SHC 2017: Largest experts’ meeting on integrated solar heating and cooling

Submitted by Baerbel Epp on November 8, 2017
SHC2017_1500 experts from more than 50 countries attended the 5th International Conference on Solar Heating and Cooling (SHC) in Abu Dhabi, UAE, from 30 October to 2 November 2017. It was the first time that this biennial conference by the IEA’s Solar Heating and Cooling Programme had been organised jointly with the Solar World Congress by the International Solar Energy Society (ISES). The new partnership resulted in 2017’s largest experts’ meeting on integrated SHC solutions for buildings, industry, cities, regions and utilities, and in over 300 presentations.

Slovenia: On the Path to Renewable District Heating

Submitted by Baerbel Epp on October 2, 2017
Rok SunkoDistrict heating networks supplied by renewable energy sources (RES) are widely recognised today as one of the most effective ways to decarbonise the heating sector. The EU’s CoolHeating project has been supporting the implementation of small, modular renewable heating and cooling grids for towns in southeastern Europe by transferring knowledge from leading countries such as Austria, Denmark and Germany to newcomers, for example, Bosnia-Herzegovina, Croatia, Macedonia, Serbia and Slovenia. It has also led to the publication of a handbook – Small modular renewable heating and cooling grids – available in seven languages (see the attached PDFs). Solarthermalworld.org talked to Rok Sunko (see photo) from one of the project partners, Skupina Fabrika about current developments and the outlook of RES district heating in Slovenia. The company is a Slovenian-based R&D business focusing on renewables, IT solutions and branding.

IEA SHC Task 52: Solar Thermal’s Role in 2050 Energy Mix

Submitted by Baerbel Epp on September 29, 2017
Collector Installation in HamburgWhat role solar thermal will play in the energy sector in 2050 is one of the principal questions that the international Task 52 research project Solar Heat and Energy Economics in Urban Environments intends to answer. As part of this IEA Solar Heating & Cooling Programme task, Denmark’s Aalborg University chose four major solar thermal countries in Europe – Austria, Denmark, Germany and Italy – to model their 2050 solar share in national heat production. The university’s estimates range from 3 to 12 % based on country and scenario, which would require 4 to 175 million m² of collector area in each of the four nations. The solar share of all four was rather similar in high penetration scenarios, although climate, energy demand and network design vary significantly. That’s why the researchers from Aalborg concluded that “the findings can be applied to a variety of energy systems, including in countries that are not directly part of this study.” They also underlined the importance solar thermal could have in reducing pressure on scarce resources such as biomass.

Lithuania: Can Solar Thermal Beat Low Biomass Heat Prices?

Submitted by Baerbel Epp on August 14, 2017
Lithuania District HeatingWith biomass prices on the rise, solar district heating could become profitable in Lithuania. But without investment grants, payback periods were still too long, it said in the conclusion of a 2015 SDH market study by LEI, the Lithuanian Energy Institute (see the attached document in Lithuanian). The photo shows the country’s first SDH system set up in 2011. Installed on the roof of the boiler house, it preheats water for a wood chip boiler in the district heating station of Dūkštas, a town in eastern Lithuania. The demonstration unit with 82 m² of vacuum tube collectors received funding from international organisations.

Denmark: Concentrating Solar Collectors for District Heat in Northern Europe

Submitted by Baerbel Epp on August 11, 2017
BronderslevBrønderslev, a Danish municipality with a population of 12,500, is setting up a multi-purpose renewable heat plant for their district heating network. So far, local utility Brønderslev Forsyning has been operating seven gas-fired combined heat and power (CHP) plants and two gas boilers to produce 130 GWh of heat each year. In the future, most of the yearly district heating demand is planned to be met by a new Organic Rankine Cycle (ORC) unit which receives its energy from two wood chip boilers with 10 MW each and from a 16.6 MWth parabolic trough collector field with a mirror area of 27,000 m².

Solar Thermal Shows Highest Energy Yield Per Square Metre

Submitted by Baerbel Epp on July 31, 2017
Area Yield ComparisonThe annual energy yield per square metre is much higher for solar collectors than for other renewable technologies, as the figure on the left shows. Compared to PV, solar collectors produce, on average, three times as many kilowatt-hours. Compared to biomass or bioethanol, output is in average as much as 43 times their yield. The chart shows end energy production and compares directly thermal and electric kilowatt-hours. The grey part of each bar marks the deviation in yield based on different estimates. The absolute values can be found in a table at the bottom of this article.

Egypt and Jordan: SHAMCI to Give New Impetus to Arab Markets

Submitted by Baerbel Epp on July 13, 2017
SHAMCI Workshop May 2017The implementation of SHAMCI, the Solar Heating Arab Mark and Certification Initiative, could help expand the solar thermal market in both Egypt and Jordan. On 15 and 16 May 2017, a workshop held at the headquarters of RCREEE (Regional Center for Renewable Energy and Energy Efficiency) and on the premises of NREA (New and Renewable Energy Authority of Egypt) in Cairo offered experts, market observers and stakeholders from both countries a platform to discuss requirements for implementing SHAMCI at national level. Solarthermalworld.org spoke to Lotus Shaheen, who works at SHAMCI’s secretariat, about the results of the workshop and the next steps by the regional initiative.

China: Sunrain Finalises Strategic Cooperation Agreements

Submitted by Baerbel Epp on June 30, 2017
Natural Ressources CanadaThe Chinese Sunrain group, the world’s biggest collector manufacturer, is broadening its product portfolio to include large-scale solar thermal plants. Sunrain had already made the first step towards globalising its strategic partnerships by establishing a joint venture with Danish-based Arcon-Sunmark in June 2016. It has now concluded a cooperation agreement with CanmetEnergy in Canada with the aim to develop solar district heating systems using borehole heat storage fields for seasonal storage in China. Canada’s Minister of Natural Resources Jim Carr (back row 2nd from left) oversaw the signing of the agreement during his visit to China in June 2017. The agreement was signed by Xinjian Xu, Founder and Board Chair of Sunrain Solar Energy (front right) and Frank Des Rosiers, Assistant Deputy Minister of Natural Resources Canada’s Innovation and Energy Technology (front left).

Global Status Report 2017: Key SHC Data on Markets and Policy

Submitted by Baerbel Epp on June 22, 2017
GSR 2017 SHC ChapterREN21’s Renewables 2017 Global Status Report (GSR) shows how the 20 largest solar thermal markets in the world developed in 2016 (see the chart on the left). Significant growth was reported from Denmark (84 %), Mexico and India (6 % each). Except for the Danish market, last year was a challenging one for key European sales countries because of factors such as low oil and gas prices, declining demand from homeowners and reduced interest in solar thermal among installers. Consequently, there has been a notable decrease in market size in Poland (-58 %), France (-35 %), Austria (-19 %) and Germany (-8 %). The GSR 2017 was first presented at the beginning of June during the Clean Energy Ministerial in Beijing.

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.
