Latest results from hydrogen electrolysis research show 95% efficiency on theoretical limit converting electricity to hydrogen.
The current mass market fuel cell conversion from hydrogen to electricity is about 70% efficiency.
I am under the impression that hydrogen storage and transport for static usages are not that significantly different from natural gas. Or natural gas facilities can be converted to manage hydrogen with relatively small cost.

Hydrogen takes up around 3.3x more volume for the same amount of energy storage as SNG. If you have a lot of energy that costs you essentially zero in some parts of the summer storage costs can become more important than efficiency.
I confess I do not know what they mean by that precisely, but I am under the impression that hydrogen storage as low pressure gas is very viable
In fact I if the pipeline can handle town gas, I don’t see why both hydrogen and natural gas can not be produced at the same time, to hit the pareto efficiency. Natural gas more heat storage per volume, hydrogen better heat storage efficiency, depending on storage capacity, projected energy production and usage a theoretically optimal mix can be calculated.

according to wikipedia, pipeline storage of Germany is currently capable of several months
