Question 1

What is India's National Water Metro Guidelines, 2026?

Accepted Answer

It's a framework the Ministry of Ports, Shipping and Waterways is formulating to standardize how India plans, builds and safely runs urban water transport — covering a zero/low-emission technical framework for vessels, financing structures, and coordination between the central and state agencies involved. As of the latest Lok Sabha update, the guidelines are still being drafted, not notified.

Question 2

How many hybrid-electric vessels has India deployed so far, and where?

Accepted Answer

Four hybrid-electric catamarans are already in commercial service — in Varanasi, Ayodhya, Patna and Kolkata — built by Hooghly Cochin Shipyard Limited and operated by Inland and Coastal Shipping Limited. Four more are in the pipeline, and IWAI has separately contracted a consortium for 10 additional hybrid-electric ferries.

Question 3

What makes the Varanasi hydrogen fuel-cell vessel different from the hybrid-electric ferries?

Accepted Answer

It runs on a low-temperature PEM hydrogen fuel cell rather than grid-charged batteries alone — a 24-metre catamaran carrying 50 passengers up to 8 hours per hydrogen fill, combining the fuel cell with batteries and rooftop solar. It's India's first indigenous hydrogen fuel-cell passenger vessel, built by Cochin Shipyard.

Question 4

Which cities are part of India's planned water metro rollout?

Accepted Answer

IWAI has completed feasibility studies for 15 of 18 identified locations. Reported Phase I cities include Guwahati, Srinagar, Patna, Varanasi, Ayodhya and Prayagraj, with Tezpur and Dibrugarh proposed for Phase II.

Question 5

Has the National Water Metro program been approved yet?

Accepted Answer

Not fully. The guidelines governing the program are still being formulated, and while 15 of 18 feasibility studies are complete, that's a planning milestone rather than a funded, approved rollout in every city. The hybrid-electric and hydrogen vessels already in service run under separate, earlier ministry initiatives.

Question 6

How does the Kochi Water Metro relate to this national rollout?

Accepted Answer

Kochi is the working proof of concept. Built by the same Cochin Shipyard using the same hybrid-electric ferry model, it has carried more than 40 lakh passengers since 2023 and is described as the world's largest electric-boat metro system — the template the national guidelines and 18-city feasibility pipeline are now trying to scale.
