is a bit of an understatement.

Consider that a household LNG gas cyclinder (propane if you're central north american I guess) is typically built to contain between 100 and 200 psi whereas hydrogen requires high pressure tanks to contain between 5,000–10,000 psi.

That's a factor of 50 difference in required containment pressure capability.

In Michael Liebreich’s Keynote Speech at World Hydrogen Congress 2022[0] he speaks about the problems of shipping hydrogen. you get around 1% of loss PER DAY (0.1% for LNG). And because of the huge tanks the energy capacity is 1/4 of a comparable LNG carrier. The economics just don't make sense.
