Carbon Nanotube Nanostructured Hybrid Materials Systems for Renewable Energy Applications

Abstract

Global energy demand is growing at an alarming and unsustainable rate, drawing mainly on the use of fossil fuels. These reserves are decreasing rapidly and becoming increasingly expensive. The associated emissions of greenhouse gases and other toxic pollutants are becoming environmentally unacceptable. Energy security has become a major issue as fossil fuels are confi ned to few areas in the world and their availability is controlled by political, economic, and ecological factors. A global coherent energy strategy that encompasses the entire energy life cycle is required in order to address all the forms of energy harvesting, storage, conversion, transmission, and distribution. Hybrid nanomaterial systems hold the key to fundamental advances in direct renewable energy and energy storage and conversion which are needed to enable renewable energy and meet the general energy challenges and associated environmental effects. This paper presents new approaches and methodologies used to design and develop carbon nanotube nanostructured hybrid nanomaterial systems incorporating structural and light-absorbing electron donor polymers, inorganic semiconductors, metallic and ceramic nanoparticles as energy harvesting and storage systems.
