Are there logical gaps in the periodic table in which you could insert a new mystery element for use as a fuel?

As in the title.

We have the modern periodic table:

In a potential near (or far) future setting humanity discovers a new element which serves as the basis for a cleaner, higher energy density fuel than anything we have today.

How this element is found is irrelevant, I don't care if it came from a comet smashing into earth or was found on an exploratory space mission to some other place.

1. Are there potential gaps in the periodic table where such an element could exist?

2. Where on the periodic table would such an element land to be the best fuel source?

Criteria for "best"

• Higher energy density than Nuclear
• Cleaner than all fossil fuel types
• Preferably renewable.
