Alice ends with share for gas charging (8)

I believe the answer is:

aeration

I'm a little stuck... Click here to teach me more about this clue!

'gas charging' is the definition.
I can't judge whether this defines the answer.

'alice ends with share' is the wordplay.
'ends' says to hollow out the word (remove centre letters).
'with' means one lot of letters go next to another.
'share' becomes 'ration' (ration is a kind of share).
'alice' with its middle removed is 'ae'.
'ae'+'ration'='AERATION'

'for' acts as a link.

Can you help me to learn more?

(Other definitions for aeration that I've seen before include "Mixing with air/gas" , "The process of adding carbon dioxide to liquid under pressure" .)

I've seen this clue in the Sydney Morning Herald.
