Solid state batteries are overhyped because their production complexity makes them a pricing nightmare for the average consumer. Sodium ion batteries are the practical choice for short distance transport because they are affordable and charge incredibly fast.

When it comes to long distance shipping or aviation, the energy density of liquid fuel is simply too hard to beat. Fossil fuels will stay dominant for decades, likely evolving into carbon captured or bio derived alternatives rather than being replaced by batteries.
