Abstract

Mobile heat storage system comprising a transportable container, a thermal storage medium and a heating and / or heat transfer unit

Description

Title of the invention Mobile thermal energy storage system in container design with integrated high-temperature storage medium, inductive charging system, drying unit, hot air system and intelligent waste heat utilization Technical field The invention relates to a mobile thermal energy storage device with a solid storage medium, in particular sand, for use in industrial and building technology applications. State of the art Known heat storage systems are predominantly stationary and do not combine mobility, high-temperature capability, drying, and waste heat utilization. The use of surplus renewable energy in mobile storage systems has not yet been realized. Description of the invention The invention describes a mobile container containing a thermal storage medium, in particular sand. The system comprises an inductive heating system, a pipe system for heat transfer, an integrated or connectable utilization unit, and an intelligent control system for waste heat utilization. Energy is supplied via a plug-and-play system with a connector on the container, while the control unit remains externally attached to the energy system and can control several containers simultaneously. Solution to the task The solution utilizes a high-temperature system operating at temperatures from 300°C to 800°C. An inductively heated pipe system transfers the heat to the storage medium. The generated heat is then directly utilized via a hot air system at temperatures up to 600°C. Example of implementation The container operates in a shuttle service. It is recharged at renewable energy plants, particularly during periods of surplus electricity, such as at night or during strong winds. After recharging, the container is transported to the point of use, where it is employed for sludge drying, process heat generation, or building heating. Advantages of the invention - Utilization of surplus energy - Mobile heat supply - High efficiency through waste heat utilization - Integration of industrial processes - Scalability through multiple containers
