According to Dongfang Boiler Co., Ltd., a subsidiary of Dongfang Electric Corporation (referred to as Dongfang Boiler), in August 2024, China’s first supercritical carbon dioxide photothermal power generation unit was developed successfully in Yanqing, Beijing. All parameters of this unit, such as its power generation capacity and thermal conversion efficiency, met the requirements set for the project. This project overcame challenges related to the design and manufacturing of key components such as solar-driven high-temperature solid particle heat absorption systems, fluidized-bed solid particle/CO2 heat exchange systems, and 200-kilowatt-class supercritical CO2 power generation units, and was the first in the world to achieve the operation of a supercritical CO2 solar thermal power generation system. The fluidized bed solid particle/carbon dioxide heat exchanger developed by Dongfang Boiler for this project enables efficient and reliable heating of solid particles by supercritical carbon dioxide, achieving the designed output levels; this represents a new breakthrough by Dongfang Boiler in the field of high-temperature solid particle storage, heat exchange, and photothermal technologies characterized by low cost, high efficiency, and high flexibility. The next generation of photothermal and solid particle heat storage technologies requires higher heat storage temperatures, greater mass heat storage density, and lower costs in order to improve the heat/electricity conversion efficiency, reduce system investment, and enhance the economic viability of these solutions. Solid particle heat storage is one of the most promising solutions for next-generation photothermal and high-temperature heat storage technologies. As a heat storage medium, solid particles possess advantages such as high operating temperature, high mass heat storage density, low cost, and easy availability. However, they also have drawbacks including high specific gravity and poor heat transfer and fluidity properties. Therefore, solid particle heat storage and exchange systems use solid particle heat exchangers and solid particle/working fluid heat exchange devices as their key components.
