Italy: New Solar Cooling Systems and Opportunities

Submitted by Baerbel Epp on June 7, 2017
MayaGovernment incentives have been pushing solar cooling forwards in Italy. The large budget available for national incentive scheme Conto Termico 2.0 has made several service providers optimistic about the future of the Italian market. For example, Mario Colaiemma from Maya, the European distributor of Japanese Yazaki chillers, said that “Italy was the key market for our solar thermal-driven chillers in 2016.” The photo shows a typical solar cooling system based on slightly below 50 m² of vacuum tube collectors connected to a 17.6 kW chiller. It was installed in Sicily, also home to two solar cooling plants by German chiller manufacturer Fahrenheit (formerly Sortech). Gregor Feig, Head of Sales at Fahrenheit, said in March 2017 that “two sorption cooling systems were put into operation in data centres in Enna and Caltanissetta, in the very sunny region of Sicily. Two more systems have been delivered, but haven’t gone online yet.”

Big Ups and Downs on Global Market

Submitted by Baerbel Epp on April 26, 2016
The global solar thermal market went into another year of notable decline in 2015. With 37.2 GWth, the newly installed glazed and unglazed collector capacity in the 18 largest countries was 14 % lower than in 2014 (43.4 GWth). Between 2013 and 2014, the decrease in these 18 major countries – which represent 95-97 % of the world market – had been 15 %. The further slowdown last year was the result of diminishing collector area figures in China (-17 %), and in Europe (nine biggest nations down by -5 %). The countries with the highest growth rates last year were Denmark (+55 %), Turkey (+10 %), Israel (+9 %) and Mexico (+8 %). The chart shows both 2015’s newly installed collector area, broken down by collector type – flat plate, vacuum tube and unglazed collector area, and the 2014-2015 growth rate (excluding China, whose 2015 market volume was 21-times larger than Turkey, which ranked second). China added 30.5 GWth in 2015 of which 12.6 % were flat plate collectors (5.5 million m2).

SHC 2015: 14 Expert Interviews on Research Highlights and Technology Trends on Tape

Submitted by Baerbel Epp on January 13, 2016
Videos SHC2015
From 2 to 4 December 2015, the SHC2015 conference in Istanbul brought together 233 researchers, industry specialists and other experts on solar heating and cooling. With 14 video interviews filmed at the conference, solarthermalworld.org highlighted the trends and pinpointed the crucial issues of today's global solar heating and cooling sector. The videos were jointly financed by the IEA Solar Heating and Cooling Programme and the European Copper Association. They are available for download on the solarthermalworld.org YouTube channel.
 

Taiwan and Japan: Commonalities and Differences

Submitted by Baerbel Epp on October 29, 2015

Taiwan and Japan have more in common as it seems at first glance: Both countries do not only belong to the same world region, but their 2014 market volume was of the same size too – around 100,000 m2 of newly installed collector area. And last but not least, vacuum tubes play only a minor role in both countries. Another factor which Taiwan and Japan have in common: they are hardly in the focus of the global solar thermal industry. One difference, however, is that Taiwan benefits from a support structure, whereas the Japanese industry is on its own – still, both markets are shrinking.

Solar Air-Conditioning System Using Single-Double Effect Combined Absorption Chiller (2014)

Submitted by Raquel Ponte Costa on February 19, 2015

This presentation on solar air-conditioning system was given by Kawasaki’s Hajime Yabase, together with Kiyohshi Saito of the Waseda University and Muhammad Idrus Alhamid of the University of Indonesia, at the ATMOsphere conference which took place in Tokyo from 3 to 5 February 2014.  The speakers outlined the numerous advantages of using double-effect absorption chillers in solar air-conditioning system.    Absorption chillers use water as refrigerant instead of Freon, they consume less energy than electric chiller and different energy sources can be used.  The presentation also compares a

Overview of Solar Thermal System in Japan (2012)

Submitted by Raquel Ponte Costa on December 3, 2014

This overview was presented by Takahiro Nagata of the Japanese Institute of Energy Economics during a seminar on “The Japanese Market for Heat Generation by Renewable Energies” organized in May 2012 under the German project “Exportinitiative Erneuerbare Energien” supported by the German Ministry for Economy and Energy.

Renewable Energies for Remote Areas and Islands (2012)

Submitted by Raquel Ponte Costa on September 11, 2014

The Renewable Energy Technology Deployment, a sub-group of the International Energy Agency with the mandate to accelerate the market introduction and deployment of renewable energy technologies, issued in 2012 a report on the possibility of deploying renewable energy technologies into remote islands and regions. The communities studied in the report live in different climate conditions and latitudes, from Alaska to Spain, from Japan to Ecuador, but face similar problems in terms of distance from more populated areas. The report shows technical, economic and energy issues facing remote areas; it provides examples, perspectives and inspiration on how to develop sustainable energy strategies, ultimately reducing long-term costs of energy.
