Indian Railways efficiently examined the primary hydrogen-powered coach or driving energy automobile earlier this week at its Integral Coach Manufacturing facility (ICF) in Chennai. This marks a key milestone within the nationwide transporter’s quest to construct India’s first hydrogen-powered practice, one thing just a few railways on the planet have tried, with a bulk of the initiatives nonetheless within the trial part.
The ICF mission is critical for the Railways because it is likely one of the key gamers in India’s mission to scale back greenhouse gasoline emissions and improve the share of renewable power in its power combine. An elevated use of hydrogen, which is a cleaner gas, will additional cut back dependence on fossil fuels.
Officers stated that the mission has reached the ultimate stage, whereby testing of assorted gear is being performed earlier than hydrogen-powered trains are pressed into industrial service.
What’s the mission?
Indian Railways’ Northern Railway zone has undertaken this mission which started in 2020-21. The mission has two main elements. First, the conversion of two typical 1600 HorsePower (HP) diesel energy vehicles into hydrogen gas cell-powered traction system, and second, establishing a hydrogen storage and fuelling facility at Jind in Haryana.
The whole value of the mission is roughly Rs. 136 crore. The first design, validation, and testing is being undertaken by Indian Railways’ Analysis Design & Requirements Organisation (RDSO).
A senior official of the Ministry of Railways stated that the hydrogen practice mission was conceptualised for conversion of a 10-coach diesel-electric a number of unit (DEMU) right into a hydrogen-powered a number of unit, with two 1600 HP Energy vehicles. With a practice size of 10 coaches, it can have a capability to hold greater than 2,600 passengers.
It has been deliberate to function the hydrogen practice between Jind and Sonepat stations of Northern Railway in Haryana, two round-trips of 356 km. The hydrogen storage and fueling facility at Jind can have a storage capability of three,000 kg of Hydrogen.

How will it work?
Hydrogen gas expertise remains to be an rising discipline in Railways. There are numerous challenges and security considerations, too, as hydrogen is a extremely flammable gasoline. Because the mission entails the retro-fitment of two diesel-powered vehicles into Hydrogen gas cell-powered vehicles, every energy automobile will carry 220 kg of hydrogen, saved in specifically designed cylinders at 350 bar strain. The mounting construction of hydrogen cylinders and gas cells is crucial and for that, a number of rounds of testing are on.
Hydrogen is the lightest factor. It’s colourless, odourless, tasteless, and extremely flammable. Attributable to its typical traits, security stays a degree of warning whereas coping with hydrogen. Officers stated that to minimise the chance, Railways have performed computational fluid dynamics (CFD) research, whereby the worst instances of hydrogen leak and different failure modes are thought-about with steady monitoring.
The official additional stated that an in depth testing of all in-house gear like car management system, increase converter, traction converter, auxiliary converter, and traction motor have been efficiently accomplished. The hydrogen practice will embody security options akin to strain aid valves, leak detection, flame detection sensors, temperature detection programs, and scientifically designed air flow.
An unbiased third-party security auditor – ‘Technischer Überwachungsverein Süd’ (TUV-SUD) of Germany has been roped in for making certain the protection requirements. The engineering design and conversion work is being undertaken at ICF, Chennai by Hyderabad-based Medha Servo Drives.

The hydrogen fuelling facility
The three,000-kg hydrogen fuelling facility at Jind will present the required hydrogen for the operation of the hydrogen-powered practice. The storage capability has been divided into two separate storage areas — 2320 kg at low strain and 680 kg at excessive strain.
The ability will probably be operated and maintained in accordance with the requirements and specification of Petroleum Explosives Security Organisation (PESO), a nodal company below the Division for Promotion of Business and Inner Commerce (DPIIT).
Officers stated that Northern Railway is endeavor the related infrastructure works akin to energy provide, street development, firefighting tank, and so on, to make the power operational.
