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.

Portugal: 35 Years’ Solar Storage Tank Production

Submitted by Baerbel Epp on October 30, 2017
Videira TeamVideira, a family-owned storage tank manufacturer from Portugal, is celebrating its 35th anniversary this year. In 1982, José Oliveira Rocha (sitting) and three of his five children (back) established a small business in Paredes in northern Portugal. In the beginning, it was only him, his three sons and one additional staff member who worked at the 200 m² factory. Meanwhile, production facility has grown to 5,000 m² and the company employs 155 staff, who generated a turnover of EUR 15 million in 2016. Exports made up 70 % of the, all in all, 45,000 water heaters and tanks manufactured last year.

IEA SHC: Most Effective Solar Cooling Storage Technologies

Submitted by Baerbel Epp on September 27, 2017
Scientists from IEA SHC Task 53, New Generation Solar Cooling & Heating Systems, have compared the cost, efficiency and adaptability of solar cooling storage solutions and are now creating a report about the technologies most suitable for a given application. The researchers examined both thermal and electricity storage systems. But whereas the report can soon be used as guidance for choosing the most apt solution to heat and cool buildings, it will not provide a recommendation in favour of storing electricity or thermal energy.

IEA SHC Task 58: “We will need new and innovate designs for heat and mass exchangers”

Submitted by Baerbel Epp on July 18, 2017
Benjamin FumeyThermochemical materials (TCMs) used in storage tanks show higher heat capacities than water and smaller losses over time. They are crucial to an increase in solar use among consumers and the storage of summer heat for the winter season. However, they are also more complex than their water-based counterparts, which require only heat exchangers. Conversely, TCM storage units additionally need mass exchangers to make sorbent-sorbate interaction possible. Research into TCM storage has so far been coordinated by the IEA’s Solar Heating and Cooling Programme’s Task 58, Material and Components for Thermal Energy Storage. Solarthermalworld.org spoke with Benjamin Fumey, Researcher at EMPA – Swiss Federal Laboratories for Materials Science and Technology, about the technology. Fumey heads the Task 58 research group focused on Component Design for Thermochemical Materials. The operation of the specially designed heat and mass exchanger will be explained throughout the interview based on a TCM storage tank with sodium hydroxide as the liquid sorbent. Important technical terms can be found in the glossary at the end of this article.

Renewable Global Futures Report: Experts Divided on Future of Heating

Submitted by Baerbel Epp on July 5, 2017
CoverIs the transition to 100 % renewables at global level a feasible and realistic objective? What share will renewably sourced heat have by 2050? Will the electrification of heat continue? These are three of more than 100 questions which were answered in interviews with 114 experts from all around the world. Interviewees came from NGOs, research institutions, governmental bodies and international organisations. REN21’s Renewable Global Futures Report published in April 2017 summed up their explanations as part of twelve Great Debates. Lead author Dr Sven Teske from the University of Technology Sydney, Australia, presented some of the key findings of the report during a June webinar organised by the International Solar Energy Society. 
 

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.

TASK 45 / 55: Guidelines on How to Design Seasonal Storage

Submitted by Baerbel Epp on August 1, 2016
Bore Hole StorageSeasonal storage is a key component in the transformation of today’s energy industry. Besides storing energy in summer for heating in winter, it can also be used to save waste heat from the industry and to increase the electricity production from biomass CHP plants. Experiences gathered with the technology during case studies were summarised as part of the study Seasonal thermal energy storage – Report on state of the art and necessary further R+D, which was published by Task 45, Large Scale Solar Heating and Cooling Systems, of the IEA SHC programme. Together with the Guidelines for Materials & Construction on the two most common storage types, borehole (see the chart) and water pit, it provides a good overview of the current advancements in this field (all three documents attached). Additional research into the design of seasonal storage will be carried out in follow-up Task 55, Towards the Integration of Large SHC Systems into District Heating and Cooling (DHC) Network. Interested stakeholders have been invited to join the kick-off meeting of Task 55 in Graz, Austria, between 19 and 21 October (see contact details below).

Austria: Decision on Operating Company for Big Solar Graz Expected Soon

Submitted by Baerbel Epp on June 17, 2016
Gleisdorf Solar 2016“Large-scale solar thermal systems in the GW range – an insignificant niche market or the future for solar thermal?” was the official title of a panel discussion at the Gleisdorf Solar conference in Austria in early May. The most important question was: What will be next for the planned 350 MWth solar district heating system called Big Solar in the Austrian city of Graz? “The challenge was to adapt the Danish district heating solutions to Austrian conditions,” emphasised the project’s initiator, Christian Holter (right), Managing Director of S.O.L.I.D. Meanwhile, Christian Stadler (left), Managing Director of one of Arcon-Sunmark’s subsidiaries, Arcon-Sunmark Germany & Austria, represented the company that has stated his own interest in realising Big Solar.
