Technology
Solar Thermal Power Plants are large scale renewable energy infrastructures using heat produced by contracted solar beams (Concentrated Solar Power (CSP)). Mirrors concentrate solar beam on a receiver. The produced heat with temparatures of 400ºC to 1000ºC can be used directly, be transformed into electricity or stored.
Concentrating Solar Power (CSP) Technologies
CSP technology, being quite different from the more popular photovoltaic equpiment, concentrates sunlight to effectively create heat to raise steam. However, there are different types of technology working under title of CSP. In the following chapters, the idea of the “parabolic trough”, the “power tower”, the “Fresnel mirror system” (or simply “linear Fresnel”) and the “dish” will be presented.
Parabolic Trough
Power Tower
The power tower really lives up to its promise. Compared to other CSP technologies, it can create the highest degree of temperature. Surrounded by mirrors reflecting light onto an elevated and centered tower, the power tower generates heat of about 1,000 C°.[1] By transferring the reflected concentrated solar radiation to a fluid, steam is being produced that expands on a turbine in order generate the intended electricity.[2]

Cost Developments
Greenpeace, Solarpaces and ESTELA elaborated scenarios for the market potential and cost degression of the CSP technology with a timeline to 2050. According to the ambitious scenario costs per installed kW could come down from 3.060 € in 2015 to 2.160€ in 2050 (Greenpeace, Solarpaces, ESTELA, (2009)).
Markets
Europe
Spain
Africa
MENA region
The MENA region with its high level of solar radiation is the target of different initiatives to develop CSP on a large scale. This is a chance to improve the economic and social situation of the region itself. A recent study assesses the manufacturing capabilities and potentials for different CSP components in the MENA region. The study concentrates on the glass and mirror industry, electronic and electrical industry as well as steel industry and in terms of countries on Morocco, Algeria, Tunisia, Egypt and Jordan. (Worldbank, ESMAP (2011)). The study assumes that the major driving factor for the development of a local CSP industry in the MENA countries is the fast rise of installed CSP capacity in the region. The most optimistic scenario with 2 GW of installed CSP capacity in 2020 shows that local manufactured added value of CSP plants could reach almost 60 percent of the value chain by 2020. This equates to US$14.3 billion of additional industrial value added and a creation of permanent 64,000 to 79,000 local jobs ( at least 70% in construction and manufacturing sector) until 2025.
