentation, valve technology, control technology, refuelling station operation, fleet operation, vehicle construction, etc.

HRS-Modell was originally developed to simulate H2 refuelling stations. HRS-Modell can now be used to simulate any type of hydrogen refuelling station or system. In addition to refuelling stations, these can be refuelling systems for trains, shipping containers, trailers or other individual applications in hydrogen (e.g. defuelling strategies).

In order to be useable for a wide range of users, HRS-Modell has been designed to keep computing times to a minimum. Simple filling processes can be calculated in just a few minutes.

Many companies lack experience with hydrogen and an understanding of the real requirements to their specific component or system. Often they are unaware of the highly dynamic requirements.
1: The model is able to simulate the system on a digital test platform and convey operation conditions.
2: The model provides the ability to simulate systems in a way to understand actual operation conditions and with this functions as a digital test platform.

Basic principle

Individual models

The main components of a hydrogen refuelling station are represented in the simulation tool by individual models. The specific calculation formulae are stored in these modules. The individual models were validated with measurement data from real systems. Within the framework of the funded project, the validation was primarily carried out using measurement data recorded at ZBT’s hydrogen test field. The station’s hydrogen storage, compressor, heat exchanger, pressure regulator, pipes and valves can be used as individual components.

Full system model

From component to system

Based on the individual models, a customised system can be compiled as a full system model and a user-defined calculation can be performed. The full system model allows the user to simulate different configurations, operating strategies and application scenarios.
This allows for the modelling and optimisation of both new and allready existing stations. The aim is to contribute to the economic and enegertic efficiency of hydrogen refuelling systems.

The project (Project No 21801 N) was funded under the title
“Entwicklung und experimentelle Validierung von Modellen zur verfahrenstechnischen Auslegung und techno-ökonomischen Bewertung von Wasserstofftankstellen (HRS-Modell)“
