Green corridors: Reimagining India’s ports as engines of the energy transition

Ports are uniquely positioned to anchor India’s green transition for three reasons. First, they are major energy consumers and thus offer large and immediate abatement potential through electrification and renewable integration. Second, ports are natural aggregation points for clean fuels such as green hydrogen, ammonia, methanol, liquefied natural gas and biofuels, enabling scale in production, storage, bunkering and exports. Third, ports act as interfaces between global shipping and domestic policy.

This strategic logic has translated into clear national intent. India’s road map envisages the development of carbon-neutral major ports, widespread adoption of shore-to-ship power, more than 90 per cent electrification of port equipment, and a sharp increase in the share of renewable energy to over 60 per cent by 2030 and over 90 per cent by 2047.

Indian ports have already made progress in deploying rooftop and ground-mounted solar power, with several major ports achieving renewable shares well above national averages. This momentum is now being reinforced through hybrid renewable systems, green power purchase agreements and energy storage solutions. Electrification of cargo handling equipment and intra-port vehicles is advancing steadily, supported by affordable battery costs and improved operating economics. Rubber-tyred gantry cranes, yard tractors, forklifts and buses are progressively moving away from diesel.

In parallel, onshore power supply (OPS) is emerging as a critical enabler of emissions reduction at berth. With regulatory push and clear timelines for port-stationed, coastal and eventually export-import vessels, OPS is no longer an optional green feature but an essential component of future-ready port infrastructure.

India’s ambition to develop multiple green hydrogen and green ammonia hubs at major ports reflects a recognition that ports can anchor industrial-scale decarbonisation while supporting exports to global markets. Ports such as Deendayal, V.O. Chidambaram and Paradip are already at different stages of developing hydrogen production, bunkering, storage and allied infrastructure. Ports are preparing for green methanol and biomethanol bunkering, recognising their near-term potential for maritime decarbonisation.

India’s green port agenda is extending beyond port gates into shipping lanes. The development of international and domestic green shipping corridors, including links with Singapore and Europe, signals a move from isolated port-level action to coordinated value chain decarbonisation. Supporting this transition is the Green Tug Transition Programme, which aims to progressively replace conventional harbour tugs with hybrid, electric and alternative fuel variants.

The scale of transformation required is substantial. Investments are needed across shore power systems, renewable generation, electrification, hydrogen and green fuel hubs, pollution control, digital monitoring and climate-resilient infrastructure. Indicative requirements range from Rs 50 million-Rs 70 million per MW for renewable energy to Rs 1 billion-Rs 10 billion for electrification and emission reduction, and Rs 5 billion-Rs 50 billion or more for integrated green fuel hubs at large ports. Green finance instruments, blended finance structures and viability gap support will be critical to accelerating deployment, particularly for first‑of‑a‑kind projects.

The next phase of India’s green port journey will require moving beyond project-level interventions to systems thinking. This means aligning port master plans, energy planning, fuel supply chains, shipping strategies, digital platforms and skill development within a unified sustainability framework. Equally important is collaboration between ports, shipping lines, energy developers, technology providers, regulators and global partners.
