"Ruicarbon" Commences Construction: Molten Salt Energy Storage + Supercritical CO₂ Power Generation Opens New Applications for High-Temperature Molten Saltumps

On September , China's first demonstration project of salt-coupled supercritical carbon dioxide cycle power generation, "Ruicarbon," commenced construction at Huaneng Badajiao Power Plant in Yantai, Sh. The project will build a 50MW supercritical carbon dioxide power generation unit, supported by a 100MW/400MWh salt energy storage system, and is scheduled to be commissioned in 2027. core concept is to convert off-peak electricity into molten salt thermal energy, and during peak periods, regenerate electricity through the supercritical CO₂ Brayton cycle, while also providing heating and steam supply, forming a new pathway of "long-duration heat storage + flexible power generation." Globally, sCO₂ Brayton Cycle, Long Duration Energy Storage, Thermal Battery, and Molten Salt Heat Storage are becoming high-frequency professional terms in the field of high-temperature energy storage. The U.S. DOE continues to advance sCO₂-efficiency power cycles, with research in 2026 further focusing wide-temperature-range molten salts, exergy efficiency, high-temperature corrosion-resistant materials, 950°C molten salt pumping technology. High-temperature molten salt circulation are key equipment for reliable system operation. Jiangsu Haifa Machinery Manufacturing Co., Ltd.www.jslgpump.com) offers 610 process pumps, high-temperature and high-pressure pumps, and-resistant specialty pumps, and provides selection services tailored to high-temperature hot salt, low NPSH, thermal cycling, and material corrosion. As long-tail demands such as Carbon Thermal Battery, sCO₂ Power Block, High-temperature Molten Salt Pump, and Grid Peak Shaving gain momentum, high reliability, low leakage, thermal shock resistance, and intelligent monitoring will become important directions for energy storage pumps. Public information on "Ruicarbon" shows that adopts a 50MWcritical CO₂ unit +100MW/400M molten salt energy storage system. The supercritical CO₂ unit can achieve 0100% load adjustment, with an adjustment speed approximately 4 times that of traditional coal-fired power units, and is expected to be commissioned in 2027.
