Question

I need web sites on information of hydrogen energy post at least 2?

Answer 1

The problem with hydrogen is that it does not occur as an element in nature.  This requires that energy be expended to disassociate some other element into hydrogen and whatever else.

While water contains 2 hydrogen atoms and 1 oxygen atom, there is a net energy loss to split the split molcule and the subsequent efficiency losses in burning it as a fuel source.

The current feedstock for most commercial hydrogen production is natural gas (predominately CH4), which  leaves carbon monoxide and/or carbon dioxide as a by-product, along with many other trace compounds.

Hydrogen is best considered as a pollution reduction/relocation measure (if used for vehicle fuel) as the emissions would be centralized at a power facility and regulated/controlled there, rather than thousands of individual engines.

It shouldn't be considered as an energy SOURCE!

Answer 2

here you go. hopes it helps good luck :)

Answer 3

Interest in alternative fuels has never been greater. Hydrogen is one of the key fuels being considered because it is renewable, abundant, efficient, and unlike other alternatives, it produces no emissions. here are your hydrogen energy information web sites;

Answer 4

One of the biggest claims that hydrogen technology proponents make is that hydrogen will drastically reduce the problem of human-induced global warming through the reduction of greenhouse gas emissions. The problem with this argument is that burning hydrogen does produce a greenhouse gas, and a lot of it at that: I am, of course, talking about water vapor. Gaseous H20 accounts for 60% of all greenhouse gases, and serves an important purpose in moderating the earth's temperature. Water vapor does have one clear advantage over carbon dioxide as an emissions gas: carbon dioxide only leaves the atmosphere via fixation in photosynthesis, polar ice absorption, or solution in water reservoirs, while water can exit the atmosphere simply by raining. But while hydrogen burning does, in fact, produce none of the traditionally worrisome carbon-based greenhouse gases (carbon dioxide and methane), the jury is still out on its total impact as a substitute for fossil fuel.
