Helium was very rare and expensive back in the day, only the United States possessed it in large quantities. But the U.S. Navy refused to supply helium to Germany because Hitler and the German Reich had become too powerful for the Americans. Besides, the payload was far higher when filled with Hydrogen, which made the flight to Lakehurst and other far destinations possible and rentable.

I have heard that too, that US refused to deliver. But wasn’t sure if it was true.
Well, about the payload - the density of Helium is twice that of Hydrogen, both very light.
Without taking the structure of a Zeppelin in the calculation :
1 m3 Air weighs about 1,2 kg, so 1 m3 Hydrogen will lift 1,11 kg. And 1 m3 Helium 1,02 kg.
So Hydrogen is 8-9% better - when it doesn’t blow up 😊

Its Destination wasnt originally Lakehurst....It was NYC. The Empire State Building had a mooring station specifically for these ships. But on the Fateful Day, very high winds, possibly the sort known as a Microburst forbade the mooring of the Hindenberg. The closest Airship facilities besides 34th Street were the Naval Air Station at Lakehurst. The latest research I know of seems to put the blame on the skin covering of the Ship. Theory is the Finish, which was a combination of aluminum and magnesium helped create a buildup of Static Electrical discharges, one of which may have found a bare spot aft. The two paints are horribly Flammable. Once afire, it spread fast. Surprisingly few people died in the disaster. The Ship was a total loss, of course, and it spelled the end of the Airship as a general transportation vehicle.

A Few remained in service in the US Navy, which had been developing the dirigible as an aircraft carrier, until another crash grounded those that were left.
