There will always be a place for the ICE.
But, it will be less prevalent for the average transport vehicle as this is the market EVs have a true advantage.
Hybridization of most other vehicles is logical for design reasons.
If an ICE is optimized as a constant load generator, you will be able to minimize fuel use and size. Material science as well as engine design will boost fuel efficiency past 50%.
And there is the pathway of hydrogen storage via carbon polymerization. This is why I am a supporter of renewable energy. It is reducing the cost of electricity dramatically in some regions. It cannot support a grid like nuclear can, but that cheap electricity can be made into a hydrocarbon. Stored electricity. The United States Navy already has an ongoing research project that takes CO2 from sea water and hydrogen from electrolyzed water to produce JP8 through heat, pressure and specific catalysts. However, most any hydrocarbon can be produced. A lower energy pathway would be to produce dimethyl ether. Stored in low pressure propane tanks, it can be used directly as a fuel or as a feedstock for chemical production.
Our future ICE hybrids will be nuclear/renewable powered.
