Platts updates renewable ammonia assessment capex and WACC figures, April 1
Platts, part of S&P Global Energy, has updated its capital expenditure and weighted-average cost of capital figures, which are used in the calculation of renewable ammonia assessments as part of the annual review of the Platts Hydrogen Methodology, effective April 1, 2026.
With this update, Platts reflects current pricing for stacks as original equipment manufacturers move toward more standardized, modularized solutions for installing electrolyzers at renewable hydrogen and ammonia projects. These updated capital expenditure and financing costs are based on industry input and feedback.
The updates are as follows:
| Description | Symbol | Old | Updated | Change % |
| Alkaline Electrolyzer System Efficiency (%, LHV) | HVNEB00 | 60% | 71% | 18% |
| Alberta Hydrogen Alkaline Electrolysis Capital Cost ($/KW) | HYITC00 | 2344 | 1805 | -23% |
| Western Australia Hydrogen Alkaline Electrolysis Capital Cost (A$/KW) | HYXAV00 | 2592 | 2247 | -13% |
| Saudi Arabia Hydrogen Alkaline Electrolysis Capital Cost ($/KW) | HYSCB00 | 1694 | 1275 | -25% |
| US Gulf Hydrogen Alkaline Electrolysis Capital Cost ($/KW) | ACSTH00 | 1711 | 1656 | -3% |
| Post-Tax Real Weighted Average Cost of Capital Australia | PTRCA00 | 6.3% | 5.6% | -11% |
| Post-Tax Real Weighted Average Cost of Capital Canada | PTRCC00 | 6.4% | 4.2% | -34% |

| Post-Tax Real Weighted Average Cost of Capital United States | PTRUS00 | 7.1% | 5.3% | -25% |
The primary affected assessments are as follows. The corresponding unit-of-measurement conversions and monthly averages have also been affected.
| Description | Symbol |
| Australia Renewable derived Ammonia delivered into Far East Asia - High Capacity Factor $/mt Wkly | GADAB04 |
| West Coast Canada Renewable derived Ammonia delivered into Far East Asia - High Capacity Factor $/mt Wkly | GADAD04 |
| Middle East Renewable derived Ammonia delivered into Far East Asia - High Capacity Factor $/mt Wkly | GADAH04 |
