Hydrogen fueling interaction
Client: Dover Fueling Solutions
Team: Carl Forslund, Melissa Ljung
Designed while employed at Zenit Design
Challenge
Hydrogen refueling involves unique technical risks and regulatory requirements, which can be intimidating for new users. The challenge was to create a system that could reduce user anxiety while reinforcing safe behaviours - especially under real-world conditions like time pressure, distractions or inexperience of refueling hydrogen. Additionally, the interface needed to integrate with Dover’s hardware systems and future product vision.
Goal
Redesigning refueling for safety, clarity, and clean energy adoption
Approach
We began with observational research from hydrogen fueling stations to understand how users currently navigate the process and where confusion or hesitation occurs. We also made a market analysis and benchmarking of existing fuelling interfaces and experiences. This led to the development of low-fidelity prototypes which were iteratively tested and refined. The interface design included a digital display that guided users step-by-step, reinforced by simple language, icons, and audio-visual feedback. Animated sequences were integrated to explain critical steps in a safe and engaging way.

Project outcome
The final design meets stringent safety standards while significantly improving user experience. It aligns with Dover Fueling Solutions’ vision of driving clean energy adoption through innovation and user empowerment.
This work sets a new benchmark in hydrogen fueling interaction design - making the technology more approachable, safer, and ready for further implementation.
