India's Green Ammonia Cost Stack: From SECI Auctions to European Markets

June 2026 research release. India has discovered a credible domestic green-ammonia cost floor. The export question is whether those projects can become buyer-grade RFNBO files before the 2028 grandfathering window closes.
Why the March 2026 signing changes the story
On 30 March 2026, the Ministry of New and Renewable Energy presided over a CEO-level signing ceremony at which parties formally exchanged Green Ammonia Purchase Agreements (GAPAs) and Green Ammonia Sale Agreements (GASAs) for 11 of the 13 SECI Mode-2A projects. The press release is public record: PIB PRID 2247064.
That event converts most of the auction book into signed domestic supply: 670,000 TPA signed out of 724,000 TPA allocated. The price band is INR 49.75 to 64.74 per kg ex-works, roughly $568 to $740 per tonne. The H2Global Egypt Lot 1 clearing price is EUR 1,000 per tonne delivered into Europe, or about $1,080 per tonne. At factory gate, India looks deeply competitive; on a delivered-Rotterdam, RFNBO-certified basis, the same molecules land at about $886 to $1,228 per tonne.
The instinct is to read this as India winning on cost. That is the wrong frame. These contracts are domestic by design: SECI is the buyer, fertilizer plants are the offtakers, and SIGHT subsidies underwrite the first three years. None of these contracts will deliver a tonne of ammonia to a European port. None carries RFNBO certification. The gap between INR 57 per kg ex-works Kakinada and EUR 1,000 per tonne delivered Rotterdam is not primarily a production-cost gap. It is a compliance-and-delivery gap.
The SECI cost stack
The 13 auctions cleared in an unusually narrow band for an infrastructure tender of this scale. Excluding the outlier Auctions 10 and 11 (low-volume residual lots at Zuarinagar and Haldia), 11 of the 13 cleared between INR 49.75 and 57.65 per kg. The tightness of the band is its own data point: multiple bidders converged on a shared view of what a coastal 10-year GAPA is worth at current Indian solar tariffs (INR 2.30 to 2.65 per kWh) and current electrolyzer import economics.
ACME Cleantech holds the structural position: six wins totalling 370,000 TPA, which is 51 percent of the allocated capacity. The next tier is Jakson Green, NTPC RE, and SCC + InSolare, each with one or two wins in the 50,000 to 85,000 TPA range. No other bidder took a material position.
The geography matters as much as the bidder roster. Eleven of thirteen GAPAs concentrate in a coastal arc from Kandla (Gujarat) through Paradeep (Odisha) to Kakinada (Andhra Pradesh), with two inland clusters at Sagar/Dhule (Madhya Pradesh) and Meghnagar/Bharuch on the Gujarat-MP industrial corridor.
The buyer-side price gap
The right way to understand why SECI-at-INR-50-per-kg does not export directly to Rotterdam is to break down the delivered cost stack segment by segment. Every segment is a separately engineered workstream, and each has its own source of uncertainty.
Loading cost stack waterfall...
The headline reading: RFNBO readiness is the single largest controllable cost between SECI-cleared and Rotterdam-delivered. Ocean freight is larger in absolute terms, but it is a market rate set outside any single project's control. RFNBO architecture, by contrast, is an upfront engineering choice. Battery storage to satisfy hourly temporal correlation, oversized renewable capacity to satisfy additionality, PPA structure to satisfy geographical correlation: all of these are capex decisions. Projects that clear FID before 2028 can make them cleanly; projects that miss grandfathering make them expensively; and projects already committed to SIGHT-subsidised inputs that violate EU additionality rules can contractually never make them.
The RFNBO to GHCI gap that 11 of 13 now face
India's GHCI framework sets carbon intensity at 2.0 kg CO2eq per kg H2. RFNBO sets 3.38 kg CO2eq per kg H2. On the raw threshold, India is stricter. That is the easy reading and it is incomplete.
