Here, we propose the plasma effective driving factor (PED) as a physics-informed engineering descriptor for evaluating plasma-reaction-driving capability in DBD reactors. PED integrates three coupled aspects of plasma activation: electric-field-driven electron acceleration, electron–molecule collision efficiency, and reactor-scale participation of active microdischarges. Using CH4 splitting as the primary reaction system, we show that PED captures plasma discharge and performance variations not consistently resolved by conventional electrical parameters. Extension to published DBD systems suggests the potential of PED for comparative analysis beyond the present CH<sub>4</sub> splitting system. Overall, PED provides a practical engineering framework for relating discharge-state variation to chemical reaction response and offers a comparative basis for evaluating plasma-reaction-driving capability across different DBD conditions.\n\n{{Pearce publications notice}}\n\n== See also ==\n\n* [[Comparative techno-environmental analysis of grey, blue, green/yellow and pale-blue hydrogen production]]\n* [[Open-Source DC-DC Converter Enabling Direct Integration of Solar Photovoltaics with Anion Exchange Membrane Electrolyzer for Green Hydrogen Production]]\n* [[Open-source Hardware Design of Modular Solar DC Nanogrid]]\n* [[Modular Open Source Solar Photovoltaic-Powered DC Nanogrids with Efficient Energy Management System]]\n* [[Experimental integration of a foam-based floating photovoltaic (floatovoltaic) system with an anion exchange membrane electrolyzer for 5 kW-Scale green hydrogen production]]\n* [[Literature review: LCA of different types of hydrogen production]]\n\n{{Page data\n| keywords = Chemical Engineering,\nPlasma Physics,\nHydrogen,\nCarbon,\nPlasma Engineering,\nHydrogen Energy,\nPlasma,\nHydrogen Production,\nMethane,\nDielectric Barrier Discharge Plasma,\nDielectric Barrier Discharge,\nHydrogen Economy\n| sdg = SDG07 Affordable and clean energy, SDG08 Decent work and economic growth, SDG09 Industry innovation and infrastructure\n| authors = User:J.M.Pearce\n| organizations = FAST, Western\n}}\n\n[[Category:FAST Completed]]\n[[Category:FAST methods]]\n[[Category:Distributed manufacturing]]\n[[Category:hydrogen]]"}
