South Africa unveils innovative solar tower powering round-the-clock

South Africa has launched a groundbreaking energy project – a solar tower using molten salt technology. This innovative energy storage method allows electricity supply around the clock, even after sunset.

Renewable energy continuously evolves, and South Africa, by introducing the Redstone solar tower, once again demonstrates that it is a leader in innovation in this field. The project, which uses concentrated solar power (CSP) technology, delivers up to 480 GWh of clean energy annually, stabilizing the national energy system and reducing CO2 emissions. A key element of this power plant is heat storage in molten salt, allowing for energy generation for 12 hours a day – even after sunset.

South Africa has taken a significant step towards the future by launching a solar tower with a capacity of 100 MW. This innovative project provides clean energy and highlights the region's commitment to developing renewable energy sources.

The Redstone solar tower, built in the Northern Cape province, stands out for its use of CSP technology. This technology enables the generation of electricity from solar energy all day and night, giving South Africa a stable source of energy, reducing CO2 emissions, and lessening dependence on fossil fuels.

The heart of this solar tower's operation is technology based on precisely positioned mirrors, known as heliostats, designed to focus sunlight on a heat receiver at the top of the tower. In this case, the key element is the use of molten salt, which stores energy in heat.

Thanks to this, the solar tower can supply energy even after sunset, ensuring continuity in electricity production for 12 hours a day. This innovative solution makes Redstone a groundbreaking project on a global scale, and the technology could become a model for other countries.
