Even if rail transport is a low carbon emission mode of transport, 20% of rail operations are done by diesel traction in France. SNCF, the French historical railway operator, is investing in the decarbonization of the fleet with the development of hydrogen and battery trains, which present different performances than current diesel or electric rolling stocks. By using a dedicated simulation tool, this paper addresses the diversity of line profiles and operating constraints of a light train with battery and hydrogen traction to map area of relevance and to define the energy and power requirements. It results that there is no one-size-fits-all solution to decarbonize rail transport. Both battery and hydrogen technologies have their relevance in secondary rail networks depending on the technological solutions, infrastructure, and desired transport service.

摘要

Even if rail transport is a low carbon emission mode of transport, 20% of rail operations are done by diesel traction in France. SNCF, the French historical railway operator, is investing in the decarbonization of the fleet with the development of hydrogen and battery trains, which present different performances than current diesel or electric rolling stocks. By using a dedicated simulation tool, this paper addresses the diversity of line profiles and operating constraints of a light train with battery and hydrogen traction to map area of relevance and to define the energy and power requirements. It results that there is no one-size-fits-all solution to decarbonize rail transport. Both battery and hydrogen technologies have their relevance in secondary rail networks depending on the technological solutions, infrastructure, and desired transport service.
