Nothing to do with anything - prompted by mention of the 'hydrogen economy'.
The green space generally abounds with bogus myths e.g. "BEV charging times will improve over time" (no they will not), BEVs will save the planet reduce carbon emissions (no they won't, emissions are simply be displaced in time or geography and over the life cycle of the product if anything will be greater - even before we get to the end of life problem posed by 400/500kg batteries full of toxic/combustible materials, etc.
However the super charlatans of the green space are those suggesting there is going to be a 'hydrogen economy'. This is NEVER going to happen. There are two problems with hydrogen.
First pure hydrogen exists nowhere in nature. To isolate hydrogen you need to expend a lot of energy to wrench it away something that it was originally combined with. The process is inefficient so the latent energy in the hydrogen produced is less than the energy required to produce it. Thus fairly pointless but you end up with something that is akin to a battery.
Secondly hydrogen loathes to infinity being alone. Fortunately for hydrogen as the smallest element in the periodic table it is super well positioned to infiltrate/attack/combine with anything it comes into contact with. This makes it very difficult to store/contain/transport. As from the previous problem there isn't a big win in producing pure hydrogen, the two problems together mean the technology isn't a practical flyer.
So if anyone offers you the chance to get in at the ground floor on something that will be BIG in the hydrogen economy - walk away, they are playing you for a fool.
