Hydrogen - Volumetric Energy Density
Volumetric energy density of hydrogen at various storage conditions - compressed, liquid, and cryogenic - compared to conventional marine fuels.
Density
71kg/m³
Volumetric energy
8.52GJ/m³
vs VLSFO volumetric
0.233 -
Formula, assumptions, and limits
Liquid H₂ volumetric energy ~1/4 VLSFO. 700-bar CNG ~1/13. Requires massive tank volumes and insulation for long voyages. Use cases: short-sea ferries, work boats (PEMFC).
