Biorenewable Gaseous Fuels

Abstract

Main biorenewable gaseous fuels are biogas, landfill gas, gaseous fuels from pyrolysis and gasification of biomass, gaseous fuels from Fischer–Tropsch synthesis and biohydrogen. Biogas is a valuable biorenewable gaseous fuel that is produced in digesters filled with the feedstock like dung or sewage. Biogas can be obtained from several sources. The main constituents of landfill gas are methane and carbon dioxide, both of which are major contributors to global warming. As a sustainable energy source, hydrogen is a promising alternative to fossil fuels. It is a clean and environmentally friendly fuel. Hydrogen is the fuel of the future mainly due to its high conversion efficiency, recyclability, and non-polluting nature. Syngas can be produced by gasification of biorenewable feedstocks, also called biosyngas. Biosyngas can be converted into a large number of organic compounds that are useful as chemical feedstocks, fuels, and solvents.
