Providing an implementable renewable fuel gas plant processes with management of greenhouse gases with minimal changes to existing plant set ups is a technical challenge to be addressed. Embodiments herein provide a system for renewable fuel gas generation and utilization in industrial plants with carbon dioxide as heat carrier. The system design integrates renewable fuel gas (H2) which is generated within the system and utilized to meet the thermal energy requirements of the production process. CO2 produced as byproduct of calcination in a process equipment, such as during calcination in cement plant is used as a heat-transferring medium to heat the H2. Further, the system provides recycling of the generated byproducts by separating the exhaust gases, comprised of CO2 and H2O. The H2O is recycled to generate H2 via electrolysis. The separated CO2 again serves as a heat-transferring medium, while the excess CO2 is sequestrated.
