Jordan is showing rapidly increasing demand for air-conditioning. Total annual emissions from cooling commercial buildings add up to 600,000 tonnes of CO2, an amount equal to emissions from about 120,000 passenger vehicles per year. This has prompted the German Agency for International Cooperation to initiate the project Solar Cooling in Industry and Commerce in Jordan. The German Technische Universität Berlin (TUB) played a key role in this transfer of technology and know-how for the planning and installation as well as monitoring of four solar-driven air-conditioning systems in public and private buildings. The photo shows the 388 m² collector field which was commissioned at Petra Guest House in February 2015, around the same time as the one at German Jordanian University.
With more than 200,000 visitors from 61 countries and 2,482 exhibitors, this year´s ISH trade fair in Frankfurt, Germany, set a new record. The biannual exhibition showed the latest trends in building and heating technologies, including renewable energy applications. During the one-hour press conference of the German heating industry association BDH, the world “solar” was not even mentioned once. Faced with decreasing interest in solar thermal across central Europe, the portfolio of the few exhibitors specialising in the technology included electric heating in one way or another. The photo shows a collector to regenerate boreholes which are connected to heat pump.
The 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.
During the last seven years, a group of scientists has monitored selected large solar thermal installations in Austria on behalf of the Austrian Climate and Energy Fund. The gathered data confirms that these plants have been reliable and produce satisfactory yields. Particularly the new generation of large-scale medium-temperature collectors either with a foil or with a second glass cover shows remarkable results in district heating use. The 2,490 m² solar field (see photo) which has fed heat into the district heating network of Graz, Austria, reached a yield of 489 kWh/m².
Three weeks before the ISH 2017 opens its doors again between 14 and 18 March 2017, the German renewable heating associations published their annual market statistics for 2016. The trend is clear: Low oil and gas prices have reduced demand for solar water heating systems (-8 %) and biomass boilers (-3 %), whereas the German heat pump industry can be more than satisfied with 17 % growth. The ISH is Europe’s largest trade fair for bathroom design, energy-efficient heating, air conditioning and renewable energies and takes place every two years in Frankfurt, Germany.
Industrial solar heat is far from being a standard yet, but it is more widespread than you might think. The first World Map of Solar Process Heat Specialists shows 71 companies in 22 countries which reported almost 400 reference systems. Together with additional plants included in the online portal ship-plants.info, the world market for industrial process heat comprises at a minimum 525 plants with an collector or mirror area of at least 416,414 m².
The Solar Thermal Federation of India (STFI) and the Indo-German Chamber of Commerce (IGCC) have teamed up for the international Solar Payback project, which aims to increase the use of solar thermal energy in industrial processes. The photo shows the partners during the Kick-Off Meeting in Mumbai, India, on 16 December 2016. Supported by the German Federal Environment Ministry funded by the International Climate Initiative, the three-year project will be implemented in India, South Africa, Mexico and Brazil. It is coordinated by the German Solar Association BSW-Solar and eleven partner organisations: three German companies, plus each target country’s national solar industry association and German chamber of commerce.
The ranking of the largest flat plate collector manufacturers is headed by the same four companies as last year: Greenonetec from Austria, Fivestar from China, Soletrol from Brazil and Bosch Thermotechnik from Germany. But aside from the continuity at the top, last year shows what different paths some markets have taken. Whereas Australian-based Solahart, one of the pioneers of global solar collector trade, as well as Soletrol, the largest Brazilian manufacturer, have lost ground, several others – such as Sunrain from China, Hewalex from Poland and Eraslan from Turkey – were able to report above-average growth for 2015 and rise through the ranks. The produced collector area of the overall 21 companies added up to 4,212,462 m². The number was 21 and not 20 because the last and second-last spot were occupied by companies with equal production output.
The Solar Keymark Network (SKN) discussed and approved new complaint procedures during its most recent meeting on the Greek island of Crete in mid-October 2016. Action had to be taken, as the first series of complaints filed in late 2015 against Swedish test lab SP about the certificates of Danish collector manufacturer Arcon-Sunmark was not resolved to the satisfaction of all parties involved. The results of the October meeting are described in a publicly available draft of the minutes on the SKN webpage.
In September 2016, Roger Hackstock returned as Managing Director of Austria Solar after having already occupied this position between 2002 and 2013. In the three years that he was not at the helm of the Austrian industry association, Hackstock published a book on the “Energiewende” (energy transition), worked as programme manager for the country’s Climate and Energy Fund and coordinated the Storage initiative as an independent consultant. During our interview, he spoke about the challenges solar heat has had to face over the years, as market demand for system solutions is steadily on the rise, and noted that he was happy to support the industry in this new era.
