P.47-6
Storing hydrogen as a cryogenic liquid is assumed to be
impractical
for underwater applications owing to the extremely low temperatures required.
Hydrogen has a very low boiling point at 1 bar of 20 K (-253 oC) and
therefore special insulated containers are required, with attention being
paid to the hydrogen lost due to boil off.
P.47-7
Howaldtswerke Deutsche Werft (HDW) have developed an air-independent-propulsion
(AIP) system for the Class 212 submarine [3,4] in which
the hydrogen is stored
as a metal hydride. This submarine will have 18 hydride tanks, each weighing
4.4 tonnes, with a volume of 1200 litres, and capable of providing 1 MWh of
energy per container. The metal hydride is heated by the fuel cell cooling
water system to provide the energy for endothermic dehydrogenation.
所以人家根本不要用液态氢，而是其他的储存形式，并且可以带将近40吨的金属氢化物

1F：→ MOONRAKER:这不是80年代很红的氢吸收合金 4.4吨一千度感觉满少的… 06/10 09:28
2F：推 kimfatt:4400kg:1200L(84kg) 52:1 好少 记得一般乾式储存是8:1 06/15 21:07
3F：推 kimfatt:照算 84kg的氢 应该有84*140MJ = 11760MJ = 3.26MW才对 06/15 21:10
