Against the backdrop of global climate change and energy transition, China and Arab countries are working together to build the "Green Silk Road" and are committed to promoting the development and application of clean energy. As a model of China Arab cooperation, the Dubai Maktoum Solar Park Phase IV solar thermal photovoltaic integrated power generation project not only helps the UAE optimize its energy structure and reduce carbon emissions, but also provides valuable experience for Chinese enterprises to "go global" and promotes international exchange and cooperation in green energy technology.

The project is located in the desert hinterland about 65 kilometers south of Dubai, United Arab Emirates, covering an area of 44 square kilometers, equivalent to the size of over 6000 standard football fields. The total installed capacity of the project is 950 megawatts, including 700 megawatts of solar thermal power generation units and 250 megawatts of photovoltaic power generation units. Among them, the solar thermal power generation unit adopts two mainstream solar thermal power generation technologies, tower and trough, which converge sunlight onto the collector through a mirror field composed of about 70000 solar mirrors, forming efficient solar thermal conversion. It is worth mentioning that the project has applied a mirror field wireless power and control system in the tower generator set, achieving the "wireless intelligent daily monitoring" of the sun setting mirror and significantly improving the heat collection efficiency.

In addition, the project is equipped with the world's largest molten salt thermal storage system, with a storage and power generation time of up to 15 hours. This innovative design enables solar thermal power plants to continue supplying power even in low sunlight or at night, achieving stable power generation across day and night and in adverse weather conditions, greatly improving energy efficiency.

The successful implementation of the Sino Arab cooperation solar thermal photovoltaic power generation project has made important contributions to the energy transformation and environmental protection of the UAE and even the world. The project can provide green electricity to 320000 local residents annually, reducing carbon dioxide emissions by over 1.6 million tons, effectively alleviating the local dependence on fossil fuels and promoting the development of a low-carbon economy. At the same time, the project construction period also created about 50000 job opportunities for the local area, promoting the diversified development of the local economy.
