Spreading of CNG Technology around Oceania

CNG is used in traditional gasoline internal combustion engine cars that have been converted into bi-fuel vehicles (gasoline/CNG). Natural gas vehicles are increasingly used in Europe and South America due to rising gasoline prices.

During the 1970s and 1980s, CNG was commonly used in New Zealand in the wake of the oil crises, but fell into decline after petrol prices receded. At the peak of natural gas use, 10 percent of New Zealand's cars were converted, around 110,000 vehicles.

Brisbane Transport and Transperth in Australia have both adopted a policy of only purchasing CNG buses in future. Transperth is purchasing 451 Mercedes-Benz OC500LE buses and is undertaking trials with articulated CNG buses from Scania, MAN, and Irisbus, while Brisbane Transport has purchased 216 Scania L94UB and 240 MAN 18.310 models as well as 30 MAN NG 313 articulated CNG buses. The State Transit Authority of New South Wales (operating under the name "Sydney Buses") operates 102 Scania L113CRB buses, two Mercedes-Benz O405 buses and 300 Mercedes-Benz O405NH buses and are now taking delivery of 255 Euro 5-compliant Mercedes-Benz OC500LEs.

In the 1990s Benders Busways of Geelong, Victoria trialled CNG buses for the Energy Research and Development Corporation.

Martin Ferguson, Ollie Clark, and Noel Childs featured on ABC 7.30 Report raising the issue of CNG as an overlooked transport fuel option in Australia, highlighting the large volumes of LNG currently being exported from the North West Shelf in light of the cost of importing crude oil to Australia. The opportunity and pathways to industry development are mapped out in summary on the Rosetta Moon news site.
