They have considerably less energy density yes, but that was also the case for LFP batteries in the past.
LFP batteries have improved now though over the years and can now go quite reasonable distances, making the more expensive higher energy density batteries like NCM only needed for the longer range or performance variants.
The same should happen to the sodium based batteries, and LFP will eventually get to the point of the longer range types in the future.
Eventually, the range of the higher density types won’t be needed, and they’ll simply start including fewer cells of them to get the sweet point range which will then bring their costs / weight down when compared to lower density types, but it’s possible by that point maybe the lower density types simply dominate due to their general lesser cost?
All of this of course assuming something like solid state batteries don’t have their breakthrough low cost long lifespan moment.
