On top of that, the commenter is completely ignorant of the rise of saltwater batteries which don't even use lithium.
Also probably unaware that with the rise of extremely low cost, solar and wind, Fossil fuel use on the grid is economically nonviable long term.
Even so, the fossil fuels consumed on the grid are very likely to be combined cycle natural gas, which has less carbon emissions than have equivalent. Amounts of energy were burned in ice engines.
Also, The energy efficiency of electric vehicles is much higher than an ice car, so if solar and wind do not generate the electricity, it still will emit less carbon than an ice.
The only useful new engine technology I am interested in is an extremely compact recharging engine for use in plug-in hybrid electric vehicles. There was something about the inside out rotary engine a couple years ago but nothing has come off of it.

I'd not call the rise, yet. The Na ones' energy density (and specific energy) is even lower than Li based (LiFePO4 is lower than cobalt ones). They might be okay for grid storage, of course.
Saltwater batteries and lfp batteries don't require nearly as much active heating and safety measures as nmc chemistries.
So the pack level they become a lot more competitive. Rise of high density, salt, water and lfp. We should be able to produce 300 and 400 mile range sedans with sodium ion and LFP chemistries.
Just go look at the catl density numbers all the stuff they have going into production. Obviously has not scaled to the level it needs to. That's a big ramp up.
I believe the current numbers are 160 Watt hours per kilogram for sodium ion and a little over 200 for lfp. With cell to pack projections of 90%, while pack density of nmc is like 60-70% to the cooling and safety system requirements, sodium ion is a revolutionary development for the cheap EV.
The five year road maps for sodium ion gets it close to 200 watt hours per kilogram. Lfp should be reaching 250 Watt hours per kilogram in the next five years.
China specific. So not really mass market. Though I am glad to see that there are cars entering the market with sodium ion batteries. That does give me hope for the long term future of EV.
