Not all hydrogen is created equal. The same molecule can be labelled green, blue or grey depending on how it was made — and that distinction determines whether it actually helps decarbonise transport, industry and power generation, or simply relabels fossil-fuel emissions. Green hydrogen, produced by splitting water with renewable electricity, is the version that matters most for a genuine energy transition, both as a clean fuel and as a way to store renewable power for later use.

This course from Arab British Fellowship Training Academy takes participants through the full green hydrogen chain: how it is produced through electrolysis, how it is stored once made, and where it is already being put to work. Participants leave with a grounded view of green hydrogen's potential to reshape the global energy landscape.
