Feasibility of gasifying mixed plastic waste for hydrogen production and carbon capture and storage

Abstract Waste plastic gasification for hydrogen production combined with carbon capture and storage is one technology option to address the waste challenge. Here, we conducted a techno-economic analysis life cycle assessment assess this option. The minimum selling price of 2000 oven-dry metric ton/day mixed plant US$2.26–2.94 kg −1 hydrogen, which can compete fossil fuel (US$1.21–2.62 hydrogen) current electrolysis (US$3.20–7.70 hydrogen). An improvement outlines roadmap reducing average from US$2.60 US$1.46 be further lowered US$1.06 if credits are close costs along low feedstock cost. results show that derived has lower environmental impacts than single-stream plastics.
