Recent Developments in Microbial Electrolysis Cell-Based Biohydrogen Production Utilizing Wastewater as a Feedstock

Carbon constraints, as well the growing hazard of greenhouse gas emissions, have accelerated research into all possible renewable energy and fuel sources. Microbial electrolysis cells (MECs), a novel technology able to convert soluble organic matter such hydrogen gas, represent most recent breakthrough. While recovery from wastewater using microbial is fascinating carbon-neutral that still mostly limited lab-scale applications, much more work on improving function would be required expand their use in many these applications. The present limiting issues for effective scaling up manufacturing process include high costs cells, internal resistance methanogenesis, membrane/cathode biofouling. This paper examines evolution cell terms yield, operational aspects impact total output optimization studies, important information efficiency processes. Moreover, life-cycle assessment MEC comparison other technologies has been discussed. According results, at readiness level (TRL) 5, which means it ready industrial development, and, according techno-economics, may commercialized soon due its qualities.
