本研究借由数值模拟，探讨闭环氢氧布雷顿动力循环之效能与效率。再加上水电解系统产生的储存氢和氧，这些循环有可能以高热效率产生灵活的电力，同时产生零废气排放。循环的效率和功率输出的研究使用的热力学模型。一个标准的氩动力循环（APC）的燃料由氢的探索，在典型的操作条件下，产生的效率为19%。为了提高性能，该循环通过包括中间冷却器、再热器和再生器来修改，当在相同条件下操作时，其具有将效率提高到64%的潜力。此外，氦气和空气作为工作流体的潜在用途进行了探索，以及甲烷燃料循环。据发现，氢氦循环是更有效的所有压力比，但最昂贵的操作。
This study investigates the performance and efficiency of closed-loop oxy-hydrogen Brayton power cycles through numerical modelling and simulation. Coupled with storage hydrogen and oxygen produced by a water-electrolysis system, these cycles have the potential to produce flexible electrical power at high thermal efficiency whilst producing zero exhaust gas emissions. The efficiency and power output of the cycles are investigated using a thermodynamic model. A standard Argon Power Cycle (APC) fuelled by hydrogen is explored which yields an efficiency of 19% under typical operating conditions. To improve the performance, the cycle is modified by including an intercooler, reheater and regenerator, which has the potential to increase the efficiency to 64% when operating under the same conditions. In addition, the potential use of helium and air as the working fluid is explored, as well as a methane fuelled cycle. It is found that the hydrogen–helium cycle is more efficient over all pressure ratios but the most expensive to operate.
