Abstract

A fuel preparation reaction system includes: an electrolytic hydrogen production equipment connected to a power supply device of a power generation plant and configured to produce hydrogen through electrolysis with surplus power from peak regulation of the power generation plant as a power supply; a fuel preparation reaction equipment configured to produce fuel with hydrogen and carbon dioxide; an input end of the fuel preparation reaction equipment is connected to a hydrogen output pipe of an electrolytic hydrogen production device, while another input end is connected to a supply source of carbon dioxide, a fuel output port being connected to a fuel collection device or a fuel utilization device. The system can directly consume peak-regulation power from a power plant, thereby improving power grid balance and differences between peaks and valleys, while achieving phase-changed storage of electric energy and effective usage of energy.
