我国光热发电加速商业化需降本增效

Core Viewpoint - The solar thermal power generation industry in China is poised for significant growth, driven by policy support, technological advancements, and the need for cost reduction to achieve competitive pricing [1][2][3]. Policy Support - Solar thermal power is recognized as a clean and renewable energy technology, with China's installed capacity reaching 838.2 MW by the end of 2024, accounting for 10.6% of the global total [2]. - The Chinese government has implemented various policies to support the industry, including a benchmark grid price of 1.15 yuan per kWh established in 2016 and the promotion of demonstration projects [2][3]. - The Energy Law, effective January 1, 2025, emphasizes the active development of solar thermal power, providing a legal framework for its growth [3]. Technological Innovation - The industry has achieved significant technological breakthroughs, with a fully autonomous supply chain and key components being domestically produced [4]. - Innovations include advanced heat collection systems, high-temperature energy storage solutions, and large-scale solar thermal power plant designs [4][5]. - The rapid development of technology is expected to substantially lower generation costs, facilitating large-scale commercial applications [4]. Economic Viability - Despite the growth potential, the current levelized cost of electricity for solar thermal power remains high, estimated at 0.8-0.9 yuan per kWh [7]. - To enhance economic viability, the industry must leverage economies of scale and establish a "technology-standard-market" ecosystem [7]. - Recommendations include improving policy support mechanisms, integrating carbon market benefits, and prioritizing advanced large-capacity projects to avoid unhealthy competition [7][8]. Collaboration and Future Directions - Industry stakeholders, including companies, research institutions, and government bodies, are encouraged to collaborate to address key scientific and engineering challenges [8]. - Increased investment in research and development is essential for advancing high-capacity and intelligent solar thermal technologies [8].
