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.

      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?
