Here's a basic electrical reality, amps do the work and voltage pushes the amps to do the work. So the higher the voltage the less amperage you need to do the same work. Modern cars and trucks really need 36~48 volt systems but we (the US) are stuck with 12volt systems for the foreseeable future. Higher voltage would give us faster cranking speed by increasing starter RPM and increasing starter horsepower. Both good things for a cold and stiff diesel, to make starting it way easy on cold mornings.
ok, so here's the next question. why multiples of 12?...24, 36, 48. you could easily build a system like that and get a custom starter... big money, i suppose, and you'd need engine space to run 3 or 4 alternators!

Delco makes 24V alternators for the big diesel trucks and industrial equipment already. It would not take much to change the electronics and get 36 or 48V either.

There are also some 8volt batts out there too, golf carts I think. Most battery cells are 2 volts each so multiples of 2 are easily done.
If I remember this right most alternators put out AC current but its switched inside the unit by the diodes to make DC output...

The NATO standard 24v is helpful where more starting power is needed, for the big trucks (deuce, 5-ton and up), and it pays to be able to jump the little trucks off the big trucks, or vice versa, in a pinch, rather than having to hunt up another truck that's the same voltage. On the base, no biggie, in the field, all bets are off, more standardization is better.
People who somehow think the 24v starter is necessary in any way on a 6.2 are idiots, there are plenty of 6.2, 6.5 and other diesels in use EVERY SINGLE DAY, all over the world, hot and cold, that start just fine on 12v.
I have no idea whether automotive electrical systems elsewhere in the world are 12v, 24v or anything else, nor do I care. Wouldn't surprise me if they were 24v, just like the rest of the world uses 240v house current and we use 110v.
At the end of the day, it really doesn't matter. I'll be converting my truck to 12v when I need to replace the starter, most likely. Maybe sooner, so that I can sell off the working 24v unit to somebody who wants to retain the 24v system.
