Indian Railways is making significant strides towards sustainability and reducing carbon emissions by introducing hydrogen trains as part of its initiatives to combat climate change. The 'National Hydrogen Mission' spearheaded by Prime Minister Narendra Modi's government aims to align with the goals of the Paris Climate Agreement. Recently, Himachal Pradesh's Chief Minister urged the Ministry of Railways to consider running trains on green hydrogen along the iconic Kalka-Shimla railway, a UNESCO World Heritage site. The state's commitment to becoming a green energy hub by 2026 has led to various strategies, including utilizing hydrogen fuel cell-based trains. The first hydrogen train in India is set to launch in the fiscal year 2024-25, with trial runs starting on the Northern Railway's Delhi Division by the end of the current year. Indian Railways plans to introduce 35 hydrogen trains on heritage and hill routes, emphasizing the shift towards cleaner transportation. Significant investments have been allocated for the development of hydrogen trains and infrastructure, marking a pivotal step towards sustainable and eco-friendly railway operations.