RFNBO has three additional provisions that have nothing to do with the carbon intensity number itself:
- Additionality. The renewable power supplying the electrolyser must be incremental; projects cannot draw on subsidised capacity that existed before the hydrogen plant was approved. India's SIGHT scheme is a renewable subsidy. For all 11 signed projects, the SIGHT-subsidised input architecture has a potential additionality conflict with EU RFNBO rules.
- Temporal correlation. Monthly matching until January 2030, hourly matching from 2030. SECI wrote the contracts with no temporal constraint; retrofitting hourly matching after FID is structurally harder than engineering it before FID.
- Geographical correlation. Renewable power and electrolyser must sit within the same bidding zone. India's grid uses multiple bidding zones; the EU assumes a single zone. This becomes a design constraint that developers must resolve at the PPA structure level, not at the MRV layer.
On the carbon threshold, India is stricter. On the full RFNBO stack, India is not compliant, and there is no path to compliance without upfront design work on the PPA, the electrolyser siting, and the RE architecture. The grandfathering window closes 1 January 2028.
Three project archetypes and where they stand
Not all 11 signed projects sit at the same distance from an EU-ready file. Checking these projects against the ten buyer-side filters used by Uniper, Yara, Hintco, and OCI yields three archetypes.
Archetype I: integrated sponsor, coastal, buyer-ready within 12 months. Jakson Green Kakinada (85,000 TPA) and ACME's coastal complex at Kandla, Vishakhapatnam, and Paradeep. Coastal siting is resolved. Sponsor balance sheets are material. Electrolyser and EPC relationships are further along. The remaining gap is RFNBO architecture, which is a structured 12-month programme rather than a multi-year rework.
Archetype II: inland SIGHT winner, domestic-only by default. Oriana Power Sagar, SCC + InSolare Dhule, NTPC Meghnagar, Onix Bharuch. Inland siting forces a domestic transport leg before the port. Viable for export but carries a $25 to $40 per tonne logistics penalty plus the RFNBO upgrade.
Archetype III: edge cases not credibly export-ready in the near term. Suryam Int'l Chennai (4,000 TPA), single-offtaker sub-scale allocations. Phase-1 domestic-only by design.
The full typology, including the buyer-filter scorecard and project archetypes, sits in Appendix B of the HyGOAT Research briefing now linked below.

HyGOAT view: the narrow wedge
This section is a view, not data. It is separate from the database.
HyGOAT's position is that the window between April 2026 and January 2028 is the forcing function for every India-origin green ammonia project that wants a Phase-2 export pathway. Not because buyers are scarce; Uniper, Yara, Fertiglobe, OCI, RWE, Neste, BASF, and Hintco are the named near-term buyer pool, and several have open capacity for the right molecule. Scarce is the pool of India-side projects that arrive at a first buyer conversation already RFNBO-ready. AM Green Kakinada cleared RFNBO pre-certification in June 2024, fourteen months before the 500,000 TPA Uniper SPA signed in January 2026. That sequence repeats: certification confidence unlocks deals, introductions do not.
The implication for HyGOAT is narrow and specific. HyGOAT is not a broker, not a trader, and not a certification body. HyGOAT is an RFNBO-readiness and buyer-grade project qualification partner for India-origin green ammonia projects targeting Europe. The mandate is to engineer the RFNBO architecture, assemble the buyer-grade data room, coordinate certification-body engagement, and bring 5-of-6-gate-qualified projects to the pre-mapped European buyer universe. The monetization sits on the developer side; buyers pay nothing in Year 1. Pricing blends a fixed diagnostic fee, a retained mandate, and milestone-based advisory fees on LOI and SPA events.
That is the narrow wedge. It is deliberately narrower than "offtake origination" because offtake origination as a standalone service does not scale as a startup, and the market has seen too many bilateral-deal-facilitation pitches in hydrogen since 2019 to take a broad one seriously. RFNBO readiness is a specific, defensible, compliance-anchored job that maps cleanly onto HyGOAT's existing certification expertise.
