Price per BTU is important. Propane is half the cost of Diesel per btu.
Propane is very clean if you can use vapor.
If you need it at the super cold temps you will want a liquid pickup. That
will have to be filtered and then vaporized.
Takes a bit of energy to start the vaporizer but once the engine is running the
water jacket will do the job.
Most standby generators heat the waterjacket anyhow so it will probably not
need external power for the vaporizer.
Propane powered trucks use a liquid pickup.
Yes, you can run a semi off of propane, but you have to blend it with a bit of
Diesel.

Regardless of maintenance and upkeep, the thing I can see right up front would
be energy density. How many propane semis are there?

I have noticed that large generators everywhere seem to all be diesel, and
it’s something I’ve often wondered about. Propane can be stored for decades.
Diesel breaks down, gels, and grows algae. So I’ve always gone with propane
and just got the oversized tank. I can’t imagine a heater for the tank is that
huge of a problem (but I’ve never done it either).
What is it that makes diesel more attractive for the larger generators?

You can do something for it - heaters or maybe an additive. Keep in mind all
the really big data centers are all diesel (remember when NYC went dark during
the hurricane?)

Wouldn’t diesel gel at -20F?

When I looked at propane for a standby generator at the data center I
calculated it out as a 3000 gal tank at -20F to be able to provide sufficient
flow for a 125k generator. Or it needed a propane boiler to turn liquid to
gas.
I went with diesel :-)

How big is your propane tank?
In the cold temps you need a large tank that is mostly full to keep the
pressure high so it stays a vapor.
If the tank is small and/or below ~40% full then in the cold temps it
doesn’t stay a vapor and the engine won’t run.
This site has a good explanation:

Sean,
We have had a bear of a time getting out propane generator to start
below 10 degrees and defiantly below zero. What system are you using and does
it start in the cold? Everything I have found commercially available is setup
for a grid tie with a small heater on the carb that runs on grid power.
Thanks,
Brandon

In addition to froth-pak, be sure to tilt them at [latitude] + 23.5.
We are at 40 north so we tilt the panels at about 65*
40 + 23.5 = 63.5*
At that angle when there’s any amount of direct sunlight it slides
pretty quick.
But we also have a propane generator on-site because the stars don’t
always align just right :-/

I have a vague memory of a thread in bygone years about testing
different kinds of coatings to help with buildup of snow/ice but I can’t find
the thread and don’t remember if it was about solar panels or dish antennas.
The only thing I can find when I search my archive is about using
froth-pak on the back of the panels. Are there any other options that work?
