About Royal Tech

Changzhou Royal Tech CSP Limited, established in 2009, operates as a specialized developer and manufacturer in the concentrated solar power (CSP) sector, providing comprehensive solutions for solar thermal power generation. The company’s business model encompasses the entire value chain, including research and development, manufacturing of core components, system integration, and project development. Royal Tech generates revenue by producing and selling key CSP equipment, such as high-temperature vacuum receiver tubes and parabolic trough collectors, and by delivering turnkey solutions for both large-scale power plants and smaller industrial process heat and cooling applications.

The firm's primary product is its proprietary high-temperature vacuum receiver tube, a critical component in CSP systems that absorbs concentrated sunlight to heat a transfer fluid. These tubes are designed to operate at high temperatures, with some models capable of functioning beyond 565°C, making them suitable for various heat transfer fluids, including molten salt. Royal Tech has developed advanced coatings to enhance solar absorptance and reduce heat loss, which improves the overall efficiency of the power generation process. The company offers solutions for two main types of CSP systems: parabolic trough collectors, which are ideal for large, grid-scale power plants, and Linear Fresnel collectors, often deployed for rooftop industrial heat and cooling needs in partnership with Germany's Industrial Solar GmbH.

A significant milestone for Royal Tech was the development and investment in the Urat 100MW Trough CSP National Demonstration Project in Inner Mongolia. This plant, which utilizes Royal Tech's domestically produced equipment and a 1,000 MWh molten salt storage system, became fully operational in 2021 and has demonstrated high operational performance and reliability. The success of this project showcases the company's capability in integrating large-scale solar fields and managing complex CSP plant operations. The company has received multiple rounds of funding, including a significant investment in 2022 led by the state-backed GuoKai Manufacturing Transformation and Upgrading Fund, to expand its manufacturing capacity and advance its technology. Royal Tech has established a global presence, exporting its receiver tubes to international projects, including a key European demonstration project in Évora, Portugal, led by the German Aerospace Center (DLR).
