Waste Plastic Gasification: A Viable Pathway for Hydrogen Production in Emerging Economies

Modelling · 2026

Key Findings

01Plastic waste can produce 21,997 tonnes of H2 annually at a levelised cost of $2.88/kg.
02The optimal network includes four facilities in Muscat, Sohar, Salalah, and Nizwa.
03This infrastructure can process 275,000 tonnes of plastic waste and avoid 137,000 tonnes of CO2-eq.
04Feedstock availability limits production to 24% of base case demand, necessitating integration with other hydrogen production methods.
05Hydrogen yield and capital expenditure (CAPEX) are critical cost drivers.
