Numaligarh Refinery Limited (NRL) has invited bids for a green hydrogen project at its Numaligarh site in upper Assam, SolarQuarter reported. The tender covers the engineering, procurement and construction of a low-carbon hydrogen facility at the refiner's 3 MMTPA complex in Golaghat district, in the Brahmaputra valley.

What does NRL's tender signal?

The bid invitation marks NRL's first entry into green hydrogen production. The state-run unit processes crude from the Upper Assam oilfields operated by Oil India Limited and ONGC. NRL runs the only public-sector refinery in India's northeast.

The refiner supplies petroleum products across the eight northeast Indian states — Assam, Arunachal Pradesh, Meghalaya, Manipur, Mizoram, Nagaland, Tripura and Sikkim — and exports to Bangladesh and Bhutan.

How does the tender fit India's hydrogen policy?

The tender aligns with India's National Green Hydrogen Mission, which the Union Cabinet approved in January 2023. The mission carries a ₹19,744 crore outlay and a 5 million-tonne annual production target by 2030.

The mission subsidises electrolyser deployment, renewable-power integration, and end-use offtake across refinery, ammonia, methanol and mobility segments through the Strategic Interventions for Green Hydrogen Transition (SIGHT) scheme.

IndianOil, Bharat Petroleum (BPCL) and Hindustan Petroleum (HPCL) — the country's three largest state oil marketing companies — have moved into the segment over the past two years. They have launched captive and merchant green hydrogen projects to decarbonise refinery hydroprocessing and ammonia production. NRL's bid invitation adds the fourth state refiner to the list.

What remains undisclosed?

SolarQuarter's headline did not specify the project's capacity in megawatts, the electrolyser technology stack (alkaline, proton-exchange membrane, or solid-oxide), the renewable-power supply arrangement, or the commissioning timeline.

The trade publication's first word on the tender was the bid call itself. Bid value, scope schedule, and capacity details will come from NRL's tender documents.

What does the bidder scope typically cover?

The typical scope covers electrolyser supply, balance-of-plant engineering, integration with renewable power, hydrogen storage, and compression infrastructure for offtake into the refinery's hydroprocessing block.

NRL's hydroprocessing units currently consume hydrogen produced on-site by steam methane reformers. A green hydrogen unit would offset a portion of that grey hydrogen output.

How does the tender relate to the broader Numaligarh expansion?

NRL sits within a separate, sanctioned capacity expansion programme at Numaligarh. The Numaligarh Refinery Expansion Project (NREP) is under execution, adding a 6 MMTPA crude unit, a petrochemical block and a polypropylene unit to lift throughput to 9 MMTPA.

The green hydrogen tender sits outside the NREP scope. The hydrogen project remains in the appraisal stage, pending the bid process, a separate FID, and award.

What is NRL's ownership structure?

The refiner's majority owner is Oil India Limited, which holds a 69.63% stake. The Government of Assam holds the balance following a 2021 share purchase.

NRL operates under the administrative control of India's Ministry of Petroleum and Natural Gas.

What should the trade watch?

For the trade, the watch items are:

• Bid submission deadline
• Disclosed project capacity in MW
• Electrolyser technology selection
• Renewable-power tie-up structure (captive PPA or third-party wheeling)
• Commissioning target
• Whether the project qualifies for viability gap funding under the SIGHT scheme
• Award date and the contract structure that emerges
