Alstom wants to optimise hydrogen train refueling

Train builder Alstom signed a partnership agreement to optimise the hydrogen refuelling of passenger trains with Hynamics. The goal is to reduce the time needed to refuel the trains, and thus accelerate the development of hydrogen trains.

Alstom and Hynamics, the hydrogen subsidiary of French multinational electric utility company EDF Group, are already carrying out joint modelling, calculation, and simulation work in teams. This work will be tested from 2022 on the electrolyser test platform at the ‘EDF Lab Les Renardières’, one of three R&D centres of Électricité de France (EDF).

A hydrogen production station, a compressor up to 450 bars and several storage racks will be mobilised to recreate the filling circuits at real size and to evaluate the behaviour of the equipment under optimal observation conditions.

Fueling standard

The ultimate goal is to define an international refuelling standard that will make it possible to limit the time hydrogen-powered trains are not in use during refuelling while complying with the regulations and safety rules in force. This is currently a major issue for both railway companies and passengers, say the partners.

“This partnership will enable us to optimise the hydrogen distribution infrastructure and the rolling stock made available to operators. This is a project that presents many opportunities for the decarbonisation of transportation and the development of sustainable mobility”, the two groups emphasise.
