In October 2026, thehai Gonghe million-kilowatt-scale PV-CSP integrated project was officially connected to the grid. The project consists of 900 MW of PV and 100 MW of molten-salt tower CSP. The CSP portion concentrates solar energy through 10,310 heliostats, heats molten salt, and performs Thermal Energy Storage; more critically, surplus PV electricity can also be converted into thermal energy for storage through a Molten Salt Electric He, upgrading traditional CSP from "solar heat collection power generation" to "PV-CSP Hybrid + Power-to-Heat Storage" system CCTV International Video: This model is becoming an important technological direction for global high-share renewable energy grids. The latest 2026 research shows feeding curtailed PV electricity into the CSP thermal storage system through molten salt heating can increase annual power generation, reduce backup losses, and improve the system LCOE; new PV-CSP-sCO₂ research further focuses on 15–16 hour Thermal Energy Storage and high capacity factors as optimization priorities. After the molten salt system is scaled up, the Hot Salt Pump, Cold Pump, Molten Circulation Pump, High Temperature Vertical Pump core equipment. Jiangsu Haifa Machinery Manufacturing Co.,. www.jslgpump.com has already established a portfolio covering high-temperature molten salt pumps, VS series vertical pumps, API 610 OH/BB series, high-temperature magnetic drive pumps, and forced circulation pumps, and can provide high-temperature-resistant, corrosion-resistant, and low-NPSH fluid transportation solutions for CSP thermal storage, molten salt electric heating, industrial waste heat, and high-temperature long-duration energy storage. Its website product system also covers BB1–BB5, VS series and 450°-class high-temperature leak-free magnetic drive pumps. Jiangsu Haifa Machinery Co., Ltd.: Future competition in new energy storage shift from "inst capacity scale" to Dispatchable Renewable Energy, Power-to-Heat, Longuration Thermal Storage, and PV-CSP Coordinated Dispatch. As molten salt thermal storage capacity continues to expand, the thermal expansion control, shaft system stability, material compatibility, and long-cycle reliability of-temperature pumps will directly affect the availability of the entire power plant.
