The Hydrogen & Carbon Capture Technology World Expo 2026 takes place from Tuesday 20 to Thursday 22 October 2026 at Hamburg Messe and is the world's largest trade fair for hydrogen and carbon capture technology. The organiser expects over 20,000 visitors, more than 1,000 exhibitors and more than 200 speakers. The event is organised by Trans-Global Events.
