Huang Wenbo said that by the end of 2022, the installed capacity of renewable energy power generation in China has historically exceeded that of coal power generation. The construction of new energy system and new power systems has brought new opportunities for the development of the CSP industry. The State Council's Action Plan for Carbon Peak before 2030 clearly states that: actively develop solar thermal power generation and promote the establishment of a comprehensive renewable energy power generation base with solar thermal power generation, photovoltaic power generation and wind power complementary regulation. We will accelerate the construction of new power system. This points out the direction for the development of solar thermal power generation industry. In the past 2022, with the rapid development of about 30 CSP projects in comprehensive renewable energy power generation bases with a total installed capacity of about 3.3 million kilowatts, the solar thermal power generation industry ushered in a new upsurge of development and also brought new challenges. For example, how to give full play to the comprehensive advantages of the long-cycle, large-capacity, high-security and low-cost heat storage system equipped in the CSP plants to better meet the needs of building a new power system? How to tap the greater potential value of solar thermal power generation technology in the context of electricity market trading? These problems need to be better solved through collective thinking and concerted efforts. As the executive vice-chairman of the China Solar Thermal Alllianceand the co-sponsor of the conference, Shouhang Hi-Tech actively participated in the exchange and cooperation of the industry innovation platform, and also hoped to establish closer contact and more accurate interaction with more industry experts and leaders, wholeheartedly serve the overall situation of CSP industry, and play the responsibility and responsibility of enterprises under the "double carbon" goal.

The supercritical carbon dioxide solar thermal power generation system supported by the national key research and development plan will be completed in Yanqing, Beijing, in the first half year of 2024. China has taken the lead in the world in the fourth generation of CSP technology.
The development of the solar thermal power industry cannot be separated from the support of science and technology, let alone the joint efforts and active participation of our colleagues. In fact, the number of participants in the industry conference also reflects the development of the industry. In 2007, there were less than 60 participants in the first conference. Today, the conference was full of guests, with more than 750 registered participants, and more than 680 on-site participants. The solar thermal power industry is ushering in a new chapter of large-scale development.

The conference lasted for 2.5 days, and had nearly 60 technical reports for discussion, 16 exhibitions, plus the visit to the DCTC and Shouhang’s CSP plants in Dnhuang.
As the only high-quality power source capable of generating electricity continuously 24 hours a day and giving full play to the role of coal-fired power generation, the advantages and value of solar thermal power generation have gradually been highly recognized by the national level, investment enterprises and the power industry. This conference not only set a new record in the number of participants, but also expanded the scope of participants from equipment and technology suppliers to state-owned enterprises and central enterprises. The "Fourteenth Five-Year Plan for Renewable Energy" jointly issued by the National Development and Reform Commission, the National Energy Administration, the Ministry of Finance and other nine ministries and commissions proposed that Qinghai, Gansu, Xinjiang, Inner Mongolia, Jilin and other areas of high-quality resources should give full play to the energy storage regulation capacity and system support capacity of solar thermal power generation, build long-term thermal storage solar thermal power generation projects, and promote the integrated construction and operation of solar thermal power generation, wind power and photovoltaic power generation bases, improve the stability and reliability of new energy power generation. While solar thermal power generation ushers in new development opportunities, it also needs the joint efforts of the whole industry to increase scientific and technological innovation, reduce costs, and promote the prosperity and development of solar thermal power generation industry.
