Union Minister for Ports, Shipping and Waterways Sarbananda Sonowal flagged off India's first indigenous hydrogen fuel cell passenger vessel at Namo Ghat in Varanasi on December 11, 2025. Developed by Cochin Shipyard Limited (CSL), the vessel uses Low-Temperature PEM fuel cell technology, enabling silent, vibration-free cruising with zero emissions — only water as a byproduct. The vessel carries 50 passengers with full air-conditioning and can operate for approximately 8 hours on a single hydrogen refill. The maiden commercial run covered a 5-km trip from Namo Ghat to Lalita Ghat. The vessel is expected to boost local tourism and position Varanasi as one of the world's first cities to adopt hydrogen-powered passenger transport on inland waterways (National Waterway 1 — the Ganga).
