“…9) (Eq. 10) MEC are also considered to be used as a platform for energy-efficient waste water treatment (Sim et al, 2018). Various studies shows that bacteria which transfers electron to cathode belong to Pseudomonas and Shewanella species (Liu et al, 2008).…”

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.

“…11 Likewise, H 2 O 2 conversion efficiency was relatively lower when using actual wastewater, indicating significant losses of H 2 O 2 in the catholyte. 10 Review of the literature indicates that the scaling up of MEC for only H 2 O 2 production is still challenging, 44 but can be feasible for use of H 2 O 2 in situ in advanced treatment process. Much work is still needed for further improvement in the electrode materials that play a significant role in the ORR pathways and system performance.…”

“…who developed a 110-L dual-chamber up-scaled MEC reactor (10 L of cathode chamber and 1.6–2.0 V voltage input) to synthesize H 2 O 2 . Nevertheless, the H 2 O 2 titer was less than 100 mg L −1 after 20 days of operation, and the corresponding H 2 O 2 conversion efficiency was only about 7.2% in a form of short communication ( Sim et al., 2018 ). Thus, more efforts are required toward the scaling-up of the MES-based H 2 O 2 production.…”
