5. Conclusion

The difficulty of the paradigm shifts inherent in transition processes is clear. The transition to low-carbon mobility based on hydrogen in particular cannot be reduced to technological substitution. What we're talking about here is a change in the mobility system. This transition also requires a paradigm shift in the way these technological solutions are considered and designed. Designers cannot focus on technology alone.

Disciplinary openness, in particular towards the human and social sciences (SHS), is a very first step in this evolution, in order to design technological solutions in a human and social frame of reference different from that which prevails in the dominant model of carbon-based mobility, integrating a necessary global awareness of what is.
