1. ASSESS

The first step in moving to natural gas is to assess your operation and evaluate the opportunity to use natural gas fueled vehicles in your fleet. A review of your fleet’s operational profile – application, routes, loads, terrain – will help you to:

  • Select the suitable engine, transmission, and vehicle
  • Configure the fuel system to meet range requirements
  • Ensure the vehicle is specified performance requirements

Natural gas engines reduce emissions.  To help you understand the benefit of this emissions reduction, we’ve developed an Emissions Calculator to help calculate GHG reductions based on your application.  Economics are also a key consideration when evaluating natural gas vehicles – our Payback Calculator calculates key natural gas operational inputs.

Determining your fleet fueling strategy is an essential part of defining the application.

  • Will you be using CNG or LNG?
  • Are there public fuel stations available or will a private station be required?

These factors will help define range and fuel requirements. Range and fueling strategy are important considerations in fuel system design. Because natural gas has lower BTUs (British Thermal Unit) than diesel or gasoline, volume must be calculated in energy equivalent units. The equivalent volume of natural gas for diesel is DGE or Diesel Gallon Equivalent. CNG or LNG natural gas fuel systems are tailored to the vehicle and duty cycle.

Equally important is to review and determine your natural gas service requirements. Are there qualified natural gas service locations in the area or will your fleet be self-servicing? Cummins has an expanding network of natural gas service facilities and qualified technicians. For dealers and customers, natural gas service technician training can also be provided. Ask your local Cummins representative for more details.

Natural gas vehicle service locations require facility modifications and technician training. While Cummins does not upgrade service facilities, we provide general and technical information on upgrading and operating a natural gas facility in the Prepare section of this playbook.

Cummins Westport has developed an Initial Assessment Guide to help customers evaluate their fleet and the opportunity to transition to natural gas. This Assessment also provides inputs to the Playbook’s GHG and Payback calculators and provides additional information for our representatives to help customers with their natural gas project. There are also key questions that will provide important information to OEMs for vehicle specifications, and for service and support during operation.
