The conversion of CO 2 into useful chemicals is an attractive method to reduce greenhouse gas emissions and to produce sustainable chemicals. However, the thermodynamic stability of CO 2 means that a lot of energy is required for its conversion into chemicals. Here, we suggest a new catalytic system with an alternative heating system that allows minimal energy consumption during CO 2 conversion. In this system, electrical energy is transferred as heat energy to the carbon‐supported metal catalyst. Fast ramping rates allow high operating temperatures ( T app =250 °C) to be reached within 5 min, which leads to an 80‐fold decrease of energy consumption in methane reforming using CO 2 (DRM). In addition, the consumed energy normalized by time during the DRM reaction in this current‐assisted catalysis is sixfold lower (11.0 kJ min −1 ) than that in conventional heating systems (68.4 kJ min −1 ).
