My friend and I were discussing about the paper he had presented in a college changed into a argument and I really want to know the correct answer so that we can enhance our knowledge.He said that he did his paper on the topic Hybrid vehicles (with CNG and motor) but when I said about the paper on Biogas he said that the processed, compressed and purified Biogas with high Methane content is CNG. Heated argument sparked between us till the lecturer comes.So I am throwing the same question to you CEans.

Which one has the better property to be adapted as fuel?

Is highly compressed, processed with high methane content Biogas same as CNG?

As CNG also had same similar composition,please help me…………
