| Abstract: | Electron beam plasma methane pyrolysis is a hydrogen production pathway from natural gas without direct CO 2 emissions. In this work, two concepts for a technical implementation of the electron beam plasma pyrolysis in a large-scale hydrogen production plant are presented and evaluated in regards of efficiency, economics and carbon footprint. The potential of this technology is identified by an assessment of the results with the benchmark technologies steam methane reforming, steam methane reforming with carbon capture and storage as well as water electrolysis. The techno-economic analysis shows levelized costs of hydrogen for the plasma pyrolysis between 2.55 €/kg H 2 and 5.00 €/kg H 2 under the current economic framework. Projections for future price developments reveal a significant reduction potential for the hydrogen production costs, which support the profitability of plasma pyrolysis under certain scenarios. In particular, water electrolysis as direct competitor with renewable electricity as energy supply shows a considerably higher specific energy consumption leading to economic advantages of plasma pyrolysis for cost-intensive energy sources and a high degree of utilization. Finally, the carbon footprint assessment indicates the high potential for a reduction of life cycle emissions by electron beam plasma methane pyrolysis (1.9 kg CO 2 eq./kg H 2 – 6.4 kg CO 2 eq./kg H 2 , depending on the electricity source) compared to state-of-the-art hydrogen production technology (10.8 kg CO 2 eq./kg H 2). • Techno-economic and environmental assessment of hydrogen production by electron beam plasma methane pyrolysis. • Levelized costs of hydrogen between 2.55 €/kg H 2 and 5.00 €/kg H 2 under current economic framework. • Cost-competitive hydrogen production compared to steam methane reforming and electrolysis under certain price scenarios. • Low-carbon hydrogen production with life cycle emissions between 1.9 kg CO 2 eq./kg H 2 and 6.4 kg CO 2 eq./kg H 2.
