Green Ammonia Export Economics: At What LNG Price Does India's Grey Ammonia Lose Its Competitive Edge?
Green ammonia effectively carries zero CBAM exposure on EU exports. When fully phased in, grey ammonia produced from LNG will carry an implicit penalty of approximately €140–165 per tonne. However, under elevated spot market scenarios reaching $24–28 per MMBtu, grey ammonia production costs rise so sharply that the cross-over point—where green ammonia delivered to Europe is cost-competitive—arrives without relying solely on long-term CBAM penalties. This is the structural price analysis.
Key Takeaways
- Ammonia is India's largest CBAM-covered fertiliser product for EU export purposes — both as a direct product (anhydrous ammonia for industrial applications) and as embedded feedstock in urea and ammonium nitrate. CBAM Regulation (EU) 2023/956 explicitly covers ammonia (CN 2814), urea (CN 3102), and nitric acid (CN 2808), capturing the full direct exposure of the fertiliser sector.
- Grey ammonia production costs in India are entirely dominated by natural gas feedstock. Steam Methane Reforming (SMR) consumes approximately 25 to 27 MMBtu of natural gas per tonne of ammonia. At baseline Indian LNG spot prices of $10 to $12 per MMBtu, the gas cost per tonne of ammonia is roughly $250 to $324. However, under elevated market conditions reaching $24 to $28 per MMBtu, the gas cost per tonne exceeds $600 — dramatically inflating the overall grey ammonia production cost.
- While CBAM phases in slowly (starting at 2.5% of the emissions gap in 2026), EU buyers negotiating 10-year offtake agreements must price in the fully loaded future liability. The full CBAM cost on grey ammonia exports to the EU will eventually add approximately €140 to €165 per tonne (assuming EU ETS at €84.20/tCO₂e against a typical SMR emissions gap). In contrast, green ammonia produced via electrolysis carries a near-zero embedded emission below the EU benchmark.
- India's pioneering commercial-scale green ammonia projects are actively targeting initial capacities of 1 million tonnes per annum (MTPA) for export. The competitive advantage lies in utilizing coastal locations—such as Andhra Pradesh's wind-solar hybrid resources (with capacity factors of 45–50%)—alongside deep-water port infrastructure to minimize logistics costs to export markets like Europe, Japan, and Korea.
- Elevated LNG price scenarios create a near-term modeled advantage for green ammonia projects that were previously considered commercially marginal. The Indian government's SIGHT programme production incentive (approximately $105/t in its first year) helps close the remaining premium, making SIGHT-supported green ammonia commercially viable during periods of high natural gas costs.
- The critical risk to green ammonia's export competitiveness is LNG price normalization. If global gas markets stabilize and LNG spot prices return to $15 per MMBtu, grey ammonia production costs will fall back to roughly $625 per tonne. At that baseline, early-phase green ammonia remains structurally more expensive until the full punitive weight of the CBAM tax goes into effect in the early 2030s.
India's green ammonia export opportunity sits at the intersection of three converging forces. The first is CBAM — which has converted the clean status of green ammonia from a theoretical CSR advantage into a hard financial prerequisite for long-term European offtake agreements. The second is the volatility of the LNG market — where supply shocks can dramatically increase the baseline production cost of grey ammonia, masking the green premium. The third is the green ammonia demand pull from industrial decarbonisation in Japan, Korea, the EU, and Singapore — markets where ammonia is increasingly procured as a zero-carbon maritime fuel and hydrogen carrier.
The grey-green ammonia break-even model
• Gas feedstock at $26/MMBtu: 26 × 26 MMBtu/t = $676/t
• Other variable costs (power, water, catalysts): $60/t
• Fixed costs (capital amortisation, O&M): $80/t
• India-to-EU shipping (40-day voyage): $95/t
• Projected full CBAM liability (gap vs benchmark at €84.20): €185/t (~$200/t)
Total grey ammonia delivered to EU: ~$1,111/t
Green ammonia (India, electrolyser, solar+wind hybrid):
• Green H₂ production cost (current, unsubsidised): $5.50/kg H₂
• H₂ to ammonia conversion (~176 kg H₂/t NH₃): $5.50 × 176 = $968/t
• Fixed costs + Haber-Bosch + N₂ separation: $120/t
• SIGHT incentive (Year 1, Rs 8.82/kg of NH₃ ≈ $105/t): −$105/t
• India-to-EU shipping: $95/t
• CBAM certificate obligation: ~$0/t (near-zero emission)
Total green ammonia delivered to EU (SIGHT Year 1): ~$1,078/t
GREEN ADVANTAGE at current $26 LNG and full factored CBAM: ~$33/t delivered
Break-even LNG price risk (if LNG normalises to $15/MMBtu):
• Gas feedstock at $15/MMBtu: 15 × 26 MMBtu/t = $390/t
• Grey total without CBAM = $390 + 60 + 80 + 95 = $625/t
• Grey total with fully-loaded CBAM (~$200) = $825/t
Conclusion: If global LNG markets stabilize at $15/MMBtu, grey ammonia ($825/t) maintains a strong competitive edge over early-stage green ammonia ($1,078/t), even when saddled with the maximum future CBAM penalty. For green ammonia to win without subsidies at $15 LNG, Green H₂ production costs must fall closer to ~$4.00/kg.
Frequently Asked Questions
Is India's CBAM-free green ammonia advantage permanent?
Yes, structurally — but the magnitude of the advantage depends heavily on the phase-in schedule and EU ETS prices. While importers only pay 2.5% of the CBAM exposure in 2026, long-term offtake agreements spanning into the 2030s must price in the full 100% phase-in. Green ammonia's near-zero embedded emission will always have lower CBAM exposure than grey ammonia's typical ~2.0–2.5 tCO₂e/t footprint. As EU ETS prices are projected by analysts to rise toward €120 to €150 per tCO₂e by 2030, the CBAM penalty on grey ammonia will widen, creating a permanently increasing structural advantage for green alternatives.
Which Indian ports are best positioned for green ammonia export?
Kakinada and Krishnapatnam in Andhra Pradesh are primary candidates for greenfield export terminals. This is due to the region's superior wind-solar hybrid resource (annual capacity factor 45 to 50 percent), land availability for large-scale electrolysis, deep-draft port infrastructure for ammonia tankers, and direct proximity to Bay of Bengal shipping lanes leading to Japan, Korea, and Singapore. Kandla in Gujarat serves as a strong secondary candidate for the EU-bound trade, benefiting from proximity to Rajasthan's solar resource and existing chemical port infrastructure.
