studies of hydrogen-powered trains, including Alstom's Coradia iLint and Siemens mobility along with
NPROXX, HYBARI and the FCH2RAIL project provide practical insights into current
implementations. The study shows that light trains can utilize compressed gas storage at 350-700 bar
pressure, with a storage capacity of 40-75 kg H₂ and refueling rates of 2-3 kg/min. These specifications
are driven by space and weight constraints specific to light trains. The research also addresses the
economic and safety considerations crucial for deploying hydrogen storage systems at scale. Ultimately,
this study aims to inform industry stakeholders and policy makers about the potential of hydrogen
storage technologies and their implications for the future of sustainable rail transportation. (Less) - Popular Abstract

- As there is an increasing demand to reduce greenhouse gas emissions, hydrogen emerges as a promising alternative fuel for rail transportation. This study explores innovative hydrogen storage solutions for light trains, focusing on both onboard and offboard systems. These trains run on hydrogen, providing a greener alternative to traditional diesel-powered locomotives. The study delves into different storage technologies, such as compressed gas and liquid hydrogen, and highlights important design parameters like storage capacity, pressure levels, and refuelling rate. They are important for integrating hydrogen into rail systems and thereby offer a sustainable path. The shift towards hydrogen-powered trains is driven by the need to combat climate change and reduce reliance on fossil fuels. Hydrogen fuel cells produce only water vapor as a by-product, making them an attractive solution.
The thesis examines case studies like Alstom's Coradia iLint and Siemens Mobility's projects to provide insights into current implementations. These projects use Type IV cylinders at 350 bar pressure which are engineered to be compact and light weight, and suitable for light train application. An analysis is carried out using data from the literature and different industrial reports to understand the relation between the identified important parameters. The analysis shows that with each 1-bar increase in pressure, storage capacity increases by 0.1 kg per liter for onboard storage and 20 kg per liter for offboard storage. The study also addresses economic and safety considerations essential for large-scale deployment of hydrogen storage technology in light trains. The levelized cost of hydrogen storage in light trains tend to be more expensive for onboard (6€/kg) than off board (2.5€/kg) due to the requirement of advanced technology and materials to manage high pressure while ensuring passenger safety. The findings also underscore the importance of innovative storage solutions in advancing sustainable mobility. It is important to acknowledge that the findings are based on a limited dataset due to the non-availability of certain relevant data. A more extensive database would allow for deeper analysis, leading to even more accurate and comprehensive results. However, the study provides a solid foundation for the usage of hydrogen storage in light trains and thereby contributes to the ongoing pursuit of sustainable rail transportation. (Less)
