Powering change
The Gemasolar solar power plant in Andalucia, with its
140-metre high concrete tower and a field containing 2,650
heliostats, is powering change. What makes this power
plant revolutionary is not the heliostats or the central receiver,
but the way in which energy is stored – flowing through the
receiver and filling the tanks, which are 14 metres high and
36 metres wide, located at the base of the tower.
Until now, solar technologies were restricted by the fact that
they normally only generate electricity during sunlight hours.
Gemasolar is the first large-scale solar power plant to use
molten salt as a heat storage system. When heated to
565 degrees Celsius, it can provide electricity for 15 hours.
Gemasolar can therefore supply power round the clock
and not just when the sun is shining.
The Spanish solar power plant is just one example of the intel-
ligent use of energy. Industry initiatives such as Green Carbody
or Blue Competence are setting the standard for greater
energy efficiency worldwide.
