In view of increasing rates of waste generation, managing waste by converting it into energy is a promising solution. Hydrogen, a high-level energy fuel (122KJ/g), shows the most potential as it can be produced from biological wastes. In the anaerobic digestion process, a large amount of hydrogen is produced by various microbes (potentially 400L to 100L of H2/kg dry matter), which is rarely detectable in final product that is biogas. This hydrogen gas needs to be extracted by allowing proper separation of the phases of this process. The efficiency of this process can also be enhanced through improved reactor designs like the Anaerobic Hybrid reactor, Fixed Film reactor and Upflow Sludge Bed reactor. National initiatives like MNES and NMP will also help in making this technology available for large-scale use.
