Optimization of solar integrated electrolyser system for hydrogen production using Taguchi method

The age of modernization comes with its own set of flaws, which has to be mitigated as sooner as possible for a sustainable future. It is a well-established fact that the need for energy in this age of technology is at stake due to the incessant use of carbon based fossil fuels. Fossil fuels in themselves are not enough. They are very much likely to be exhausted sooner than expected. Therefore, a new clean and renewable alternative has to be adopted which could be able to meet the energy demand. Hydrogen Energy may be one of the most viable and suitable alternative ways to mitigate the energy demand, without affecting the environment. The project work is focused on the optimization of the key operating parameters of the electrolyser coupled with a solar photovoltaic (PV) system for hydrogen production using the Taguchi technique. In this work ten operating parameters have been selected using an L₂₇ (3¹⁰) orthogonal array for optimization. Based on the 27 orthogonal arrays, it was found that the maximum hydrogen production is 319.35 Ncm³/hr. After applying the Taguchi technique, found that the maximum hydrogen production was 645.89 Ncm³/hr., which gives 50.56% increment as compared to the highest value of production obtained from orthogonal array.
