As the demand for global climate change intensifies and energy transformation grows, solar energy becomes a clean, low-carbon, renewable resource which has emerged as a vital choice for energy transition in many countries. In particular, solar thermal power generation technology is gaining attention due to its efficient thermal energy conversion and relatively stable power generation characteristics. This article analyzes the strategic plan for the high-quality development of China's solar thermal industry, driven by the "dual carbon" goals and energy transformation initiatives.
First, this article provided an overview of the main solar thermal development technologies in China and reviewed the historical progression of solar thermal technology within the country, highlighting significant advancements in technological innovation, project construction, and policy support in recent years. Next, we analyzed current solar thermal projects connected to the grid in China, examining aspects such as investment costs, operational power generation and economic viability, as well as projects that were under construction or proposed. Finally, We also addressed the challenges faced in promoting and applying solar thermal technology in China, including technical challenges related to system efficiency, integration and heat storage; High construction and operational costs that affected project economics; Market challenges arising from competition and lengthy project approval cycles; Policy support issues such as regulatory instability and gaps; Environmental challenges including land use, water consumption, and social acceptance. To overcome these challenges, this paper offered several development recommendations.
The high-quality development of the solar thermal industry necessitates comprehensive support from the entire sector. The government should increase investment in research and development of solar thermal technology, enhance core technological innovation, and optimize the assessment and planning of solar thermal resources. Improving resource utilization efficiency and managing large-scale production costs can also help reduce operational expenses and enhance economic viability. Furthermore, it is essential to refine relevant policies and market mechanisms for solar thermal power generation, providing additional financial incentives and support. Expanding into new markets and regions, fostering international cooperation, and promoting the implementation of solar thermal projects are crucial steps. Finally, strengthening social communication and environmental protection is vital.
By analyzing the current status, challenges, and development recommendations for solar thermal power generation in China, this article offers systematic theoretical support and practical guidance for industry advancement. The aim is to facilitate the maturation and application of solar thermal technology. Ultimately, the development of China's solar thermal technology is significant not only for national energy security and environmental protection but also plays a key role in the global energy transition and climate change response.
