These essential components will ensure quick and efficient refuelling of hydrogen-powered trains.From Vision to Reality: First Hydrogen Train TrialsIn April 2025, Indian Railways began trial runs of its first hydrogen-powered train on the 89-kilometre route, which spans between Jind and Sonipat.A senior official at Indian Railways has stated that the preliminary trial runs have been primarily successful. However, during the testing of the train, it was identified that the capacity of its hydrogen fuel cell must be increased to enable optimal performance under maximum load-carrying conditions.An estimated additional timeframe of 2 to 3 months is required for technical adjustments and testing. This delay has already pushed back the original launch timeline of December 2024. The railway now aims to introduce the train on the iconic Kalka%u2013Shimla route by mid-2025.The Global Shift Toward HydrogenPowered Trains: A New Era in Clean Rail Transportation1. Germany: Alstom Coradia iLintCoradia iLint stands as the world%u2019s first train that runs on hydrogen-based fuel. The train was developed by Alstom at its Salzgitter facility in Germany.The train was first introduced at the InnoTrans event in Berlin in 2016 and began commercial operations in Germany by 2018.The Coradia iLint represents the inaugural passenger train that employs a hydrogen fuel cell to produce electrical power for traction purposes.. This train operates without emitting carbon dioxide (CO2) and produces only water as a byproduct.On Thursday, September 15, 2022, the Alstom Coradia iLint achieved a noteworthy milestone by successfully travelling 1,175 kilometres without requiring refuelling of its hydrogen tank.2. UK%u2019s: HydroFLEXHydroFLEX is the UK%u2019s first hydrogenpowered train, developed by fitting a hydrogen fuel system onto an existing Class 319 train. The Hydroflex initiative is a joint project between the University of Birmingham%u2019s Centre for Railway Research and Education (BCRRE) and Porterbrook.The idea for HydroFLEX was first introduced at the Rail Live event in June 2018. A working version of the train was later showcased at the same event in June 2019, held at the Quinton Rail Technology Centre.The goal of the project is to help reduce carbon emissions on the UK rail network by replacing diesel-only trains with hydrogen-powered ones by 2040. It supports the UK Government's goal of reducing carbon emissions by 80% by 20503. Swiss: Stadler FLIRT H2The FLIRT H%u2082 train is an electric multiple unit incorporating hydrogen fuel cell technology, developed by the Swiss manufacturer Stadler Rail. Stadler unveiled the FLIRT H%u2082 to the public at InnoTrans 2022 in Berlin. In March 2024, Stadler%u2019s hydrogenpowered train set a Guinness World Record for covering the longest distance without needing to refuel or recharge.This remarkable feat involved the FLIRT H%u2082 covering a distance of 1,741.7 miles (2,803 kilometres), which signifies a pivotal advancement in the implementation of clean energy solutions within the railway sector.4. China: CINOVA H2The CRRC CINOVA H2 is a hydrogenpowered intercity train manufactured by CRRC Qingdao Sifang Co. Ltd,. It was introduced at InnoTrans 2024 as China%u2019s first smart intercity train running on hydrogen.The CINOVA H2 runs on a powerful and efficient hydrogen fuel cell that produces electricity by combining hydrogen and oxygen. The only byproduct is water, which is purified and reused onboard to serve passengers' water needs.COVER STORY
