Q. Consider the following statements:
1.Compressed Biogas (CBG) has methane content of more than 90%.
2.CBG Blending Obligation (CBO) is a roadmap for mandatory blending of compressed biogas (CBG) in the transportation and domestic segments of the city gas distribution (CGD) sector in a phased manner.
3.When CBG is released into the atmosphere, it contributes to the oxygen content by releasing a portion of oxygen into the environment.
Which of the statements given above are correct?
Explanation –
Statements 1 and 2 are correct. Bio-gas is produced naturally (through a process of anaerobic decomposition) from waste/biomass sources like agriculture residue, cattle dung, municipal solid waste, etc. After purification, it is compressed and called as Compressed Bio Gas (CBG). CBG has methane content of more than 90% which is similar to commercially available natural gas in composition and energy potential. It can help reduce carbon emissions and provide additional revenue source for farmers. It can also help reduce import of natural gas and crude oil, ensuring energy security.
The CBG Blending Obligation (CBO) is an initiative by the Indian government to mandate the blending of CBG with natural gas in the city gas distribution (CGD) sector. This blending obligation is being implemented in a phased manner, with the target of achieving 5% blending by 2028-29.
Statement 3 is incorrect. CBG is primarily composed of methane (CH4), and it does not contain oxygen. Upon combustion, CBG produces carbon dioxide (CO2) and water vapor (H2O), but no oxygen is released into the atmosphere.
