The Desertec initiative hoped to deliver electricity from a network of renewable energy sources to Europe via cables under the sea.

Solar thermal power plants --which produce power from the heat of the sun--remain one of our favorite renewable energy technologies, but it might be in serious trouble. And this time the culprit is not cheap natural gas, the Koch Brothers, or the desert tortoise advocates. This time, the adversary is the other half of the solar family.
BOSTON--( BUSINESS WIRE )--Despite competitive photovoltaic prices and lingering environmental and financing concerns, concentrating solar power (CSP) technologies are poised for gigawatt-scale adoption in 2011; and future growth will remain healthy as the generation stack increasingly incorporates CSP plants in excess of 100 MW.
February 2, 2011 - BUSINESS WIRE -- Despite competitive photovoltaic (PV) prices and lingering environmental and financing concerns, concentrating solar power (CSP) technologies are poised for gigawatt-scale adoption in 2011. Future growth will remain healthy as the generation stack increasingly incorporates CSP plants in excess of 100MW. To land their share of this emerging market, utilities and developers will need a clear grasp of the economic and performance factors driving adoption of CSP's four main technologies, according to a new report from Lux Research.
You can say those three hurdles will always remain and not just for CSP, which uses reflectors to concentrate and beam sunlight toward a receiver for producing steam, which then goes to powering turbine-generators for producing electricity.
Concentrated solar power (also called concentrating solar power , concentrated solar thermal , and CSP ) systems use mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy , onto a small area. Electrical power is produced when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine ) connected to an electrical power generator. CSP is being widely commercialized and the CSP market has seen about 740 MW of generating capacity added between 2007 and the end of 2010. More than half of this (about 478 MW) was installed during 2010, bringing the global total to 1095 MW.

Après une polémique qui a duré plusieurs mois sur l’adhésion ou non de l’Algérie au projet Desertec, une visite du président de la République,Abdelaziz Bouteflika, en Allemagne a donné lieu à des contacts entre les promoteurs de Desertec et des responsables algériens qui faisaient partie de la délégation officielle, notamment le ministre de l’Energie et des Mines, Youcef Yousfi.
