In 2026, high-temperature salt energy storage is upgrading from traditional Solar Salt systems toward higher temperatures and higher energy density. Conventional nitrate commercial systems are typically limited to about 565°C, Gen3 CSP, industrial high-temperature thermal storage, and sCO₂ power generation are Molten Chloride Salt, 700°C Thermal Energy Storage, and Highemperature Salt Circulation into the phase. The U.S. DOE has listed 750°C-class molten salt pumps, valves, heat exchangers, and corrosion-resistant materials as key for Gen3 CSP. The latest breakthroughs in 202 are even more noteworthy: a research team used graphite, carbon/carbon composites, and materials such as molybdenum to build a molten salt circulation pump and storage/transport loop that operated continuously for 49 hours in the 750–950°C, validating the feasibility of ultra-high-temperature Molten Salt Pumping Infrastructure. At the same time, salt systems still face severe corrosion issues. A 2026 review pointed out that moisture, oxygen and impurity control, Ni-based Alloy compatibility, and Saltification have become the core challenges for high-temperature molten salt engineering. China's-scale CSP projects are also rapidly scaling up demand for molten salt equipment.GN's Golmud 350 MW CSP demonstration project is equipped with a 15-hour, 11,747 MWh molten salt thermal storage system; Jilin Da'an 100 MW tower CSP project adopts 565°C high-temperature molten salt and a 40 MW electric heater to achieve wind-solar-thermal-storage synergy. The Qing Gonghe million-kilowatt photovoltaic and CSP project, a million-kilowatt-class clean energy project integrating photovoltaic power generation CSP energy storage, electric-to-heat conversion, has been successfully connected to the grid. Jiangsuifa Machinery Manufacturing Co., Ltd. www.jslgpump.com has already established a portfolio covering high-temperature molten salt pumps, API 610 BB4/BB5 high-pressure multistage pumps, VS series vertical pumps, ultra-high-temperature magnetic drive pumps, and forced circulation pumps. Among these, high-temperature molten salt been designated as a key application direction on its website, and the company has a product foundation in 450°C-class leak-free magnetic drive pumps and high-temperature high-pressure process pumps. In the future, the competitive focus of Jiangsu Haifa Machinery Manufacturing Co.,.'s high-temperature molten salt pumps will upgrade from "whether it can transport" to Chloride Salt Compatibility, Hot Salt Pump Shaft Design, Thermal Shock Resistance, Low NPSH, Dry Start Protection, and Longuration Thermal Storage Reliability. Whoever can solve the material, shaft system, thermal expansion, and sealing issues above 700°C will be closer to the core equipment for next-generation long-duration thermal storage.
