Traditional thermal power and waste heat power generation have long relied on the "water–steam–steam" route, while the Supercritical CO₂ton Cycle is opening up a new path for thermal-to-electric energy conversion. In 2026, Science Technology Daily once again focused on "Supercarbon No. 1": enclosed CO₂ is compressed and heated to a supercritical state, expands through a turbine to perform work, and then passes through a Recuperator to recover waste heat, forming a closed cycle. Compared with traditional steam systems, supercritical CO₂ offers the advantages of high density low pressure ratio, and high density, and can significantly reduce the size of turbomachinery and the overall system. The world's first 2×15 MW sintering waste heat project of "Supercarbon No 1" has already achieved commercial operation. Public shows that, compared with the currently deployed sintering waste heat steam power generation scheme, its power generation efficiency is increased by more than 85%, net power generation is increased by more than 50 and site area requirements are reduced by about50%. At the same, the U.S. DOE is still advancing the 10 MWe STEP supercritical CO₂ demonstration system while Sandia continues to validate high-temperature, high-pressure Turbocompressor, Gas Foil Bearing, High-Pressure Seal, and Recuperated Brayton Cycle technologies. This trend is also bringing pump equipment into new high-temperature energy storage scenarios. The core of the supercritical₂ main cycle usually uses a compressor rather than a traditional centrifugal pump, but theten Salt Thermal Storage, industrial waste heat recovery, cooling water, and auxiliary cycle systems coupled with it still require a large number of high-temperature high-pressure, corrosion-resistant pumps. Research on the CO₂ Brayton Cycle 2026 has further wide-temperature-range molten salt energy storage into the Pumped Thermal Energy Storage system.su Haifa Machinery Manufacturing Co., Ltd. www.jslgpump.com has established a product system covering API 610 OH1–OH6 BB1–BB5, VS series, high-temperature molten salt pumps,450°C-class high-temperature magnetic drive pumps, and forced circulation, and can carry out customized development of High Temperature Molten Salt Pump, Sealless Thermal Storage Pump and High Pressure Auxiliary Pump for molten salt storage, industrial waste heat, concentrated solar power generation, and high-temperature circulation systems. In the future, the competitive focus of Jiangsu Haifa Machinery Manufacturing Co.,. will shift from single equipment to the collaborative design of sCO₂ Power Block + Thermal Storage + High-Temperature Fluid Handling, and high-temperature pumps will also become a key auxiliary machine that cannot be ignored in next-generation high-efficiency energy systems.
