Hydrogen, in 2016, is a non-starter. First you can't just 'get' it. We're quickly getting an EV grid and the Natural Gas 'grid' is already there.

Not sure what you mean here. We are "quickly getting an EV grid", but somehow "quickly getting a hydrogen grid" is such a huge problem? If Tesla can pull off the EV grid, then who's to say Nikola (or some other company, for that matter) can't do the same with hydrogen?

There's also the possibility for these trucks to be plug-in hybrids. They're not talking about it, but adding support for an external charge supply would be more or less trivial.

We definitely know the drive train can act as a "big engine brake". It uses regen braking, which as we know is very well establish technology. It's like compression brakes on steroids that charge the batteries and make no noise. In theory, the regen braking should provide stopping power very similar to acceleration power. The actual brakes should only need to be employed in emergency situations and at, and approaching full stop.

Why is the cost of energy going to rise? Solar will be so cheap in the nearish future that energy prices will drop. Already some places are seeing prices dip below zero at certain times due to over-production. Germany is now working on storing excess (zero-cost) grid energy in the form of hydrogen or ethanol to be burned later when prices recover. The energy becomes so cheap at times, that water electrolysis becomes an economical source of hydrogen. Prices behaved similarly in Chile this past summer; how long will it be before they start storing the excess as well? With the development of grid scale storage and ever cheaper solar panels, I think energy is going to become much cheaper.

Not to mention, automation of coal mines will only cause the price of coal-sourced energy to drop.

I suppose it is silly, but it's in response to another poster. This may be a great way to produce ethanol, but it's almost certainly a very bad way to produce room heat from wall electricity. If you think that's a "long list of conclusions" that are in some way questionable, then by all means, let's see the questions.

Resistance heating is very energy efficient (when measured at the point of use; there are plenty of losses in generation and transfer), it just usually isn't very cost efficient compared to other available options. However, using electricity to ultimately produce heat in the manor being discussed here will never be as energy OR cost efficient as resistance heating, unless it allows you to take advantage of a *significant* rate reduction.

As you mention, a heat pump would provide well beyond 100% (closer to 300%) effective efficiency in moderately cold weather.
