DNV Report Finds Hydrogen Ships Face Major Safety Cost Hurdles
A landmark DNV safety study commissioned by European maritime regulators concludes that hydrogen-fueled ships require extensive engineering redesign that will add substantially to vessel costs, complicating the fuel's decarbonization case.
Key Takeaways
- DNV's EMSA-commissioned study finds hydrogen shipping requires fundamental vessel redesign, not just fuel system swaps
- Hydrogen's wide flammability range (4–75% in air) and molecular permeation demand costly containment and ventilation systems
