A gas line in your basement! What could possibly go wrong! Come on...

Hit NG with a spark and see what that’s like!

Let’s see, there are buses running around on the streets with compressed NG systems in them... I see they make the news every night because they’re blowing up all over the place.... /s

Would there have to be proper containment system for the hydrogen? YES! Is it a hugungus undertaking... No! It’s no more of an issue than an above ground liquid propane tank.

The horror! Those things explode all the time right? /s

The ISSUE is hydrogen embrittalment. THAT shortens the usable life of the system.

The mainteneance on the fuel cell: THAT shortens it!

Take your Hindenburg and stow it!

Here's a quarter.

Buy yourself a sense of humor.

Absolutely wrong. Propane is liquid under reasonable pressure at room temperature. Liquid hydrogen turn to gas at -423F. Extreme cryogenics. PLUS liquid H2 takes up a lot of space to quote

The density of liquid hydrogen is only 70.99 g/L (at 20 K), a relative density of just 0.07. Although the specific energy is around twice that of other fuels, this gives it a remarkably low volumetric energy density, many fold lower.
SO NO there really isn't a great deal of similarity between propane and liquid hydrogen.

I've worked the design of propane and hydrogen storage and pumping/compression systems.

It is a heck of a lot more complicated and expensive than storing propane. Compressing it to a usable volume, the ease hydrogen leaks from systems due to the small molecule size are examples. Also the Group B rating for the Hazardous Area Classification makes equipment more expensive to manufacture.

Storing propane and hydrogen are two very different things. Propane is easy to maintain as a liquid at relatively high pressures, not so hydrogen. If fact hydrogen is very difficult to hold as a gas because of its low molecular weight.

Hydrogen has the added danger of producing an invisible flame, not so propane.
