IIRC, a cascade of turbines, going from high-temperature water steam to basically room-temperature ammonia, can reach a total efficiency exceeding 50%.
Of course, ammonia is chemically active, and water at 700K is also chemically active, so the turbines, as usual, require special metallurgy and regular maintenance.
