India's hydrogen decade now runs through ten truck routes

Nitin Gadkari and Pralhad Joshi, two of India's most senior ministers, flagged off sixteen hydrogen trucks in March 2025, with Tata Motors' executive director Girish Wagh beside them. Some of the trucks burn hydrogen in a modified combustion engine; others run it through a fuel cell. Over the following twenty-four months they will haul freight on routes around Mumbai, Pune, Delhi-NCR, Surat and Vadodara, and into the steel towns of Jamshedpur and Kalinganagar, carrying 300 to 500 kilometres of range and the Ministry of New and Renewable Energy's money. Sixteen trucks is a small fleet. The programme riding on them is not.

The programme is the National Green Hydrogen Mission, approved by India's cabinet in January 2023 with an outlay of $2.1 billion (₹19,744 crore), and it is about to meet its first hard date. Scheduled commercial dates for the mission's first tranche of subsidised production plants begin in August 2026. Until now, progress has mostly been measured in awards and announcements; from August, the measure becomes commissioned plants.

01A mission sized like an industrial policy

The cabinet decision of 4 January 2023 set out the shape of the bet. Of the outlay, $1.83 billion (₹17,490 crore) funds SIGHT, the incentive programme that pays green hydrogen producers and electrolyser manufacturers; $154 million (₹1,466 crore) funds pilot projects, including the trucks; $42 million (₹400 crore) goes to research. The targets attached to that money explain the attention the mission gets: five million tonnes of green hydrogen a year by 2030, about 125 GW of renewable generating capacity to power it, nearly $84 billion (₹8 lakh crore) of expected investment and six lakh jobs. The government expects the target, if met, to avert nearly 50 million tonnes of CO2 emissions a year and displace $10.5 billion (₹1 lakh crore) of fossil-fuel imports annually. [1] Dollar figures here and throughout are converted at ₹95.36 to the dollar, the rate in early July 2026.

Almost all the hydrogen India uses today is grey, made from natural gas and consumed by refineries and fertiliser plants. Green hydrogen replaces the gas with renewable electricity and an electrolyser. The mission's premise is that India's cheap solar power can make it one of the world's low-cost producers, supplying its own industry first and export markets after. The scale of that premise is worth sitting with: producing five million tonnes a year would need roughly 250 to 275 TWh of renewable electricity annually, on the order of 100 to 120 GW of dedicated solar capacity. [2]

SIGHT, the mission's financial engine, works through two windows. One pays manufacturers an incentive for every megawatt of electrolyser capacity built in India. The other pays producers a per-kilogramme subsidy on green hydrogen for their first years of operation, awarded through competitive auctions run by the Solar Energy Corporation of India. Winning an auction fixes both the subsidy and a scheduled commercial date. The tranche dates are contractual commitments, in other words, which is what makes August 2026 the mission's first genuine test rather than another announcement.

02What the next four years must carry

The mission's own numbers describe the distance left. As of February 2026, India had commissioned about 8,000 tonnes a year of green hydrogen capacity, 0.16 per cent of the 2030 target, a gap laid out by the policy consultant Sagari Gupta in a Business Today column this June. [3] Awards run far ahead of construction: by May 2025, nineteen companies held SIGHT production allocations totalling 862,000 tonnes a year, and fifteen firms held manufacturing incentives for 3,000 MW of annual electrolyser capacity. [4] An allocation is a subsidy contract, not a plant; August is when the first of those contracts fall due.

Worked through, the arithmetic is stark. Reaching five million tonnes by the end of 2030 from today's base requires commissioning just over a million tonnes of new capacity a year, every year. The mission's first three years produced 8,000 tonnes in total, so the required pace is roughly 390 times the historical one. That is arithmetic rather than a forecast: capacity arrives in lumps, and the 862,000 tonnes already under award are designed to land in waves from August onwards. What the sum does measure is how much of the mission's credibility now rests on the tranche dates holding.

Gupta's column is one of several recent reality checks from within India's policy community, and she is not arguing that the mission has failed. Most awarded plants remain inside their scheduled build windows, and the auction machinery demonstrably works. The concern is sequencing: subsidised supply is being built ahead of any committed demand, and the demand side of the mission is exactly where the trucks come in.

