Hydrogen is rich source of energy but its properties in gaseous state cannot be used efficiently but at the liquid state in can be used in various application but high cost of liquefaction of hydrogen cryogenic system and less efficiency component turned the cryogenic science toward optimization. Second law efficiency analysis system components on demand base parameters, reduces cost of whole system. A mathematical computational program is made on the basis of hydrogen system and second law analysis is done on different input parameters is studied. Second law efficiency of hydrogen system is 19.82 % and COP is 0.9746 is found when inputs are at ambient condition and compressor pressure at 15 bar is provided, but study of graph shows that both start decreasing with further increases of compressor pressure whereas liquefaction mass ratio and Total work done is increases with increase in compressor pressure.
