Trillions of tons of buried hydrogen: Clean energy gold rush begins (newatlas.com)

There's enough natural hydrogen trapped underground to meet all projected demands for hundreds of years. An unpublished report by the US Geological Survey identifies it as a new primary resource, and fires the starter pistol on a new gold rush.

More greenwashing by natural gas companies. Utter nonsense. Check the facts.

As of 2020, most hydrogen is produced from fossil fuels, resulting in carbon dioxide emissions.[92] Hydrogen produced by this technology has been described as grey hydrogen when emissions are released to the atmosphere, and blue hydrogen when emissions are captured through carbon capture and storage (CCS).[93][94] Blue hydrogen has been estimated to have a carbon footprint 20% greater than burning gas or coal for heat and 60% greater when compared to burning diesel for heat, assuming US up- and mid-stream methane leakage rates and production via steam methane reformers (SMR) retrofitted with carbon dioxide capture.[95]

We're talking about H2 here, not CH4. And we're talking mining, not producing.

I can produce H2 from H20 in my kitchen. Done it lots of times! Of course that nets less energy than it took to extract.

Mining is hardly free from an environmental standpoint. Of course nothing is, but reading the speculation about this it seems very unlikely that mining will even get started anytime soon. It's very exploratory both in the where and the how. If you're talking about the next few decades you are talking about traditional fossil fuel.
