摘要：

In this paper a new 'fuel', fayalite Fe2SiO4, is proposed tentatively and a new concept involving the convergence of a power plant and its fuel source is described. The CO2 from the power plant would be injected underground where it would be reduced to methane. The methane would then serve as the 'derived fuel' of the power plant having been produced by the reaction of fayalite with the CO2. One of the possible chemical reactions of CO2 with rock is indicated, along with properties of the mineral fayalite. Calculations of the Gibbs free energy and enthalpy show that the reaction of carbon dioxide with fayalite is exothermic and might be self-sustaining.
