ABSTRACT:
Energy storage efficiency is calculated for the solar thermochenical energy transfer system based on ammonia/hydrogen-nitrogen. The calculation for this system involves generation of thermodynamic data not available in the literature by a method in which use is made of the available phase

equilibrium measurements together with application of the criterion that the correct value of separation work for a two-phase mixture must be generated internally by degradation of mixing heat. Energy storage efficiencies for ammonia/ hydrogen-nitrogen are derived from the generated thermodynamic data and are shown to increase towards unity as the endothermic reaction approaches completion, 0.90 being obtained for reaction validity of the analysis has with efficiencies greater than extents exceeding 0.60. The been tested successfully by comparison between the thermodynamic predictions and experimental data in the form of measurements of the waste heat rejected from a counterflow heat exchanger operated with liquid ammonia feed and ammonia/hydrogen-nitrogen output.
