Abstract
Nanotechnologies offer the possibilities to upgrade energy productivity and storage over all the fields of industry. The economically controled sustainable power source production through new technological arrangements and advanced production techniques are the current need. For the past few decades, all industries and every individual are consuming more amount of electrical energy. The demand on electrical energy is rapidly increasing every year. The storage of electrical energy is a challenging issue in energy sector. Current utilized batteries Amuthameena S.

are not that much reliable for long time storage. Implementing nanotechnology to the energy storage is the current interest of research. Supercapacitors, Li-ion batteries, and hydrogen storage are the most recent technologies in the energy sector. There are several ways to fabricate the electrodes for the energy storage devices. Nano-based components like light-emitting diode provide efficient usage of electrical energy. This chapter is proposed to review the past, current and future role of different nanomaterials in the energy sector. Keywords

Introduction In recent days, there is a need for enormous amount of energy for our survival [1, 2]. To meet this demand, the energy should be stored efficiently in various forms, so that it can be delivered whenever required [3, 4]. Fossil fuel resources are also getting limited due to the consumption of excess energy. These resources may be further diminished in future [5, 6]. Therefore, the society is moving toward renewable energy sources that are not exhausted anytime. In addition to the sustainable energy sources, efficient energy storage systems are also needed. Batteries are the primary energy storage devices. Secondary batteries, so-called rechargeable batteries, are particularly widely used these days. Also, other than batteries, various other devices for energy storage are available commercially [7, 8]. Electrical energy storage (EES) denotes to a progression of transforming electrical energy storage into a storable form so that it can be converted back to electrical energy whenever needed [9, 10]. Such a process is utilized at times of high generation cost, high demand, or when no other generation are available. EES finds application in portable devices, transport vehicles, etc. And also, they subsidiz
