我国光热发电需以四大创新推动规模化发展

Core Viewpoint - The solar thermal power generation industry in China is entering a new stage of large-scale development driven by policy and technology, emphasizing the need for innovation in management, models, and systems to ensure sustainable and high-quality growth [1][2]. Industry Development - Solar thermal power technology integrates solar thermal conversion, large-scale heat storage, and grid synchronization, providing significant advantages as a renewable energy source [2]. - The industry is transitioning from a commercial demonstration phase to large-scale development, supported by favorable policies and market conditions [2]. - As of the end of 2024, China's cumulative installed capacity of solar thermal power reached 838.2 MW, accounting for 10.6% of the global total [3]. Policy Support - The National Energy Administration initiated the first batch of 20 solar thermal power demonstration projects in 2016, with an installed capacity of 1.349 million kW, marking the start of commercial development [2]. - A notification issued in April 2023 aims for an annual new installed capacity of approximately 3 million kW during the 14th Five-Year Plan period [2]. - The Energy Law, effective January 1, 2025, explicitly promotes the development of solar thermal power, highlighting its importance in national energy strategy [2]. Technological Advancements - The solar thermal power industry has seen significant technological innovations, with a domestic equipment localization rate exceeding 98% [4]. - Recent developments include the successful creation of a large aperture molten salt medium trough collector system and the world's first supercritical carbon dioxide solar thermal power generation unit [4]. - The industry now covers all aspects of the supply chain, from raw materials to core equipment with independent intellectual property rights [4]. Cost Reduction - The cost of solar thermal power generation has decreased to 0.55 yuan per kWh, down from 1.15 yuan per kWh for the first demonstration projects, indicating a significant reduction in costs [5]. - Continued technological innovation and large-scale development are expected to further lower costs, making solar thermal power a cheap and stable green energy source [5]. Challenges and Innovations - The industry faces challenges such as high costs and efficiency improvements, necessitating innovative solutions in technology, management, and policy [6]. - Recommendations include enhancing research on efficient heat collection and long-duration heat storage technologies, utilizing digital technologies for intelligent management, and developing integrated projects with other renewable energy sources [6]. - A supportive policy ecosystem is essential, including a combination of capacity pricing and peak compensation mechanisms for solar thermal power projects [6].
