TransHyDE-Sys – System Analysis on Transport Solutions for Green Hydrogen

The hydrogen lead project TransHyDE will investigate the prospective hydrogen transport infrastructure in Germany. The research project, funded by the German Federal Ministry of Education and Research (BMBF), started in April 2021 and is being worked on by a consortium of over 50 members. FfE is involved in the project as part of the system analysis subgroup (TransHyDE Project Sys).

Hydrogen lead projects

To implement the National Hydrogen Strategy, the German Federal Ministry of Education and Research (BMBF) has launched three hydrogen lead projects. H2Giga deals with the series production of electrolysers and H2Mare investigates hydrogen production on the high seas. FfE is involved in the third lead project TransHyDE, which develops, evaluates and demonstrates hydrogen transport infrastructures. This project is divided into various research associations. In this context, the FfE’s remit exclusively comprises system analysis.

FfE's areas of responsibility in the TransHyDE project System analysis

The FfE focuses on infrastructure development from an actor perspective and energy system modeling (AP 2) as well as roadmapping (AP 7).

As a basis of AP2, regional load profiles of energy generation and consumption are determined with the help of the FfE Regionalized Energy System Model FREM and the sector models for industry (SmInd), transport (TraM), private households (PriHM) and trade, commerce and services (TerM). Along with other techno-economic parameters, these form the data basis for creating European scenarios on the role of generation, supply and consumption of infrastructure-relevant energy sources. Based on this, the integrated simulation model for plant deployment and expansion planning (ISAaR) and the market and infrastructure model of the gas industry (MInGa) can be used to model the necessary infrastructure requirements and system feedback effects. In this way, it is possible to answer the following questions, among others:

  • What is the most systemically beneficial infrastructure for H2 and CO2? What are the specific costs that result?
  • Where does it make the most sense to position electrolysers and methanation plants?
  • Where and how much investment is needed in new and rebuilt hydrogen and CO2 pipelines?
  • How are electricity infrastructure needs evolving?
  • How do the different procurement options (e.g., generation in Europe vs. import) and storage technologies for hydrogen affect the power plant fleet?

In addition, the regional study Trans4In is embedded in this AP, in which a transformation path to CO2 neutrality in the chemical triangle of Bavaria is developed.

In AP4, the results are compared with the results of infrastructure development from a system perspective, which are being developed by the Fraunhofer Institute for Energy Economics and Energy System Technology IEE. A sustainability assessment based on a life cycle analysis as well as a techno-economic analysis will be carried out in AP5.

In the roadmapping (AP7), which represents the second substantive focus of the FfE, the results will be brought together. The development of the H2 transport infrastructure will be outlined separately for the use cases in industry, transport and the energy industry, and the respective research requirements will be identified.

In the processing of the research project, synergies with the Trans4ReaL project, in which real laboratories of the energy transition with a focus on hydrogen technologies and sector coupling are scientifically accompanied, can be used. Especially in the development of the roadmap, it is expected that the exchange with the colleagues:inside is a possibility to concretize the conclusions.

Within the framework of the project, FfE e.V and FfE mbH are working together with, among others, the German Technical and Scientific Association for Gas and Water, the Fraunhofer Institute for Energy Economics and Energy System Technology IEE, Dechema Gesellschaft für Chemische Technik und Biotechnologie e.V., the Fraunhofer Institute for Ceramic Technologies and Systems IKTS, the Fraunhofer Institute for Systems and Innovation Research ISI, izes gGmbH Institute for Future Energy and Material Flow Synthesis, the Fraunhofer Institute for Solar Energy Systems ISE, and the Fraunhofer Research Institution for Energy Infrastructures and Geothermal Energy IEG.
