NGV U.P.-T.I.M.E. Project Background

Improving the natural gas vehicle (NGV) industry through

real-world data analysis of maintenance & operational costs for fleets in the freight and goods movement sector

The natural gas vehicle (NGV) industry lacks comprehensive analysis and metrics on maintenance costs because users are siloed by various use cases or competing in similar verticals.In addition, vehicle and engine manufacturers have been reticent to make this data widely available. Together this has led to a paucity of available information for current and prospective NGV users.


There is little publicly available data that clearly compares the relative maintenance costs of NGVs and current diesel trucks with modern exhaust after-treatment systems to capture recent NGV technology advancements, validate claims of NGVs' lower total cost of ownership, and NGVs' potential to lower operating costs, improve energy security, and cost-effectiveness nationwide.


NGV U.P.-T.I.M.E. plans to bridge this information gap and facilitate an unbiased analysis project drawing on a diverse data set of national fleets to provide robust results to the broadest stakeholder group.
