I work for a major grocery chain. We own a lot of trucks. They roll 24/7. Drivers are scheduled around the clock. So even though these are generally short runs, refuel down time will slow down operations. This has a snowball effect in the warehouse which can get backed up when trucks are not available to move product out.
Is there diesel fuel at the warehouse?
We are nationwide, so I can only speak for my location. Yes.

These people never ceases to amaze me.

There is always a cloud in their silver lining and, if there's none, they'll get their hoses so they can make rain in somebody's parade.

Truckers and companies are lining up to reserve their semis.

And seriously, they don't think that these people and their analyst has not done their due diligence best use, cost-benefit... before they decided.

Come on!
Just curious how much money have they actually put down on those semis?

Also curious if they're all regional / local delivery fleets. Highly doubt OTR linehaul would buy them.

Think in bus terms:

City buses make excellent choice for EV; tons of them in Asia / Europe

Linehaul coaches (Greyhound, touring, etc.) make for a poor choice. I do not know of any EV tour coach / scheduled linehaul.

How much energy does an OTR semi use in electricity? Lets work it backwards and find out.

We know from science that a US gallon of diesel contains 40.7 kwh of electricity. We also know that a OTR gets around 5 miles to a gallon.

So a 500mwh battery contains a little over 12 gallons of diesel equivalent. Now, an electric motor is around twice as efficient as an ICE so that little over 12 gallons now becomes around 25 gallons of electricity equivalent.

So now your OTR diesel will have a 25 gallon fuel tank to drive from coast to coast. It gets worse. Your 25 gallon semi will not take less than a minute to fill up. It will take hours and maybe tens of hours to refuel.

And I don't want to hear anymore of this stupid "need a rest period BS." Most OTR trucking is a team driver deal now days. Those wheels are turning 16 to 18 hours/ day. And the times they are not turning the drivers are eating taking a shower or washing their cloths ect.

So 25 gallons of diesel in an OTR truck that gets 5mpg will go 125 miles. So your electric Semi will also go 125 miles. In reality it really won't. When pushed to extremes (like OTR trucks deal with every day) the electric motors start giving off a ton of heat and this will needs tons of cooling to deal with that. When you start dealing with heat issues, it will use a ton more power and suck up a ton more power from the batteries.

Here is a really good video that shows what we are dealing with.

Electric Semi Trucks as The Future of Trucking

Passenger vehicles get all the attention when any revolutionizing idea buzzes up the transportation industry.

But we often miss the fact that the U.S. freight industry consumes 2.8 million barrels of oil every day. That’s roughly equal to 1.02 billion barrels per year.

With America being one of the influential voices against climate change— they needed to show some environmental-grit against the smoke-guzzling semi-trucks and transportations.

Nevertheless, the logistic transport companies have taken it as a challenge and are undergoing a profound shift, as rapid as personal vehicles.

As many countries are looking to ban non-renewable-powered vehicles in the upcoming future, we need future-ready trucking systems that use electric solutions to speed up the long-haul freight management industry.

The desperate urge to have environmentally-friendly transport has ignited many veteran trucking manufacturers and start-ups to cater to the best electric semi-truck.

This will be known when the rubber hits the road.

Maybe do some actual research on how the other large EVs are doing instead of hacking the diesel specs to come up with an EV mile.

Another very real option is the Hyliion ERX, they have driving prototypes and over 200 firm orders. It’s batteries with a CNG generator.
1000 mi range, there are already 800 CNG fueling stations in US.
Some other points
Peterbuilt and Volvo are on board for the trucks all the equipment is installed on the line, Dana already makes the drive axles and Cummins is onboard for the engine and generator. Hyliion is doing the software, controls, batteries and cooling systems. They have history with all this as they have a hybrid mod for current trucks that’s been out for a few years.
The big point is that the battery pack is capable of 75 mi of range on battery alone so it qualifies for the full 40k credit same as Tesla.
They were an SPAC darling so they have 500 million in cash to finish the project.

Nice try...
A. Trucks can run 2-3 shifts on a full tank. Or more.
b. Most carriers are going to have fuel at the terminal. You're confusing warehouse with terminal or truck yard. Product gets stored/transferred through a warehouse. Trucks live at at a terminal when not on the road or at the warehouse.
3. What does it matter where the diesel is? Other than to make some inane argument about how a diesel truck may need to go "somewhere" to fuel.
