Currently, there is greater emphasis on using renewable energy sources as compared to conventional sources of energy. Biohydrogen, a renewable energy source, serves as a promising alternative to fossil fuel‐based energy sources. The demand for sustainability is met by producing biohydrogen with the use of wastewater as a substrate. This review article focuses on different ways of biohydrogen production from wastewater with the help of microorganisms, such as light independent processes like dark fermentation and light dependent processes like photo‐fermentation, bio‐photolysis (direct and indirect) and integrated processes like sequential fermentation and combined fermentation. The biochemical pathways, microorganisms employed, specific pretreatment techniques, and efficiency of the biohydrogen production methods by H2 yield and H2 production rate from different wastewater sources are also discussed. Different methods like dark fermentation, photo‐fermentation and integration of these types using various substrates have been put forth. This review article also explains the various pretreatment methods of wastewater like physical, chemical, biological, and mechanical which is essential when using wastewater as substrate in order to increase biohydrogen production. The important characteristics that can influence hydrogen production, such as pH, temperature, hydraulic retention rate, and organic loading rate are also mentioned. In addition, the advantage and drawbacks of biohydrogen production, as well as the potential advancements presently being investigated to tackle these challenges are also highlighted. Therefore, many techniques and technologies are currently adopted to enhance the production of biohydrogen, which will lead to a sustainable environment.

“…Biohydrogen, as a fuel, has been seen as one of the cleanest energy carriers as it is renewable, carbon free, and has no emission of GHGs from combustion ( Abdin et al, 2020 ). Usually, conversion of lignocellulosic biomass to hydrogen can be accomplished by thermochemical methods (gasification or pyrolysis) and the biological process (bio-photolysis, photo fermentation, or dark fermentation) ( Singh et al, 2021 ). Apart from these routes, nanotechnology has begun to gain interest for promoting the biohydrogen production.…”

For decades, lignocellulosic biomass has been introduced to the public as the most important raw material for the environmentally and economically sustainable production of high-valued bioproducts by microorganisms. However, due to the strong recalcitrant structure, the lignocellulosic materials have major limitations to obtain fermentable sugars for transformation into value-added products, e.g., bioethanol, biobutanol, biohydrogen, etc. In this review, we analyzed the recent trends in bioenergy production from pretreated lignocellulose, with special attention to the new strategies for overcoming pretreatment barriers. In addition, persistent challenges in developing for low-cost advanced processing technologies are also pointed out, illustrating new approaches to addressing the global energy crisis and climate change caused by the use of fossil fuels. The insights given in this study will enable a better understanding of current processes and facilitate further development on lignocellulosic bioenergy production.

“…Research in various sectors is going on like different substrates are currently being tested for their H 2 producing efficiency. Research on Biomass from different sources is going on to check for a better renewable source, like using industrial waste water (Usman et al, 2019), lignocellulosic waste (Singh et al, 2021), food waste (Kuang et al, 2020), kitchen waste (Srivastava et al, 2021) and using different methods for hydrogen production using these biomasses. Wastewater from an industry rich in organic matter is also used to produce H 2 gas.…”

As the energy demand is continuously rising with the increase in population, the use of fossil fuels is also increasing at the same rate. These fossil fuels release greenhouse gases (GHG) which are harmful to human health and our environmental health and these fuels are also expected to exhaust in the near future. This eventually has led to an emerging need to shift to a more reliable, sustainable, clean energy source. Biohydrogen as fuel is a potential alternative, as hydrogen has proved to be one such fuel which has the potential to replace fossil fuels. There is a need to produce it in a clean, sustainable way to compete with the fuels that are being used currently. The hydrogen which is produced biologically is known as biohydrogen. Microorganisms also play a huge role in the process of hydrogen generation by virtue of their natural mechanism. Hydrogen can be produced biologically using approaches like biophotolysis (direct and indirect), fermentation (dark and photo) and microbial electrolysis cell (MEC). Among all, dark fermentation seems to be the most efficient when compared to other procedures. The challenges currently being faced with this technology are the yield of hydrogen, the high cost of the reactor and system efficiency. This technology still needs a lot of research and improvement to replace fossil fuels entirely.
