Platts to discontinue cost-based low-carbon ammonia and hydrogen assessments from Dec. 9

Platts, part of S&P Global Commodity Insights, will discontinue its cost-based low-carbon ammonia and hydrogen assessments, as well as its Carbon Neutral Hydrogen and Implied Hydrogen Origin Certificate assessments, in North America, Europe, Japan, Australia and the Middle East, effective Dec. 9, 2025.

This follows a note published on Sept. 15 proposing a discontinuation on Dec. 8. The discontinuation date has now been updated to Dec. 9.

Platts currently publishes production-cost assessments for conventional hydrogen, low-carbon hydrogen and electrolytic hydrogen. Platts notes that where underlying market liquidity permits, market participants have consistently expressed a preference for market-based price assessments. The discontinuation is intended to reflect this market need.

Platts has opened a consultation on the possible introduction of market-based hydrogen assessments in Northwest Europe and India. The consultation is accessible here.

This discontinuation does not include Platts' existing Renewable Fuels of a Non-Biological Origin (RFNBO) compliant calculated assessments that cover renewable hydrogen in France, Germany, the Netherlands and Spain.

Platts will also discontinue cost-based low-carbon ammonia assessments, as Platts already provides market-based price assessments for low-carbon ammonia.

The list of calculated price assessments to be discontinued can be found here.

These assessments can be found in Hydrogen Daily, and in the fixed pages CLE3100, CLE1100, ETA3300, CLE2100, ETA3200, ETA3100, and ETA3300.

The full list of affected assessments is included in the appendix.
