U.S. Promotes R&D of New Generation Concentrating Solar Power System

      The U.S. Department of Energy announced on the 15th that it will invest 72 million U.S. dollars in the development of a new generation of high-temperature concentrating solar power systems.   
      Concentrating solar power is another technology that converts solar energy into electricity in addition to photovoltaic technology. The technology uses a mirror to focus sunlight and convert it into heat, which drives the turbine to run. Since the heat converted by sunlight can be stored and converted to electricity when needed, the technology can guarantee continuous power supply at night or on rainy days. The United States is one of the countries with a better application of concentrating solar power generation technology in the world. The Ministry of Energy announced in September last year that it invested US$62 million to increase the research and development of concentrating solar power generation technology.
      The operating temperature of the thermal energy system is a key factor in controlling the cost of concentrating solar power generation. At present, the operating temperature of the best commercial concentrating solar power generation technology thermal energy system in the United States reaches 565°C. The third-generation high-temperature concentrating solar power generation project (Gen3 CSP) launched by the US Department of Energy aims to push the operating temperature of the thermal energy system above 700°C, which will effectively increase the power generation efficiency and reduce the cost of power generation.   According to the Ministry of Energy, if the project is successful, it will reduce the cost per kWh of electricity generated by concentrating solar power plants by about 2 cents, which is equivalent to the 2030 target cost set by the Department of Energy for US concentrating solar power plants. 50% of electricity is 5 cents).


      Currently, the Department of Energy has selected three research units from Breton Energy, the National Renewable Energy Laboratory, and Sandia National Laboratories to participate in the project. They will compete around the integrated design of high-temperature components and high-temperature thermal energy storage systems. .
      Daniel Simmons, the deputy assistant secretary of the Department of Energy, stated that the United States is a world leader in high-temperature concentrating solar power research. The new project will help promote the development of new technologies for high-temperature concentrating solar power generation and maintain the United States in this field. leadership.
