Q. Discuss the significance of hydrogen fuel cell technology in decarbonizing India's transport sector, with reference to the recently approved hydrogen trainset on the Jind-Sonipat section. (15 marks, 250 words)

Transport contributes a significant share of India's fossil-fuel emissions, and hard-to-electrify routes keep diesel entrenched. Hydrogen fuel cells—which generate electricity by combining hydrogen and oxygen, emitting only water vapour—offer a zero-carbon pathway. The recently approved 10-car trainset on the Jind–Sonipat section (Northern Railway) marks India's first indigenous rail application, anchoring this transition [1].

Environmental significance - Zero direct CO₂; sole emission is water vapour, aiding India's net-zero-2070 and Panchamrit pledges [1]. - Displaces diesel on non-electrified and heritage routes where overhead electrification is uneconomic.

Energy security & economic significance - Green hydrogen for the train is produced via electrolysis at an indigenous Jind plant, cutting import dependence [1]. - Aligns with the National Green Hydrogen Mission (₹19,744 crore), targeting ~₹1 lakh crore fossil-fuel import savings and ~50 MMT/annum CO₂ cuts by 2030 [2].

Technological & strategic significance - First 2400 kW (2×1200 kW) fuel-cell trainset (75 kmph) showcases indigenisation, following the KPIT-CSIR hydrogen bus and Varanasi vessel [1]. - Under "Hydrogen for Heritage," Railways plans 35 hydrogen trains, positioning India as a green-technology exporter [1][2].

Challenges persist—high electrolyser and storage costs, refuelling infrastructure, and safety—warranting a calibrated, pilot-first scale-up. Nonetheless, the Jind–Sonipat trainset demonstrates that fuel-cell mobility can decarbonize transport while building an indigenous value chain. Scaled under NGHM with SIGHT incentives, it advances India's twin goals of clean mobility and SDG-7 (affordable clean energy).
