Hydrogen is an element that exists in abundance all over the earth. It can be found in water and natural and renewable matter such as plants, compost materials, even algae. Thanks to its abundance, hydrogen can be converted into hydrogen gas fuel for many of the same uses as fossil fuels. Hydrogen gas fuel in its purest form must be obtained by the separation of the hydrogen’s chemical bond to those elements. When hydrogen gas fuel is blended with pure oxygen and ignited the only resulting emissions are heat and water! Isn’t it smart to run your car on water!

Each method of distilling the hydrogen to it purest form has its own unique set of pros and cons, from emissions generated by the refining process to finding the most cost effective method of producing hydrogen gas fuel. Currently, steam methane reforming is the most popular method in the United States.

Producing enough hydrogen gas fuel to support mainstream use would likely require new infrastructure, making start-up costs an expensive proposition. Current technology such as electrolysis (passing of electrical current through water in an ionic transfer device) can be adapted on a larger scale by using electricity generated through methods such as windmills or solar panels. In addition, geographic concerns will play a major role in location choices for any hydrogen production facility as ideally any such facility requires a large expanse of open space and should be located away from densely populated areas. However, zero greenhouse gas emissions in the electrolysis method make this a worthwhile, long-term venture.

Hydrogen is an extremely flexible fuel as it can be stored and transported in both liquid and gas forms. Hydrogen gas fuel can be transported in its vapor form roughly one to two hundred miles from the refining facility. For long distance transport up to one thousand miles the hydrogen is transported in liquid form requiring specially designed super-insulated tanks.

Hydrogen gas fuel has the greatest energy to weight ratio of all known and commercially available fuels. When compared to gasoline, hydrogen gas fuel produces roughly three times the amount of energy we obtain from gasoline (with no carbon dioxide or sulfur emissions) and over six times the amount of energy we obtain from coal. Nice hypermiling driving.

Hydrogen gas keeps its efficiency through differing ranges of air fuel mixtures than gas, making it more efficient combustion-wise. The rating of hydrogen gas fuel is equal to that of an octane rating of 130, much greater than the highest octane gas that is available to the consumer at the gas station.

Hydrogen gas fuel can be used to power everything from cities to cell phones. Vehicles ranging from scooters to spacecraft can be operated using hydrogen gas. Consumer vehicles can be produced or even retrofitted to burn this earth friendly fuel. Time will tell if hydrogen gas becomes a viable alternative as gas prices continue to soar.
