Optimal Dispatching and Sizing of a Power-to-Heat System with Molten-Salt Thermal Energy Storage for Industrial Heat Decarbonization

Popis výsledku v původním jazyce

Decarbonizing the industrial sector is essential for achieving climate neutrality, but it remains a complex challenge, especially for medium- and high-temperature process heat. A promising approach is the electrification of heat via Power-to-Heat (P2H) technologies, that can be further enhanced by integrating Thermal Energy Storage (TES) to improve system flexibility. This study conducts a techno-economic analysis of a P2H system combined with molten-salt TES for industrial steam generation. A mixed-integer linear programming model is developed to optimize dispatch in dynamic electricity pricing markets. Various system configurations are analyzed to identify the most cost-effective sizing strategy based on Levelized Cost of Heat. The developed model is applied to a case study of an existing plastic industry plant and the results are benchmarked against a traditional P2H solution, an electric boiler. The case study results show that the demand-side management enabled by TES can achieve operational cost savings of 0.43 M/y compared to a non-flexible P2H system in the optimally sized scenario. This paper provides new insights into the potential of medium- and high-temperature TES for optimizing industrial heat generation and supporting decarbonization of the industrial sector. Limited studies have explored P2H systems with TES for process steam supply and this work provides additional perspectives based on a real-world case study. The outcomes can be exploited by industrial plants to enhance flexibility and reduce operational costs.
