The problem is that solar only works when the sun is out and startup/shutdown on industrial chemical processes isn’t easy. Once you start involving batteries for around-the-clock operation, it’s more efficient just to use electricity directly. Synthetic hydrocarbons are best used for the cases like aviation where the energy density is the biggest hurdle.
