True, but a gas can be compressed whereas a liquid can't, so a 50-litre
tank can contain 50 litres of petrol/diesel (very roughly 40 kg) but it
can contain far more than 50 litres of hydrogen because that can be
compressed to several atmospheres of pressure (limited by strength of
tank!) so you may be able to fit a greater weight of hydrogen in than of
diesel. I'm not sure what the typical tank pressure of hydrogen and LPG is

********. liwuid hydrigen is what you get at high perssure and liquid
hydrogen is 14 times lighterr than water for te smae volume whereas
diesel is about 0.9

In reality you need a 5 times bigger tank for hydrogen.
