IEA SHC Solar Academy: Solar Heating for Industrial Processes

Submitted by Baerbel Epp on June 6, 2017
SHC Academy LogoResearchers have worked intensively across national borders to increase deployment of Solar Heat for Industrial Processes (SHIP), which is regarded as one of the most promising solar thermal applications. When IEA SHC Task 49, Solar Heat Integration in Industrial Processes, was launched in 2012, there were reportedly around 120 SHIP systems adding up to 88 MWth. Over the last years, total installation figures have tripled to more than 500 systems and a minimum of 291 MWth globally.
 

IEA SHC: Solar Heat Worldwide Highlights Remarkable Achievements and Addresses Challenges

Submitted by Baerbel Epp on June 2, 2017
Solar Heat Worldwide TitleIn late May, the IEA Solar Heating and Cooling Programme (IEA SHC) published its annual report titled Solar Heat Worldwide (see the attached document). It is the most comprehensive study of solar heating and cooling markets around the globe and has been referenced by international organisations such as REN21 and IRENA. Based on data from 66 countries, the most recent report has grown from 76 pages in 2016 to 86 in 2017. It includes a new section which highlights last years’ encouraging market development of megawatt systems for solar district heating and solar process heat and a second part providing in-depth figures about the national and global markets of 2015.
 

Europe: Collector Field Is Main Cost Driver of Industrial Solar Heat Plants

Submitted by Baerbel Epp on May 31, 2017
Otti SymposiumScientists from Germany and Switzerland have recently analysed the cost structures of systems producing solar process heat. They presented their findings in mid-May at the Solar Thermal Energy Symposium, where they said they had identified great potential for cost-cutting and discovered a large spread of installation prices. Planning SHIP systems involved more work than doing the same for domestic applications, but it was the collectors that made up the lion’s share of the investment. The three-day symposium attracted around 230 experts from research and industry. As Germany’s major annual conference on solar heating and cooling, it focused this year on turnkey heating solutions, including solar ones for the housing market and industrial processes. It was the 27th symposium and, at the same time, the last one organised by the East-Bavarian Institute for Technology Transfer, OTTI, which filed for bankruptcy in February 2017. The symposium’s board of advisers has taken over sponsorship until a new conference organiser is found for 2018 (see attached flyer in German).

Brazil: Promising SHIP Case Studies in Pernambuco State

Submitted by Baerbel Epp on May 30, 2017
PernambucoSolar Heat for Industrial Processes (SHIP) is taking its first steps on the Brazilian market. Considering the mere handful of SHIP plants in operation in a country as huge as this one, the German Agency for International Cooperation (GIZ) is contemplating SHIP support measures as part of its long-term project Concentrating Solar Power in Brazil (2013 – 2018). There have been feasibility studies on SHIP plants in the north-east state of Pernambuco and the first online training course on solar process heat in March 2017 attracted 80 participants from across the country. 
 

Brazil: 2016 Market Statistics by Newly Founded Industry Association ABRASOL

Submitted by Baerbel Epp on April 30, 2017
Brazil Market Development 2016A recently introduced annual statistic by Brazil’s newly established industry association ABRASOL based in São Paulo shows that in 2016, the country was again the one with the third-largest number of new installations and the largest solar thermal market in South America. The 1,304,922 m² of newly installed glazed and unglazed water collector area (0.91 GWth) added in 2016 have put it only slightly ahead of India and behind China and Turkey. Brazil’s glazed collector market experienced a comparatively small drop of 4 % considering the country’s ongoing economic and political crisis and the slowdown of Minha Casa Minha Vida (My house, My Life), the programme which had made solar water heaters a requirement for new social housing projects. Reduced purchasing power led to a 10 % decline in the sales of unglazed collectors for swimming pools and vacuum tube collectors played only a minor role last year, garnering 2 % of sales.

Germany: Process Heat Supply from Vacuum Tubes and Air Collectors on the Rise

Submitted by Baerbel Epp on April 21, 2017
Process Heat StatisticsThere is a distinct difference between the make-up of the German solar process heat segment and the country’s solar thermal market in general and it concerns the type of collectors used. One in four collectors used in solar process heat systems is an air collector, although the technology contributes only around 10 % to the total collector area newly installed each year. The same has been true for vacuum tube systems, which showed a 35 % share in solar process heat installations among approved projects in 2016 – despite an overall market share of only 9 % last year. All figures are based on statistics provided by the University of Kassel’s Institute of Thermal Engineering, which has been in charge of the research accompanying the subsidy scheme on solar process heat under the auspices of Germany’s Market Rebate Programme for Renewable Energies or MAP.

China: Solar Process Heat and Space Heating and Cooling Rack Up Market Shares

Submitted by Baerbel Epp on April 19, 2017
CSTIFChina’s shift away from residential towards commercial solar thermal applications continues: The collector area of newly installed solar water heaters in single-family buildings declined by 26 % in 2016, whereas the ‘engineering segment’ remained stable last year (see the table below). This segment is comprised of all non-domestic hot water applications, such as space heating and cooling as well as applications in industry and agriculture. Overall, its share in the newly installed collector area went from 61 to 68 %. All figures were taken from the Report on the State of China's Solar Thermal Industry (July to December 2016), a document drafted by Dezhou-based consultancy Sun’s Vision on behalf of CSTIF, the Chinese Solar Thermal Industry Federation. CSTIF has presented this report – which also includes several development strategies – to the National Energy Board. 
 

Miraah in Oman: “Ahead of Schedule and Under Budget”

Submitted by Baerbel Epp on March 25, 2017
GlasspointReplacing gas with sunshine for enhanced oil recovery (EOR) is a cost-effective solution. This is the key message of US-based company Glasspoint, which has mobilised the biggest investment ever in a solar steam-producing unit in Oman. State-owned Petroleum Development Oman is building a concentrating solar thermal collector field called Miraah next to the Amal West oilfield. Once complete, it will generate more than a gigawatt of solar thermal power to drive EOR operations – saving Oman about 5.6 trillion BTUs of natural gas each year.

USA: Commercial Systems Dominate Californian Solar Thermal Market

Submitted by Baerbel Epp on March 24, 2017
California Incentive ProgrammeThe California Solar Initiative (CSI) – Thermal Program seems to have stabilised at around 20,000 m² (or around 200,000 ft²) of subsidised collector area per year. Commercial applications dominate the statistics, although there was a spike in the share of residential systems in 2016. The peak in applications for commercial pool heating in 2014 was due to the late addition of this type of system to the state subsidy scheme. It took almost a year before the level of incentives and other requirements were set, so that all the applications piling up over that period had to be processed in 2014. The data in the chart was provided by the California Public Utilities Commission (CPUC) and shows the subsidised and installed collector area for each year.

India: Proven SHIP Business Model with Third-Party Financing and Maintenance Contract

Submitted by Baerbel Epp on March 22, 2017
Harita SeatingThere has been growing demand for Aspiration Energy’s (AE) business of delivering systems that provide solar heat for industrial processes (SHIP). In January 2017, the turnkey SHIP supplier based in India completed a second solar field with 600 m² (180 kWth) of vacuum tube collectors for Harita Seating, which is one of the country’s leading manufacturers of automotive seating systems and part of the USD 7 billion TVS group. The first 600 m² system was commissioned in January 2015. Both fields combined meet around 50 % of the heat demand for degreasing and phosphating processes in Harita’s factory. The photo shows the solar thermal control panel in the production facility; the 3,000-litre solar thermal storage tank can be found on the right.
