A large concentrated solar power (CSP) project in China has selected Sulzer, a global fluid technology company, to supply both the hot and cold molten salt pumps for the plant. The planned 100-MW solar project will feature technology designed to provide electricity from solar energy 24 hours a day. Molten salts have been used in the nuclear industry for nearly 70 years, and Sulzer has been involved in the design and manufacture of the pumps that transport the high-temperature fluids around the cooling circuits. The company was involved in pioneering the technology for use in the solar industry more than 15 years ago, allowing thermal energy to be stored overnight.
