During the first period of the project, the consortium focused its efforts on the following activities:
-Definition of specifications: The technical specifications for the overall high-pressure value chain were defined, establishing the scope for seamless integration of all components along the hydrogen distribution chain.
- Safety and permitting: A robust safety plan was developed, establishing a joint safety approach across all developments. An initial Preliminary Hazard Analysis (PHA) was performed, covering all system parts — the metal hydride compressor (MHC), trailer, mechanical compressor, buffer tanks, high-pressure compressor, and the various supply infrastructures. These analyses involved working sessions with 13 experts from different project partners. More than 70 safety scenarios were reviewed. Comprehensive safety studies covering all project components were also launched, providing the foundation for detailed HAZOP (Hazard and Operability) studies at subsystem level, which are currently underway. The HAZOP for the MHC has already been completed. In parallel, administrative procedures for demonstration site permitting have been launched which led to the selection of a suitable site.
- Subsystem design: The design of the HYGHER value chain subsystems has advanced, including the innovative metal hydride compressor, two high-pressure trailers, and the filling center. A key achievement of Period 1 is the completed design of the high-pressure trailers. In addition, laboratory benchmarking was carried out to optimize the MHC design, and a manufacturing plan was developed to enable efficient assembly in Period 2.
- Common assumptions and models: Extensive collaborative work was undertaken to establish common assumptions, scope, and models for the various analyses within the project (e.g. circularity, life-cycle assessment, techno-economic analysis). This included the collection of state-of-the-art information and partner data, particularly concerning the most innovative components of the high-pressure value chain. A major achievement was the successful completion of Milestone 11: “Circularity strategies established for three subsystems.”
- Communication, dissemination, and networking: The consortium created a project identity and defined an overarching strategy for communication, dissemination, and exploitation. Networking activities included participation in trade fairs and exchanges with the advisory committee.
