The
Moroccan city of Ouarzazate is used to big productions. On the edge of
the Sahara desert and the centre of the north African country’s
“Ouallywood” film industry it has played host to big-budget location
shots in Lawrence of Arabia, The Mummy, The Living Daylights and even
Game of Thrones.
Now the trading city, nicknamed the “door of the desert”, is the
centre for another blockbuster – a complex of four linked solar
mega-plants that, alongside hydro and wind, will help provide nearly
half of Morocco’s electricity from renewables by 2020 with, it is hoped,
some spare to export to Europe. The project is a key plank in Morocco’s
ambitions to use its untapped deserts to become a global solar
superpower.
When the full complex is complete, it will be the largest concentrated solar power (CSP) plant
in the world , and the first phase, called Noor 1, will go live next
month. The mirror technology it uses is less widespread and more
expensive than the photovoltaic panels that are now familiar on roofs
the world over, but it will have the advantage of being able to continue
producing power even after the sun goes down.
The potential for solar power from the desert has been known for
decades. In the days after the Chernobyl nuclear accident in 1986 the
German particle physicist Gerhard Knies, calculated that the world’s
deserts receive enough energy in a few hours to provide for humanity’s power needs for a whole year. The challenge though, has been capturing that energy and transporting it to the population centres where it is required.
As engineers put the finishing touches to Noor 1, its 500,000
crescent-shaped solar mirrors glitter across the desert skyline. The 800
rows follow the sun as it tracks across the heavens, whirring quietly every few minutes as their shadows slip further east.
When they are finished, the four plants at Ouarzazate will occupy a space as big as Morocco’s capital city, Rabat, and generate 580MW of electricity, enough to power a million homes. Noor 1 itself has a generating capacity of 160MW.
Morocco’s environment minister, Hakima el-Haite, believes that solar
energy could have the same impact on the region this century that oil
production had in the last. But the $9bn (£6bn) project to make her
country’s deserts boom was triggered by more immediate concerns, she
said.
