ScanArc Plasma Technologies AB applications

Hydrogen is traditionally produced by water electrolysis (H2O ↔ ½ O2+ H2) , but can be also produced by methane pyrolysis (CH4↔ C + 2 H2) using for example ScanArc´s plasma technology as heat source. The efficiency of the pyrolysis reaction is highest at temperatures above app. 1000 C. To produce hydrogen by pyrolysis it takes “only” 38 kJ of energy per 1 mol of produced H2 compared to 286 kJ of energy needed when using water electrolysis.
