Thank you to our more than 350+ guests who joined us for the first HYDROVERSE CONVENTION, where we brought together start-ups and experts from the European hydrogen industry to share their insights, ideas and experiences.

Last year’s Convention provided a central stage for Europe’s up-and-coming start-ups in the industry to shine, while offering innovators, companies and investors the opportunity to exchange ideas and network. Due to its huge success, we’ll be back: Join us for the next round of hydrogen innovation on 18 June 2024 in Essen!

In the meantime, take a stroll down memory lane and discover our program from the first HYDROVERSE CONVENTION below.



Take a look at what our program had in store for visitors last year: discover hands-on pitches, thought-provoking panels and inspiring networking sessions. We designed the program to make a dynamic and engaging experience possible – for participants of all backgrounds and interests. Our program also included a dedicated networking area.
