You can save a rendered image as a multi-layered EXR file which can contain the elements selected with the Render Layers feature.
You can render a black background by disabling the Render's Atmo/Cloud Visible checkbox, or even by unchecking the Render Atmosphere checkbox under the Planet.
I'll try and dig out more examples of this tomorrow, but in the meantime here are some links and examples that may be helpful:
I'm trying to render some clouds as a separate element so I can project them onto a dome in a Nuke set extension.
I already have a sky I'm happy with but I need some extra BG / MG / FG clouds/atmos.
Is there any way to have a final render which includes the clouds as layers or with an alpha I can premult? A black background could work as well if there is a way to disable the sky when rendering after the sun position is set.

No, I was using the alpha channel, but I grayed the map so the area not masked was gray, rather than pure white. It amounts to the same thing as you described, it's just more work. (The way I described it, that is.)
