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.

European R&D Programme Horizon 2020: Good Opportunities for Solar Thermal?

Submitted by Baerbel Epp on October 3, 2015
Horizon 2020 budget sharesThe European Commission introduced its work programme 2016/2017 for the R&D funding programme Horizon 2020 during two info days in Brussels on 14 and 15 September. One of the first presentations was by Paul Verhoef, Head of the Renewable Energy Sources unit at the EU’s DG Research & Innovation, who showed that solar thermal has so far been gravely underfinanced during the 2014-2015 calls. The cumulated budget for solar heating and cooling was EUR 4.4 million out of a total of EUR 554 million, which means a share of less than 1 %. The pie chart, which depicts the allocation of the precisely EUR 553.8 million during 2014 and 2015, makes clear that energy sources such as ocean-based ones have received almost 10 times as much funding (EUR 41.4 million), and the Biofuels/Bioenergy sector has received an almost 20 times larger share of the total budget (EUR 83 million).

Solar Cooling 2.0: New Generation Growing Up

Submitted by Baerbel Epp on October 1, 2015
Task 53The workshop New Generation Solar Cooling & Heating Systems held in Rome, Italy, on 23 September 2015 was the opportunity to check the status of both research on and market developments in solar cooling technology. The half-day event, which had about 40 participants, was jointly organised by Task 53 of the IEA Solar Heating & Cooling Programme and the German Eastbavarian Institute for Technology Transfer, OTTI e.V., and took place a day before the start of OTTI’s 6th International Conference on Solar Air-Conditioning. Above all, the workshop provided a platform for presenting the first outcomes of the international research cooperation TASK 53 entitled New Generation Solar Cooling & Heating Systems, which was launched in March 2014, will end in 2017 and involves 10 countries, some from outside Europe (see the attached introductory presentation). 

Brazil Offers New Green Building Credit Terms

Submitted by Baerbel Epp on September 29, 2015
Minha Casa Minha VidaSince June 2015, the CAIXA bank owned by the Brazilian government has been offering improved financing conditions for energy-efficient housing projects built under the social housing programme Minha Casa Minha Vida (MCMV) to promote energy saving. As growing electricity demand is constantly driving up prices, the government wants to foster the use of any technology which could lower power consumption in newbuilds. Circular Caixa 681 now offers new financing conditions for projects which include energy efficiency measures – primarily, solar thermal.

IEA SHC Task 42: Latent Heat Storage Has Huge Potential in the Long Run

Submitted by Baerbel Epp on September 25, 2015
IEA SHC Task 42In their position paper published in August 2015, the scientists of IEA SHC Task 42 (Compact Thermal Energy Storage) summed up the key results of their work between 2009 and 2015. Operating agent Matthias Rommel sees huge potential for latent heat and sorption materials in the long run – in seasonal solar heat storage for small and medium applications, as well as in the building sector. So-called smart grids will also require more heat storage units when devices such as heat pumps and co-generation plants are based on electricity grid requirements. Rommel views the definition of measurement standards for PCM materials as one of the task’s big achievements, which will help in material development. Furthermore, a research group from German research institute ZAE Bayern has performed a first cost estimate of compact heat storage technologies.  

Bonilait Dairy: Largest Solar Process Heat Installation in France

Submitted by Baerbel Epp on September 24, 2015
Bonilait FranceThe solar heat supply system of dairy processor Bonilait Protéines, which has its factory near the French town of Poitiers, is a unique showcase in many ways. First of all, it is currently the largest solar process heat installation in France. Second, it is equipped with drainback technology delivered by Belgium company Sunoptimo. And third, it is the first solar process heat installation which is operated by EDF Optimal Solutions as an Energy Service Company. EDF Optimal Solutions is a provider of energy efficient solutions for all kinds of commercial users in a variety of sectors. The photo shows the around 1,500 m² collector field with flat plate collectors of type Vitosol 200 delivered by German heating boiler manufacturer Viessmann and installed on a support structure above the parking lot next to the factory.

Uruguay: The Battle for Market Growth Continues

Submitted by Baerbel Epp on September 23, 2015
Uruguay market developmentUruguay, whose population of 3.4 million makes it one of the smallest countries in Latin America, has shown positive market development since 2007. Cumulated installed solar thermal power saw a notable increase from 1 to 9.5 kWth per 1,000 inhabitants. According to numbers published by the National Energy Department and the annual national energy report, the country’s total collector area installed by the end of 2014 amounted to 46,241 m². Mesa Solar, the multi-sector network for the promotion of solar energy in Uruguay calls for accelerated growth to achieve 1 million m² in 2020. The official target of the government is 150,000 m² until 2024.

Egypt and India: UNIDO Supports Industrial Solar Heat

Submitted by Baerbel Epp on September 22, 2015
UNIDOThe United Nations Industrial Development Organization (UNIDO) started two projects in the first quarter of this year with the aim of increasing the deployment of solar process heat: January of 2015 marked the launch of a 5-year programme in cooperation with the Indian Ministry of New and Renewable Energy (MNRE) to promote business models for an increased market penetration and scale of concentrated solar thermal heating and cooling applications. Three months later, UNIDO launched the 5-year programme Utilizing Solar Energy for Industrial Process Heat in Egyptian Industry together with the Egyptian Ministry of Industry, Trade and Small and Medium Enterprises. Both projects are funded by the Global Environment Facility (GEF).
