Das Projekt "IEA SHC Task 49/IV Solar Process Heat for Production and Advanced Applications" wird/wurde gefördert durch: Österreichische Forschungsförderungsgesellschaft mbH (FFG). Es wird/wurde ausgeführt durch: AEE, Institut für Nachhaltige Technologien.Solar Heat for Industrial Processes (SHIP) is currently at the early stages of development. Less than 100 operating solar thermal systems for process heat are reported worldwide (as of 2009), with a total capacity of about 24 MWth (34,000 m ). Most of these systems are of experimental nature, and are relatively small scale. However, there is great potential for market and technological developments, as 28Prozent of the overall energy demand in the EU27 countries originates in the industrial sector, majority of this is heat of below 250 Grad C. Following objectives had been defined for the work within the IEA SHC Task 49/IV: Process heat collectors: - Improving solar process heat collectors and collector loop components - Providing a basis for the comparison of collectors with respect to technical and economic conditions - Giving comprehensive recommendations for standardized testing procedures. Process integration and Process Intensification combined with solar process heat - Improved solar thermal system integration for production processes by advanced heat integration and storage management, advanced methodology for decision on integration place and integration types - Increase of the solar process heat potential by combining process intensification and solar thermal systems and fostering new applications for solar (thermal/UV) technologies. Design Guidelines, Case Studies and Dissemination - to provide a worldwide overview of results and experiences from solar heat for industrial process systems( including completed and ongoing demonstration system installations using monitoring data, as well as carrying out economic analyses) in order to lower the barriers for market deployment and to disseminate the knowledge to the main target groups involved - to develop a performance assessment methodology for a comparison and analysis of different applications, collector systems, regional and climatic conditions - to support future project stake holders by providing design guidelines, simplified fast and easy to handle calculation tools for solar yields and performance assessment - to investigate system solutions for stagnations behavior, control and hydraulics of large field installations.
Das Projekt "Solar hydrogen via steam-gasification of carbonaceous materials under direct high-flux irradiation - Heat & mass transfer phenomena" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich, Institut für Energietechnik.The project aims at investigating the fundamentals of heat and mass transfer phenomena in high-temperature multiphase reactive flows exposed to high-flux irradiation. The application is focused on the development of solar reactor technology for the production of hydrogen via steam-gasification of carbonaceous materials using concentrated solar radiation. Solar hybrid thermochemical processes, as the one targeted in this project, make use of fossil fuels as the chemical source of hydrogen production and concentrated solar energy as the energy source of high-temperature process heat. Industrially relevant examples include the thermal gasification of coal, the thermal cracking of natural gas, the thermal reforming of natural gas, and the carbothermic reduction of metal oxides, for producing synthetic fluid fuels with upgraded calorific value. These hybrid solar processes offer viable and efficient routes for fossil fuel decarbonization and CO2 avoidance, and further create a transition path towards solar hydrogen. This project contributes to the advancement of the thermo-sciences aimed at the development of solar chemical technologies that will lead to cleaner, more efficient, and sustainable energy utilization.
