Seems unlikely that we'll ever totally move away from combustion engines, simply due to sunk costs plus the advantages of energy density and quick refilling. I expect we'll see net-zero carbon emission gasoline and other hydrocarbons sold at the pump within the next few decades, produced with either solar or nuclear energy: https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_process https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_proces... https://www.youtube.com/watch?v=G8zOHZINyG8 https://www.youtube.com/watch?v=G8zOHZINyG8 Compressed natural gas (methane) is even easier to synthesize from the raw ingredients than gasoline or diesel fuels. It's used today in many city buses, fleet vehicles, and private cars in certain parts of the world: https://en.wikipedia.org/wiki/Sabatier_reaction https://en.wikipedia.org/wiki/Sabatier_reaction Such fuels could become less attractive if we invent lighter, cheaper, and much faster-charging batteries than the current state of the art, but I'm not holding my breath.
