High dependency on fossil fuel in the current industrial energy systems has been bringing serious awareness on the environment. Paris Agreement also supports the necessity of imperative innovation for industrial energy system. Reduction of the use of fossil fuel can be implemented as decarbonization. Among several decarbonization methods, electrification is applicable for various industry with a robust basis of technology development, which is also impacted by the wide spread of electricity generated with renewable resources. Therefore, this study aims at investigating the feasibility of electrification methods with case study to compare with fossil-fuel-based energy system.

First, electrification options are examined for their applicability. It is followed by analysis of energy system, with which Heat Integration is considered to fulfill maximum energy recovery. Grand Composite Curve enables the processes to be matched with proper utilities leading to efficient utilization of electricity, which is applied to the case study of industrial processes. The feasibility of industrial electrification for decarbonization is examined with the evaluation of energy cost and its impact on the energy system, particularly with the comparison between fossil fuel and renewable energy.
