A groundbreaking study centered on the conversion of waste plastics into high-value graphene has unveiled a new method for producing hydrogen that could potentially revolutionize the emerging green hydrogen industry. This breakthrough not only offers a sustainable solution for recycling the approximately 6.3 billion tons of plastic waste globally but also yields high-quality hydrogen gas, a clean fuel. Moreover, the process produces graphene as an end product, rendering the entire procedure economically viable. Details of this breakthrough are outlined in a recent paper published in Advanced Materials.
The cost-effective production of green hydrogen has been a significant barrier to scaling up the industry, as it has been more expensive compared to conventional fossil fuels. Although hydrogen is widely used in various industrial applications, the vast majority of it is produced from fossil fuels, categorized as gray hydrogen. Green hydrogen, produced from clean energy sources, constitutes only a small fraction of the current hydrogen market.
