Bulgaria: Could Solar Thermal Energy Heat All of Sofia?

Submitted by Baerbel Epp on January 4, 2017
Bulgaria solar energy usageThroughout the past decades, Bulgaria’s governments have focused almost exclusively on large conventional energy projects, such as nuclear plants or gas and oil pipelines, whereas small and decentralised renewable energy systems haven’t received much attention from politicians. But the large-scale projects are complex and expensive, so none of them have come to fruition. This is where the most current study by the Bulgarian Institute for Zero Energy Buildings (IZEB) comes in: It sends an important message to all stakeholders by describing a way to keep the entire Bulgarian capital of Sofia and its 1.2 million inhabitants warm without the use of any combustion fuel.
 

Romania: Energy Strategy 2016-2030 to Focus on Gas Supply and District Heating Upgrades

Submitted by Baerbel Epp on December 30, 2016
Energy StrategyThe Romanian Ministry of Energy has published a draft of its Energy Strategy 2016-2030, including an outlook until 2050. The roadmap is based on five strategic objectives, which have been combined to resemble a building (see figure on the left). The roadmap’s authors also propose several key areas for strategic intervention as described below. In 2007, Romania adopted a National Energy Strategy which will last until 2020. The new document will soon be subject to parliamentary debate and is expected to be approved by parliament in the first half of 2017. Both the English summary and the complete Energy Strategy draft in Romanian have been attached to this news article.
 

IEA SHC: Global Technical Solar Process Heat Potential

Submitted by Baerbel Epp on December 29, 2016
Solar Process Heat PotentialThe 191 solar process heat projects which have made it into the online database add up to an installed capacity of 0.11 GWth (0.159 million m²), which is only a small fraction of the potential estimated for this type of application. To quantify the technology’s global opportunities, the researchers from the now-completed four-year Task 49 / IV, Solar Heat Integration in Industrial Processes, analysed the results of several national studies which had tried to determine the potential of solar process heat while considering restrictions such as temperature range and the space available for the systems (see the chart on the left). “For Europe, where mainly non-concentrating collectors had been investigated, the percentage of technical potential for solar process heat related to the total industrial heat demand is around 3 to 4 %,” was the conclusion by the authors of the attached report Potential studies on solar process heat worldwide.

Switzerland: Borehole Storage Regeneration as Solar Thermal’s Ray of Hope

Submitted by Baerbel Epp on December 22, 2016
Solarwärme SchweizOn 24 November, the fifth Solar Heat Switzerland (Solarwärme Schweiz) conference organised by the solar industry association Swissolar, the building services association suissetec and the Federal Office of Energy was held in Lucerne, Switzerland. As 2017 funding for solar heat incentives remains in doubt in several cantons and the priorities of the country´s energy policy haven’t been announced yet, the market outlook for solar thermal has not been very encouraging. But there seems to be a ray of hope in the form of low-temperature collectors for borehole regeneration and solar district heating.

Worldwide: Flat Plate Collector Manufacturer Ranking

Submitted by Baerbel Epp on December 21, 2016
Collector Ranking 2015The 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.

IEA SHC: New PVT System Enhancement Research

Submitted by Baerbel Epp on December 20, 2016
PVT Optimisation ChartAfter seven years, the IEA Solar Heating and Cooling Programme (IEA SHC) is planning to launch another international research cooperation on PVT technology. PVT includes panels which combine photovoltaics and solar thermal into one unit either as glazed or unglazed systems. The first and only task on PVT systems was completed in June 2010. The new one, entitled Application of PVT Collectors and New Solutions with PVT Systems, is in the definition phase. It is expected to start in July 2017 and run for 3.5 years. Interested researchers and industry representatives have been invited to attend a two-day workshop at ETH university in Zurich, Switzerland, from 16 March (1 p.m.) to 17 March (12 a.m.) in order to discuss crucial aspects and the structure of the global initiative.

New Zealand: Over 35 Years of Steel Absorber Collector Production

Submitted by Baerbel Epp on December 19, 2016
Arthur WilliamsonFor more than 35 years, Thermocell collectors have been exclusively manufactured in New Zealand. Developed and commercialised in the late 1970s by Professor Emeritus Arthur Williamson from the University of Canterbury, these patented collector types have been produced in Christchurch ever since. In the peak years of 2005 and 2006, about 12 staff worked for Thermocell in administration, production and installation. As New Zealand’s solar thermal market has declined significantly over the past ten years, only two of those people are left today. “Arthur developed a reliable technology and we are maintaining systems which are more than 30 years old,” confirmed Ian Johns, General Manager of Sunstream Solar, a Thermocell collector reseller and installer from Christchurch. The photo shows Williamson in front of a “heat sheet”, the unique feature of Thermocell systems.

Europe: Solar Keymark Network Approves New Complaint Procedures

Submitted by Baerbel Epp on December 16, 2016
SKN Complaint ProceduresThe 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.
 

IEA Medium-Term Report: Solar Heating and Cooling Not on Track for 2 °C Scenario

Submitted by Baerbel Epp on December 15, 2016
MTRMR 2016The IEA’s Medium-Term Renewable Energy Market Report or MTRMR 2016 again includes a chapter on renewable heating and cooling – and it’s growing in size. The 282-page document published from Singapore on 25 October analyses on 47 pages the current and future market development of four renewable heating technologies: biomass, solar thermal, geothermal and heat pumps. The IEA began to add a renewable heating chapter to its MTRMR in 2013 – back then, it had only 14 pages. The authors of this year’s edition emphasise the fact that onshore wind and solar PV are the only renewable technologies on track for a 2 °C target.
 

Austria Solar: ”It’s about faster and simpler access to solar systems”

Submitted by Baerbel Epp on December 14, 2016
Roger HackstockIn 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.
