The International Energy Agency (IEA) has released a special report that highlights a very bright future for natural gas. The agency's report is entitled Are we entering a golden age of gas? The report considers the role natural gas has to play in light of improved near-term and longer term supply, challenging issues faced by mainstream fuels, the strength of the post-crisis natural gas market, and the role natural gas could play in facilitating a low-carbon energy economy and in improving local air quality.
Natural gas fuel for transportation is incorporated for the first time into various policy assumptions and scenarios considered.
The report states that CNG vehicles may emit less CO2 per km than electric vehicles (EV) and plug-in hybrid vehicles (PHEV), depending on the fuels used to produce electricity.
'In 2020, CNG cars are expected to emit less CO2 per km than PHEVs in all regions shown in Figure 3.7, assuming 10% of the vehicle-kilometres of PHEVs is electrically driven,' the report says.
