On January 3, 2025, a groundbreaking project led by researchers at the University of Maryland (UMD) seeks to transform ocean monitoring through the development of a novel bioinspired energy system. The Persistent Oceanographic Device Power (PODPower) aims to replace traditional lithium-ion batteries and underwater cables with a sustainable energy source derived from marine microorganisms.
The PODPower system utilizes a fermentation chamber to harness ocean microbes and organic materials, converting them into electricity. This innovative approach is expected to provide a continuous power output of 10 watts for over a year, significantly enhancing the capabilities of marine sensing technologies while minimizing environmental impact.
Key features of the design include a collection net inspired by fish gills, an auger for transporting organic matter, and a dual cathode system to optimize energy generation. These advancements address the limitations of previous microbial fuel cell technologies.
Funded by DARPA's BioLogical Undersea Energy (BLUE) program, the project has received $7.8 million for its initial phase, with potential additional funding of $3.4 million for further development aimed at achieving a power output of 100 watts and broader deployment in various marine environments.
The collaboration involves multiple prestigious institutions, including Battelle, George Washington University, Harvard University, and Johns Hopkins University, among others.
