CNG description
CNG compares the cost of any alternate fuel scenario, for any type of vehicle

CNG-CALC is an economic analysis system for alternate fuel vehicles.
With this program you can compare the cost of any alternate fuel scenario, for any type of vehicle.

It can be used to produce financial comparisons of the cost to convert vehicles (of any type) to use Compressed Natural Gas (CNG), Methanol, Ethanol, Gasoline, LNG, Diesel, Electric or Propane.  Use it for any mix of vehicles, from passenger vehicles, to diesel trucks, or forklifts.  Some of the vehicles can be dual-fuel, others can be dedicated to one fuel. 

CNG-CALC will also accommodate the costs of refueling stations.  Useful for Fleet managers , or anyone else interested in determining the economic benefit of converting any vehicle to any fuel. 

You can do a financial comparison for Ethanol, and then another for CNG, or Diesel.

CNG-CALC can also produce pressure/volume charts to calculate fill amounts based on beginning/ending pressures, temperature and molecular value of gas composition (vs. micro motion measuring devices). 

All volume amounts can be measured in either USA units or metric units.  CNG-CALC also includes a storage tank sizing module, that accesses manufacturer storage data, based on dimensions, weight guidelines and minimum equivalent gallons desired.

Financial Analysis will take into account current fuel prices, current vehicle usage, efficiencies and any dual fuel usage patterns. Depreciation schedules for vehicles are user modifiable.  CNG-CALC evaluates Net Present Value (NPV) of the investment versus the Internal Rate of Return (IRR).

Limitations:

· you are limited to using CNG for a limited number of uses. There will be a short warning period where a registration reminder screen will appear at the beginning. When that period expires, the user will not be allowed access to the menu.
