The good thing is that you get a lot of energy density this way. The bad thing is that hydrogen is difficult to store, and you basically have a fuel-air bomb on your hand if anything goes wrong with your tank.

True, because it's hard to make materials that will hold it. It tends to damage metal and leak through other things.

No you do not, there is no air in your tank. Hydrogen is much safer than gasoline, if released it rises up in the air almost instantly. So a hydrogen fire would put itself out pretty quickly, and would not burn much that is around it.
