Liquid nitrogen
The diatomic character of the N 2 molecule is retained after liquefaction.The weak van der Waals interaction between the N 2 molecules results in little interatomic attraction. This is the cause of nitrogen''s unusually low boiling point. [1]The temperature of liquid nitrogen can readily be reduced to its freezing point −210 °C (−346 °F; 63 K) by placing it in a vacuum chamber pumped by a
Liquid air energy storage (LAES)
Furthermore, the energy storage mechanism of these two technologies heavily relies on the area''s topography [10] pared to alternative energy storage technologies, LAES offers numerous notable benefits, including freedom from geographical and environmental constraints, a high energy storage density, and a quick response time [11].To be more precise,
