This seems like marketing nonsense to me... Carnot efficiency of a gas turbine is a function of the temperature the CT blade can sustain and the ambient temperature. (1-Tc/Th). So unless they've somehow had a massive breakthrough in material science they'll be as limited as all other gas turbine OEMs.

Air blast chillers are common in this power category so water usage isn't very high.

More importantly gas turbine power figures are quoted at an ISO 15C. So if you require 42MW at 40C ambient you'll buy an overrated engine to maintain your output. They've written this as a gotcha that their engine is more powerful than a less powerful engine. Well yeah...
