Italian rolling stock maintenance company Sitav presented its prototype hydrogen locomotive at the fourth edition of the Hydrogen Expo in Piacenza, held from 9 to 11 June 2025.
Although it is still a prototype, the locomotive has successfully passed the initial stages of the preliminary approval process, which will continue in order to obtain full certification for operational use. The experience gained throughout this innovative project has equipped Sitav with the capability to carry out both modernisations and the construction of new vehicles.
The hydrogen locomotive prototype is designed as a modular vehicle to meet various operational requirements. It is equipped with a remote diagnostics system that monitors the machine’s status and optimises maintenance activities. The vehicle also features energy recovery during braking and uses low-pressure hydrogen for easier and safer refuelling. Its design prioritises optimal visibility to ensure maximum safety in service.
The locomotive has already cleared the early certification phases and is expected to enter service in the near future. This significant milestone has been achieved thanks to the dedication of Sitav’s workforce and the invaluable contribution of key partners such as OMG Manufacturing, BluEnergy Revolution, and Dako-CZ.
Dako-CZ began collaborating with Sitav on this pioneering project, supplying the complete braking system, which includes the brake container, brake cylinders, antiskid devices, and other standard components. The successful integration of these systems reflects the strong coordination and shared vision between the partners.
SITAV has announced that the hydrogen fuel cell locomotive will be showcased at EXPO Ferroviaria, taking place from 30 September to 2 October 2025. The event will provide an opportunity to demonstrate the vehicle’s capabilities and reinforce Sitav’s commitment to innovation and sustainability in rail transport.
The development of the hydrogen shunting locomotive is aimed at providing a modular and scalable solution for the refurbishment of existing vehicles, involving the removal of the diesel power unit and its replacement with a hydrogen fuel cell system. This approach supports the broader decarbonisation goals of the railway sector.
Sitav collaborates with leading organisations and research institutes, including the Italian Electrotechnical Committee (CEI), to advance hydrogen technology for railway applications. The project also underlines the company’s strategic commitment to supporting the transition towards clean and efficient mobility.