The quieter half of the bet deserves a line here too. The 3,000 MW of electrolyser manufacturing incentives spread across fifteen firms is a hedge on the production timetable: even where plants slip, a domestic electrolyser industry lowers the capital cost of every project that follows, whether or not any given plant meets its date.

03Ten routes, thirty-seven vehicles

The transport leg was sanctioned in March 2025: five pilot projects putting 37 hydrogen vehicles on ten routes, supported by nine refuelling stations and $22 million (₹208 crore) of central funding. Fifteen of the vehicles run fuel cells; twenty-two run hydrogen internal-combustion engines. [5] The routes are working corridors rather than showcases — Greater Noida–Delhi–Agra, Ahmedabad–Vadodara–Surat and Bhubaneshwar–Konark–Puri among them — and the awardees span the industry: Tata Motors, Ashok Leyland, Reliance Industries, NTPC and the state-owned oil marketers. The vehicles are expected on the road within eighteen to twenty-four months of sanction.

The trials that began in March 2025 show what those corridors look like in practice. Tata Motors' programme runs sixteen trucks across both architectures, with operating ranges of 300 to 500 kilometres, on freight routes that include the steel corridors into Jamshedpur and Kalinganagar. Heavy, regular, depot-to-depot freight is the duty cycle where a single refuelling station can serve an entire rotation, which is why the pilot design favours it: nine stations are enough to keep ten fixed routes fuelled, and not much more than that.

Set against the mission's full map, though, trucking is a small line, and the title of this essay needs defending. The mission's own component list spreads pilot money across three demand sectors: $52 million (₹496 crore) for mobility, $48 million (₹455 crore) for low-carbon steel and $12 million (₹115 crore) for shipping. [6] The bulk of early demand is expected where hydrogen is already consumed — the refineries and fertiliser plants that buy grey today — and the mission holds powers to mandate consumption by designated consumers. Mobility nonetheless carries the largest of the three pilot allocations, and it is the only sector where the fuel, the vehicle and the refuelling economics are being tested in public at once. Volume will come from industry, if it comes at all; the routes' job is proof.

The ministry does not treat the pilots as an end state. Business Standard reported in June 2025 that the government wants at least a thousand hydrogen trucks and buses running by 2030. [7] And at a SIAM eco-energy symposium this February, the mission's director confirmed the next batch.

In the Hydrogen Mission, we have already sanctioned 37 vehicles and 10 fuelling stations. We are also going to sanction another 30 vehicles, again buses and trucks.

Abhay Bakre, Mission Director, National Green Hydrogen Mission — SIAM symposium, February 2026

Bakre also told the symposium why trucking, of all hydrogen's possible customers, gets the pilot money: mobility, he said, is one area where green fuels "can be experimented with and then scaled up in a much more effective and equitable manner than most other sectors". [8] The logic holds up. A refinery converts to green hydrogen only with years of committed supply behind the decision; a fleet needs a route, a station and a reason to switch. The pilots exist to establish all three at small scale before anyone is asked to commit at large scale.

04The combustion tilt

One detail of the pilot design deserves a pause: the split. Twenty-two of the 37 vehicles burn hydrogen in a combustion engine rather than converting it in a fuel cell. A hydrogen engine is, in essence, a modified diesel engine: cheaper to build, tolerant of less-pure fuel, and serviceable by the mechanics who already keep India's trucks running. A fuel cell turns more of each kilogramme of hydrogen into motion but costs considerably more up front. India's pilot fleet leans towards the engine.

That tilt has company. Daimler Truck signed with the Munich engine developer KEYOU in June 2026 to bring hydrogen-combustion trucks to market by 2027, weeks after previewing its NextGenH2 hydrogen truck beside the battery-electric eActros range at IAA 2026. Volvo Group showed a hydrogen combustion truck using high-pressure direct injection this April. MAHLE's powertrain arm converted a 13-litre heavy-duty diesel to run on hydrogen and reported diesel-level torque from it. FAW Jiefang, one of China's oldest truck makers, unveiled its first hydrogen engine at a new engine plant in May. None of these companies has abandoned the fuel cell; each is hedging the same cost-and-serviceability question that India's 22-to-15 split encodes. For India's component industry, which lives on diesel drivelines, the answer carries real money: a hydrogen engine keeps blocks, cranks, injectors and the service network in work, where a fuel-cell transition would retire much of that base.

