Green Technologies

Materials, Devices and Processes for Energy and Environmental Sustainability: The overarching theme of our research is to utilize materials-based solutions to the critical environmental and energy crises confronting us. Electrochemical Devices convert and utilize chemical and electrical energies at high efficiencies and are thus eminently suited for many applications resulting in reduced greenhouse gas emissions. Life and cost of these devices are principal barriers to their commercialization. Our research on such electrochemical devices include solid oxide fuel cells (SOFCs) for power generations, solid-oxide-membrane based electrolytic cells for converting waste to hydrogen and recycling hydrogen storage materials, solid-oxide-membrane based inert anodes for green syntheses of energy-intensive metals, and devices based on mixed-ion-electron-conducting oxide membranes for generating and separating pure hydrogen from hydrocarbons enabling effective CO2 sequestration.
