Hyphenation: Should it be context dependence or context-dependence?

This question is about hyphens in nouns. Grammarly suggests context-dependence, whereas I’m used to writing context dependence. I used to write the adjective as context-dependent but the noun without hyphen. Now I’m unsure, thanks to Grammarly’s insistence. This is for a contribution to a Springer volume with presumably more US than UK authors. I’m a non-native speaker.

Which one would you recommend and why?

(Side note: What about dependency versus dependence? I used to write dependency but it started to sound kind of stilted to me and so I switched.)
