MATERIAL FOR LOW-COST HYDROGEN GENERATION

Abstract

A viable option for storing green energy is hydrogen, which also can address a limited pressing energy related problem. Compared to natural gas, hydrogen burns at a significantly faster rate with a far lower initial energy requirement in the air. Hydrogen has an energy yield of 122 kJ/g, which is 2.75 times greater than that of conventional hydrocarbon fuels. One of the crucial factors, along with the amount of energy used and the emissions produced, is the production of hydrogen.

Currently, just 2% of the world's energy needs are met by hydrogen production. Numerous energy sources, including biomass and fossil fuels, the thermochemical process, electrolysis, solar hydrogen production, and biological products, can be used to manufacture hydrogen. High temperatures are used in thermochemical water splitting to extract hydrogen and oxygen from the water. A water molecule undergoes an electrochemical reaction in which it splits into hydrogen and oxygen gases.

Used stainless steel with a different KOH concentration of distilled water for the generation of hydrogen. Used different electrolytes with stainless steel of grade 316L to increase the efficiency of hydrogen generation and it is found that the interelectrode gap will increases then the hydrogen generation efficiency was decreased. The hydrogen generation rate was gradually increased with the applied voltage increase due to the formation of ion exchange on the stainless-steel electrode surface and the reaction kinetics accelerated.
