A one-stop guide to the future of sustainable energy production
The search for sustainable energy sources powered by renewable, non-fossil fuel resources is one of the great scientific challenges of the era. Microorganisms such as bacteria and algae have been shown to function as the basis of a microbial fuel cell, which can operate independently of an electrical power grid on the basis of renewable feed sources. These fuel cells have shown applications ranging from powering implantable biomedical devices to purifying rural water sources, and many more.
Microbial Electrochemical Technologies offers a one-stop shop for researchers and developers of technologies incorporating these microbial fuel cells. Beginning with the fundamental processes involved in microbial energy production and the key components of a bioelectrochemical system (BES), it then surveys the major BES types and crucial aspects of technological development and commercialization. The result is an indispensable introduction to these vital power sources and their myriad applications.
Microbial Electrochemical Technologies readers will also find:
- Detailed treatment of BES types including fuel cells, electrolysis and electrosynthesis cells, and more
- Discussion of commercialization aspects including modelling, performance analysis, and life cycle assessment
- An authorial team with decades of combined experience on three continents
Microbial Electrochemical Technologies is a useful reference for electrochemists, microbiologists, biotechnologists, and bioengineers.
