That is a limitation of the pipeline infrastructure, because of hydrogen embrittlement of steel pipes. It is not a limitation of the large storage facilities, which are just exhausted natural gas wells and work just fine with hydrogen. The cost of outfitting one such facility with steel pipes that are not subject to hydrogen embrittlement is trivial compared to the cost for the electrolysis units etc. Note that I am not a big fan of hydrogen at all. But large scale storage is one of its few redeeming qualities.
