I wonder how hyped carbon nanotube technology is. In case of graphene, lots of groups had wonderful results on the theory, on simulations but when it comes to nanofabrication or mass-scale production no much progress is done.

It is like saying that nuclear fusion is wonderful in theory but not so much in practice, while we know that the biggest energy source of our galaxy is coming from a thing that uses fusion to generate its energy. We are at the beginning of the technical era, that first needs to revolutionise energy production and storage that will be required for space travel. I have high hopes in graphene and carbon nanotube tech.

> biggest energy source of our galaxy

You meant the Sun, of course. However, your phrasing sent me on a quest to answer the galactic question. From the following article, I learned that the "supermassive black hole at the centre of the Milky Way" emits "cosmic radiation at petaelectronvolt energies", which fits the bill for largest energy source of our galaxy.

On the other hand if your looking at energy by type, fusion wins hands down.
