Germany: Fraunhofer ISE’s New Climate Test Stand

Submitted by Baerbel Epp on January 16, 2013

At the end of November, the Fraunhofer Institute for Solar Energy Systems ISE started its new test stand for solar thermal collectors. Using this test stand, the scientists aim to simulate mechanical loads under extreme climatic conditions, e.g., wind or snow, and analyse their effects on the solar collectors. The test stand is part of the MechTest project, which has been running at the Fraunhofer ISE with support from the German Federal Environment Ministry (BMU) since 2010. The scientists hope that the project will be able to determine the mechanical stresses put on solar collectors and their mounting systems by wind and snow in order to develop quality assurance systems based on these results.

Designing Solar Thermal System for Selected Industrial Processes (2011)

Submitted by Raquel Ponte Costa on March 15, 2012

This is a presentation by Stefan Heß of the Fraunhofer ISE, given during the International Conference Solar Process Heat that took place in March 2011 in Austria.

Industrial process heat accounts for more than 20% of the final energy demand in Germany. 33% is needed at temperatures below 150°C, which can be easily achieved with solar thermal collector. The presentation explains why solar thermal is not used for industrial process heat in Europe. Financial restrictions and complex system integration are considered to be the main barriers to the development of this technology.

India: Innovative Solar Cooling System at Solar Energy Centre

Submitted by Baerbel Epp on August 10, 2011

 Solar air conditioning demonstration system” The Solar Energy Centre in Haryana State can now score with a new and innovative solar air conditioning demonstration system: Developed by Thermax, one of India’s leading waste heat recovery and cooling manufacturers, the system with a 100 kW cooling capacity has an integrated triple-effect Vapour Absorption Chiller (VAC) and solar parabolic concentrators. Both components were developed locally through a 15-month cooperative application research by the Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), the Indian Institute of Technology Kanpur (IITK) - both from India -, and the German ISE Fraunhofer Institute.

New IEA Task for Solar Process Heat

Submitted by Baerbel Epp on August 8, 2011

At their meeting in June, the Executive Committee (ExCo) of the International Energy Agency (IEA) gave green light to a new task for solar process heat. The IEA-SHC (Solar Heating and Cooling) Task 49 – “Solar Process Heat for Production and Advanced Applications“ - will start in January 2012 and run for four years. The now rough outline of the task will be further specified in a second “Task Definition Meeting“ at the Solar World Congress in Kassel, Germany, on 2 September 2011. Task participants will then take the suggestions made by the ExCo to spell out the activities for solar process heat in more detail.

Argentina: Market Situation and Barrier Analysis

Submitted by Baerbel Epp on July 16, 2011

 Thermosiphon installations on the roof of a seminary in San Salvador de Jujuy, Argentina” Björn Nienborg, researcher at the German institute Fraunhofer ISE, has carried out a survey among solar collector manufacturers and importers in Argentina as part of his Master's study “Renewable Energy Management” at the University of Freiburg. His recently published “Solar Thermal Water Heaters in Argentina” gives a status report on the Argentine solar thermal market, as well as its manufacturers and suppliers. It is available as a detailed version in Spanish and a shorter one in English. The photo shows a 20 m2 thermosiphon installations on the roof of a seminary in San Salvador de Jujuy, Argentina.

Germany: International Training Seminar Solar Process Heat in Munich

Submitted by Baerbel Epp on April 6, 2011

 Solar Process Heat” While solar heat for domestic and service applications shows increasing market shares across Europe, solar process heat seems still very much in its infancy. In principle, the potential is enormous: About 30% of the total industrial heat demand requires temperature levels below 100°C, which can be met by commercially available solar thermal collectors. The international training seminar Solar Process Heat, which takes place as an official side event of the Intersolar Europe in Munich on 9 June 2011, will offer information and know-how on solar thermal system design for solar process heat installations.

Solar Cooling: German Fraunhofer ISE compares PV and Solar Thermal

Submitted by Baerbel Epp on February 14, 2011

 Saved primary energy and difference in total annual cost ” Over the last 5 years, the number of installed solar cooling systems worldwide increased tenfold. The main obstacles for a more pervasive and faster market development are high upfront costs and lack of experience among main stakeholders, such as planners and architects. Based on various simulations, German institute Fraunhofer ISE analysed the saved primary energy and total annual costs of solar thermal, photovoltaic and conventional solutions for heating and cooling by using the example of a hotel in Madrid (see attached presentation).

The Thai Solar Thermal Industry Outlook (2007)

Submitted by Raquel Ponte Costa on June 26, 2010

This document was produced by the Solar Thermal Association in Thailand. It provides a thorough overview of the Soltherm project. The Market Development Solar Thermal Applications in Thailand project (Soltherm Thailand) is funded by the EU-Thailand Economic Cooperation Small Project Facility (EU-SPF) and jointly implemented by the Joint Graduate School of Energy and Environment (JGSEE), the International Institute for Energy Conservation (IIEC) and the Fraunhofer Institute for Solar Energy Systems (ISE).

Renewable Energy Policy Country Profiles (2009)

Submitted by Raquel Ponte Costa on March 30, 2010

This report, published in the framework of the Re-Shaping project, provides an overview of the existing RES support schemes in the 27 EU Member States.

The project RE-Shaping aims to assist Member States in preparing for the implementation of the RES Directive (2009/28/EC) and to guide a European policy for RES in the mid to long term.

In this report, the past and present success of policies for renewable energies are evaluated and recommendations derived to improve future RES support schemes are provided.

Solar Cooling and Air-Conditioning (2007)

Submitted by Raquel Ponte Costa on February 16, 2010

This presentation was given by Hans-Martin Henning from the Fraunhofer-Institut for Solar Energy Systems ISE in Freiburg, Germany, during the Renewable Energy Week in Brussels in 2007.

Mr Hans-Martin Henning explains with these slides solar cooling and air conditioning processes and technologies, examples of solar cooling usage (factories, conferece centers, hotels and wine stores), current status and outlook as well.
