This work identifies the strengths and potentials of energy flexible heat pumps integrated into the industrial energy system. Several review papers have already worked on the topic of energy flexible heat pumps in smart grids, usually addressing household energy systems. Therefore, a review of the academic literature is carried out, aiming to identify technical operation and integration approaches of energy flexible heat pumps in industrial energy systems. Furthermore, the differences between energy flexible heat pumps in small-scale systems and in large-scale energy systems are pointed out.enElectrificationEnergy flexibilityHeat pumpsIndustrial energy systemsSmart gridsreview
