You can liquefy hydrogen on the spot. You don't need to move LH₂ around. If that does become necessary, the solution is improved insulation. Modern materials can reduce boil-off to that of LNG's. In fact, LNG was once seen as impossible because of its boil-off concerns at one point.
You will need bigger tanks but the fuel is much lighter. It is a solvable problem.

Why are you liquefying H2 if you are using it right away and or not transporting it? Liquefaction is to optimize for storage. You're all over the shop.
- _hypx 3y agoYou liquefy H₂ for the density advantage, not for storage. You actually want to store hydrogen as a gas since it won't boil off.
