When petrol powered cars were introduced, petrol stations were not exactly plenty either.
In all cases, distribuution infrastructure has to be built, be it Hydrogen or electrical.
The problem with electric cars right now is that they take ages to recharge. What if you run out of energy in the middle of the way from you home to your holiday place? You NEED filling stations for electric vehicles too, and I am not talking about the standard 250 volt sockets that are already present. You will not be alone at the filling stations, there will be many others wanting to charge their cars too, meaning every filling station would have to get a high voltage connection, and a hotel to let you sleep while your car recharges.
The other method is changing the set of batteries, but that too would require special automated machinery to do it and it also would need the high voltage connection to charge the battery sets that are not in use.
And where do you think the electric enery would come from? It too would have to be produced by current energy sources (which you know are being depleted with every second). Having millions of electric cars all sucking on the grid would inevitably let the prices for electric energy skyrocket.
On the other end, Hydrogen is not more difficult to produce than petrol or diesel.
To gain Petrol or Diesel, you have to expensively search for new deposits of oil, then you have to build oil rigs to drill for it, then you have to transport the oil thousands of kilometres to each consuming country in huge expensive supertankers, then you have to expensively refine the oil into what you want to have. Is that easy or cheap? No, it certainly isn’t.
To get Hydrogen you build a collection facility in the sea, preferrably powered by wind, solar energy, or hydroelectrically (or by fusion when it becomes available) and extract the hydrogen with electrolysis. Then you can ship the hydrogen directly to the filling stations where the consumers can directly fill the hydrogen into their cars just as fast as with today’s petrol powered cars and don’t have to wait a night for recharge. It is actually a lot easier than making petrol or diesel and less expensive once the infrastructure has been developed.
For me, hydrogen power is the future, because for the consumer its use is identical to today’s petrol.
