Energy storage is needed for adjusting fluctuating renewable energies to the actual energy demand. A liquid organic hydrogen carrier (LOHC) system is examined for its suitability as a storage system for industrial applications. Integration of the LOHC system, e.g., into a cement plant allows for optimized utilization of waste heat. The exhaust heat from the cement plant can increase the efficiency of the storage system. The effectiveness of the LOHC system can be elevated by twelve percentage points. The working electricity costs of the cement plant can be significantly reduced by adding a LOHC storage system.
