Hydrogen Powered ICE the future?

Wait a minute!  You're in the maritime world.  Stress corrosion cracking is your life....or, more correctly, the end of life for your equipment.

Not so much. With ships it's simple straightforward cracking due to fatigue loading at improperly designed joint details. That said ships that carry natural gas (LNG) need to worry about embrittlement over time but even they use independent tanks, so it is not the vessel per se that is directly in jeopardy.
