Prospect for the production of Silicon as energy carrier from Rice Husk as renewable energy resource
Publication Date : 29/05/2020
Reserves of fossil energy are diminishing and total energy requirements however are intensely increasing. Their unsustainable nature from the point of view of future availability and environmental impact, has spurred an interest in diversification of energy sources, with particular interest in renewable energy. The solar energy industry is a player in the renewable energy segment, and the electricity generation from solar cells is considered to be one of the key technologies of the future. Silicon has a very broad spectrum of usage nowadays and it lies at the heart of much modern solar energy technology. Rice is one of the major crops grown through the world. Due to its high silicon content, rice husk (RH) has become a source for preparation of elementary silicon. Despite the fact that Si is the second most abundant element in the earth’s crust, processes to form it is usually complex, costly and energy intensive. Development of a simple low energy and sustainable production of Si from RH as biomass is desirable and welcome by many industrial applications. This study highlights the renewability of Si and combines a microwave heating method and acid digestion to determine it in rice husk ash RHA.
