About the sprint
H2UB SPRINT is Europe’s most targeted program for hydrogen start-ups, combining deep industry mentoring, strategic refinement and corporate access to help teams progress toward real-world pilots and venture client engagement.
We bring together sector experts, technology leaders and corporate practitioners who challenge assumptions, sharpen value propositions and provide real industrial insight.
You will collaborate closely with these experts to refine your market fit, validate use cases and strengthen your commercial strategy.
Through targeted access to corporates, you will gain a clear understanding of industrial requirements and move toward concrete collaboration opportunities — from pilots and PoCs to long-term partnerships.
The result: a defined pathway from validated technology to practical deployment and measurable impact in the hydrogen ecosystem.
Key benefits
The next SPRINT will start in April 2026 - stay tuned for more information about the start of the application phase!
FAQ
Who is eligible to attend the SPRINT?
The SPRINT is open to start-ups from all over Europe, which are at the Seed to Series A/B stage. Technology readiness should be at level 4 (minimum), preferably at level 6 or 7.
How much does it cost to attend the SPRINT?
Participation is free. We also cover your travel expenses according to our Travel Expenses Guideline after you have completed the program. That means you get free access to services and contacts.
Why should I participate in the H2UB SPRINT and not in another H2 accelerator?
Hydrogen related innovations take time, are risky and need strong partners to scale. Furthermore, the market need is still blurry and unclear. Unlike other accelerators, we offer access to senior industry experts who provide specific sector knowledge and open doors for pilot projects and cooperations.
