Bioelectricity Harvesting at Aquaponics System: Current and Future Challenges

Bioelectricity is one of the high potential alternatives for sustainable energy production. Bioelectricity generated from living organisms including plants and bacteria has been discussed and explored by researchers in the past decades. Several methods of electrical energy harvesting had been researched and developed with living organisms as the sources of energy including plant microbial fuel cell (PMFC) and plant-based cell (PBC). It was recognized that electrical energy can be harvested from living organisms and has great potential. Aquaponics on the other hands is known as the combination food production system involving aquatic species, plants, and bacteria, where it has the elements needed for bioelectricity generation. This paper will review the potential of harvesting electrical energy from living organisms at the aquaponics system and recommendations for future works.
