Executive Summary

China has activated a novel dual-tower, single-turbine solar thermal power station in the Gobi Desert, marking a world-first in its design.

The facility’s innovative dual-tower configuration enhances efficiency by approximately 25 percent and reduces construction costs by requiring fewer mirrors through partially overlapping fields.

The plant stores thermal energy by melting salt at temperatures up to 570 degrees Celsius, enabling continuous electricity generation even after sunset or during overcast conditions.

The Story So Far

China has activated a novel solar thermal power station, marking a world-first with its dual-tower, single-turbine design, which aims to significantly enhance the cost-effectiveness and efficiency of large-scale renewable energy solutions. This innovative configuration improves efficiency by approximately 25% and reduces construction costs by minimizing the number of mirrors, thereby advancing China’s strategic efforts to set new global benchmarks in concentrated solar power technology.

Why This Matters

China’s activation of a novel dual-tower solar thermal power station in the Gobi Desert marks a significant advancement in renewable energy, as its reported cost-effectiveness and 25% higher efficiency compared to single-tower designs could set a new global benchmark for concentrated solar power projects. This innovation allows for continuous electricity generation, even after sunset, and underscores China’s push towards scalable, large-scale clean energy solutions, potentially influencing future international development in the sector.

Who Thinks What?

The China Three Gorges Corporation and state broadcaster CCTV view the new dual-tower, single-turbine solar thermal power station as a more cost-effective and efficient application of the technology, enhancing efficiency by about 25 percent and reducing mirror requirements.

This advancement is seen as highlighting China’s ongoing efforts to develop large-scale renewable energy solutions and potentially setting a new global benchmark for concentrated solar power projects.

China has activated a novel solar thermal power station in the Gobi Desert, marking a world-first with its dual-tower, single-turbine design. Located in Guazhou county, Gansu province, the facility is touted as a more cost-effective and efficient application of the technology, with significant potential for scalability.

Advanced Solar Thermal Design

The plant, developed by the China Three Gorges Corporation, employs nearly 27,000 mirrors to concentrate sunlight onto two 200-meter (656 feet) towers, situated approximately 1 kilometer (0.62 miles) apart. This focused energy generates intense heat, melting and storing salt at temperatures up to 570 degrees Celsius (1,058 degrees Fahrenheit).

This stored thermal energy then produces steam to power a single turbine, ensuring continuous electricity generation even after sunset or during overcast conditions. State broadcaster CCTV reported that this dual-tower configuration, with one tower optimized for morning sun and the other for afternoon, enhances efficiency by about 25 percent compared to single-tower designs.

Economic and Operational Advantages

The innovative layout also allows for partially overlapping mirror fields, reducing the overall number of mirrors required. This is a crucial cost-saving measure, as the mirrors typically represent the largest portion of construction expenses for such facilities.

Future Implications

This advancement in solar thermal technology highlights China’s ongoing efforts to develop large-scale renewable energy solutions. The design’s reported cost efficiencies and enhanced performance could set a new benchmark for concentrated solar power projects globally.
