Dazo Water Fuel Technology

1. INTRODUCTION

1.1 BACKGROUND

Today, virtually all commercial trucks are powered by diesel fuel, while private cars are fueled by gasoline. While these petroleum-based fossil fuels have served society well for many years, their supply is limited, and their use creates pollution that contributes to poor air quality in many areas. Supported by our National Energy Policy, a new generation of technologies is currently being developed that allow the use of hydrogen as a fuel to power cars and trucks (see Table 1). In the future, hydrogen may be used in one of three ways to power vehicles:

•To produce electricity in a fuel cell,
•As a replacement for gasoline or diesel fuel in an internal combustion engine, or
• As a supplement to gasoline or diesel fuel used in an internal combustion engine.

Table 1. Why Hydrogen?
1.To reduce harmful pollution from vehicle exhaust
2.To reduce carbon dioxide (CO2) emissions, which contribute to global warming
3. To reduce our growing dependence on foreign oil

This document was developed by the Federal Motor Carrier Safety Administration as a reference for commercial vehicle fleet owners and operators who use hydrogen fuel in their vehicles, and it primarily focuses on safety. All motor fuels, including diesel fuel, gasoline, and natural gas pose risks of fire and explosion if handled improperly. Hydrogen is no different.

While there are risks, hydrogen can be as safe, or safer, than diesel and other fuels when vehicles and fuel stations are designed and operated properly.

While safe, hydrogen is different from other motor fuels, it has significantly different physical and chemical properties that affect how it must be safely stored and handled. Therefore, this document was designed to provide basic information about hydrogen properties and characteristics, as well as an overview of the vehicle systems than might use hydrogen fuel. It also provides basic guidelines for how vehicles, as well as fuel stations and maintenance facilities, should be designed and operated if hydrogen will be used. This information is provided so that fleet owners and operators will know what to look for—and what to do and not do—when using hydrogen fuel for their vehicles.
