Isn't the intermittency of the energy source the issue? And there's currently no scalable solution to efficiently store excess energy generated from solar panels?

It's rather amazing that you think that people haven't already thought of this issue and addressed it.

In fact, it's long been addressed, and the cost of dealing with intermittency of renewable sources appears acceptable.

> Even former critics must admit that adding e-fuels through PtX makes 100% RE possible at costs similar to fossil fuels. These critics are still questioning whether 100% RE is the cheapest solution but no longer claim it would be unfeasible or prohibitively expensive.

Sure, that's why no one proposes only solar, nor do they propose solar in only one place at a time.

Intermittency means you need storage too. So, you build out storage too. The observation is vacuous.

A renewable grid includes storage. Storage is cheap and getting cheaper.
