Abstract
The integration of hydrogen in the primary energy mix requires a major technological shift in virtually every energy-related application. This study has attempted to investigate the techno-economic solar photovoltaic (PV) integrated water electrolysis and waste incineration system. Three different strategies, i.e., (i) PV + Battery (Hybrid mode with required batteries); (ii) auto-ignition (Direct coupling); and (iii) PV + Secondary-Electrolyzer (Direct coupling assisted with secondary electrolyzer), have been envisioned. The `PV + Battery' consume 42.42 % and 15.07 % less energy than the auto-ignition and `PV + Secondary-Electrolyzer' methods. However, the capital cost of `PV + Battery' has been calculated to be 15.4 % and 11.8 % more than auto-ignition and `PV + Secondary-Electrolyzer, respectively.The energy consumption relative to waste input, the `PV + Battery' method used 80 % less energy, while auto-ignition and `PV + Secondary-Electrolyzer' showed 70.5 % and 77.5 % less energy, respectively. Furthermore, these approaches showed a vast difference in cost-benefit for the longer run. `PV + Battery' was forecasted to be 73.3 % and 23.3 % more expensive than auto-ignition and `PV + Secondary-Electrolyzer' methods, respectively, for 30 years. Overall, this study can benefit from using either of these methods depending on the application, usage scale, and climatic conditions.
