But anyway, unless it's a full-EV, most likely the moisture extracted from the air by a conventional air-conditioning system could still be used for water injection in the engine.
In my navy days, the ship used a chill water system for air conditioning. You don't have room for ductwork and that would have compromised flooding and fire damage control. So you get water cold with traditional refrigeration, then pump it through pipes, and then through a radiator. Instead of hot water giving off heat inside the radiator, it's cold water inside absorbing heat. Leaks are also easily recovered and not as dangerous as freon is which was the comman refrigerant when the ship was built. Freon leaks would have found their way to the lowest part of the ship, the engine room, where any flame would turn it into deadly phosgene gas.
