Water / methanol injection

I am hoping that John Farley will see this and respond.
I have been reading about water/meth injection in piston engines and I wonder whether it might be useful for very small gas turbines. Does anybody have experience or knowledge of this in aircraft engines.
Some of the claims and descriptions are puzzling me. Since methanol has a lower calorific value (LCV) than petrol, I cannot see how it could boost power. The water, however, would reduce air temperature, making it 'easier' to compress. On the other hand, if they are referring to nitromethane, this would have the effect of enriching the oxygen content.
So the question is, what is the chemical content of water / method used for gas turbines?
