Vehicle and Infrastructure Cash-Flow Evaluation Model

VICE 2.0: Vehicle and Infrastructure Cash-Flow Evaluation Model

The Vehicle and Infrastructure Cash-Flow Evaluation (VICE) model version 2.0 is the second generation of the financial model developed by the National Renewable Energy Laboratory for fleet managers to assess the financial soundness of converting their fleets to run on compressed natural gas (CNG).

Version 2.0 Enhancements

Enhancements to version 2.0 include the ability to select the project type (vehicles and infrastructure or vehicles only), as well as decouple vehicle acquisition from the infrastructure investment, so the two may be made independently. Additionally, outputs now include a graphical presentation of investment cash flow, payback period (simple and discounted), petroleum displacement (annual and cumulative), and annual greenhouse gas savings. Also, the vehicle fleet is now built around several common conventionally-fueled fleet vehicles, both gasoline and diesel.
