message: Is there any objection to moving this article from "Hydrogen storage" to Hydrogen Storage", to properly capitalize? If my suggestion is improperly capitalized for wikipedia articles, then by all means, let me know so that i may change my ways. But I always thought that aritcles were capitalized.--Vox Causa 22:06, 27 September 2006 (UTC)

message: The article says, "Even liquid hydrogen has worse energy density per volume than hydrocarbon fuels such as gasoline by approximately a factor of four. In fact, there is about 50% more energy in a gallon of gasoline (121 MJ) (0.9 lb) than there is in a gallon of liquid hydrogen (80 MJ)(0.6 lb)."
But if there's only 50% more energy in a gallon of gasoline than there is in a gallon of liquid hydrogen, then wouldn't liquid hydrogen have worse energy density per volume than gasoline by a factor of only 1.5, rather than by a factor of 4?

replies: text: The problem is that the figures in the first sentence are all wrong. What it means to say is that there's 50% more HYDROGEN in a gallon of gasoline than there is in a gallon of liquid hydrogen. But that doesn't mean there's only 50% more energy in the gasoline, because the carbon in the gasoline contributes substantially to energy of burning. See the point? I'll fix the text about confusing amounts of hydrogen with energy. SBHarris 00:58, 23 June 2007 (UTC)
thread_title:  density 

message: Those new references in the carbon section are mal-formed, and thus pretty useless.  I'm sorely tempted to revert that whole edit.  There have been so many contradictory specific claims about storage in carbon over the years you simply cannot say "carbon can store this much:  see this reference" with any confidence.  It's cherry picking.
Please, fix those references.

thread_title:  Carbon 

message: The first cite links to a PDF document and no page number is provided. The statement that the cite seems to refer to is that the 2005 targets weren't met. The document referenced doesn't seem to mention to 2005 targets, in fact the table in the document has 2007 targets where the wiki article has 2005 targets. In short, the reference provided is inadequate to support the claims made.  —Preceding unsigned comment added by 99.240.215.79 (talk) 17:43, 17 August 2008 (UTC)

message: Perhaps that converting hydrogen to hydrogen sulphide would be a better method to store it ? Hydrogen sulphide already occurs naturally (ie in cenotes, ...) so the creation aswell as the storage (natural occurence means storage possible at room temperature) would be simple. Are there any references or information about this, and if so, include to article.

replies: text: If it was just about hydrogen atoms, you'd use water.  Hydrogen storage is about energy storage.  In hydrogen sulphide the hydrogen is tightly bound.  That means you're "storing" a low energy state, not a high energy state. 121.45.214.40 (talk) 06:09, 3 March 2012 (UTC)

message: It's not in the chart and it's not even explicitly mentioned. Just the group where it belongs.
It's mentioned in a group that gives the impression that it's not available outside laboratory environment.

message: Does this 14% capacity claim significant enough to be included into this article?  — Preceding unsigned comment added by 202.153.128.82 (talk) 09:17, 12 October 2011 (UTC)
replies: text: No.  A press release is not a reliable source.  Particularly as: a) While Rafiee has published a lot of stuff on graphenes, I can't see any that look like they relate to H2 storage; and b) Rafiee explicitly misrepresents how his claimed capacity related to the US DoE targets.  121.45.214.40 (talk) 06:20, 3 March 2012 (UTC)
thread_title:  carbonite substances 

message: Methane seems to be a much more stable gas (easier to store), so it seems useful to convert hydrogen into this (atleast for use as a fuel). I thus added Converting hydrogen to methane using the Sabatier-process at the see also section. Perhaps the gases can be quickly compared ?

message: Hello fellow Wikipedians,
I have just added archive links to  on Hydrogen storage. Please take a moment to review my edit. You may add  after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add  to keep me off the page altogether, but should be used as a last resort. I made the following changes:
