A review on the impact of various factors on biohydrogen production

Biohydrogen generation from various waste materials is quite promising in renewable energy exploration. Biohydrogen is a cost-effective biofuel that produces both water vapor and energy when burned. However, biohydrogen production is more appreciable in utilizing various waste materials, thereby compromising both socioeconomic and technical strategies of energy exploration. The substrate, inoculum employed and their concentrations, culture kinds, and pretreatment procedure have all been found to be important in biohydrogen production. Physiological variables such as pH, temperature, redox potential, and partial pressure also significantly impact biohydrogen generation. The utilization of several growth factors, mainly the substrate, nitrogen, and phosphorus, also confronts extensive applications during biohydrogen production. This present study explores the enhancing activity engaged by the parameters and focuses on the inhibitory effects of the operating conditions.(c) 2022 Hydrogen Energy Publications LLC.
