Record participation at SDH 2018 in Graz

Dear Reader, 


The SDH sector offers excellent opportunities for business. It was no surprise, then, that the 5th International Solar District Heating Conference attracted twice as many attendees as the previous event, which took place in the Danish town of Billund in 2016. In all, 350 experts from 33 countries flocked to the conference in Graz, Austria, in mid-April. They included representatives from several development banks, such as the German KfW, the London-based European Bank for Reconstruction and Development and the World Bank via its group member International Finance Corporation (IFC), with all three showing great interest in SDH projects in the Balkans. Additionally, the IFC invited mayors and administrators from cities and municipalities in Albania, Bosnia-Herzegovina, Croatia, Kosovo, Macedonia, Montenegro and Serbia to meet with system suppliers for a workshop in the same city one day thereafter.

“Contract market fluctuates from year to year”
by by Bärbel Epp

2017 was a difficult year for solar district heating supplier Arcon-Sunmark based in Denmark. The collector manufacturer’s turnover dropped from USD 75 million to USD 16.2 million, according to a press release published on 21 March 2018. The uncertain country’s energy policy caused a delay in the launch of new SDH projects in the second half of 2016. To cope with the severe drop in turnover, Arcon-Sunmark let go 20 staff in late 2016 and 16 last October. "At the same time, we have invested in retaining the clear market leader position that we achieved over the years,” Ole Dalby, CEO of Arcon-Sunmark said.

Parabolic trough collector production line shipped to China
by by Bärbel Epp

Absolicon, a Swedish supplier of concentrating solar thermal technology, has recently delivered its first production line to a Chinese company. The equipment to manufacture parabolic trough collectors, which the Swedish business developed in-house, arrived in China in mid-April. The line is now being set up at Heli New Energy Technology, in the country’s southwestern province of Sichuan. The photo, which dates from December 2016, shows the partners involved in the project after they signed the purchase agreement for the system.

Solar industrial heat market – a 2017 survey
by by Bärbel Epp

2017 was a record year for systems providing solar heat for industrial processes (SHIP), since at least 110 large ones adding up to 192,580 m² were put into operation. This has been the result of a survey among 80 turnkey suppliers currently listed on the SHIP Supplier World Map, created by the international Solar Payback project. The total at the end of 2017 stood at approximately 635 SHIP systems, a 21 % increase over the 525 installations which a similar survey showed in early 2017.

Solar cooling demand on the rise in Italy, Spain and the Middle East
by by Bärbel Epp

Sorption chillers may still be a niche market, but Europe’s manufacturers reported rising demand for solar thermal cooling in Italy, Spain and the Middle East in 2017. Solar thermal numbers are on the rise because of three factors: the potential to reduce power consumption, including peak loads; the option to use natural refrigerants, such as water; and the ability to provide demand-responsive heating and cooling throughout the year. The photo shows the solar-cooled headquarters of Agility, a logistics business based in Kuwait.

Building-integrated solar envelopes: barriers to deployment
by by Riccardo Battisti

Active and passive solar systems integrated into building envelopes are key to combatting climate change. However, there are many barriers which confine current solutions to the demonstration stage and prevent them from going mainstream. To increase the size of the market, researchers have examined these barriers as part of Task 56, Building Integrated Solar Envelope Systems for HVAC and Lighting, under the auspices of the IEA Solar Heating & Cooling Programme. Their report will not be available until September 2018, but this article contains a summary of the main conclusions.
