Swapping an engine into a Komatsu is sort along the lines of putting lipstick on a pig.

You need to ask where they get the hydrogen from...

The fallacy of 'zero emissions..." You're being lied to...

https://www.energy.gov/eere/fuelcell...tion-processes

99.9% of H2 if produced via natural gas reformation. aka blue Hydrogen.

Green Hydrogen which uses electricity to split hydrogen from water, is not
currently (pun intended) a viable option, we don't have enough electrical
generation to support it.

They are actually built too strong and ridgid. They continuously crack, so they are constantly needing cracks gouged and repaired.

The Cat haul trucks crack as well, but the frequency and size of cracks are usually lower, and overall they seem to get more ‘uptime’ and a longer overall lifespan.

Interesting.
Somewhere (maybe "Design News" magazine) was an article explaining how CAT
had changed from High Strength (T-100 maybe ?) to a lower strength steel
for the main frame, to lower the amount of cracks in the field.
