Natural gas as a transportation fuel will grow, but slowly.

摘要

According to projections from the International Energy Agency (IEA), natural gas's transport fuels share is set to increase from 1.4% in 2010 to just 2.5% in 2018, with the necessity of infrastructure installation slowing its rise despite the fact that the US shale boom has natural gas selling at approximately 25% the cost of crude oil in that country. According to the IEA, although the next few years may see significant natural gas infrastructure begin to come online, "While this infrastructure development could eventually pave the way for substantial displacement of oil by natural gas in the transport sector, truly meaningful fuel switching is not expected to occur until after the end of the forecast period." Meanwhile, oil's transportation sector share is likely to decline slightly from 97.8% in 2010 to 96.4% in 2018.
