Bad news for gas engines converted to run on hydrogen.
Hydrogen Embrittlement has been detected in some engine components, in some cases severely.
It occurs when Hydrogen gas dissolves into the structure of certain metals (usually Aluminum & Steels).
It can cause cracking and failure of metal components.

Hydrogen Embrittlement - A type of deterioration which can be linked to corrosion and corrosion-control processes. It involves the ingress of hydrogen into a component, an event that can seriously reduce the ductility and load-bearing capacity, cause cracking and catastrophic brittle failures at stresses below the yield stress of susceptible materials.
Hydrogen embrittlement - Entry at Wikipedia.
http://switch2hydrogen.com - Bob Lazaar's hydrogen kit company is now looking into this problem, possible solutions, and are performing a tear-down of our vehicles that have clocked the most miles on Hydrogen.
Xado Prevents & Repairs Hydrogen Embrittlement - Xado is an energy saving product which also prevents hydrogen embrittlement by coating engine with a ceramic base which hydrogen is not able to react with. Xado repairs hydrogen embrittlement damage by filling grooves and crevaces and fills with a ceramic coating.
Hydrogen embrittlement not a substantial threat - Hydrogen-conversion expert, and clean-fuel specialist, Tai Robinson, responds to assertion that when hydrogen gas dissolves into the structure of certain metals such as aluminum & steels, it can cause cracking and failure of metal components.
