Concentrating Solar Thermal for High-Temperature Solar Process Heat

Submitted by Baerbel Epp on September 23, 2017
CNRSEven energy-intensive, high-temperature industrial processes can be supplied by solar thermal systems if concentrating solar technologies are used. The EU-supported Solpart project, coordinated by the French-based CNRS public research organisation, is investigating the deployment of high-temperature solar-heated reactors for the industrial production of calcium oxide or quicklime, a major cement ingredient. A 30 kWth pilot reactor, including storage, is planned to be constructed and analysed in CRNS’s solar furnace (see the photo above). A mirror field will heat up the reactor particles placed in the receiver tower to between 900 and 950 °C for calcination. Solpart was launched in early 2016 and will end in December 2019.

IEA SHC Task 49: Solar Process Heat Showcase in Montpellier

Submitted by Baerbel Epp on October 5, 2015
Arcon-Sunmark ChileIndustry participation is key for the research work of IEA’s Solar Heating and Cooling Programme. Hence, the researchers of Task 49, Solar Heat Integration in Industrial Processes, used the last meeting in France in mid-September to hold a one-day workshop dedicated to Solar Heat Integration in Industrial Processes (SHIP) in cooperation with French start-up Energy Service Company Sunti. In Montpellier, SHIP 2015 gathered experts from the solar process heat collector industry, researchers, government and non-government organisations, as well as representatives for potential customers. Customers were particularly interested in the economic feasibility of systems. A wide variety of plants and operation data was presented. The photo shows the installation of the world’s largest solar process heat plant at the Gaby copper mine in Chile. Each year, the plant saves 6,500 tonnes of diesel, which would have had to be transported by 250 trucks through the desert.

Germany: Feed-in Tariff Changes May Benefit Solar Heat

Submitted by Baerbel Epp on September 22, 2014
Whereas Germany’s total collector sales are dropping, solar thermal companies see a glimmer of hope for big projects because of changed feed-in tariffs in the renewable electricity sector. So far, the cogeneration of heat and power has been the strongest competitor of large-scale solar heat for district heating and industrial projects. Because cogeneration had been a very attractive solution in terms of electricity prices, even a subsidy recovering all costs of a solar thermal investment wouldn’t have tipped the scales in favour of solar heat, a study by Fichtner stated in autumn of 2013. Now, however, cogeneration is starting to lose ground. 
 

Germany: New Industry Association Includes Concentrating Solar Process Heat

Submitted by Baerbel Epp on December 23, 2013
In September 2013, a group of German companies specialised in concentrating solar power (CSP) formally established the industry association Deutsche CSP. The group has had 38 members, 31 of which joined the association as well. In early summer 2013 already, the group had welcomed new member companies from the field of concentrating solar process heat, which also joined the association later - among them, Protarget from Cologne. Therefore, Deutsche CSP, the German Industry Association for Concentrated Solar Power, is now establishing a work group for solar process heat. 

Germany: Industrial Solar and Viessmann Work on Standardised Process Steam System

Submitted by Baerbel Epp on October 4, 2013

Together with the German Aerospace Centre's Institute of Solar Research, DLR, German companies Industrial Solar and Viessmann are working on a standardised hybrid system based on solar energy and fossil fuel to generate steam for industrial applications. The so-called SolSteam project is being funded by the German Federal Environment Ministry, BMU, and its first milestone is to find a customer for the pilot plant.

Solar Process Heat: European Commission Advocates More Research

Submitted by Baerbel Epp on June 2, 2013

In March, almost 40 scientists, engineers and solar process heat specialists met for the 1st workshop of the European InSun project, called "Exchange of experience made with the design and installation of solar process heat systems", which was hosted at the Institute for Solar Technology SPF in Rapperswil, Switzerland. The workshop focused on the experiences with the planning and installation of roof- or ground-mounted solar process heat systems - lead times, project schedule, as well as standards, guidelines and regulations in the different European countries. The photo shows a process heat project in Italy with 1.3 MW Fresnel collectors for the brick industry.

Renewable Energies in the MENA Region: Potential for Sustainable Energy Provision and Export to Europe (2008)

Submitted by Raquel Ponte Costa on October 24, 2011

This is a presentation delivered by Dr. Hans Müller-Steinhagen from the Institute of Technical Thermodynamics, German Aerospace Centre (DLR) during the Euromed Solar Workshop on EU-MENA (Middle East and North Africa region) Cooperation on Solar Power, held in Jordan.

Solar Thermal Power Plants: On the Way to Commercial Market Introduction (2008)

Submitted by Raquel Ponte Costa on November 9, 2009

This presentation made by Prof. Hans Müller-Steinhagen from the Institute for Thermodynamics of the German Aerospace Centre provides an overview of solar power plants, their current use, benefits and potential.

The presentation goes through examples of solar power plants, outlining the different systems and technologies available. An estimation of the costs and the profits of using such technologies is also provided, allowing, thus, to conclude on its paramount potential on electricity cost reduction.
