Carbon Dioxide ($\text{C}{\text{O}}_2$) utilization provides a valuable source of carbon for the sustainable production of fuels and chemicals. The splitting of $\text{C}{\text{O}}_2$ can be performed in plasmas. It is highly endothermal, making energy efficiency an important design criterion. This paper presents a glow discharge reactor and appropriate power supply with low complexity and high efficiency, which can ignite and sustain a stable atmospheric pressure discharge of up to 20 mm length in a $\text{C}{\text{O}}_2$ atmosphere. Glow-to-arc transition, which usually prohibits glow discharge operation at high pressures, is suppressed, leading to high overall efficiency. The maximum efficiency for the driver circuit was measured as 79 %. The reactor utilizes a permanent magnetic field to achieve a large and uniform discharge volume. High power densities of up to $\text{100\hspace{0.17em}W\hspace{0.17em}}{\text{cm}}^{\text{-3}}$ and low electric field of less than $\text{100\hspace{0.17em}Vm}{\text{m}}^{\text{-1}}$ in the bulk plasma were achieved, both of which are important criteria for efficient splitting of $\text{C}{\text{O}}_2$. Efficiency measurements for the splitting of $\text{C}{\text{O}}_2$ were performed and revealed a system energy efficiency of up to 22 %. Maximum conversion reached was 20 % at 14.4 % energy efficiency. This indicates that the presented technology is competitive with other approaches. Ways to further improve the system are presented and discussed.
