Report Finds More Natural Gas Vehicles Would Not Raise Natural Gas Prices
A new study from the American Clean Skies Foundation (ACSF) finds that a transition to natural gas-fueled heavy- and light-duty vehicles over the next decade will have a minimal impact on natural gas prices.
The report, “Driving on Natural Gas: Fuel Price and Demand Scenarios for Natural Gas Vehicles to 2025,” used three scenarios to calculate potential natural gas demand and price impacts attributable to natural gas vehicles (NGVs).
“We found that the estimated level of natural gas demand from NGVs, even under the most optimistic scenario, accounted for only about 2 percent of the overall market by 2025,” said Gregory Staple, ACSF’s CEO and co-author of the report. “And the incremental rise in fuel prices for this high growth scenario was only approximately 25 cents per MMBtu, or 5 percent.”
“That’s largely because we expect the growth in natural gas vehicles over the next decade to provide adequate time for supply and infrastructure developments to keep pace with demand, and thus to moderate any incremental natural gas price impact,” Staple added.
ACSF’s optimistic growth scenario included high adoption rates of both light- and heavy-duty NGVs. In this scenario, the transportation sector’s natural gas demand grew from 57 billion cubic feet (Bcf) in 2013 to 711 Bcf in 2025, which equates to roughly 2.3 percent of total demand that year. The scenario estimated roughly 2.4 million NGVs on the road by 2025, of which 480,000 are heavy duty trucks. The effect on 2025 natural gas prices across the scenarios ranged from an additional 3 cents to 27 cents per MMBtu.
The report highlights the opportunity to diversify America’s transportation sector away from petroleum-based fuels. In the report’s highest NGV growth scenario, more than 180 million barrels of petroleum fuels are displaced by natural gas in 2025 and almost 1 billion barrels of oil consumption avoided cumulatively from 2013-2025.
Report co-author Patrick Bean said, “Our analysis should give businesses, consumers, regulators and political leaders confidence that a plausible transition to NGVs can achieve energy security objectives while having minimal impact on natural gas prices and competition for the fuel.”
The report also found that retail prices for compressed natural gas (CNG) and liquefied natural gas (LNG) will remain attractive compared to diesel and gasoline even if natural gas prices increase significantly. Currently, about 20 percent of the retail CNG price is attributable to the raw natural gas cost. Even if natural gas prices double from $4/MMBtu to $8/MMBtu, the commodity component of retail CNG prices will be about 40 percent, and CNG will cost about $2.20 per gallon of gasoline equivalent.
ACSF retained Navigant Consulting, Inc. to partner in the scenario development and to conduct some of the analysis. The report includes data tables with assumptions and results.
