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.
