Algeria aims to tap vast sunbelt to export solar energy to Europeans
Monday, August 13, 2007
ALGIERS, Algeria -- It's a vision that has long enticed energy planners: solar panels stretching out over vast swaths of the Sahara desert, soaking up sun to generate clean, green power.
Now Algeria, aware that its oil and gas riches will one day run dry, is gearing up to tap its sunshine on an industrial scale for itself and even Europe.
Work on its first plant began late last month at Hassi R'mel, 260 miles south of Algiers, the capital. The plant will be a hybrid, using both sun and natural gas to generate 150 megawatts. Of that, 25 megawatts will come from giant parabolic mirrors stretching over nearly 2 million square feet -- roughly 45 football fields.
Experts say it's the first project of its kind to combine gas and steam turbines with solar thermal input in a hybrid plant.
The plant should be ready in 2010, and the longer-term goal is to export 6,000 megawatts, about a tenth of current electricity consumption in Germany, of solar-generated power to Europe by 2020.
"Our potential in thermal solar power is four times the world's energy consumption so you can have all the ambitions you want with that," said Tewfik Hasni, managing director of New Energy Algeria, or NEAL, a company created by the Algerian government in 2002 to develop renewable energy.
The project is still at an early stage and faces daunting financial and technological obstacles. Solar power's supporters say it will take 10 years for it to become economically competitive, and while undersea cables to Sicily and Spain are planned for construction in 2010 to 2012, it isn't known who will finance them.
But as the world grows increasingly anxious about climate change and dwindling fossil fuels, ideas that once sounded like science fiction are becoming ever more plausible.
The European Union this year set a mandatory target of producing 20 percent of its energy consumption from renewable sources by 2020, and there are also big political imperatives in play.
In Algeria's case, exporting solar power through undersea cables would add flesh and bone to the idea floated by Nicolas Sarkozy, France's new president, of a "Mediterranean Union" that would bind Europe and North Africa closer together.
The Algerian program is part of a broader reassessment of green technologies by countries that owe their wealth to oil and gas. Algeria remains heavily dependent on oil and gas exports, which earned it about $54 billion last year.
"Until now all the oil-producing countries under the lead of Saudi Arabia did everything to torpedo renewable energies," said Wolfgang Palz, chairman of the independent World Council for Renewable Energy, speaking on the sidelines of an international conference on renewable energy in Algiers in June.
