- tambourine_man 4y agoIt’s very, very different: −160 °C vs -250 °C and liquid density of 450 vs 70 kg/m3
- ncmncm 4y agoBoth are easily carried in a Dewar flask. LH2 takes up more room, but that is just a matter of how big the ship carrying your flasks is, and how many of them. The number of kg in a flask of some volume is much less, but you also need to oxidize many fewer kg to get the kWh you paid for. The ratio is not 1, but is much less than 450/70. There is nothing special about the size and laden mass of the LNG vessels we use. It was chosen by immediate convenience. Details of vessels for LH2 will be chosen the same way.
