But what is the volume of a kilo of hydrogen at practical pressures?

• bildung 5y ago
  42 kg/m³ or 0.024 m³ per kg at the usual 700 bar.

  Looks like a ballpark, current practical volume is around 25 liters per kg: https://energies.airliquide.com/resources-planet-hydrogen/how-hydrogen-stored https://energies.airliquide.com/resources-planet-hydrogen/ho... I think the greater issue with Hydrogen is how it likes to go boom, and the greater the energy density you store it at, the bigger the boom!

    This is also one of the benefits of diesel, it doesn't ignite so easily.

    Actually Hydrogen without Oxygen doesn't make boom. Also Lithium batteries also have a tendency to go boom, so I guess that's equal.
