Hydrogen production
Arrgh, dummy edit so I can fix a typo in my previous edit summary. Should have said, "Explanations of color codes had been removed from the body of the
Hydrogen economy article. Expanded the lead here to include the key color codes (gray, blue, green). This fleshes out the lead here and makes the Hydrogen economy article make more sense. Also removed/consolidated repetition and defined some jargon."
