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

The lead project TransHyDE is one of three hydrogen lead projects of the BMBF and deals with the development of a hydrogen transport infrastructure. Several hydrogen infrastructure technologies will be developed, evaluated and demonstrated. The other two lead projects are concerned with the development of large-scale water electrolysers (H2Giga) and the production of hydrogen and its downstream products on the high seas (H2Mare).



To overcome the challenges and barriers to the establishment of a hydrogen economy, the TransHyDE flagship project relies on both demonstration projects and research networks. Transport technologies will be tested and scaled up in a total of four demonstration projects. Technologies to be considered include high-pressure vessels, existing gas pipelines, and hydrogen transport using ammonia and LOHC (Liquid Organic Hydrogen Carriers). The research consortia are concerned with the sustainable use of LNG terminals with hydrogen, the establishment of a safe infrastructure through the testing of materials and the development of sensors, and the definition of standards, norms and certifications. In addition, the technical development of the transport chain for ammonia and liquid hydrogen will be examined in more detail.

Fraunhofer ISI is part of the TransHyDE research consortium TransHyDE-Sys - "System Analysis on Transport Solutions for Green Hydrogen". As a cross-sectional project, the system analysis has a special function: On the one hand, essential system knowledge for the time-dependent construction and coupling of energy infrastructures is generated with the help of own modeling and simulation work as well as ecological analyses. On the other hand, observations, analyses and requirements of the implementation and research projects are to be collected, compared with existing knowledge and classified in a comprehensive manner. The results will be incorporated into a continuously evolving roadmap. This roadmap will provide ongoing support for the research and implementation projects, identify possible research and development topics for the next project phases, and provide important recommendations for external stakeholders.



Fraunhofer ISI contributes its expertise in model-based energy system analysis, roadmap generation and actor analysis to the TransHyDE-Sys project to support the development of a hydrogen economy. In the field of energy system modeling, model-based scenarios for hydrogen demand in all application sectors in Germany and Europe will be developed.  Furthermore, model-based scenarios will be developed on how and at which locations the required hydrogen production can take place, taking into account the entire energy system in the EU and neighboring countries. Together with the partners for the grid-side infrastructure analysis, analyses on the development and establishment of a hydrogen economy will be carried out. The aim is to gain a better understanding of the initial hydrogen infrastructures and to describe a possible scientifically and technically justified transformation path towards a climate-neutral energy system. This path should be sufficiently robust to enable a real implementation of the hydrogen transition. These analyses will be accompanied by collaboration on the creation and design of a roadmap for the establishment of a hydrogen infrastructure. One focus is the visioning part, where scenario-based workshops are conducted. The goal of the roadmap is to show where we are, where we want to go and how to get there. The TransHyDE-Sys work is also supported by stakeholder analysis to ensure social relevance. Therefore an actor mapping will be performed to identify relevant actors of a hydrogen infrastructure.
