Hydrogen technology has existed for decades, but only now has begun a serious study on its use for electric cars.

Hydrogen cars are being tested today by many “type concept” vehicles like the BMW H2R racing vehicles, GM Hy-wire, and the Honda FCX Clarity.

Are hydrogen cars are all the same? Two main types of hydrogen-powered vehicles:

1. Hydrogen Cars

2. Hydrogen Fuel Cell Cars.

Hydrogen cars like the BMW H2R (Hydrogen Record Car “) runs on liquid hydrogen fuel. It carries liquid hydrogen tank and use it for fuel in internal combustion engines.

A Hydrogen Fuel Cell Car like the Honda FCX Clarity uses a hydrogen fuel cell that converts hydrogen directly into electricity which powers an electric motor or motors.

There is also a third type of hydrogen-powered cars that get a lot of press today. Most people call it “Hydrogen Gas Saver” but known by other names such as “HHO hydrogen cars” or “Hydrogen assisted vehicle” but no matter what you call, it is any ordinary vehicle that uses hydrogen generator to supplement and enhance fuel mileage gas. Users claim the hydrogen generator to increase gas mileage to the tune of 50% and better gas mileage.

Here’s how it works: The car has been generating electricity to keep the battery charged. When you route the electrical current through a hydrogen generator that is filled with water and baking soda, hydrogen and oxygen produced can greatly improve the efficiency of any gas engine. Hydrogen is what is known by chemists as An energy carrier. An energy carrier is a substance or phenomenon that can be used to produce mechanical work or heat or to operate chemical or physical processes. In layman’s terms that means a 1 +1 = 3 type of effect when introduced in a car engine.
