The course aims to educate students on the basic and creative concepts of energy technologies in the aspect of Nanotechnology. By covering the different areas of emerging technologies from fossil fuel conversion, ultraclean fuel production and utilisation, solar photovoltaic conversion to hydrogen and energy storage, the course prepares students for these revolutionary technologies. Understanding the fundamental concepts of these technologies allow students to be creative towards the development in these areas. Importantly, rather than focusing solely on ultimately renewable energy solutions, the course incorporates the complementary views on fossil but ultraclean fuel technologies, as well as their importance as intermediate energy solutions. Such knowledge shall equip students with holistic views on various energy solutions, with implications of assisting them in managing these technologies in their future professions.
