What is Hydrogen Fuel Hydrogen is high in

What is Hydrogen Fuel? • Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution. NASA has used liquid hydrogen since the 1970 s to propel the space shuttle and other rockets into orbit. Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct - pure water, which the crew drinks.

Advantages • Higher efficiency than diesel or gas engine. • Operate silently, and are therefore ideally suited for buildings such as hospitals. • Fuel cells can eliminate pollution, the only by-product at point of use is water. • Since hydrogen can be produced anywhere there is water and a source of power, generation of fuel can be distributed and does not have to be grid-dependent. • Operating times are much longer than with batteries, since doubling the operating time needs only doubling the amount of fuel and not the doubling of the capacity of the unit itself. • The maintenance of fuel cells is simple since there are few moving parts in the system.

Disadvantages • Storage Issues Apart from taking much time to separate the compounds of hydrogen, this element is also a challenge to move and transport. Compared to oil which can be channeled through pipelines and coal which can be moved to one location to another using trucks, transporting hydrogen can be expensive. This is one obvious setback of this element since storage and transport can be considered impractical. • Highly Flammable Skeptics have expressed concerns on the safety of using hydrogen fuel cells in cars and other applications because of the fear of explosion especially in higher concentrations. Although scientists have tested it several times, they do not rule out that this element is flammable. In case of fire, hydrogen flame is not seen in daylight, making it dangerous for fire fighters who will respond to the incident. This concern is also placed on liquid hydrogen. Being colorless and odorless, inhalation and ingestion is possible without being noticed and if this happens, asphyxiation can happen to people who are in an area without proper or no ventilation. • Hydrogen fuel cells do not work at very low temperatures, and they may also require a platinum catalyst (platinum is expensive and prone to contamination by impurities)
