What to read next, and where to go for the things this site does not do

International Energy Agency · iea.org

The most complete public register of announced and operating hydrogen production projects worldwide, with capacity, technology, status and start-up year. Updated roughly annually and released under an open licence, which is why it can be quoted rather than only linked.

IRENA · irena.org

Installed renewable capacity by country and technology — the denominator behind any electrolysis load-factor assumption. No open licence, so link to it rather than reproducing the tables.

International Partnership for Hydrogen and Fuel Cells in the Economy · iphe.net

Government-submitted country profiles, including the UAE's. Useful because the text is written by the national administration itself, which makes it citable as an official position rather than commentary.

UAE Government · u.ae

The primary source for every UAE target on this site. Note that the government portal and the strategy document itself differ on the 2050 figure — 15 against 14.9 Mt/yr — so cite whichever you actually read.

ISO · iso.org

The international methodology for quantifying the greenhouse gas footprint of hydrogen production and delivery. Replaces the 2023 technical specification. If an offtaker asks how your carbon intensity was calculated, this is the answer they expect.

CertifHy · certifhy.eu

The European scheme most often named in offtake negotiations, covering both renewable and low-carbon scopes.

European Commission · energy.ec.europa.eu

The Commission's list of schemes recognised for RFNBO compliance. If a scheme is not on this list, it does not get you into the European market.

TÜV SÜD · tuvsud.com

The certifier behind the UAE's own certified ammonia cargoes to Japan and Germany.

EUR-Lex · eur-lex.europa.eu

The additionality, temporal correlation and geographic correlation rules that decide whether hydrogen counts as an RFNBO. Read this before modelling any European offtake.

EUR-Lex · eur-lex.europa.eu

The greenhouse gas saving threshold and the methodology for calculating it.

EUR-Lex · eur-lex.europa.eu

Hydrogen and fertilisers are both in scope, so this prices the embedded carbon of anything a Gulf exporter sends into Europe.

European Commission · energy.ec.europa.eu

The industrial and transport RFNBO sub-targets that create European demand in the first place.

European Commission · energy.ec.europa.eu

Fixed-premium auctions that set the only transparent European clearing prices for renewable hydrogen. The published results are the closest thing the sector has to a price signal.

Hydrom (Oman) · hydrom.om

Oman's auction portal, and the only Gulf mechanism that has actually allocated land and published committed capacity by block.

NREL / US Department of Energy · nrel.gov

The reference public model for hydrogen production cost, maintained by NREL with DOE backing. Models, case studies and documentation are all available at no cost. If you need a defensible LCOH and have a spreadsheet, start here.

NREL · nrel.gov

A simplified browser version of the same methodology, for a first-pass estimate without building a full model.

US Department of Energy · energy.gov

The methodology documentation behind H2A — assumptions, boundaries and what the models do and do not include.

Nature Communications Earth & Environment · nature.com

A published, reproducible framework combining open tools for siting and evaluating green hydrogen production. Useful when you need a method a reviewer can check.
