A September 2024 project registry compiled by the Indo-German Green Hydrogen Task Force names 126 production projects, 21 electrolyser/fuel-cell manufacturing plants, and 40 other related projects across India. Almost none of it is built yet — but the geography of where it's being announced is itself the story.
The state cluster map
The registry names a project's state for 116 of its 126 production entries (the rest are unlocated multi-site "plans"). Ranked by project count, the picture is a handful of coastal and port-adjacent states doing almost all of the early running:
| Rank | State/UT | Projects | Notable named capacity |
|---|---|---|---|
| 1 | Gujarat | 16 | Essar Jamnagar 1,000 MW; Torrent Dahej 352 MW; GIPCL 15 MW |
| 2 | Odisha | 14 | ACME–IHI Gopalpur 2,000 MW; ACME Kujanga 1,280 MW; ReNew Malkangiri 704 MW |
| 3 | Karnataka | 13 (8 in Mangaluru) | ABC Cleantech 1,275 MW; JSW 26.8 MW |
| 4 | Andhra Pradesh | 10 | NTPC Pudimadaka 3,856 MW; ONGC–Greenko 1,300 MW; Greenko Kakinada 1,300 MW |
| 5 | Maharashtra | 8 | BPCL Ahmednagar 5 MW; Mahagenco Bhusawal |
| 6 | Madhya Pradesh | 7 | ReNew MP 352 MW; BPCL Bina 20 MW |
| 6 | Rajasthan | 7 | Avaada Kota 1,268 MW; ACME Bikaner 6.4 MW |
| 6 | Tamil Nadu | 7 | ACME Thoothukudi 1,500 MW — the pipeline's largest commissioned project |
| 9 | Uttar Pradesh | 6 | IOCL Mathura 32 MW; NTPC Greater Noida (x2) |
| 9 | Kerala | 6 | ReNew Vizhinjam 2,000 MW; IH2A Kochi 150 MW |
| 11+ | Ladakh, Himachal Pradesh, Haryana, Assam, Uttarakhand, Telangana, West Bengal, Jharkhand | 1–5 each | Mostly sub-1 MW pilot/demonstration scale |
Roughly a third of the registry's 126 rows carry no capacity or tonnage figure at all, so these are project-count rankings, not true installed or planned capacity totals — the real gap between announced states is almost certainly wider than this table shows.
Mangaluru, Karnataka: the tightest cluster in the country
No other Indian city hosts as many named green-hydrogen or green-ammonia projects in one place as Mangaluru: ACME, ReNew, Avaada Energy, Petronas, JSW, and O2Power all have projects sited there, alongside Mangalore Refinery and Petrochemicals' own 3.5 MW refinery-hydrogen unit. Most are ammonia-export plays rather than domestic-blending projects — a coastal port city with existing refinery and export infrastructure functioning as a natural staging ground for shipping green ammonia out rather than consuming hydrogen locally.
Odisha's approval rounds — a bigger, messier picture than one headline number
Odisha's state government approved green hydrogen and derivative projects in at least two separate, overlapping tranches reported months apart: one widely cited round of 9 projects worth ₹1,53,000 crore (covering, among others, ACME's Kujanga/Jagatsinghpur ammonia project), and a second, distinct round of 12 projects worth ₹84,918 crore reported separately (covering ReNew's Malkangiri methanol project and REFPL's Rayagada methanol project). The registry's source citations for these rows don't fully reconcile which project belongs to which approval batch — a reminder that state government "project approved" announcements in this sector often stack on top of each other rather than replacing one another, and a single "₹1,53,000 crore" headline number undercounts the state's actual pipeline. Note the arithmetic doesn't close cleanly against the state-rankings table above: 9 + 12 = 21 projects across these two rounds, against the 14 shown for Odisha in that table — almost certainly reflecting overlap between the two announcement rounds (the same project re-announced or re-counted across tranches) rather than 21 genuinely distinct projects, but the underlying sources don't let this article resolve exactly which of the 21 line items are duplicates.
