Maximum latitude of implantation: around 40°, including the south of Europe if one accepts to lose during the winter months. This loss is less strong for power stations with towers and adjustable mirrors.
So basically not in Europe, except in the far south of Spain. The south of Italy is generally sunny, but due to the seas surrounding it does not benefit from a correct average DNI for CSP. As soon as there is a bit of mist or cloud, the performance drops.
Moreover, to my knowledge (I could be wrong, correct me with source) there is no significant CSP installation in Italy, which has nevertheless been quite generous in terms of solar subsidies.
Absolutely. Italy had a few years ago projects with cylindrical-parabolic mirrors, but does not seem to have followed up. There remains above all Spain, which recently decided on 3 MWe of projects by 000.
Each year, Eurobserver reports on developments for each type of electricity production since 2010. See the site of the same name.
Regarding solar thermodynamics in general, we could witness the great return of the solution of the 1970s: tower and adjustable mirrors, thanks to the possibility offered by day/night storage of 16 hours which, despite the production costs of electricity that will remain higher than photovoltaic, can produce at night. With molten salts or later silica or alumina particles (to reach temperatures above 700°C and therefore yields of 50%) as thermal storage materials.
Current typical example, completed in 2018, the integrated complex of Ouarzazate, with power plant n°3.

Morocco has 3 other similar projects, and the ambition to reach 52% of its renewable electricity production in 2030, many export projects of energy vectors from PV and wind to Europe...
This is not at all in line with the letter of Désertec, but it is in line with the spirit, with the dynamics that this kind of mega-projects may have generated.
