Join fellow fleet leaders to work together to advance the NGV trucking industry

The objective of this Department of Energy funded natural gas vehicle (NGV) maintenance study is to complete a comprehensive study that documents maintenance costs, technology solutions, or best practices capable of reducing maintenance or other related ongoing costs for medium- and heavy-duty NGVs used in freight and goods movement, relative to equivalent base diesel models, including emissions after-treatment systems. The study also aims to identify specific end-use applications or duty-cycle variables that affect maintenance costs significantly and disproportionately when comparing natural gas and diesel engine systems.

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.

Project Overview

NGV UP-TIME will complete a comprehensive study documenting maintenance costs, technology solutions, and best practices capable of reducing maintenance or other related ongoing costs for medium-/heavy-duty NGVs used in freight and goods movement, relative to equivalent base diesel models, including emissions after-treatment systems. The study will provide fleets, natural gas vehicle (NGV) industry stakeholders, and other end-users with relevant, real-world information through a proven, multi-data set analysis approach detailing NGV maintenance costs to improve total cost of ownership calculations and to determine the maintenance cost differences between NGV technology generations (current state-of-the-art and current advanced clean diesel engines) for relevant medium and heavy-duty freight and goods movement applications.

– Gather data set on NGV & Diesel Trucking Operations in Freight & Goods Movement Fleets.
– Quantify the difference in maintenance and operational cost in NGV’s and diesel vehicles.
– Identify and quantify technology & improvements between older and newer generation NGV’s.
– Assess individual NGV fleets to identify opportunities to enhance operations using legacy & newly generated data
