It's decision day on a chain of solar generators across the desert that could supply a quarter of Europe's power
Tony Paterson, The Independent 12 Jul 09;
The world's most ambitious green energy project is about to take shape. It is a plan for a chain of mammoth sun-powered energy plants in the deserts of North Africa to supply power to Europe's homes and factories by the end of the next decade.
In a few days' time a consortium of 20 German firms will meet in Munich to hammer out plans for funding the giant €400bn (£343bn) project, named Desertec. The scheme is being backed by Chancellor Angela Merkel's government and several German industry household names including Siemens, Deutsche Bank, and the energy companies RWE and E.ON. The Munich meeting will also involve Italian and Spanish energy concerns, as well as representatives from the Arab League and the Club of Rome think-tank.
Energy experts have calculated that Desertec could meet at least 15 per cent of Europe's needs, and be up and running by 2019. By 2050, they estimate the contribution could be between 20 and 25 per cent. Although no host countries have been named, Desertec envisages a string of solar-thermal plants across North Africa's desert. The plants would use mirrors to focus the sun's rays, which would be used to heat water to power steam turbines. The process is cheaper and more efficient than the usual form of solar power, which uses photovoltaic cells to convert the sun's rays into electricity.
The project also envisages setting up a new super grid of high-voltage transmission lines from the Mahgreb desert to Europe. Hans Müller-Steinhagen, of German Aerospace, has researched the project for the German government. He said that although the idea behind the scheme had been around for several years, investors had been deterred by the high costs of setting up the infrastructure.
Professor Müller-Steinhagen said that similar projects have been operating in the American West for years, but these had failed to gain the appropriate recognition. "Solar thermal power plants were built in California and Nevada, but people lost interest in them because fossil fuels became unbeatably cheap," he said.
Until now, projects of Desertec's scale have failed to get off the ground because of the huge problems involved in delivering electricity to consumers hundreds of miles away. The main stumbling block is that the further electricity is transported, the more is lost. However, Siemens claims that it has come up with a solution. Alfons Benziger, a spokesman for the engineering giant which has been involved in the construction of major hydro-power plants in India and China, said: "We have developed so-called high-voltage direct current energy transmission. This can transport energy over long distances without heavy losses. We use the process at the power plants in India and China."
Andree Böhling, an energy expert for Greenpeace Germany, has heaped praise on Desertec: "The initiative is one of the most intelligent answers to the world's environmental and industrial problems," he said. Munich Re, meanwhile, which insures major insurance companies across the globe, was persuaded to invest in the project after seeing a steady rise in the number of claims the company had to meet as a result of climate-change-induced damage.
Yet Germany's largest solar energy company, SolarWorld, argues that North Africa is too risky a location. "Building solar power plants in politically unstable countries opens you to the same kind of dependency as the situation with oil," said Frank Asbeck, the firm's managing director.
Other critics claim that by singling out comparatively poor North African countries as a location for a sophisticated European solar energy project amounts to a form of "solar imperialism". Lars Josefsson, the head of the Swedish energy giant Vattenfall, has also rejected the idea because of a potential risk of terrorist attacks. However Desertec supporters, including the German conservative politician Friedbert Pflüger, argue that a far greater threat is posed by the prospect of nuclear power plants being subjected to such attacks. He points out that a number of nuclear reactors are scheduled to be built in North Africa – Egypt alone plans to build five. Mr Pflüger claims that the risk of politically motivated Russian-style energy stoppages by host countries could be avoided if the solar grid has enough supply channels.
But he warns that politics is likely to be the main stumbling block. "It's not Europe that will decide whether the desert can be used as an energy resource, but the countries of North Africa," he said last week. "So far these countries have either not been involved in the dialogue at all or only at a very limited level."
400-billion-euro plan to pump African solar power to Europe

MUNICH, Germany (AFP) – Twelve European companies launched a 400-billion-euro (560-billion-dollar) initiative Monday to plant huge solar farms in Africa and the Middle East to produce energy for Europe.
The consortium says the massive proposal could provide up to 15 percent of Europe's electricity needs by 2050.
Engineering giants ABB and Siemens, energy groups E.ON and RWE and financial institutions Deutsche Bank and Munich Re are among the companies which signed a protocol in Munich.
"Today we have taken a step forward" towards the project's realisation, said Nikolaus von Bomhard, head of the reinsurance giant Munich Re, which hosted the signing.
The Desertec Industrial Initiative (DII) would build solar-power generators from Morocco to Saudi Arabia and pump electricity to Europe via undesea cables.
It would also provide a "substantial portion of the power needs of the producer countries," the Desertec foundation said in a statement, and transform sea water into drinking and irrigation water for local populations.
Munich Re board member Torsten Jeworrek said the European companies involved had pledged to work "as equals in a sincere and fair" manner with producer countries.
For Jordan's Prince Hassan ibn Talal: "The partnerships that will be formed across the regions as a result of the Desertec project will open a new chapter in relations between the people of the European Union, West Asia and North Africa."
Many details still have to be worked out however, including where to install the plants, when the power would come on and how much it would cost, potential profits, political stability in some areas and of course, financing.
Renewable energy analyst Sebastaian Zank at West LB bank, which is not involved in the project, said it might succeed but only "in the very, very long term.
"As long as there are no transmission networks between these two continents this is more or less a nice future fantasy," Zank told AFP.
Under the protocol, a Desertec study office to be established by October will have three years to elaborate plans to create the network of solar farms and transmission networks and find the funds.
Representatives of the Arab League and the Egyptian energy ministry also attended the protocol's signing.
Other companies invoved are the Spanish firm ABENGOA Solar and the Algerian conglomerate Cevital along with several German banks and engineering companies.
The Sueddeutsche Zeitung newspaper said in June that electricity could begin flowing to Europe within 10 years.
West LB analyst Zank said some plants were already being developed in North Africa and "one can say that solar thermal energy will already be produced next year, but not with the intention of exporting this electricity to Europe."
Undersea networks could be built quickly, he added, but "at the moment the costs are so high it is not economically viable."
German Chancellor Angela Merkel and European Commission president Jose Manuel Barroso have hailed the initiative however, though others have voiced criticism.
German Social Democratic deputy Hermann Scheer told AFP it was not necessary to go to North Africa to collect the sun's rays, and added: "We could invest the 400 billion euros here" in the recession-hit eurozone.
He also preferred a network of decentralised operators that produced renewable energy from many sources rather than having one key project in the hands of major corporations.
Others doubt producer countries would fully benefit from a plan designed with Europe in mind, leading the business daily Handelsblatt to warn of potential "eco-colonialism."
