)
. Installation of such plants aimed at production
of Compressed Biogas (CBG) of the quality of Compressed Natural Gas (CNG) to
be used as vehicle fuel in addition to meet stationary and motive power, cooling,
refrigeration and electricity generation needs in a decentralised manner through
establishment of a sustainable business model in this sector. The purifi ed biogas,
compressed at 200 bar pressure and fi lled into CNG cylinders for various applica-
tions, should be in accordance with the approval given by Petroleum Explosive and
Safety Organisation (PESO) India (Annual Report, PESO
2011
). A compressed bio-
gas project is eligible to obtain Carbon Emissions Reduction certifi cates for meth-
ane avoidance and replacing fossil fuels (compression and utilisation of methane
gas vehicle fuel). Standards for biogas composition have also been developed, and
are being processed through Bureau of Indian Standards (BIS) (Figs.
