The International Energy Agency weighed in last week as bullish on the future of natural gas as a transportation fuel.
According to the Wall Street Journal, the IEA “expects natural gas use in road and maritime transportation to rise to 98 billion cubic meters by 2018, covering around 10 percent of incremental energy needs in the transport sector.”
Three factors are behind this increase in the use of natural gas for transportation, according to Maria van der Hoeven, the IEA’s executive director. These are the fuel’s “abundant supplies as well as concerns about oil dependency and air pollution.” The cost factor is particularly a driver for commercial fleet operators where current fuel prices have become more favorable for natural gas over diesel.
In the U.S., all new trucks fueled by diesel or natural gas must meet the same standards for emissions of particulate matter and nitrogen oxides. Natural gas engines for medium- and heavy-duty trucks have surpassed U.S. Environmental Protection Agency’s stringent standards for particulate matter emissions by as much as 80 percent and for nitrogen oxides by up to 35 percent. Cummins Westport, the leading producer of natural gas engines, is investigating the feasibility of reducing NOx emissions from its spark-ignited natural gas engines to levels significantly below the current federal emissions standard.
Natural gas trucks have the potential to deliver tangible greenhouse gas emissions benefits over their petroleum-based counterparts. This certainty that natural gas vehicles are able to consistently deliver on their potential climate benefits in part depends on minimizing methane leaks caused by vehicle operations, refueling and maintenance.
