Morphology
The phrase uses 'steam' metaphorically to mean one’s own power or energy rather than literal vapor, so a B1 learner who knows the individual words may not reliably infer the non-literal sense without prior exposure. However, components like 'under' + 'own' signal doing something by oneself, giving a clear clue to the general idea of acting without help, so the expression is only partially transparent.
Etymology
The idiom under one's own steam comes from the time of steam engines: when a train or ship moved by its own steam, it used its own engine instead of being towed. So now it means 'without help' or 'by your own effort'.
