The LNG also takes up 3x the volume in shipping.

Also LNG in Europe is currently over $15/mmbtu, and 55% efficiency applies only to advanced (expensive) combined cycle plants that need to run 24/7 to achieve that rate. Peaker plants are less than half as efficient.

So instead of 25-30 times more energy/$ from solar, its closer to 35-50 times, before including the cost of the power plants that burn the fuel.
