The infrastructure is much more expensive, and I suspect the government funding to get it off the ground hasn't been big enough to truly kick-start things.
However, I wonder if we aren't approaching a point where adding EV charging capacity becomes harder so there might become an opportunity for hydrogen to gain a foothold. The National Grid needs upgrading to support significant EV charging, both in terms of transport capacity, storage and generation. You read stories that solar installations can't get connected to the grid for example, and while renewables are growing the storage to match generation and demand isn't.
It will be interesting to see what impact Zebra funding has on the grid. Am I right in thinking most funding went to smaller towns and cities? I do wonder what will happen if somewhere like Manchester decides to go all-in on EVs for example. Installing chargers is one thing, getting them grid connected is another.
