Project: Standards for hydrogen applications

The German Centre for Rail Traffic Research at the Federal Railway Authority has awarded a new development contract: TÜV Rheinland InterTraffic GmbH is to develop a standard for hydrogen applications in rail vehicles. Regulatory and technical specifications are required to ensure the fundamental safety of hydrogen vehicles. To date, the authorities have relied on technical regulations and standards from the automotive industry for the approval process of hydrogen fuel cell vehicles when assessing conformity. Dedicated technical regulations and standards are now to be drawn up for the approval of hydrogen-powered rail vehicles. This should facilitate the use of hydrogen and fuel cell technologies, simplify the approval process and thus promote and sustainably strengthen the use of alternative traction systems in rail transport. The project comprises two work packages. First, all relevant national and international regulations and standards applicable to hydrogen vehicles and fuel cell systems will be reviewed. This will include an analysis of their application to the rail vehicle sector and their evaluation. In a second step, a draft for a railway-specific standard to facilitate the implementation of hydrogen and fuel cell technologies will be developed. The project will last twelve months.
