Other Alternative Energy

Besides the well-known alternative energy categories such as wind/solar energy and biofuels/biodiesel, alternative energy also includes chemically stored electricity in batteries, capacitors, and fuel cells that could be made with some or all renewable materials. Researchers at ISTC have worked on batteries and supercapacitors for energy storage using renewable or waste materials. For additional information on renewable energy, visit the United States Environmental Protection Agency's page on Renewable Energy.

One of ISTC's previous projects was using biochar (pyrolized biomass) as the carbon source for the electrodes in supercapacitors. The top two diagrams show a schematic of a (a) biochar mini-chunk and (c) thin-film supercapacitor, and the bottom photos show low-resolution scanning electron microscope images of a (b) biochar mini-chunk and (d) thin-film electrode.