The fuel-cell side has its own evidence, and it is substantial. Hyundai's XCIENT fleet of 165 fuel-cell trucks, working in Switzerland, Germany, France, the Netherlands and Austria, passed 20 million cumulative kilometres in February, five years after the first units entered service. Hyundai's commercial-vehicle chief Chul Youn Park said in the February announcement that the trucks "continue to demonstrate their value as mobility solutions for a more advanced future". Toyota and Isuzu, meanwhile, agreed in April to build Japan's first mass-produced fuel-cell truck. Twenty million kilometres is the deepest durability record hydrogen trucking has anywhere; it was also earned under Swiss subsidy structures and European energy prices, which travel poorly.

What India's pilots add to all this is a controlled comparison. One mission is paying for both architectures to haul real freight on the same corridors, refuelled from the same stations, over the same eighteen-to-twenty-four-month window. Nowhere in Europe or China is the engine-versus-fuel-cell question being run this directly. The readouts, due through 2027, will say more about the choice than any spec sheet published so far.

05The price everything waits on

Neither architecture survives the wrong fuel price. Government-negotiated procurement of green hydrogen for Indian refineries currently lands at $4.06–4.16 per kilogramme (₹387–397, including 18 per cent GST), Gupta reported, adding that "the current floor for green hydrogen remains well above what unsubsidised grey hydrogen procurement has historically cost Indian refiners". [3] For trucking, RMI's India analysts put the parity threshold at $3.15–4.19 per kilogramme (₹300–400), approximately half the price they project from current projects. [9] The negotiated refinery price and the trucking parity band are close enough to be interesting, and far enough apart to decide investment cases.

The rest of RMI's cost stack points beyond the molecule itself. Production accounts for only around 40 per cent of the final price of dispensed hydrogen in their breakdown; compression, storage, transport and the station carry the rest, which is why cheap electrons alone do not deliver cheap fuel at a nozzle. A refuelling station dispensing 400 kilogrammes a day costs about $2.2 million (₹21 crore) to build at 2025 prices, and hydrogen carries 18 per cent GST, a rate the analysts argue should fall to 5 per cent. Their modelling, run across duty cycles from 150 to 700 kilometres a day and truck weights of 18 and 55 tonnes, has fuel-cell trucks becoming cheaper to own than diesel by 2040 on current trajectories. [9] A payback date fourteen years out is not a purchase argument; it is a description of how much work the fuel price still has to do.

There is one place the auction machinery has already moved prices: derivatives. SECI's green ammonia awards under the SIGHT programme came in at $0.52–0.68 per kilogramme (₹49.75–64.74) against a global benchmark around $1.15 (₹110), with 724,000 tonnes a year allocated across thirteen fertiliser units. [2] Ammonia is not truck fuel. The prices still matter to trucking, because they show what committed, aggregated demand does to costs in this market — and committed, aggregated demand is precisely what no truck fleet has yet offered.

06Ports before pumps

India's first hydrogen demand at scale may not be domestic at all. The shipping ministry has designated three ports — Kandla in Gujarat, Paradip in Odisha and Tuticorin in Tamil Nadu — as export hubs for green hydrogen, ammonia and methanol. Tuticorin has set aside 500 acres for a hydrogen hub, Kandla has invited expressions of interest from developers, and Odisha is allocating land near Paradip to producers. [10] The logic is the same one that shaped the SECI ammonia awards: a port can bundle production, storage and shipping into a single project that a lender can underwrite, and the buyers on the other end, fertiliser importers and shipping lines decarbonising under their own mandates, already exist at scale.

The receiving end is under construction too. In May this year, Daimler Truck, MB Energy and Kawasaki Heavy Industries agreed to develop a liquefied-hydrogen supply chain into Europe through the port of Hamburg. An exporter with port land and a derivative product can sign the long offtake contracts that project financiers require before lending; a domestic truck route cannot, yet. If India's first large plants end up financed against export contracts, the price a Pune fleet pays at the pump will be shaped by ammonia buyers several time zones away.
