Platts proposes to discontinue cost-based low-carbon ammonia and hydrogen assessments

Platts, part of S&P Global Commodity Insights, proposes to 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. 8, 2025.

Platts will consider all comments received and will make comments not marked as confidential available upon request.

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 proposed 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 proposal 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 is also proposing to 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 proposed under this discontinuation 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.

Please address any questions or comments to hydrogenassessments@spglobal.com and pricegroup@spglobal.com by Sept. 26, 2025.
