Abstract
An effective alternative energy source as a substitute for fossil-based fuels has become a major area of research for sustainable energy development. It is undeniable that there has been a decline in fossil fuel reserves as the primary energy which forces the development of new energy sources to meet requirements of both renewable and ecological aspects. In both of these aspects, hydrogen (H2) is one of the most promising renewable and environmentally friendly energy sources. Besides being able to be used to produce heat through combustion because it has a high calorific value (142 kJ/g), hydrogen can also be used to activate fuel cells to produce electrical energy without toxic gas emissions. Various applications of hydrogen gas led to the discovery of new sources and methods of producing hydrogen, including from the feedstock of greenhouse gases which has main component of CH4 and CO2. This review describes plasma dry reforming of greenhouse gas along with plasma decomposition of greenhouse components, namely CO2 and CH4 as an alternative process for hydrogen gas formation. Plasma-assisted decomposition of each compound, CO2 and CH4 from the view of plasma parameters and the effect of additional of catalyst are also discussed.
