FCH2RAIL presents results on the Transport Research Arena Conference in Lisbon (TRA 2022)
16.11.2022
At the heart of the FCH2RAIL project is the modular character of the fuel cell hybrid power pack. In the paper The FCH2RAIL Project: A Demonstration of a Modular Fuel Cell Hybrid Power Pack, a methodology is proposed which is deployed to identify feasible block sizes for the fuel cell and battery. A work flow is presented that includes a dynamic longitudinal vehicle simulation and a fuel cell hybrid propulsion system dimensioning. The results obtained are statistically evaluated and compared against commercially available component sizes.
FCH2RAIL deliverable D7.1 - Gaps in regulatory framework prior to the demonstrator train test
11.10.2022
This deliverable documents the results of the first Legislative Gap Analysis. The aim is to identify any gaps within the current regulatory framework, from a theoretical point of view, before testing and commissioning the demonstrator train on the railway. The gaps that were found are divided into specific fields of application: related to the train, to the refueling station (HRS), to the pantograph and to the infrastructure.
Regarding the train, gaps have been found in both the specific regulations aimed at railway systems and those from other industries. Regarding the pantograph, gaps that highlight the interaction of the pantograph with the electrical power line have been identified. This pantograph-catenary-interaction may cause electric arcs that represent an ignition source and can cause a fire. Gaps for hydrogen refuelling stations (HRS) have been found in ISO 19880, and also a lack of standards regarding hydrogen refuelling protocols for heavy-duty vehicle was noted. Within the Technical Specifications for Interoperability (TSI) environmental protection, fire safety on tunnels, ventilation systems and the definition of requirements for refuelling equipment have been identified as most important gaps.

FCH2RAIL publishes review paper on hydrogen storage and refueling in the rail sector
17.09.2022, International Journal of Hydrogen Energy
The paper Review and comparison of worldwide hydrogen activities in the rail sector with special focus on onboard storage and refueling technologies investigates hydrogen storage and refueling technologies that were used in rail vehicles over the past 20 years. Details of the currently available technology and its vehicle integration are presented, from a total of 80 international studies. Corporate announcements as well as vehicle and refueling demonstration projects were evaluated with regard to storage and refueling technology, pressure level, hydrogen amount and installation concepts inside rolling stock. Furthermore, current hydrogen storage systems of worldwide manufacturers were analyzed in terms of technical data.
FCH2RAIL presents results on World Congress of Railway Research (WCRR 2022)
09.06.2022, World Congress of Railway Research, Birmingham
The paper The EU Project FCH2RAIL - Fuel Cell Hybrid PowerPack for Rail Applications gives an overview of the FCH2RAIL project and the technical developments related to the innovative Fuel Cell Hybrid PowerPack (FCHPP). This modular and scalable power source starts with the ambition to be suitable for newly developed rolling stock as well as for retrofitting of existing electric and diesel trains.

The paper Bi-Mode Hydrogen Train Requirements Using Geospatial Line Assessment summarises the analysis of use-cases of bi-mode multiple units with a fuel cell hydrogen powerpack; based on this analysis it identifies vehicle requirements arising from infrastructure and operation. For this, the authors developed a methodology combining a geospatial assessment on available open data (i.e. Open Street Map and a digital elevation model) and a longitudinal dynamic simulation model of rail vehicles.

FCH2RAIL deliverable D1.1 - Report concerning line and use case based requirements
31.03.2022
This deliverable is describing the analysis and gathering of requirements on hydrogen trains from operational and infrastructural parameters. This is done within two steps. First a high-level line analysis is performed to collect infrastructural and operational characteristics for various countries in the European Union. In the second step, representative use-cases are identified and simulated to evaluate detailed requirements on the FCHPP.
