Abstract
Global warming is the major consequence of pollution. The pollutants that contribute to global warming are commonly known as greenhouse gases. The world has seen an increase in the carbon dioxide concentration over the past few years. The largest sources of carbon emission is the combustion of fossil fuels. The concept of “Green Clean Energy” raised on a mission to reduce the release of these hazardous emissions. Hydrogen is one of those clean energy fuel which helps in solving the present crisis. Materials such as chicken feathers can be used as a medium to store hydrogen. Several research studies are reviewed where chicken feathers are thermally treated by the method of pyrolysis to make them a novel material for hydrogen storage. The uniqueness in the structure and properties of chicken feather is it contains 90% of keratin fibre when heated increases its micropore volume that results in higher hydrogen uptake.
Highlights
The requirement for energy is rising exponentially day by day, but there is no sufficient conventional source of energy that can support this demand
A major greenhouse gas concentration in the atmosphere has steadily increased to 405.25 ppm in 2016 [2], making 2016, one of the hottest year ever recorded is shown in Figure1 [2, 3]
Hydrogen can be stored in numerous ways like compression, liquefaction, physio sorption in microporous carbon, metallic hydride and complex hydrides [7]
Summary
The requirement for energy is rising exponentially day by day, but there is no sufficient conventional source of energy that can support this demand. One of the prominent methods in physio sorption is usage of chicken feathers as carbon source This material is highly porous and has high surface area which contributes to higher physio sorption [8]. Slow pyrolysis is one of the heat treatments well known and commonly used to obtain carbon in a controlled monitored environment, time, and temperature. During this process volatile components from carbonaceous material are released. The six samples were pyrolysed in a two-step process, Firstly, heated at a low temperature at 215oC or 220oC for a desired time and a constant rate (3oC/min). The graph generated from the available data of residue fraction is shown in the Figure 6
