The performance and efficiency of novel oxy-hydrogen-argon gas power cycles for zero emission power generation

This study investigates the performance and efficiency of closed-loop oxy-hydrogen Brayton power cycles through numerical modelling simulation. Coupled with storage hydrogen oxygen produced by a water-electrolysis system, these have potential to produce flexible electrical at high thermal whilst producing zero exhaust gas emissions. The output are investigated using thermodynamic model. A standard Argon Power Cycle (APC) fuelled is explored which yields an 19% under typical operating conditions. To improve performance, cycle modified including intercooler, reheater regenerator, has increase 64% when same In addition, use helium air as working fluid explored, well methane cycle. It found that hydrogen–helium more efficient over all pressure ratios but most expensive operate.
