Let's try a less crazy town model.
Assumptions:
- Renewables do not exist.
- Nuclear is on time and on budget.
- Seasonal driving variability is 20% with rare spikes of 100% for periods of a week or longer.
- Batteries will still be $200/kWh in 8 years.
- No efficiency improvements by switching to EV beyond moving the waste heat to the nuclear reactor.
- All oil is for cars
The total energy of oil that the US consumes is 1.5TW. It would provide 450GW of work in an ICE. With variability that's ~600GW
Each car needs 2kW of capacity.
Get all of your 2kW from AP-1000s at $6600/kW
Buy 1kW of electrolyser at $300/kW.
Buy 1kW of Gas Turbine at $1000/kW
Fuel the turbine with hydrogen stored in salt caverns or ammonia (or even fossil fuels) for the 2% of the time you need it.
This is $13k per car.
Spend $7200 on 36kWh of stationary batteries at the charging site. Now every car can charge a day's worth of power in a single 15 minute window. On the rare spikes during holidays, use your gas turbine to top them back up.
This costs less, is more resilient, is more convenient, and uses less carbon than your most optimistic all nuke scenario. Does it not?
