But in this discussion we’re talking about using it for cargo ships specifically… That means hydrogen tanks in an enclosed environment if an accident ever happens and compressed it has even less energy by volume.
The volume doesn’t matter. Hydrogen can’t ignite without the presence of oxygen in the first place, and there isn’t any inside the tank. A new fully pressurized hydrogen tank is no more dangerous than a propane or natural gas tank. And we already ship natural gas in this state on specialized container ships.
If the tank leaks inside the ship is what I’m talking about, it’s not open to the air, the fuel reserve is inside the ship and there’s oxygen inside the ship. Hydrogen tends to leak a whole lot more than natural gas and an LNG cargo ship explosion is already a matter of concern.
