Solar Thermal

Renovation check for solar systems

Austria’s government is making a total of € 100 million available for this new support, € 70 million of which is reserved for private homes. A similar scheme was already run in 2009, but back then less money was planned in for private homeowners. Grant applications may be made via the headquarters of building societies from 1st March to 30th June 2011.

Sener secures contract for five solar fields

With the contracts for the plants Aste 1A, Aste 1B, Termosolar Soluz Guzmán, Consol-Orellana and La Africa, the company now has a portfolio of 19 CSP power plants, in which it has provided or will provide the solar technology.

Sener will install its Senertrough collector, which is already being used in several operating plants, like Extresol 1 & 2 and Valle 1 & 2.

Sener develops single tank thermal storage

The single-tank storage system will work with an insulation barrier that separates salt in both cold and hot states. Typically the hot and the cold salt are stored in two different tanks. The objective is to design, construct, and test a reduced-scale prototype in the Valle 2 commercial plant, which Sener is constructing for Torresol Energy in Cádiz, Spain.

CSP-electricity from Tunisia for Europe?

At the beginning of July, Abdelhamid Triki, Tunisia's Minister for Planning and International Cooperation, announced during a visit to Saudi Arabia that his country intends to invest up to US$2 billion in solar projects in order to generate electricity for Europe. For the transport, an undersea cable to Italy will be installed.

Palmdale hybrid approved

The main power of the plant will be generated by combustion of natural gas, during daylight hours when the parabolic solar thermal collectors are in use, the solar field will provide about 10 % of the peak power generated. The solar field will provide heat directly to the heat-recovery steam generators to produce steam.

Switzerland overcomes solar thermal market stagnation

The background to this is the results of a survey carried out by the market research institute BSRIA among the most important manufacturers and importers, according to which 160,000 m2 of collector area will have been installed by the end of the year. The total installed collector area in Switzerland would then be 950,000 m2.

Innovative absorber utilises air humidity

The heart of the system is a black plastic absorber, which is 2 metres high, with a volume of 1 m³ and an effective surface area of around 80 m². It is linked with a greenhouse in which Buchholz has cultivated reed. Lightly contaminated wastewater fed into the greenhouse already evaporates at low temperatures.
