The paper shows that low-temperature plasma initiated in a liquid medium in the interelectrode discharge gap is capable of decomposing hydrogen-containing organic molecules with formation of gaseous products with the volume part of hydrogen higher than 90% (according to gas chromatography data). Tentative assessments of the energy efficiency with regard for hydrogen and feedstock combustion value and energy consumption have shown an efficiency factor of 60-70% depending on the source mixture composition. Theoretical model calculations of discharge current and voltage have been performed; the values are in a good agreement with experimental data.
