It's been confirmed that there is no Nano catalyst. You upgrade modules by challenges, if I'm correct. For an example, you might have to kill enemies while armored to upgrade your armor modules. I think you unlock modules by challenges, too. Not sure.
We might see story-unlocked, challenge-upgraded modules that carry over to subsequent playthroughs (New Game Plus).
That would be pretty cool.
Upgrading modules through challenges, though, is indeed confirmed.
