How much energy is used to do so and how much CO2 is released as part of the process?
Comment on Making hydrogen from waste plastic could pay for itself

“We know that polyethylene, for example, is made of 86% carbon and 14% hydrogen, and we demonstrated that we are able to recover up to 68% of that atomic hydrogen as gas with a 94% purity,” Wyss said. "Developing the methods and expertise to characterize and quantify all the gases, including hydrogen, produced by this method was a difficult but rewarding process for me

Doesn’t say, but if the electricity used is from renewables, then it’s irrelevant if it can produce graphene at that price
Found this:
Compared to commercial methods for carbon nanotube production that are being used right now, ours uses about 90% less energy and generates 90%-94% less carbon dioxide," Wyss said.

So, the get 8% of the bottle into a usable form . . . by turning plastic bottles into gases. So where does the rest of the bottle go? How much energy is used for that?

Second paragraph…
In this work, we converted waste plastics—including mixed waste plastics that don’t have to be sorted by type or washed—into high-yield hydrogen gas and high-value graphene

Not quite. This is greenwashing. the company funding the research is the world’s largest offshore drilling company. You got suckered or are trying to sucker in other people

Rice University are greenwashing?

The army is one of the biggest ghg emitters in the world. Now I’m certain you’re just sharing propaganda. Why would a fossil fuel company push hydrogen technology? Because hydrogen production requires fossil fuels.

Woah there buddy. You said it was the biggest offshore drilling company a minute ago.
Hydrogen does not require fossil fuels…
This company makes ammonium nitrate from renewable energy and green hydrogen

Maybe pump your brakes calling everyone propagandists until you actually understand the technology
