“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, as it can potentially produce graphene at 5% of the current price
Found this re co2
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.
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
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.
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?
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
Sounds promising but remember that when there’s news of hydrogen, there’s a fossil fuel company behind it
This is from SLB, the company that Kevin Wyss works for. Took about 30 seconds of googling to find out that it’s essentially a greenwashing fossil fuel company
Who do you think is going to engineer the transition to a circular economy…my money is on actual engineers, not code monkeys
You could also, you know, read the article…
By comparison, “green” hydrogen—produced using renewable energy sources to split water into its two component elements—costs roughly $5 for just over two pounds. Though cheaper, most of the nearly 100 million tons of hydrogen used globally in 2022 was derived from fossil fuels, its production generating roughly 12 tons of carbon dioxide per ton of hydrogen.
“The main form of hydrogen used today is ‘gray’ hydrogen, which is produced through steam-methane reforming, a method that generates a lot of carbon dioxide,” said James Tour, Rice’s T. T. and W. F. Chao Professor of Chemistry and a professor of materials science and nanoengineering. "Demand for hydrogen will likely skyrocket over the next few decades, so we can’t keep making it the same way we have up until now if we’re serious about reaching net zero emissions by 2050
So this is either a big oil corp spending pennies on theorycrafting some exciting buzzword technosolutions
Or
A big oil corp which figured out that if they want to stay relevant for more than 10 yrs they need to diversify into other energy sources. With all the deserved hate they attract such companies are probably most likely to invent and implement aomething like this at scale.
It doesn’t change the fact that they should be nationalized asap and their decisionmakers jailed.
fuck off shill. Just realized you’re a fucking mod of the brexit community. I should have known not to use words with more than 1 syllable or 8 characters
