Generating solar energy nonstop without sunlight

LANZHOU — In Guazhou county of Northwest China's Gansu province, a solar thermal energy storage power station can generate power for 24 hours nonstop.

Its main project has begun commissioning and will be put into operation by the end of this year, according to the China Three Gorges Corporation.

The solar thermal energy storage power station can generate electricity with or without direct sunlight, thanks to heliostats and molten salt, while achieving stable all-day power output.
