1. A reforming method of reforming a hydrocarbon to obtain hydrogen, comprising:
reforming a hydrocarbon with steam plasma to generate a first synthetic gas, which comprises hydrogen and carbon dioxide, from the hydrocarbon;
cooling the first synthetic gas to a predetermined temperature, removing water vapor included in the first synthetic gas, and separating hydrogen from the first synthetic gas;
reforming the first synthetic gas, from which hydrogen is separated, and a hydrocarbon with steam plasma to generate hydrogen, and generating a second synthetic gas in which carbon dioxide is decreased; and
cooling the second synthetic gas to a predetermined temperature, removing water vapor included in the second synthetic gas, and separating hydrogen from the second synthetic gas.
