Which EV would you get?

It's already working in buses.
I ran an LPG van, the donut tanks work, but I realise your methane tank might be ugly, and it's positioning in a car is problematic.
I spose it depends what you value most.

Show me a clean long-life battery and I'll show you a slavish-labour mining industry.

The materials used in batteries are also used in many other everyday items.
"Clean" they may not be (though not as "dirty" as some like to claim), but short-life they certainly aren't.

It's far worse than LPG as it cannot be liquified at room temp without very high pressures that would mean far heavier tanks. LPG can be stored in tanks at pressures of the order of bicycle tyres, but LNG needs cryogenic cooling for the same pressures to be viable.

It's not remotely a solution for private cars.

Fiat had a 1990s methane Seicento. I'll try to look it up -
edit - maybe I was thinking of the Elettra.

Methane-Powered Vehicles | NASA Spinoff​

Liquid methane is beginning to become an energy alternative to expensive oil as a power source for automotive vehicles. Methane is the principal component of natural gas, costs less than half as much as gasoline, and its emissions are a lot cleaner than from gasoline or diesel engines. Beech Aircraft Corporation's Boulder Division has designed and is producing a system for converting cars and ...

Gemini offers:
Sodium-ion battery manufacture primarily uses organic carbonate and ether-based solvents to dissolve conductive salts for the liquid electrolyte. [1, 2]

Common Solvents

• • Ethylene Carbonate (EC): A cyclic carbonate frequently used to help form a stable solid electrolyte interphase (SEI) layer on electrodes. [1, 2]
  • Propylene Carbonate (PC): A common cyclic carbonate with a wide liquid temperature range that remains stable at low temperatures, unlike in lithium-ion setups. [1, 2]
  • Dimethyl Carbonate (DMC): A linear carbonate added to reduce overall mixture viscosity and improve ionic conductivity. [1]
  • Diethyl Carbonate (DEC) & Ethyl Methyl Carbonate (EMC): Linear carbonates blended with cyclic carbonates to optimize fluidity and transport properties. [1, 2]
  • Ethers (e.g., Dimethoxyethane / DME, Glymes): Alternative solvents sometimes utilized for specialized or non-flammable ether-based sodium chemistries. [1, 2]

Thanks!

You know that the Topolino and the Ami are the same car wearing different pyjamas right? It's a great vehicle if you don't need to go over 28mph, don't need to take more than one passenger and don't need much luggage space.

Fine, that's what I suspected
