Water, split apart by electricity, becomes the fuel of the future, that’s the almost embarrassingly simple idea sitting at the center of one of India’s most ambitious industrial bets. The government isn’t just hoping this works. It’s backing it with ₹19,744 crore and a target that would make India one of the largest green hydrogen producers on Earth. Whether that target is realistic is a different question entirely, and it’s worth answering honestly.

What Green Hydrogen Actually Is
Green hydrogen production comes down to one process: electrolysis, where electricity splits water into hydrogen and oxygen inside a machine called an electrolyzer. The “green” part matters enormously – hydrogen only earns that label if the electricity powering the split comes from renewable sources like solar or wind, not from natural gas or coal. [Source]
Three electrolyzer types currently compete for dominance. Alkaline electrolyzers are the cheaper, more established choice. PEM electrolyzers run at lower temperatures with faster response times, useful for pairing with variable renewable power. Solid oxide electrolyzers operate at scorching temperatures above 700°C but promise higher theoretical efficiency. None has won outright yet, and which technology eventually dominates will shape how competitive India’s green hydrogen production actually becomes.
India’s National Green Hydrogen Mission
The National Green Hydrogen Mission, approved by the Union Cabinet in January 2023, set a genuinely audacious target: 5 million metric tonnes of annual green hydrogen production by 2030, potentially climbing to 10 MMT if export demand cooperates. [Source] Getting there requires an additional 125 GW of dedicated renewable capacity, roughly equivalent to India’s entire wind and hydro sectors combined today.
Most of the mission’s ₹19,744 crore budget, about ₹17,490 crore, flows through the SIGHT programme, which incentivizes both electrolyzer manufacturing and actual hydrogen production. Smaller allocations cover pilot projects in steel, mobility, and shipping, alongside research and development. By 2030, the government projects this could unlock over ₹8 lakh crore in total investment, create 600,000 jobs, and cut fossil fuel imports by more than ₹1 lakh crore annually. These are the kind of numbers that make headlines. Whether they survive contact with reality is the harder question.
The Global Race: Where India Really Stands
Here’s the part that rarely makes it into celebratory coverage: India ranks second globally in green hydrogen production capacity, but second place isn’t as close to first as it sounds. China’s capacity reached 1.2 million tonnes in 2025, nearly half of total global capacity, while India sat at just 0.5 MMT. [Source] India needs to roughly tenfold its current output in under five years to hit its 2030 target.
The global picture adds another layer of caution. Only 8 million tonnes of green and blue hydrogen capacity was actually operational or under construction worldwide by the end of 2025 – just 24% of what project pipelines had announced for 2030. The International Energy Agency expects only 4-6 million of the 37 million tonnes announced globally will actually materialize. This gap between announcement and delivery isn’t unique to India; it’s the defining risk shadowing every country’s hydrogen ambitions. Understanding that context matters before taking any single country’s targets at face value.
The Cost Problem Nobody Can Wish Away
Cost is where India’s hydrogen ambitions meet their hardest test. As of 2026, green hydrogen production in India costs between ₹397-560 per kg, compared to grey hydrogen’s ₹150-200 per kg meaning the clean alternative remains two to three times more expensive than what it’s meant to replace. The lowest price discovered through competitive bidding, for supply to Indian Oil’s refineries, came in at ₹397 per kg including GST. Genuine progress, but still far from parity.
Renewable energy costs drive 50-70% of total production expenses, with electrolyzer capital costs forming the next largest chunk. The consensus among analysts is sobering rather than optimistic: reaching the widely cited USD 2/kg threshold for unsubsidized cost competitiveness is unlikely before 2030, and may not arrive until 2032-2035 for most projects. Even in India’s most favorable states, unsubsidized prices currently hover around USD 4.4-4.8/kg. Subsidies help, bringing effective prices closer to USD 3/kg, but that’s still roughly 50% above where mass-market viability is thought to begin.
Who’s Actually Building This
India’s electrolyzer manufacturing base has scaled quickly through government-backed PLI tenders, which allocated 1.5-2.22 GW of annual manufacturing capacity across eight to nine companies. Reliance Electrolyser Manufacturing secured 300 MW using licensed alkaline technology and has stated ambitions toward 100 GW of overall energy production. Adani New Industries received a similar allocation and has broader plans for a 5 GW/year facility at Mundra. L&T Electrolysers commissioned its first plant in Gujarat using licensed alkaline technology, while Ohmium Operations has taken the PEM route, with 400 MW already operational.
On actual hydrogen production rather than equipment manufacturing, Reliance Green Hydrogen and Green Chemicals has secured the largest single disclosed allocation on the official mission portal – 139,000 MT/annum. Adani’s flagship project, the Mundra Green Hydrogen Hub, targets a massive 2.1 MMTPA of hydrogen or its derivatives, built around a fully integrated in-house supply chain spanning solar modules, wind turbines, and electrolysers. Beyond these two conglomerates, independent players including Hygenco, ACME, and ReNew are quietly advancing commercial-stage projects, suggesting the competitive field is broader than the Reliance-versus-Adani framing that dominates headlines.
What This Actually Means Going Forward
India’s green hydrogen story right now is genuinely two stories at once: extraordinary policy ambition paired with a cost and scale gap that won’t close on optimism alone. The global market is projected to grow from roughly USD 12 billion in 2025 to over USD 190 billion by the mid-2030s – a real opportunity if India can close that gap in time. Getting there will demand cheaper renewable electricity, faster electrolyzer cost reductions, and perhaps most importantly – an honest accounting of how far behind schedule the sector currently runs, rather than pretending the 2030 target is already within easy reach.
For readers tracking how this fits into India’s broader clean energy buildout, our earlier piece on renewable energy in India’s current status and future potential covers the grid and generation side that green hydrogen production ultimately depends on.
