ENDNOTES 02 MARKET AND INDUSTRY TRENDS - SOLAR THERMAL HEATING AND COOLING<br />

Africa and Zimbabwe.<br />

32 Bärbel Epp, “Global view: solar thermal markets transitioning from<br />

residential to commercial,” Solar Thermal World, 3 March 2015,<br />

http://www.solarthermalworld.org/content/global-view-solarthermal-markets-transitioning-residential-commercial.<br />

33 In 2015, the Chinese retail market in the residential sector was<br />

on the decline again, whereas the segment of commercial<br />

projects in cities was growing rapidly, per Hongzhi Cheng,<br />

head of Chinese market research company The Sun’s Vision,<br />

in an interview on Solar Thermal World, 2 October 2015, http://<br />

34 Epp, op. cit. note 9.<br />

35 The project business in Poland grew again in 2015 by 5–10%,<br />

whereas the residential market declined significantly, per<br />

Janusz Starościk, SPIUG, Poland, personal communication<br />

with REN21, March 2016. Poland’s current residential subsidy<br />

scheme, Prosument, is more a solar PV than a solar thermal<br />

scheme; solar thermal applications were accepted only in<br />

combination with a renewable electricity system until August<br />

2015, per Bärbel Epp, “Poland: From renewable heat to renewable<br />

electricity funding,” Solar Thermal World, 6 January 2015, http://<br />

but capped solar thermal subsidy,” Solar Thermal World, 11<br />

36 Bärbel Epp, “Europe: 23 new and upgraded solar district heating<br />

plants of 190 MWth start operation in 2015,” Solar Thermal World,<br />

38 Ibid.; Jan Erik Nielsen, “Solar District Heating in Denmark, Status<br />

2015,” presentation at Task Definition Workshop, Solar District<br />

Heating, Graz, Austria, November 2015.<br />

39 Denmark also has a high share of renewable electricity in summer<br />

that makes it economically advantageous to shut down combined<br />

heat and power facilities that feed into district heating plants, per<br />

Nielsen, op. cit. note 38.<br />

40 Epp, op. cit. note 36.<br />

41 Ibid.<br />

42 The 1,422 m 2 collector field in the German town of Simmern<br />

was finished in December 2015 and will start operation once<br />

the block heating centre is built, with a delay of around six<br />

months, per Rolf Meissner, Ritter XL Solar, Karlsbad, Germany,<br />

personal communication with REN21, March 2016. The German<br />

town of Senftenberg mandated the construction of a 8,300<br />

m 2 gross vacuum tube collector area for district heating, per<br />

Maren Schmidt, Ritter Energy- and Umwelttechnik, Karlsbad,<br />

Germany, press release, 27 February 2016. The German town of<br />

Chemnitz published a tender at the end of 2015 for a solar district<br />

heating system, per Guido Broer, “Kollektorfeld für Chemnitz,”<br />

Solarthemen, 24 December 2015 (in German). The Spanish<br />

company Aiguasol searched for financing for a collector field with<br />

around 4,000 m 2 to feed into the biomass-supplied network La<br />

Marina operated by Ecoenergies Barcelona, per Angel Carrera,<br />

44 EDF Optimal Solutions, France, runs a 1,500 m 2 collector field as<br />

an ESCO to provide heat for the French dairy processor Bonilait<br />

Protéines, which has its factory near the town of Poitiers, per<br />

Bärbel Epp, “Bonilait Dairy: Largest solar process heat installation<br />

in France,” Solar Thermal World, 24 September 2015, http://<br />

www.solarthermalworld.org/content/bonilait-dairy-largestsolar-process-heat-installation-france.<br />

In June 2015 the Indian<br />

ESCO Aspiration Energy realised a 1,000 m 2 collector field for the<br />

Indian Heat Seating Systems, per Viji Suresh, Aspiration Energy,<br />

Chennai, India, personal communication with REN21, May 2015;<br />

Fresnel collectors with 290 m 2 mirror area supply steam to the<br />

Sardinio dairy Nuova Sarda Industria Casearia, per Riccardo<br />

45 The 1 GW th<br />

plant is installed by the California-based company<br />

GlassPoint. The steam is used to heat the heavy crude oil to<br />

improve flow and make it easier to pump it to the surface, per<br />

Bärbel Epp, “Oman: Construction starts for world’s largest solar<br />

steam power plant Miraah,” Solar Thermal World, 20 April 2016,<br />

47 AEE INTEC, Solar Heat for Industrial Processes database, www.<br />

ship-plants.info, as of March 2016, per Wolfgang Glatzl, AEE<br />

INTEC, Gleisdorf, Austria, personal communication with REN21,<br />

March 2016.<br />

48 Solar heat could contribute 8.9 EJ in the residential segment by<br />

2050 and 7.2 EJ in the industrial segment, per IEA, Technology<br />

Roadmap Solar Heating and Cooling (Paris: 2012), https://www.<br />

iea.org/publications/freepublications/publication/Solar_Heating_<br />

Cooling_Roadmap_2012_WEB.pdf.<br />

49 According to the online Solar Heat for Industrial Processes<br />

database (www.ship-plants.info), Chile, China and the United<br />

States lead in volume of installed solar process heat collector<br />

area. Chile boasts the world’s largest solar process heat<br />

installation – the 27.5 MW th<br />

plant at the Gaby copper mine. Austria<br />

and Germany lead in the number of projects, with 23 and 21<br />

projects, respectively. German systems are by far the smallest of<br />

all key market installations, per Bärbel Epp, op. cit. note 43.<br />

50 To tackle the obstacle of having few planning guidelines,<br />

the research group of the IEA Task 49 (Solar Heat in<br />

Industrial Processes) developed and published the so-called<br />

Integration Guideline (http://task49.iea-shc.org/data/sites/1/<br />

publications/150218_IEA%20Task%2049_D_B2_Integration_<br />

Guideline-final.pdf), a step-by-step guide on how to integrate<br />

solar heat in industrial processes, per Wolfgang Glatzl, AEE<br />

INTEC, Gleisdorf, Austria, personal communication with REN21,<br />

April 2016; Bärbel Epp, “Very few countries have policies explicitly<br />

supporting renewable deployment in the industry sector,”<br />

the International Renewable Energy Agency (IRENA) Innovation<br />

and Technology Centre in Bonn, Germany, Solar Thermal World,<br />

55 Ibid.<br />

56 Estimating the number of newly installed solar cooling systems in<br />

2015 is difficult because of the growing number of sorption chiller<br />

manufacturers and of PV cooling systems, and the diversification<br />

of markets in the Middle East, Asia and Australia; thus, it is no<br />

longer possible to assess a global market overview at end-2015,<br />

Berlin, Germany, personal communication with REN21, March<br />

2016.<br />
