I don’t recognize the article’s definition of blue hydrogen, which I believe is normally used to refer to hydrogen derived from natural gas, not “from water”

- CyanBird 4y agoCorrect, blue hydrogen is hydrogen derived from fossil fuels, tho it doesn't need to necessarily be directly obtained from natural gas, could be just that natural gas or even coal is used for driving electrolysis
- shagie 4y agoThere's an entire spectrum of hydrogen "colors" - https://hydrogen-central.com/cummins-hydrogen-rainbow-colors/ https://hydrogen-central.com/cummins-hydrogen-rainbow-colors... and https://rail.ricardo.com/news/opinion-decoding-the-hydrogen-t-rainbow https://rail.ricardo.com/news/opinion-decoding-the-hydrogen-... Getting hydrogen from water is one of: red or purple (nuclear - depending on process), yellow (solar), green (other renewables).
- ncmncm 4y agoBlue hydrogen is a mythical beast, H2 made from NG and the carbon captured, somehow. It is not actually produced, but poisons discussion. Very soon NG will be too expensive to bother extracting, as renewables cost continues plummeting. It will all be green. People will laugh at us for having thought up blue hydrogen.
