Biogas is a clean environment friendly fuel. Raw biogas contains about 55-65% methane (CH4), 30-45%
carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapours. Presently, it can be used only at
the place where it is produced. There is a great need to make biogas transportable. This can be done by compressing the
gas in cylinders which is possible only after removing its CO2, H2S and water vapour components. This paper reviews the
efforts made to improve the quality of biogas by scrubbing CO2 and the results obtained. There is a lot of potential if
biogas could be made viable as a transport vehicle fuel like CNG by compressing it and filling into cylinders after
scrubbing and drying.
