Significant progress has been made in carbon-based heat storage technology. Recently, the **Energy Group’s Research Institute (Low-Carbon Institute) and Yulin Chemical Industry carried out a new round of experiments at the Yulin Coal Chemicals and New Energy Integration Demonstration Base. The 2MW/10MWh ultra-high-temperature carbon-based solid heat storage system, independently developed by the Research Institute (Low-Carbon Institute), has seen its maximum operating temperature for heat storage increase from 900°C to 1005°C. With the system architecture remaining unchanged, the heat storage density of carbon-based heat storage devices has increased by 29%, and the system cost is expected to drop by over 20%, marking a significant breakthrough in carbon-based heat storage technology in terms of improved performance and cost reduction. Increasing the operating temperature for heat storage can effectively improve the heat storage density, thereby reducing system costs. Building on the achievement of stable operation at 900°C in the 2MW/10MWh heat storage system, and with the aim of further raising the operating temperature of this system and reducing costs, the research team carried out systematic optimization and evaluation focusing on key aspects such as temperature uniformity of the heat storage material, over-temperature control of the heating wires, and insulation design. As a result, the heat storage system was able to operate stably at 1000°C for over 168 hours, demonstrating the feasibility of high-temperature operation for carbon-based heat storage systems. This achieved a significantly higher operating temperature for heat storage, and provided critical data support for cost optimization of high-temperature carbon-based solid heat storage devices. The breakthrough in the operating temperature of ultra-high-temperature carbon-based solid heat storage devices represents an important milestone in the effort to reduce costs associated with carbon-based heat storage technology. Next, the project team will continue to work on the development of core technologies aimed at cost reduction, as well as on reliability testing, in order to provide technically sound and economically viable heat storage solutions for key application areas such as the flexibility improvement of thermal power units, clean heating in mining areas, and the integration of coal chemical industries with new energy sources.
