Levelised cost of ammonia
Levelised cost of green ammonia.
NPV-based LCOA from the cost of the hydrogen and electricity going into the plant, plus the synthesis loop, air separation, storage and balance of plant. See where the cost comes from and how it moves with the cost of hydrogen.

LCOA vs hydrogen cost
50% to 150% of the LCOH entered · all other inputs held constant · Umagine Hydrogen (UHPL)
Hydrogen is 85% of LCOA. Every ₹10/kg on LCOH adds ₹1,800 per tonne of ammonia; every ₹1/kWh on LCOE adds ₹650.
Umagine Hydrogen (UHPL) LCOA model, NPV-based: discounted lifetime costs ÷ discounted tonnes of NH₃. Hydrogen enters at the LCOH you set, which should be the cost of H₂ delivered to the synthesis loop (buffer storage included); electrolyser cost sits inside LCOH, so CAPEX here covers the synthesis loop, air separation, storage and balance of plant. Stoichiometric minimum: 177.6 kg H₂ and 822 kg N₂ per tonne of NH₃.
