Hydrogen Cars

A hydrogen vehicle is a vehicle, such as an automobile or aircraft, which uses hydrogen as its primary source of power for locomotion. These vehicles generally use the hydrogen in one of two methods: combustion or fuel-cell conversion.

Overview

The Hydrogen cars are not only the future, they are here, now. When hydrogen cars become the status quo, the U. S. can lessen its dependence upon foreign oil, achieve lower prices at the fuel pumps and cut down on the greenhouse gases that produce global warming. The future of hydrogen cars is not a pipe dream, as there are already many hydrogen cars on the road. California and Japan have many hydrogen cars being used as fleet vehicles now.

For the past 28 years, the Los Alamos National Laboratory (LANL) has been conducting research on hydrogen fuel cells for use in transportation, industry and residential use. According to the LANL, "Hydrogen & Fuel Cell Research at Los Alamos has made significant technological advances in Polymer Electrolyte Membrane (PEM) fuel cells, Direct Methanol Fuel Cells (DMFC), and related technologies such as the electrolyzer (a fuel cell in reverse, liberating hydrogen from electricity and pure water).

Introduction

Unlike many of the hybrid and "green" cars currently on the market, hydrogen cars offer the promise of zero emission technology, where the only byproduct from the cars is water vapor. Current fossil-fuel burning vehicles emit all sorts of pollutants such as carbon dioxide, carbon monoxide, nitrous oxide, ozone and microscopic particulate matter. Hybrids and other green cars address these issues to a large extent but only hydrogen cars hold the promise of zero emission of pollutants. The Environmental Protection Agency estimates that fossil-fuel automobiles emit 1 ½ billion tons of greenhouse gases into the atmosphere each year and going to hydrogen-based transportation would all but eliminate this.

Not only that, hydrogen cars will lessen the United States' dependence upon foreign oil. The so-called "hydrogen highway" will mean less dependence upon OPEC, the big U. S. oil companies, oil refinery malfunctions and breakdowns and less resistance from oil selling nations like Venezuela and Saudi Arabia or from hostile nations who would rather sell elsewhere. Consumers will finally get a break from the never-ending rising prices at the gasoline pumps.
