> The plasma process developed by the program team overcomes these limitations. Its ultra-high-temperature operation rapidly breaks down polymer structures while suppressing carbon formation by using 100% hydrogen fuel. As a result, the process not only secures long-term operational stability but also enables the selective conversion of over 70–80% of the outputs into ethylene and benzene. Notably, even waxes—previously unusable in pyrolysis—could be converted at more than 80% selectivity, boosting energy efficiency.
Can this hydrogen plasma plastic recycling process be tuned down to intentionally produce graphene as a byproduct?
> Maybe rGO reduced graphene oxide wafers could be deoxidized with hydrogen plasma, thus eliminating PFAS-containing photoresist
Another hydrogen plasma question and opportunity:
Would there be net Hydrogen from deoxidizing Aluminum (Al2O3) with Hydrogen cold plasma, maybe through a water loop? Would that sterilize the water? Would that demineralize the water? Hydrolysis and/or a fuel cell?
I'm not sure how an H2 plant in Saudi Arabia, due to start producing in 2027, relates to my question.
If the actual goal is CO2 reduction, and 99% of H2 production is "full-carbon" - https://en.wikipedia.org/wiki/Hydrogen_production - then why aren't they just building a conventional DC, but with no-water-use cooling? The electricity could come from solar arrays & wind farms, with batteries or something for storage.
Vs. if it's just a "Hydrogen is Trending" PR exercise - that seems a much better fit for the facts.
> As of 2023, less than 1% of dedicated hydrogen production is low-carbon, i.e. blue hydrogen, green hydrogen, and hydrogen produced from biomass.
There is at least one large green hydrogen producer.
I don't know how that changes the total energy problems of hydrogen production and storage. Is it that new methods of hydrogen production have more efficiency?
Let's hope for more green hydrogen production.
A plentiful catalyst like Aluminum might make more green hydrogen, for which there are numerous applications like deoxidizing aluminum and deoxidizing reduced graphene oxide wafers for semiconductor and superconductor production.
Am I overlooking their mention of the hydrogen source? 'Cause to quote Wikipedia -
> Nearly all of the world's current supply of hydrogen is created from fossil fuels.
> As of 2023, less than 1% of dedicated hydrogen production is low-carbon, i.e. blue hydrogen, green hydrogen, and hydrogen produced from biomass.

Is hydrogen from would-be-landfilled unsorted plastics (with plasma, EM induction, and/or flash heating) "teal" hydrogen?
Blue because sourced from hydrocarbons, Green because diverting plastic from landfills to hydrogen and graphene?
