NRL has a broad portfolio of technologies and over 1300 active patents or patent applications that are available for license. Below is a list of links to more information for a number of NRL technologies that have potential commercial applications.


Miniature Microbial Fuel Cells

NRL has developed a novel microbial fuel cell (MFC) for harvesting energy from aerobic aqueous environments. It is powered by passive nutrient diffusion instead of energy-draining pumps used in other MFCs, thereby increasing the net energy output. The NRL design sequesters electrochemically active microbes in the cell, rather than relying on environmentally available bacteria. This allows the NRL MFC to be placed in a wide range of aerobic aqueous environments, not only in the bacteria's natural habitat at the sediment/water interface.

Zirconium-Aluminum-Hydride Nanoparticles

NRL has eliminated the formation of aluminum oxide coating, the impediment associated with burn kinetics for metal-Al Hydride nano-scale particles. NRL Investigators have developed a method for producing stabilized Zr-Al Hydride nano-scale particles with carbohydrate based gel coatings that are air stable.

Continuous Sustainable Power Supply: Benthic Microbial Fuel Cell

NRL has developed the benthic microbial fuel cell (BMFC) as a persistent power supply for marine-deployed applications. The BMFC operates on the bottom of marine environments where it oxidizes organic matter residing in sediment with oxygen in overlying water. The NRL BMFC is a maintenance free, non-depleting power supply suitable for a wide range of sensors presently powered by batteries.

High Performance Electrochemical Capacitors: Nanoscale Metal Oxide Coatings on 3D Carbon Nanoarchitectures

NRL has developed scalable, solution-based benchtop methods to generate conformal ultrathin (less than 20-nm thick) metal oxides on the high-surface-area walls of carbon nanofoam papers (0.1-0.3 mm thick). The resulting ultrathin oxides of manganese (Mn) or iron (Fe) rapidly take up and release electrons and ions, thereby storing energy at 300-600 Farads per gram of oxide (with typical oxide loadings of up to 50 wt. %), while the carbon nanofoam paper serves as a 3-dimensional current collector and defines a pre-selected porous electrode architecture.

Sputtered Thin Film Photovoltaics

NRL has developed a suite of processes for the fabrication of bulk and sputtered thin film copper indium gallium diselenide (CIGS) and related materials for photovoltaic (PV) applications. These processes result in films with better uniformity over large areas than existing techniques such as evaporation.
