[font size=3]DENVER – A team of scientists from University of Colorado Denver has developed a novel energy system that increases the amount of energy harvested from microbial fuel cells (MFCs) by more than 70 times. The new approach also greatly improves energy efficiency. MFCs are emerging as a way to use bacteria to directly harvest electricity from biodegradable materials, such as wastewater or marine sediments.
The energy from a single MFC reactor is usually too low to be used in the real world. But CU Denver engineers developed a harvesting system to allow active extractions of electrons from bacteria.
“This process changes the way we think about MFC energy,” said Zhiyong (Jason) Ren, PhD, assistant professor of civil engineering in CU Denver’s College of Engineering and Applied Science. “This may be a game changer for waste treatment or remote sensing because we’ve proven we can harvest energy as well as generate savings.”
Data collected shows the system increased energy output by 76 times and improved energy efficiency by 21 times compared to a commonly used charge pump.
