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
