In order for any alternative to gasoline or diesel to be viable as a transportation fuel, readily available refueling infrastructure is a necessary component of the ecosystem. However, the report does say natural gas (NG) has proven to be one of the most popular alternatives to traditional liquid fuels in many global markets, with compressed natural gas (CNG) being far more common than liquefied natural gas (LNG). Interestingly, the report says more than 80% of new NG refueling stations are expected to be CNG facilities in order to support light-duty NGVs, which are projected to account for 90% of the global NGV fleet at the end of the forecast period.
