World Hydrogen Summit & Exhibition 2027

The World Hydrogen Summit & Exhibition 2027, organized by the Sustainable Energy Council, takes place May 18-20, 2027 at Rotterdam Ahoy in the Netherlands, in partnership with the Port of Rotterdam. The organizers expect roughly 10,000 industry participants from 4,850-plus companies, with 500-plus exhibitors, 23-plus national and regional pavilions, and over 300 speakers including energy ministers, utility and industrial CEOs, and chief technology officers. Programming covers electrolyser manufacturing and cost curves, hydrogen derivatives and ammonia, offtake and bankability, port and pipeline infrastructure, certification and regulation, and industrial decarbonization in steel, chemicals, and heavy transport. It is positioned as the place where hydrogen offtake agreements and project partnerships are actually signed, which makes it worth the trip for founders selling electrolysis, storage, compression, or hydrogen-adjacent hardware into European industrial buyers.
