We use fewer critical raw materials for our fuel cell, unlike the lithium and cobalt typically used in batteries. Our use of these materials is considerably reduced.

Sodium batteries won't help here as they are even more heavy.

For the infrastructure, for long-distance transport, we need approximately 140 filling stations across all of Europe. That's a completely different scale than for battery-electric cars. In other words, there isn't that much to do.

In Germany alone there are about 14000 gas stations, 350 at the Autobahn; housing some of the 160000 charging points.

Modern trucks don't use cobalt batteries. LFP are better for that workload as they can be cycled much deeper (making up almost all the weight difference when just looking at nominal capacity) and are substantially safer and actually somewhat cheaper than the NMC chemistry that uses the cobalt.

And lithium itself is not nearly that rare.
