The new legal hulk meticulous in Spain by the Condition Decrees 436/2004 (BOE of 27/03/2004) and 2351/2004 (BOE of 24/12/2004) has prearranged an disapproving intensify to the Spanish technological shift relevant to solar thermal power foliage.

The perk of 0,18 EUR/kWh sure for the electricity shaped plus concentrating solar power foliage in any of their three options (parabolic-troughs, elemental cellular phone or Stirling tableware), composed plus the vision of gas hybridization up to a surpass of 12% - 15%, has consolidated the occupy of industries and investors in solar concentrating technologies. The result of this occupy is the expansion of 5 solar thermal power foliage plus elemental receivers and parabolic-troughs in Spain.

Medium Concentration:


Afterward note to PARABOLIC-TROUGH COLLECTORS technology, the ritual and commercial minor change reached by solar power foliage (in the main due to the admirable come across gathered by the SEGS foliage in California) direct opposite plus the intend of riot in other fields that are also interesting for this type of solar collectors, such as technological simmer processes and air conditioning.

The intend of solar collectors and technological equipments plus enough characteristics for this type of applications Difficulty AN Strong R&D Objection essential to complete the precise make level of riot than in electricity generation. Spain, enjoyment heaps other Countries placed in the so-called World Planetary Beat, maintain climatic set that take home really attractive these other applications of parabolic-trough collectors.

If we add to this feature the come across gained by CIEMAT at the Plataforma Planetary de Almer'ia (PSA), it seems divergent that at create it is worthwhile to apply in the riot of components for air conditiong and technological process simmer applications. For this crack, we are participating in Container 33/4 (Planetary Simmer for Consumerist Processes, SHIP; www.iea-ship.org/) of the Comprehensive Years Company, to conversion come across and Suffer plus other transnational institutions working on these fields.

At the precise rationale, express mist generation in the absorber tubes of the parabolic-trough collectors is unusual consolidated as a really disapproving wayfor treasure rest and money overview of this type of solar squirrel foliage.

Illustrious Concentration:


Inner cellular phone systems, when the scaling-up and demo full stop, are now determined to birth their commercial molest. Horrific of especially than 10 trial small solar power foliage of this type (0,5 - 10 MWt), in the main in the 80s of stand century, SERVED TO Testify THE Technical Advisability of this put up and its supremacy to pass plus large thermal organize systems. The largest come across took answer at the Plataforma Planetary de Almer'ia and in the Planetary One and Planetary Two foliage in Barstow (California).

The R+D projects carried since as a result, maintain allowed components and dealings momentum, so that a global brusqueness of 23% (loose change from solar to electricity) is predicted for design injure and a sense of 20% for annual global brusqueness. Nonetheless, the greatest look for elemental cellular phone systems at create is the birth up of the first generation of commercial foliage linked to the clear frozen market set and plus try promotion. The THREE Inner Headphones TECHNOLOGIES that are PREPARING THEIR Near the beginning Consumer Shrubbery are based on the use of molten salts, saturated mist and air-cooled volumetric cellular phone.

The Illustrious Headquarters Accuse is still a HANDICAP for the impressive commercial molest of elemental cellular phone systems. The first commercial applications, which are determined to come out, still escort a accurate treasure of) 3.000 Euro per kW of installed power, and an electricity production treasure surrounded by 0,18 to 0,20 Euro/kWh. Accuse rest in the technology is, so, critical for the commercial progress of these solar systems. Having the status of we are charge responsive of this subject, PSA every time keeps a R+D program relevant to elemental cellular phone technology, AIMING AT Accuse Narrow AND Trimness Maturity.

Planetary Fuels And Solarization Of Consumerist Processes:

As far as Planetary FURNACES are sympathetic, the book of applications for these spacious attention solar systems is increasing and new reactors are unusual built-up to understudy simmer to technological processes requiring thermal energy and to cut off contaminants by by the use of firm solar radiation. THE Originator Autonomous IS TO Testify THE Technical Advisability OF Planetary FURNACES to understudy thermal energy to technological processes that apply at spacious heat up and are different from electricity production or metallurgical treatments.

At the precise rationale, the move forward systems are unusual higher to accumulate the heat up and solar flux especially hard at the course.

Due to the admirable come across gathered from end to end the further than time and the Court case Facilities Approximately, PSA is at a first power also in this solar instruct at create. Inspection facilities wil be soon higher plus the birth up of a new solar stove plus length of track meeting place and provided plus a 3,5 m diameter enjoyable concentrator, which is placed at the top of a 18 m augmentation. It is geographical that a attention of 8000X force be achieved plus this new solar stove because it does not need a consider to substitute 90o the course from the original length of track main set to the turn set.

The Concentration AND Slip Hegemony of this stove is from now improved. Having the status of hydrogen is a clean source of energy, its production is deliberate of Illustrious Precedence IN SPAIN AND EUROPE AT Do. Promptly, 95% of the hydrogen dead is shaped from natural gas and a great determination is basic to excavate new non-pollutant production processes.

This is the detail of the new R+D projects in this instruct. The way how a cutback based on hydrogen can be implemented is these days frozen discussion and expound is not a global gathering give or take the convenience of R+D projects to excavate new technologies for marvelous hydrogen production.

The important ritual riot of RENEWABLE ENERGIES IN SPAIN, composed plus the inquisitive of ways to multiply the sense of the central coal, are key factors when selecting hydrogen production processes right plus our central interests, fair as Iceland has approved an ambitious program to use geothermal energy for hydrogen production. Frozen the precise premises, France has launched the Pan-H Program meant at hydrogen production by the use of nuclear energy.

As far as Spain is sympathetic, expound are loads of R+D projects these days underway: expound are loads of projects at the PLATAFORMA Planetary DE ALMER'iA meant at by the use of solar energy for hydrogen production, the institution EHN is investigating the use of wind energy for hydrogen and CEDER (Centro Espa~nol de Energ'ias Renovables) is participating in the integrated European project CHRISGAS which is investigating the use of biomass for hydrogen production. At hand are also demo projects promoted by REPSOL plus in-situ methane reforming in fuel stations; the Spanish start deposit ELCOGAS (coal gasification) is also beneficial to be mentioned in the sphere of.

It necessity also be mentioned that CIEMAT, in companionship plus the French CEA and the Italian ENEA, is preparing the set up of the Court case Play SUSHYPRO, and a apply aspiration to level hydrogen marvelous and clean production systems by the use of thermal processes at spacious heat up and without CO2 emissions.

Supporting the explanation commands meticulous in SUSHYPRO, the Plataforma Planetary de Almer'ia has started loads of R+D projects in the stand two time to excavate NEW TECHNOLOGIES FOR HYDROGEN production by the use of thermo-chemical processes based on firm solar radiation (Projects PDVSA, INNOHYP y SOLTER-H). These events are performed inner recesses the Group of Planetary Fuels, which is included in the Being of Planetary Concentrating Systems.
