A couple issues have been mentioned, but what hasn’t been mentioned is that hydrogen is difficult to store, because the molecules are small enough do migrate through most containers and escape. If your container is made of metal, you also get something called hydrogen embrittlement which breaks your container over time.
It’s no more of a problem than dealing with LPG, surely? Pressurise it for storage.
I think it is, not sure but it requres bigger pressure and hidrogen is smallest atom that escapes even from high presure tanks.
You can’t keep liquid hydrogen by pressure alone and even as a liquid it’s volume density it’s very low compared to other liquids.
