The invention discloses a method for preparing methane fuel by utilizing hydrogen storage metal to induce carbonate hydrogenation, and belongs to the technical field of clean energy and sustainable development, wherein the method comprises the steps: under an anaerobic condition, filling granular hydrogen storage metal calcium, calcium carbonate and steel balls into a ball milling tank, and then introducing hydrogen into the ball milling tank for normal-temperature reaction to prepare methane, or under an anaerobic condition, loading the granular hydrogen storage metal calcium and calcium carbonate into a heating device, then introducing hydrogen into the heating device for a heating reaction, and thus preparing methane. According to the two methods, metal and hydrogen are used as raw materials, metal hydride is generated in the reaction process, the metal hydride can reduce metal carbonate, and the obtained hydrogen-methane mixed gas does not generate other by-product gas. The method is high in yield, good i
