Question:

What are the problems of using hydrogen as auto fuel?

I have heard that hydrogen is another fuel alternative and that the byproduct is water.why then, are we not using hydrogen??? Are their pitfalls involved? Do we have the technology?

Answer:

Hydrogen fuel difficulties -- While fuel cells themselves are potentially highly energy efficient, and working prototypes were made by Roger E. Billings in the 1960s, at least four technical obstacles and other political considerations exist regarding the development and use of a fuel cell-powered hydrogen car. Currently, hydrogen fuel cells are costly to produce and fragile Freezing conditions are a major consideration because fuel cells produce water Although service life is coupled to cost, fuel cells have to be compared to existing machines with a service life in excess of 5000 hours Hydrogen has a very low volumetric energy density at ambient conditions, equal to about one-third that of methane. Even when the fuel is stored as a liquid in a cryogenic tank or in a pressurized tank, the volumetric energy density (megajoules per liter) is small relative to that of gasoline. Because of the energy required to compress or liquefy the hydrogen gas, the supply chain for hydrogen has lower well-to-tank efficiency compared to gasoline Current technologies for manufacturing hydrogen use energy in various forms, totalling between 25 and 50 percent of the higher heating value of the hydrogen fuel, to produce, compress or liquefy, and transmit the hydrogen by pipeline or truck.[19] Electrolysis, currently the most inefficient method of producing hydrogen, uses 65 percent to 112 percent of the higher heating value on a well-to-tank basis In order to distribute hydrogen to cars, the current gasoline fueling system would need to be replaced, or at least significantly supplemented with hydrogen fuel stations Political considerations -- Most of today's hydrogen is produced using fossil energy resources.[28] While some advocate hydrogen produced from non-fossil resources, there could be public resistance or technological barriers to the implementation of such methods.

Dont quote me, but i think that i read somewhere that hydrogen is highly flammable. We do have the technology. Helium and Ethanol on the other hand are better alternative fuels. Engines and cars round the world must be mondified to consume these alternative resources, which isnt so easy when there are a billion or so cars around the world. hope this helps

The only byproduct when you burn the hydrogen is water, yes. However, you have to get the hydrogen from somewhere in the first place, and right now 96% of our hydrogen comes from fossil fuels. That's just one problem. The other huge problems are lack of transportation and storage infrastructure (few hydrogen fueling stations), and cost (currently fuel cells use platinum - incredibly expensive).

It is energy intensive to produce and store. It is another way for the energy companies to make a buck. But, there are people working on ways of producing usable h2 that can be produced at site by the user. Alternative fuels and ways of driving modes of transportations is becoming exciting the future has so many possibilities if we don't allow the fuel produces to determine the market. The link below was a man who is now dead but had a great idea.

Any-body with water and electricity at hand, can produce hydrogen. The trick is to store enough high-quality gas and to pump it into a vehicle's tank, without blowing yourself up in the process. These three aspects of hydrogen use are blocked by big oil. The actuallity of successfully administering such an endeavor economically is held hostage to the political climate,of today. Inform the oil cartel to 'kiss-off' and the world goes boom. The rich will survive only to institute a new level of surpremacy. We the people have the power to begin a new order of decient and moral society. We must begin by banishing those who choose to hold us hostage to thier greedy ways. Oppression and manipulation must be elliminated first and foremost.
