Abstract
An energy utilization system includes a circulation circuit. The circulation circuit includes a pump, a heating section, an electrolytic reduction apparatus, and a thermal energy recovery section. The pump receives a heating medium and outputs the heating medium. The heating section heats the heating medium by using renewable energy or energy obtained from waste heat. The electrolytic reduction apparatus heats an electrolytic solution with heat from the heating medium. The circulation circuit circulates the heating medium. A method for producing a carbon-containing material includes heating a heating medium circulating in a circulation circuit by using renewable energy or energy obtained from waste heat, and performing electrolytic reduction by heating an electrolytic solution with heat from the heating medium that has been heated.
