coal is a solid but brittle
Coal vs. Solid fuel : factorio
Solid fuel can be a by-product from advanced oil refining/cracking, as it is a means to ensure that nothing backs up. You can always feed in any excess solid fuel into burner belts along with wood etc. When you get into Coal Liquefaction it is possible to gain energy from coal when transforming it to solid fuel.

brittleness
Quasicrystals are exceptionally brittle. They have few dislocations, and those present have low mobility. Since metals bend by creating and moving dislocations, the near absence of dislocation motion causes brittleness. On the positive side, the difficulty of moving dislocations makes quasicrystals extremely hard. They strongly resist deformation.
