Solar electricity imports from the Middle East and North Africa to Europe

The huge solar resources in the MENA countries (Middle East and North Africa), significant improvements in concentrating solar power (CSP) technology and in power transmission technologies, and the urgent need to remove carbon emissions from the European (EU) energy system lead to an increased interest in an EU-MENA electricity grid interconnection. As contribution to the current discussions about DESERTEC, MedGrid and other initiatives this article describes the approach and results of an analysis of possible solar electricity import corridors from MENA to Europe including Turkey. The study is based on solar energy potentials of the MENA countries identified by remote sensing, reviewed performance and cost data of generation and transmission technologies, and geographic data and information systems (GIS) for the spatial analysis. CSP plants combined with high temperature heat storage and high voltage direct current (HVDC) overhead lines and sea cables represent the key technologies for implementing this promising option for renewable energy import/export. The total technical solar power generation potential from remote sensing analysis in the seven MENA countries considered was calculated to about 538,000 TWh/yr. This huge potential implies that less than 0.2% of the land suitable for CSP plants would be enough to supply 15% of the electricity demand expected in Europe in the year 2050. A GIS analysis of potential future HVDC corridors led to the description and characterization of 33 possible import routes to main European centers of demand. - Highlights: ► Concentrating Solar Power in the Mediterranean Region (MED-CSP 2005) (www.dlr.de/tt/med-csp). ► Trans-Mediterranean Interconnection for Concentrating Solar Power (TRANS-CSP 2006) (www.dlr.de/tt/trans-csp). ► Concentrating Solar Power for Seawater Desalination (AQUA-CSP 2007) (www.dlr.de/tt/aqua-csp). ► Risk of Energy Availability: Common Corridors for Europe Supply Security (REACCESS 2009) (http://reaccess.epu.ntua.gr/). ► Combined Solar Power and Desalination in the Mediterranean (MED-CSD 2010) (www.med-csd-ec.eu).
