At this year’s Hydrogen Technology Expo 2025, REJOOL proudly unveiled its latest innovation: a portable hydrogen refueling unit designed for drone applications. The system marks an important step toward flexible and emission-free hydrogen mobility — even for small, unmanned aerial vehicles.

Fast and Safe Hydrogen Refueling

Developed for rapid refueling at 350 bar, the new REJOOL unit enables safe, oil-free hydrogen compression and dispensing wherever it’s needed. The fully automated operation ensures reliability and repeatability, making hydrogen refueling as simple as charging a battery — but with significantly greater energy density and endurance.

Collaboration with ZAL – Hamburg

During the HTE 2025, the portable refueling system was demonstrated together with a hydrogen-powered drone from ZAL (Zentrum für Angewandte Luftfahrtforschung, Hamburg). This demonstration attracted strong attention from visitors and experts alike, highlighting the potential of mobile hydrogen infrastructure for next-generation aerial applications.

A Step Toward Hydrogen Everywhere

With its compact design and oil-free operation, the REJOOL portable hydrogen refueling unit offers a scalable solution for diverse use cases — from drone research and testing to field operations, microgrids, and off-grid energy systems.
