Hydrogen is viewed as a promising alternative to fossil fuel, but the methods used to make it either generate too much carbon dioxide or are too expensive. Rice University researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that could more than pay for itself.

    How much energy is used to do so and how much CO2 is released as part of the process?

      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.

      If they’re making graphene and hydrogen then there can’t be much left over can there?
