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.

South Africa: Roadmap Sets 21 GWth target for 2030

Submitted by Baerbel Epp on September 17, 2015
Roadmap South AfricaAround 21 GWth (30 million m² of collector area) are to be installed in South Africa by 2030 – half a square metre per inhabitant. More than 200,000 additional jobs could be created by then. These are the ambitious targets of the South African Solar Thermal Technology Roadmap, SA-STTRM. It is a challenging target when compared with the only around 2.3 million m² which were installed in the country by 2014, but a realistic one when compared with the current deployment rates of countries such as Cyprus with 0.6 m²/head or Israel with 0.54 m²/head at the end of 2013. The chart shows the projected total solar thermal collector area between 2014 and 2030 based on the aim of reaching 0.5 m² of installed collector area per inhabitant by 2030.

Austria: Results of 40 Monitored, Non-Residential Projects

Submitted by Baerbel Epp on July 29, 2015

The sixth invitation to tender for large-scale solar thermal systems in Austria is still accepting applications until 24 September. The Austrian Climate and Energy Fund has again allocated a budget of EUR 5.9 million for installing collector fields of between 100 and 2,000 m2 for process heat, district heating, solar cooling, systems with high solar coverage above 20 % in trade and business and innovative technologies. The subsidy covers 40 % of the additional, environmentally relevant costs of the installation and grants a 5 % bonus for small and medium enterprises. As in the past, applicants must consult with experts from one of the three selected Austrian research institutes before submitting their proposal. Over the first five years, the Austrian Climate and Energy Fund spent EUR 17,258,324 on 163 projects. The pie chart shows the distribution of the 163 approved projects broken down by application.

Worldwide: Rough Estimates Say between 0.5 and 2.2 Million Solar Heating and Cooling Jobs

Submitted by Baerbel Epp on June 23, 2015
IRENA job pie chartData on the number of solar water heating and cooling jobs differs greatly from publication to publication. According to the annual study Renewable Energy and Jobs – Annual Review 2015 by the International Renewable Energy Agency (IRENA), there were approximately 764,000 people employed in solar heating and cooling globally in 2014, 16 % lower than in 2013 because of the market decline in China. The pie chart shows the distribution among the main markets. The Solar Heat Worldwide 2013 report, published in June 2015 by Austrian research institute AEE INTEC, assumes worldwide employment figures in solar thermal to add up to no more than 460,000 full-time jobs in 2014 (find both studies attached).

IEA SHC: Market Report Aggregates 56 Country Statistics

Submitted by Baerbel Epp on June 16, 2015
Solar Heat WorldwideIt is the most comprehensive publication on the global solar water heating market: the annual study Solar Heat Worldwide. On behalf of the IEA Solar Heating and Cooling Programme (SHC), Austrian research institute AEE INTEC has gathered data on 2013 market development from 56 countries worldwide – covering 95 % of the world market. The institute has asked national stakeholders for newly installed capacity, type of technology and application. Accumulating such detailed information at global level gives a comprehensive overview of the world market for solar heating and cooling. According to an extrapolation of the missing 5 %, installers set up a total capacity of 55 GWth – or 78.6 million m2 of glazed and unglazed solar collectors – in these 56 countries. The pie charts show the growing importance of large domestic hot water applications in multi-family buildings as well as the tourism and public sector (see page 36/37 of the attached study). In 2013, 17 % of the newly installed collector capacity was installed in this segment (right), whereas it only accounts for 9 % of the total installed collector capacity in operation (left). The number of unglazed solar collectors for private swimming pools has diminished worldwide. Although they still make up 6 % of the total capacity, they only contributed 3 % to the new collector capacity in 2013. With 577 MWth (0.8 million m2) of newly installed capacity in 2013, non-residential applications, such as district heating, process heat and cooling, are still a real niche market.

IEA SHC Task 52: Seeking Cost-optimised Urban Energy Systems

Submitted by Baerbel Epp on May 30, 2015
How can solar energy be ideally integrated into an urban energy system? This has been the key question of IEA SHC Task 52: Solar Heat and Energy Economics in Urban Environments. One and a half years after the task´s start in January 2014, scientists from Germany, Denmark, Austria and Switzerland met in Freiburg for the third task meeting in mid-April to discuss cost assessments of existing plants and models for analysing complex urban energy systems. One of the first published outcomes is a study carried out by Austrian research institute AEE INTEC. It lists the costs of existing solar district heating plants in Denmark, Germany and Austria. The chart shows the preliminary results from levelised heat costs calculated for 29 collector fields of sizes between 500 and 55,000 m² integrated into district or micro grids.

France: New ESCO Focuses on Process Heat

Submitted by Baerbel Epp on May 2, 2015
Logos SHIPA start-up company will host the next Task 49 meeting in Montpellier, France. This is unusual for the IEA Solar Heating and Cooling Programme, but the business target of French company Sunti is a perfect fit for Task 49, which aims at increasing solar heat integration into industrial processes. Sunti was founded in November 2014 by Jean-Michel Germa, a pioneer of the renewable industry who owns a 40 % stake in French La Compagnie du Vent. The new business wants to sell process heat to firms in France and the Mediterranean region as an Energy Service Company (ESCO).

Austria: Business as Usual Results in Market Decline

Submitted by Baerbel Epp on April 20, 2015
AEE Intec Chart 1If the Austrian solar thermal sector keeps doing business as usual, newly installed collector area will continue to decrease and end up at 122,000 m² in 2025 (152,000 m² in 2014), while collector area in operation will stagnate at around 5 million m² (4.18 million m² at the end of 2013). This is the key message of the Austrian roadmap Solarwärme 2025 (Solar Heat 2015). In their study, Christian Fink and Dieter Preiß, both from Austrian research institute AEE Intec, conclude that the downward trend is a result of shrinking demand from owners of single- and two-family buildings, especially regarding existing building stock. It seems as if the demand from the ecologically aware clientele has already been met, and it needs new marketing strategies to target other homeowners.
