What is the primary engineering challenge presented by hydrogen when considered for deep-sea vessel design?
Answer
Extremely low volumetric energy density.
Hydrogen presents the greatest current engineering challenge due to its extremely low volumetric energy density, forcing designers to use either high-pressure tanks or energy-intensive cryogenic liquefaction.
