Rice team produce hydrogen and graphene from waste plastic at zero net cost

Posted On: 2024-04-02

Rice University researchers have found a way to harvest hydrogen and graphene from plastic waste using a low-emissions method that could more than pay for itself. By comparison, ‘green’ hydrogen that is produced using renewable energy sources to split water into its two component elements costs roughly five dollars for just over two pounds, and 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.
