Kochi is upgrading its urban transport infrastructure with the introduction of fast electric-hydrogen hybrid ferries connecting Aluva to Cochin International Airport. The initiative aims to reduce travel time to about 10 minutes while minimizing environmental impact, according to a Times of India report.
Currently, Water Metro ferries operate primarily on battery power with diesel backup. To address concerns over battery supply and diesel emissions, authorities are exploring greener alternatives.
“We plan to deploy fast boats on the Aluva–Airport route so commuters can reach the terminal in about 10 minutes,” said Sajan P John, Chief Operating Officer of Kochi Water Metro Ltd (KWML).
The electric-hydrogen vessels emit only water vapour and heat, making them one of the cleanest transport options. Cochin Shipyard Ltd, building the first batch of 23 Water Metro ferries, has already launched India’s first green hydrogen ferry—a 50-passenger, zero-emission vessel operating in Varanasi.
Bharat Petroleum Corporation Ltd has held positive discussions with KWML, and Anert has announced subsidies to support hydrogen ferry deployment.
A hydrology study is underway to assess the feasibility of operating fast vessels along the 8-km Periyar stretch from Aluva to Nedumbassery via the Chengal Canal. “The study will evaluate any impact on water flow and is expected to conclude next month, after which we will submit the report to the state government for approval,” an official said.
The project is designed to reduce road congestion and provide seamless airport connectivity, including a proposed skywalk linking Aluva Metro station with the Water Metro terminal. With hydrogen costs declining and national targets supporting further reductions, KWML sees hydrogen as a long-term solution for sustainable water transport.
