India, Oct. 1 -- Blending 20 per cent compressed biogas (CBG) with compressed natural gas (CNG) could make the overall CNG fuel carbon neutral on a life cycle basis, according to a new study, which argues that India's transport transition will require different fuels and technologies for different vehicle segments rather than a single replacement for petrol and diesel.

The study, Study on Comparative Assessment of Vehicular Fuels in India's Energy Transition: A Multi-dimensional Approach by The Energy and Resources Institute (TERI), assesses petrol, diesel, CNG, electricity and liquefied natural gas (LNG) across two-wheelers, three-wheelers, private and commercial four-wheelers, light commercial vehicles (LCVs) and heavy-duty vehicles (H...
