How will the technologies for the production of electricity from solar energy develop in the coming decades? Which technology is the most economical? What opportunities do the combination of multiple systems offer? A study conducted under the leadership of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) examined the future development of photovoltaic and solar thermal power plants up to 2030.
South Africa has plentiful solar energy and, at the same time, possesses a large aluminium processing industry. Researchers and industry are cooperating within the SOLAM (solar melting of aluminium in a directly radiated rotary kiln) project to develop a method by which aluminium foundries could use solar energy to melt this metal.
As a dependable technology, solar thermal power stations can play an important role in transitioning the power grid to renewable energy sources. In contrast to other renewable sources, they supply electricity on demand and can stabilise the grid.
