A common approach to increasing the power from a combustion turbine when ambient temperatures are high is to cool the combustion air.  The cooler air is more dense, which increases the mass flow through the turbine.

Although inlet cooling produces benefits down to very low temperatures, the condensation that occurs when air is cooled below its dewpoint presents a practical limit.  Desiccants, which can dry air without first cooling the air below its dewpoint, can overcome this limitation.

AIL Research has demonstrated a three-stage gas-turbine inlet cooling system that delivered air at 17 F and 30% rh.  Although we are not now actively pursuing this concept, we would be very interested in talking to organizations interested in exploring very low-temperature inlet cooling.
