Because of the different possibilities to get combustion (example- sodium+water), a more-acurate bottleneck for a species would be "a chemistry & thermodynamics bottleneck". The ability to exploit temperature differences and local elements. And there are many ways to do it... plasma, burning, oxidizing, fusion\fission\compress things, infrared radiation, other radiation types, etc.
