Green methanol can make Indian ports hubs of maritime decarbonisation. Discuss the opportunities and challenges.

Green (e-)methanol — methanol synthesised from renewable hydrogen and biogenic CO2 — is emerging as the leading drop-in fuel for decarbonising shipping. India's first port-based e-methanol plant at Deendayal Port, Kandla (150 TPD, over ₹1,200 crore) [1] marks a shift of ports from cargo gateways to green-fuel hubs, though the transition remains demand- and infrastructure-constrained.

Opportunities

• Locational advantage: Kandla sits astride the Asia–Europe Singapore–Rotterdam corridor, allowing India to move from bunker-fuel importer to green-fuel exporter [1].
• An ecosystem already forming: MNRE has recognised Deendayal, Paradip and V.O. Chidambaranar ports as Green Hydrogen Hubs [3], while the proposed Kandla–Tuticorin Coastal Green Shipping Corridor offers assured domestic demand independent of global rules [2].
• Economic spillovers: over 3,500 direct and indirect jobs [1], plus a value chain in electrolysers, storage, bunkering and ship repair.
• Climate and self-reliance: renewable hydrogen with biogenic CO2 cuts fossil bunker imports and serves Net Zero 2070, backed by the National Green Hydrogen Mission's ₹19,744 crore outlay [4].

Challenges

• Demand is rule-dependent: the IMO Net-Zero Framework (a marine fuel standard plus emission pricing under MARPOL) was deferred by twelve months at the MEPC session in October 2025 [5]. Plants may be commissioned before the rule that makes their fuel saleable exists.
• Feedstock gap: Kandla's green hydrogen facility is 1 MW pilot scale [6] — far short of what 150 TPD requires; no biogenic CO2 supplier has been tied down.
• Delivery infrastructure lags production: bunkering is a separate project, as VOC Port's 750 m³ green methanol facility shows [2]. Without port-side terminals, fuel must be trucked, eroding cost competitiveness.
• Offtake risk: green methanol remains costlier than fuel oil, and long-term purchase agreements with shipping lines are absent.

Green methanol's promise is real but conditional: production capacity alone does not create a market. Binding offtake contracts, electrolyser capacity sized to demand, bunkering built on the same timeline as plants, and active Indian advocacy at the IMO can convert first-mover risk into first-mover advantage — anchoring ports as engines of the Net Zero 2070 pledge.
