Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Hydrogen (http://periodic.lanl.gov/elements/1.html). Additional text was taken directly from the Elements database 20001107 (via dict.org (http://www.dict.org)), Webster's Revised Unabridged Dictionary (1913) (via dict.org (http://www.dict.org)) and WordNet (r) 1.7 (via dict.org (http://www.dict.org)). Data for the table was obtained from the sources listed on the main page and WikiProject Elements but was reformatted and converted into SI units.
Decomposing Natural Gas
I think getting hydrogen from "decomposing" natural gas is actually called "reforming hydrogen from natural gas", (using steam) but I'm not positive if this is just the name for one way of getting it. --Ben 09:01, 8 Dec 2004 (UTC) Steam reforming of natural gas (http://www.bellona.no/en/energy/report_3-1999/11193.html)
Hydrogen production
I suggest it should be a section dedicated to hydrogen production. This would avoid telling about it in the first section and allow a more complete listing of all production alternatives, e.g., add photoelectrochemy, artificial photosynthesis, and water splitting using the heat of a nuclear power plant through a chemical cycle.
It should also be more about hydrogen storage: briefly comment pressurized, liquid, and hydrides, with their advantages and draw-backs. --Philipum 09:57, 26 May 2005 (UTC)
I was wanderign why there is nt more detail on the physics side of the hydrogen atoms. Things like thermoluminescence.
Applications
"Hydrogen fuel cells are being looked into as a way to provide power with lower emissions than hydrogen burning internal combustion engines." That can't be right, and the article on Hydrogen car is clear that the only emission is water vapor. Maybe we meant "fossil fuel-burning internal combustion engines".
Well technically, hydrogen internal combustion engines would likely produce NOx emissions for the same reasons gasoline engines do. But feel free to change the article; it could probably be clearer.
Two questions here,
a. What happens if you breathe hydrogen gas? Apart from becoming dangerously flammable I mean. Let's say you still had plenty of oxygen mixed in...
b. If hydrolysis uses an electric charge to release hydrogen and oxygen gas, and oxygen-and-hydrogen isn't just flammable but -explosive-, then wouldn't it explode every time you did that? Electric current has a way of igniting things.
Answers:
a. My understanding is nothing in particular. I believe oxygen / helium / hydrogen mixes are used for ultra-high-pressure diving breathing mixtures. Your voice would sound funny, though, like helium only more so :)
b. Electrolysis doesn't mean there's a spark, or that there's ever mixed hydrogen and oxygen present. The hydrogen comes off one electrode, the oxygen off the other (or opposite sides of the fuel cell or whatever). Evand 03:49, 22 Jun 2005 (UTC)
