Major ports in India have undertaken initiatives under the Green Tug Transition Programme (GTTP) and the Harit Sagar Green Port Guidelines to reduce carbon intensity. Measures include transition from diesel powered tugs to electric and hybrid tugs, adoption of renewable energy and electrification of port equipment, vehicles and railway tracks, deployment of zero emission trucks and onshore power supply systems. Four major ports, Deendayal Port, Jawaharlal Nehru Port, Visakhapatnam Port and V.O. Chidambaranar Port, have placed work orders for electric tugs. The Ministry of New and Renewable Energy has recognised Deendayal Port Authority in Gujarat, Paradip Port Authority in Odisha and V.O. Chidambaranar Port Authority in Tamil Nadu as Green Hydrogen Hubs under the National Green Hydrogen Mission. All ports are providing shore to ship power facilities to smaller crafts. Incentives amounting to Rs 533.9 mn have been provided to 109 ship recycling yards through the Ferrous Scrap Development Fund up to 2026. Deendayal Port has commissioned a one megawatt (MW) electrolyser based green hydrogen plant and has obtained a Port Readiness Level of six, progressing to seven, for Kandla Port for bio methanol bunkering operations. The port has allotted 3,400 acres to developers for Green Hydrogen and Green Ammonia projects and has developed a jetty with capacity of three point five million (mn) tonne (t) per annum compatible with handling green ammonia. These assets aim to attract private investment for fuel and bunker supply chains. V.O. Chidambaranar Port has allotted 205.72 acres for Green Hydrogen and Green Ammonia projects, commissioned a 10 Nm3 capacity pilot green hydrogen plant in April 2025 and is developing a green methanol bunkering facility with two 750 cubic metre tanks. The government has approved development of a Green Hydrogen and Green Ammonia handling jetty at Paradip Port through a public private partnership with an estimated cost of Rs 7.9717 billion (bn) and a cargo handling capacity of four million (mn) tonne (t) per annum. The Union Minister of Ports, Shipping and Waterways provided these details in a written reply to the Lok Sabha.
