NREA Study Project TRANS-CSP Trans-Mediterranean Interconnection for Concentrating Solar Power (WP 01 Transmission Technologies)

NREA Study Project TRANS-CSP Trans-Mediterranean Interconnection for Concentrating Solar Power (WP 01 Transmission Technologies) Project for the Research & Development Programme of the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU)

WP 01 Transmission Technologies Scope: Assessment, characterisation and comparison of technology options for the transmission of solar electricity produced by Concentrating Solar Power Plants or by other renewables from MENA to Europe Result: High Voltage Direct Current transmission (HVDC) is the least cost and most efficient solution

Power transmission via Hydrogen is possible, but 75 % of the solar electricity would be lost.

After closing the Mediterranean Ring in 2010, about 0. 5 % of European electricity

After closing the Mediterranean Ring in 2010, about 0. 5 % of European electricity demand could be imported through the conventional AC grid. If upgraded to European standards, 3 %. However, 45 % of the solar electricity would be lost over 3000 km. Source: OME

Security and Redundancy of Power Supply by a Future TRANS-Mediterranean HVDC Grid High Voltage

Security and Redundancy of Power Supply by a Future TRANS-Mediterranean HVDC Grid High Voltage Direct Current (HVDC) power transmission looses only 10 % over 3000 km distance. Like interstate highways, HVDC lines will serve long distance transfer, with only few outlets to the conventional Alternating Current (AC) grid which will be used analogue to country roads and city streets. By 2050, 700 TWh/y solar electricity could be imported from 20 locations in MENA at a cost of 5 c/k. Wh providing about 15 % of European electricity demand.
