HyXchange HYCLICXDutch electrolysis marginal-cost indicator, €/MWh HHV. Daily automated "PLUS" series published since 1 January 2026; hourly data available on request from the HyXchange team — no public API. Status: not yet integrated.
EEX HYDRIXEuropean Energy Exchange's real-time hydrogen price index, in XML/JSON/CSV. The EEX webshop states it is free of charge until further notice; terms should be re-checked before relying on it. Status: not yet integrated.
CEGH GreenHydrogen IndexAustrian cost-plus index for green hydrogen — PPA 100% (RED II compliant), PPA 40, spot, and an 8-point forward curve. Scraped from CEGH's public page (server-rendered HTML tables, no API needed) by scripts/price_scraper.py. €/MWh converted to €/kg at 39.4 kWh/kg HHV. Status: integrated — live, shown on the home page.
IEA Global Hydrogen Review, via ACER CHESTProduction cost ranges (EUR2024/kg) by technology, 2024 vs. a 2030 projection. ACER republishes the full IEA dataset as a plain HTML table — no login or CSV-export flow needed. Scraped by scripts/iea_cost_scraper.py, grouped into grey (gas/coal without CCUS), blue (gas/coal with CCUS), and green (solar, onshore/offshore wind) ranges. Not a live price — a periodically-updated benchmark. Status: integrated — shown on the home page.
Industry surveysCountry-level $/kg benchmarks (e.g. Expert Market Research) used for grey/blue/green comparisons outside Europe, where no public index exists. Status: not yet integrated.
Checked and ruled outChina's "Hydrogen Price Index" (SMM/metal.com) has real numbers but an explicit no-copying notice and a partial paywall — not scraped. Japan/Korea have no free hydrogen $/kg index (Argus/Platts price ammonia, not hydrogen, and are subscription-only). EU Hydrogen Bank and UK HAR auction clearing prices are real but one-off events, not a continuous series — candidates for the news feed rather than the price tables.
