Cape Town – Salt melting for the purpose of generating electricity has started at the Kathu Solar Park in the Northern Cape.
A solar field will act as storage for the heat from the molten salt, to allow for later access. When solar radiation is lacking, the heat can produce steam and create electricity.
The technology used aims to satisfy demand during peak times, despite weather conditions. Thermal energy stored for approximately four hours will generate electricity for about 179 000 households.
This project can save six million tonnes of carbon dioxide in the next two decades.
The collaboration between SENER and ACCIONA Industrial aims to help the socio-economic development of the surrounding regions. It has already created about 1 400 job opportunities.
The project displays cutting-edge technology and construction and is a highlight for renewable energy production.
