Bioenergy and Kappe Environmental Engineering Laboratories
The main focus of the Bioenergy and Kappe Environmental Engineering Laboritories is the development of new renewable energy technologies such as microbial fuel cells and thermal batteries for achieving an energy sustainable water infrastructure.
Bruce Logan and his collaborators have invented a method for sustainable hydrogen production using microbial electrolysis cells (MECs), a method for water desalination that does not require electrical energy from the grid or high pressures called microbial desalination cells, reactors to harness salinity gradient energy in micorobial reverse electrodialysis cells (MRCs), and improved direct bioelectricity generation by several orders of magnitude in microbial fuel cells (MFCs).
Recently, a new method of capturing waste heat was invented based on using waste heat to distill ammonia out of water, and to use ammonia to generate power in a flow battery. Other research in the laboratories include the exploration of how large aggregates form in the ocean, called marine snow, that can help to sequester carbon to deep sediments, and molecular and nanoscale techniques to study particle dynamics and microbial adhesion in engineered and natural systems microbial adhesion and transport.
Current research focuses in the lab include:
- Bioenergy production using exoelectrogenic microorganims
- Renewable energy production using waste heat and salinity gradient energy
- Environmental and chemical transport processes
- Biological wastewater treatment
