Nonthermal plasma (NTP) is being investigated as an electrically driven route for hydrogen production because energetic electrons can activate methane, water vapour and carbon dioxide without requiring the entire gas phase to reach thermochemical equilibrium. This article compares dielectric barrier discharge (DBD), gliding arc and microwave plasma systems, with particular attention to methane conversion, hydrogen yield and electrical energy demand. Published experimental results were evaluated using a common set of indicators: feed conversion, H₂ yield/selectivity, specific energy input and hydrogenenergyyield. The literature shows that reactor type and operating regime strongly determine performance. DBD is attractive for plasma-catalyst integration, gliding arc can provide high conversion at relatively favourable energy input, and microwave systems have demonstrated high-throughput hydrogen production. Catalyst addition can enhance conversion, but the gain in methane conversion does not necessarily translate proportionally into H₂ yield. The analysisthereforeidentifies energy efficiency, plasma-catalyst interaction, scale-up and product separation as the principal engineering constraints. The most promising development route is the integration of optimized discharge conditions, selective catalysts and low-carbon electricity.
