The Ministry of New and Renewable Energy (MNRE) recognised three major ports as Green Hydrogen Hubs under the National Green Hydrogen Mission (NGHM): Deendayal Port Authority (Gujarat), V.O. Chidambaranar Port Authority (Tamil Nadu), and Paradip Port Authority (Odisha). These ports will serve as integrated centres for production, consumption, and export of green hydrogen.

V.O. Chidambaranar Port commissioned a ₹25 crore pilot project with 10 Nm3/hr capacity for applications like street lighting and EV charging. Deendayal Port commissioned a megawatt-scale indigenous facility (₹13 crore) with 140 metric tonnes annual capacity. Green Hydrogen Hubs aim to reduce emissions in hard-to-abate sectors like steel, cement, and shipping.
