经济日报丨能源转型迎来“光热时刻”

Core Viewpoint - The article emphasizes the importance of solar thermal power as a key technology in China's energy transition, aiming for a total installed capacity of approximately 15 million kilowatts by 2030, with electricity costs comparable to coal power [2][3]. Group 1: Importance of Solar Thermal Power - Solar thermal power acts as a stabilizer and regulator for the power grid, providing continuous and stable electricity even during nighttime or cloudy days, which is crucial as wind and solar power installations increase [3]. - The development of solar thermal power is expected to drive advancements in high-end manufacturing sectors, including precision machinery and high-temperature materials, enhancing China's competitiveness in the global renewable energy supply chain [3]. Group 2: Current Status and Challenges - China has successfully mastered mainstream solar thermal technologies, with the cost of power generation dropping to around 0.6 yuan per kilowatt-hour and construction costs decreasing from approximately 30,000 yuan per kilowatt to 15,000 yuan over the past decade [3][4]. - Despite its potential, solar thermal power faces challenges such as high initial investment and reliance on imported technology, which contribute to elevated project costs [4]. Group 3: Policy Measures and Solutions - Policies aim to reduce costs through large-scale deployment and the establishment of solar thermal power as a primary source in new energy stations, potentially increasing annual installed capacity by nearly 3 million kilowatts [4]. - The government encourages the localization of key equipment and optimization of performance to reduce import dependency and enhance operational efficiency [4]. Group 4: Future Trends - By 2030, solar thermal power is expected to integrate with other energy sources, such as photovoltaic and wind power, to provide stable energy solutions [5]. - The industry will diversify its technology routes and focus on efficiency improvements, moving from merely increasing installed capacity to enhancing power generation efficiency and reducing costs [6]. - Solar thermal power companies will evolve into comprehensive energy service providers, offering not just electricity but also peak regulation and backup services, becoming essential components of the new energy system [6].
