Good Morning All!

Is there any productive use of Charcoal Ash (from a BBQ Grill) in the
garden.


No. There are chemical and other additives in charcoal that I'm sure you
wouldn't want leached into the soil. It's not safe even for the compost.

Even wood ash is not recommended unless you're looking to treat very
acidic soil.

Well, wood ashes are a good source of potassium but it has the problems
that you have listed above.
