Hydrogen is not very soluble in water 131.111.85.79 (talk) 14:48, 3 March 2023 (UTC)[reply]

So what would you like in the article? Presumably the extracted hydrogen is in the gas phase. Mention here:[1]. Graeme Bartlett (talk) 21:33, 3 March 2023 (UTC)[reply]

I thought we were living in 2023. Maybe African American Hydrogen?

oh white, pure. got it. 2600:1700:1061:7010:4572:B53D:9084:EA93 (talk) 03:19, 30 October 2023 (UTC)[reply]

See https://www.usgs.gov/news/featured-story/potential-geologic-hydrogen-next-generation-energy which says that the image is PD as created by USGS.

The article reads "A closely related artificially produced form of hydrogen is green hydrogen which is produced from renewable energy sources such as wind or solar energy."

It is similar in that burning this (purified) hydrogen does not cause new CO2 emissions but it is also similar to traditional hydrocarbons of a resource (hydrogen, oil, gas) being drained way above it's natural replishment rate. As such a statement that is related to any kind of particular "color of hydrogen" is dubious. 2A02:3037:309:846B:4120:B805:4C65:77B9 (talk) 16:26, 12 February 2025 (UTC)[reply]

I agree. I've removed it the sentence that followed as they seem off-topic. It doesn't add to the phrase "hydrogen produced in industry":

A closely related artificially produced form of hydrogen is green hydrogen which is produced from renewable energy sources such as wind or solar energy. Non-renewable forms of hydrogen include grey, brown, blue or black hydrogen which are obtained from the processing of fossil fuels.^[1]