The company map: who's placing bets in more than one state
| Company | States with named projects |
|---|---|
| NTPC | 7+ (Madhya Pradesh, Andhra Pradesh, Uttar Pradesh, Gujarat, Ladakh, Telangana, Rajasthan) |
| IH2A (consortium) | 5 (Kerala, Karnataka, Gujarat, Maharashtra, Andhra Pradesh) |
| ReNew | 4 (Madhya Pradesh, Karnataka, Odisha, Kerala) |
| ACME | 4 (Rajasthan, Tamil Nadu, Karnataka, Odisha) |
| Avaada Energy | 4 (Rajasthan, Karnataka, Madhya Pradesh, Odisha) |
| IOCL | 4 (Haryana, Uttar Pradesh, Kerala, Rajasthan) |
NTPC's spread is the most striking — a state-owned power generator hedging across nearly every major industrial cluster rather than concentrating like private developers such as ACME or Avaada, whose site choices track port access and export logistics more tightly.
Announced isn't built: the top of the pipeline by capacity
| Company | Location | MW | Tonnes/yr | Status |
|---|---|---|---|---|
| NTPC | Pudimadaka, Andhra Pradesh | 3,856 | 547,500 | Announced |
| Greenko | Unspecified | 3,440 | 540,000 | Announced |
| ACME–IHI JV | Gopalpur, Odisha | 2,000 | 229,600 | Announced |
| ReNew | Vizhinjam, Kerala | 2,000 | 220,000 | Announced |
| ACME | Thoothukudi, Tamil Nadu | 1,500 | 213,000 | Commissioned |
| ONGC–Greenko JV | Andhra Pradesh | 1,300 | 184,600 | Announced |
| Greenko ZeroC | Kakinada, Andhra Pradesh | 1,300 | 176,000 | Announced |
| ABC Cleantech | Mangaluru, Karnataka | 1,275 | 200,000 | Announced |
| Avaada Energy | Kota, Rajasthan | 1,268 | 180,000 | Announced |
| Essar | Jamnagar, Gujarat | 1,000 | 142,000 | Announced |
Of the ten largest named projects in the registry, only one — ACME's Thoothukudi plant in Tamil Nadu — was marked commissioned as of September 2024. Every other top-10 project remains at the announcement or pre-construction stage. That pattern matches the national numbers: 8,000 tonnes/year actually commissioned against a 5-million-tonne 2030 target, even as the SIGHT (Strategic Interventions for Green Hydrogen Transition) scheme has signed manufacturing-capacity agreements with 15 electrolyser companies (3,000 MW of manufacturing capacity, backed by ₹4,440 crore of incentives) and production agreements with 18 companies for a combined 862,000 tonnes/year — agreements, again, not yet delivered tonnage. Mission funding itself has ramped slowly: ₹100 crore in FY24, ₹300 crore in FY25, ₹300 crore in FY26 (revised estimate, against ₹600 crore budgeted), and ₹600 crore budgeted again for FY27.

What would fix this
- MNRE should maintain a public, quarterly-updated register of green hydrogen and derivative projects under the National Green Hydrogen Mission, giving state, developer, capacity in MW and tonnes a year, and status from announced to commissioned or dropped, so the national map does not depend on a 2024 task-force list in which a third of rows lack capacity.
- The Odisha Industries Department should publish one consolidated list of green hydrogen and derivative projects approved by the state, with approval dates and investment, so the 9-project ₹1,53,000 crore and 12-project ₹84,918 crore rounds can be reconciled and duplicates removed.
- MNRE should report each year under the SIGHT scheme the electrolyser manufacturing capacity actually commissioned against the 3,000 MW awarded, and the green hydrogen actually produced against the 862,000 tonnes a year contracted, with incentives paid, so agreements and delivered output are not counted as the same thing.
