Feels like the death throes of the internal combustion engine, the supernova before they die out in common usage.
Or not.
Definitely not. Passenger cars will go EV relatively quickly, but you’re not going to see ICE go away in your lifetime.
Heavy duty trucks, aircraft, ships, etc all use petroleum combustion. That’s not going away any time soon. And as long as that’s still around they’ll still be making diesel.
You’ll end up seeing EV half ton and quarter ton pickups, potentially EV replacing the gas option in 2500+ trucks, but they’re going to have a diesel option for decades.
You're right, I should have specified "consumer ICE."
It’ll become rarer, but will never go away. As long as diesel is being made, heavier duty trucks will have a diesel option.
Even if it becomes a solely biodiesel option. You’re just not going to beat the efficiency, energy density, and quick refueling of an internal combustion engine until you can have a battery 1/15 the mass for the same energy, and can charge the thing in under half an hour, and doesn’t cost more than the vehicle itself when it’s time to replace it.
ICE engines, and diesels in particular can run for millions of miles. The record for a semi mileage is just over 3 million miles on the engine. You’re not going to find a battery pack that can go anywhere remotely close to that long. Especially in a heavy use vehicle like a truck that will be constantly going through charge cycles.
Just looking at the Tesla semi, the 500 mile range battery is 900kWh. A 100kWh model S battery costs $15,000 to replace, with $13,500 of that being the battery itself. Scaled up, the semi battery would be in the $90-100k range to replace.
The average semi runs around 100,000 miles per year. If you can get 1,000 full charge cycles out of the battery, you’d be replacing one every 5 years to the tune of nearly $100k each time. Not to mention replacing the electric motors themselves at several grand pop, and those don’t tend to last as long as the battery. Especially in a truck hauling 82,000lbs.
