>> Or maybe I'm wrong and somebody comes up with an easy and cost effective way to store significant amounts of hydrogen
>We already do it for natural gas (LNG), we just need to build similar infrastructure for LH2.
That doesn't address the "easy and cost effective" part. Current estimates say that the energy required is 30% of the energy value of the hydrogen itself.
>But whereas liquefying natural gas only requires temperatures of -160°C, to liquefy hydrogen you need refrigeration systems capable of getting down to -253°C. That is an expensive proposition. Using current technologies the energy required is 30% of that in the hydrogen being liquefied.
