As shipping looks to liquefied hydrogen as a way to move the zero-carbon fuel on long-haul routes, a key challenge is the fast rate at which the cargo is lost to boil-off when shipped at intensely cold temperatures.

Classification society ABS recently unveiled a concept design of an 80,000-cbm liquefied hydrogen carrier that aims to overcome that problem by using technology deployed by the National Aeronautics and Space Administration (NASA) to store hydrogen fuel.

However, using space tech to move hydrogen at -253C does not come cheap.
