Desertec, Europe's Saharan power plan : Official hopeful Sahara could one day deliver 15 percent of Europe's electricity

A 400 billion euro ($774 billion) plan to power Europe with Sahara sunlight is gaining momentum, even as critics see high risks in a large corporate project using young technology in north African countries with weak rule of law.

Desertec, as the initiative is called, would be the world's most ambitious solar power project. Fields of mirrors in the desert would gather solar rays to boil water, turning turbines to electrify a new carbon-free network linking Europe, the Middle East and North Africa.

Its supporters, a dozen finance and industrial firms mostly from Germany, say it will keep Europe at the forefront of the fight against climate change and help North African and European economies to grow within greenhouse gas emission limits.

Others warn of numerous pitfalls, including Maghreb politics, Saharan sandstorms and the risk to desert populations if their water is diverted to clean dust off solar mirrors.

They say the concentrated solar power (CSP) technology behind Desertec involves greater costs and risks than the fast-growing patchwork of smaller-scale photovoltaic cell installations that generate most of Europe's solar energy today.

Desertec's founders are lured by the fact that more energy falls on the world's deserts in six hours than the world consumes in a year.

Proposed by the Club of Rome, an international group of experts that suggests solutions to global problems, Desertec became an industrial project last month when reinsurer Munich Re hosted its launch at its headquarters in the Bavarian capital.

Desertec officials say the Sahara could one day deliver 15 percent of Europe's electricity, but expect the plan to advance in small stages with completion not before 2050.

Desertec would need 20 or more efficient, direct-current cables each costing up to $1 billion to transmit electricity north beneath the Mediterranean.

CSP installations placed in the Sahara generate around 30 percent more power per area than in southern Spain, according to Morocco's renewable energy agency CDER.

"Desertec can help reduce emissions in Europe and foster economic and social development in northern Africa, so everyone loves this project," said Santiago Siage, head of Desertec consortium member Abengoa Solar.

Abengoa is developing installations combining CSP with combined-cycle gas power generation in Morocco and Algeria.

Southern countries that import most of their energy like Morocco, Tunisia and Jordan would also benefit from Desertec.

Morocco buys in 96 percent of its energy and subsidizes fuel to make it more affordable for the poor, a massive drain on state resources that could be used to fight poverty and bring services to isolated rural areas.

The Moroccan government says Desertec could solve Morocco's energy dependency and leave plenty of power for Europe.
