Talk:Timeline of hydrogen technologies

2000's
why isn't there a section for the 2000's? i'd think there have been a LOT of innovations since 2000. and why is 2004 listed there under the 1990s? —Preceding unsigned comment added by 67.155.113.198 (talk) 21:25, 7 January 2009 (UTC)
 * 2000s added, feel free to add what you think belongs on the list. Mion (talk) 00:52, 8 January 2009 (UTC)

When was it discovered that the gas has the formula H2, ie. that the gas consists of molecules that are made of two atoms of hydrogen? — Preceding unsigned comment added by 178.191.108.182 (talk) 20:39, 21 August 2016 (UTC)

Conjecture?
The timeline image of future hydrogen adoption seems to be pretty much speculation, however it is presented as fact. Does this meet wikipedia's standards?? — Preceding unsigned comment added by Scottt (talk • contribs) 22:16, 17 March 2021 (UTC)
