A method for fossil fuel free heating in a cement manufacturing plant, the method comprising: obtaining a product by processing a raw material at a process equipment, wherein heat required for processing the raw material is derived from a gas used as a heating medium, wherein the gas is heated electrically to a predefined temperature, wherein the heat from the gas is transferred directly to the raw material through direct contact, wherein the gas is chemically inactive or participating in the reactions during processing of the raw material, and wherein the gas is at least one of: (i) involved in the processing of the raw material as a reactant and/or a byproduct, and (ii) an externally introduced stable gas, or a gas mixture thereof; heating the gas to the predefined temperature at a plurality of electric gas heaters (104A-N), powered with electricity source, where preheating of the gas is performed at a heat recovery unit, wherein the heat released by the heat recovery unit during cooling of the product exiting the processing equipment is utilized to raise temperature of the gas, and wherein a heating medium flow design loop comprising of the plurality of electric gas heaters reutilizes the heat carrying capacity of the gas by recirculation and eliminates need for storing heat energy from the gas; cleaning the gas before entering the plurality of electric gas heaters (104A-N) at a plurality of gas cleaning units (114A-N); recovering the gas, at an optional gas recovery unit, exiting the processing equipment followed by a gas separator to separate out solid particles before venting out non-harmful gases to the environment; and storing the gas exiting the gas separator at a gas storage unit, wherein the stored gas is recirculated as a heating medium in the heating medium flow design loop and excess gas is forwarded for sequestration for longer term storage or utilization. obtaining a product by processing a raw material at a process equipment, wherein heat required for processing the raw material is derived from a gas used as a heating medium, wherein the gas is heated electrically to a predefined temperature, wherein the heat from the gas is transferred directly to the raw material through direct contact, wherein the gas is chemically inactive or participating in the reactions during processing of the raw material, and wherein the gas is at least one of: (i) involved in the processing of the raw material as a reactant and/or a byproduct, and (ii) an externally introduced stable gas, or a gas mixture thereof; heating the gas to the predefined temperature at a plurality of electric gas heaters (104A-N), powered with electricity source, where preheating of the gas is performed at a heat recovery unit, wherein the heat released by the heat recovery unit during cooling of the product exiting the processing equipment is utilized to raise temperature of the gas, and wherein a heating medium flow design loop comprising of the plurality of electric gas heaters reutilizes the heat carrying capacity of the gas by recirculation and eliminates need for storing heat energy from the gas; cleaning the gas before entering the plurality of electric gas heaters (104A-N) at a plurality of gas cleaning units (114A-N); recovering the gas, at an optional gas recovery unit, exiting the processing equipment followed by a gas separator to separate out solid particles before venting out non-harmful gases to the environment; and storing the gas exiting the gas separator at a gas storage unit, wherein the stored gas is recirculated as a heating medium in the heating medium flow design loop and excess gas is forwarded for sequestration for longer term storage or utilization.
