With the success of the country's first Natural Gas Vehicle, the Department of Energy and the Philippine National Oil Company are committing to convert additional diesel vehicles to run on compressed natural gas.

Former Energy Secretary Vincente S. Perez, Jr. created a Natural Gas Vehicle Program Office (NGVPO) to spearhead various efforts in the development and utilization of natural gas vehicles. The NGVPO took the lead in the implementation of the conversion of the DOE and PNOC-EDC shuttle services. The DOE's shuttle bus and Nissan Patrol were converted to run on dedicated natural gas. The PNOC-EDC shuttle bus, on the other hand, was converted to dual-fuelling, i.e. utilizing a mixture of natural gas and diesel. Gas supply will come from PNOC-Exploration Corporation's CNG refueling station in Echague, Isabela.

Conversion of PNOC-EDC's shuttle bus had been completed and was inaugurated by President Gloria Macapagal-Arroyo during the National Energy Week 2001 celebration on last December 3, 2001. Two other vehicles were also converted.
