DGE Is Encouraged as a Threat to GGE Is Perceived
NGVAmerica is urging its members to get involved with National Institute of Standards and Technology deliberations on an official diesel gallon equivalent measure comparable to the gasoline gallon equivalent established in 1994. The association notes that a key meeting will be held later this month in Albuquerque.
An officially sanctioned DGE would help fuel buyers compare the cost of natural gas with diesel, just as the GGE allows natural gas to be compared with gasoline (F&F, June 20, 2012).
The NIST-affiliated National Conference of Weights and Measures, however, is concerned that the existing GGE does not accurately reflect the energy content of different grades of gasoline.
A Variable Equivalency Mechanism?
“Consequently,” states a Federal Register notice about the New Mexico meeting, “many weights and measures officials are reluctant to consider adding other energy ‘equivalency’ values for additional fuels unless some mechanism is established to ensure that all of these energy equivalency values are routinely updated to reflect the current energy content (i.e., Joules/BTUs) of gasoline and diesel fuels and various blends of these products with alternative fuels.”
NGVAmerica is concerned about the “equivalency” concern, and how it might threaten the continued existence of the GGE: “If our industry is not more vocal,” the association has told members, “it is possible that NCWM could recommend that CNG and LNG be dispensed in pounds without use of an equivalency factor.
‘That Option Would be Problematic’
“We believe that that option would be problematic as it does not provide useful information to consumers and potential customers, and it does not align with the movement to tax alternative fuels based on energy content.”
NGVAmerica further notes that the DGE proposal is currently an NCWM “discussion item,” but could become a “voting issue” this summer if there is enough support.
The 99th Interim Meeting of the National Conference on Weights and Measures is being held January 19-22 at the Hotel Albuquerque.
