On December 11, 2025, Union Minister for Ports, Shipping and Waterways Sarbananda Sonowal flagged off India's first fully indigenous hydrogen fuel cell-powered passenger vessel from Namo Ghat in Varanasi, marking a landmark milestone in India's green maritime sector. The vessel was developed by Cochin Shipyard Limited (CSL) and is operated by the Inland Waterways Authority of India (IWAI) on National Waterway-1 (NW-1), the Ganga river. Key technical specifications: the vessel carries 50 passengers with full air-conditioning, uses Low-Temperature PEM (Proton Exchange Membrane) fuel cell technology, can operate for approximately 8 hours on a single hydrogen refill, and emits only water — making navigation on the Ganga completely pollution-free. The vessel marks India's entry into zero-emission inland water transport, aligning with the National Green Hydrogen Mission (launched January 2023, target: 5 MMT green hydrogen production by 2030), and the broader Harit Nauka initiative to decarbonise India's inland waterways. IWAI manages over 111 national waterways across India under the National Waterways Act, 2016. The Ganga, designated as NW-1, is the longest national waterway at 1,620 km (Allahabad-Haldia). This development is significant for Rajasthan context as it demonstrates India's commitment to renewable energy and indigenous manufacturing under the Aatmanirbhar Bharat framework — the National Green Hydrogen Mission also envisions hydrogen as a future fuel for Rajasthan's energy transition given the state's abundant solar potential.
