Correction: Hydrogen Production from Biowaste: A Systematic Review of Conversion Technologies, Environmental Impacts, and Future Perspectives (Energies, (2025), 18, 17, (4520), 10.3390/en18174520)

In the original publication [1], “Gbiete, D.; Narra, S.; Mani Kongnine, D.; Narra, M.-M.; Nelles, M. Insights into Biohydrogen Production Through Dark Fermentation of Food Waste: Substrate Properties, Inocula, and Pretreatment Strategies. Energies 2024, 17, 6350. https://doi.org/10.3390/en17246350” was not cited. The citation has now been inserted in Section 3.1, paragraph number one, and should read: Thermochemical conversion technologies present promising avenues for sustainable hydrogen production from organic waste streams. They offer high efficiency and versatility. Recent research efforts by various scholars have contributed to advancing these technologies [35]. Figure 3 shows the general framework of thermochemical pathways for producing hydrogen from organic biomass. With this correction, the order of some references has been adjusted accordingly. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
