If you are going to use them raw, maybe a vacuum sealer and storage in
the fridge, but there's no way to preserve them for an extended
period.

For cooking, I chop a 3 lb. bagfull all at once, put them in zipper
bags, flatten them out to remove the air, and freeze. You could divide
them into any amount, say four onions to a bag, then break off a chunk
at a time as needed.

You could always find a 1/2 of vertical space in the freezer to fit
them.

Don't bother to try them raw, they turn into rubber as soon as they're
frozen.
