多技术路线并行 “超级镜子”在这里变身

Core Viewpoint - The article highlights the innovative use of mirrors, specifically "heliostats," in solar thermal power generation, showcasing their role in converting solar energy into clean electricity. Group 1: Technology and Mechanism - The "heliostat" mirrors track the sun's trajectory and reflect solar energy to a central receiver, enabling efficient energy capture [3][7]. - The reflected solar energy heats liquid salt in a receiver tower, which then generates steam to drive turbines for electricity production [9][11]. - This solar thermal power generation method is characterized by its efficiency, environmental benefits, and ability to store heat energy for continued power generation even after sunset [14]. Group 2: Production and Impact - The solar thermal project in Gansu Province can produce approximately 1.45 billion kilowatt-hours of clean electricity annually, saving around 480,000 tons of standard coal [12]. - The total installed capacity for solar thermal power in Gansu has reached 620,000 kilowatts, with various technologies such as tower, trough, and Fresnel systems coexisting [16]. - As China's new energy system develops, the role of solar thermal power as a stabilizer in the electricity system is expected to become increasingly significant, supporting the transition to greener energy structures [17].
