Startup from France NamX showed a crossover on removable hydrogen cartridges
It is reported that the cartridges can be hidden in the bumper, and they leave at the touch of a button. Cylinders can be easily filled or replaced at a special station. If there is no such nearby, then they will be sent by couriers. They want to launch the project into mass production in 2025 - the price is 65 thousand euros.
