1. A plant for producing methane, comprising:
an electric energy source;
a water electrolyser supplied with electrical energy from the electric energy source, suitable for producing hydrogen in gas form;
an atmospheric carbon dioxide capture device suitable for producing carbon dioxide and water;
a methanation reactor fitted with an inlet for hydrogen from the electrolyser, fitted with an inlet for water and carbon dioxide from the atmospheric carbon dioxide capture device, and suitable for producing methane; and
solar collectors and a means for heat transfer from the solar collectors to the carbon dioxide capture device.
