I'm trying to take all occurrences of # and if they are consecutive replace them with just one #.
e.g.
ab ### cde fghi## jklm
would become:
ab # cde, fghi# jklm
My initial goal was to replace all consecutive digits with # so; 120 -> # and 3->#. However I found that 120->###. So now I'm left with this new problem.

Using tr -s:
$ echo 'ab ### cde fghi## jklm' | tr -s '#'
ab # cde fghi# jklm
-sSqueeze multiple occurrences of the characters listed in the last operand (either string1 or string2) in the input into a single instance of the character.
This occurs after all deletion and translation is completed.
Your original problem could have been solved with:
sed -E 's/[0-9]+/#/g'
Or POSIXly:
sed 's/[[:digit:]]1,/#/g'
Or:
tr -s '[:digit:]' '[#*]'
