The Kerala State Road Transport Corporation (KSRTC) is contemplating a detailed study into the feasibility of using compressed natural gas (CNG) as a cheap alternative fuel to run its buses in view of hike in price of high speed diesel.

The exhaustive study is being planned as the KSRTC management is still sceptical about the Rs.100 crore CNG plant proposed by the Union Petroleum ministry for Kochi to overcome the crisis of having to pay market rates for HSD.
