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.

IEA SHC: Free Pre-Sizing Tool for Solar Heating and Cooling

Submitted by Baerbel Epp on July 14, 2017
PistacheIn 2015, Task 48 – Quality Assurance & Support Measures for Solar Cooling – came to an end. One of the activities of this IEA Solar Heating & Cooling Programme task was the creation of PISTACHE, a tool for professionals who need to pre-size solar cooling, heating and domestic hot water installations and assess their estimated performance. As part of the Habisol programme, the development of the tool by French organisations Tecsol and INES during the MeGaPICS project received additional funding from the French National Research Agency. It is available as a free download in English and French on the website of Task 48.
 

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.
 

IEA SHC Task 54: Investigating Cost Factors Along the Value Chain

Submitted by Baerbel Epp on May 22, 2017
Task 54 RWTH AachenResearchers have worked intensively for one-and-a-half years across national borders to find ways of reducing the costs of solar thermal systems and making them more attractive to end users. The members of Task 54 of the IEA Solar Heating and Cooling Programme, Price Reduction of Solar Thermal Systems, have discussed the effects of standardised product designs or changes in product offerings on cost structures. They have also analysed the entire value chain from component manufacture to system assembly and installation to help identify cost-cutting potential. This is the first time that methods of Process Cost Analysis are being adapted for the solar thermal business. “The share of overhead (e.g. marketing, sales, logistics, quality management and maintenance) has increased significantly, from 30 to 60 % of total product expenses over the last 50 years. This means we will have to investigate the relationship between technology, product portfolio and overhead,” explained Wolfgang Kramer, Head of the Solar Thermal Heating Systems Department at German-based Fraunhofer ISE. “To this end, the process cost analysis provides important quantitative information.” For example, the chart illustrates the issue of having a wider product portfolio and its impact on competitiveness and profitability. The model is currently being adapted for the solar industry in Task 54 as part of German research programme TEWIsol.

IEA SHC: How to Turn Historic Structures into Nearly Zero Energy Buildings

Submitted by Baerbel Epp on May 17, 2017
Villa CastelliMore than one-fourth of all residential buildings in Europe date from before 1945. Over the past decade, preservationists have taken to the idea of renovating historic structures in an energy-efficient manner. The planned IEA SHC task titled Deep Renovation of Historic Buildings Towards Lowest Possible Energy Demand and CO2 Emission intends to find the best solutions to this challenge. The photo shows the Villa Castelli at Lake Como in Italy. The energy requirements of the building have been reduced and the remaining demand has been met by a heat pump and PV-generated electricity.

IEA SHC: New Task to Push Emerging PVT Industry

Submitted by Baerbel Epp on May 15, 2017
Inventors and start-ups have been trying to combine photovoltaic and solar thermal collectors into one product for many years. Finally, a new industry seems to be emerging. The IEA SHC task Application of PVT collectors and new solutions with PVT systems, which is currently being defined, intends to become the go-to platform for the young technology. It is scheduled for approval by the IEA SHC executive committee in November 2017 and is planned to start in January 2018. The first Task Definition Meeting in Zurich, Switzerland, in May attracted great interest from the industry.
 

Netherlands: Solar Thermal Benefits from SDE+ Solar Heat Tariff

Submitted by Baerbel Epp on May 1, 2017
District Heating Workshop NetherlandsIn the Netherlands, solar district heating plants with a capacity of 140 kWth or above can benefit from a feed-in tariff scheme called SDE+, which pays a certain amount per kWh of energy. Under the scheme, operators of renewable energy plants can apply for a subsidy to bridge the gap between market price and cost of energy production. Consequently, interest was high when a workshop about solar district heating (SDH) took place in mid-April 2017. It attracted around 50 people from the district heating and the solar thermal industry, consulting businesses and the government. Organised jointly by Dutch district heating organisation Warmtenetwerk, Holland Solar and the Netherlands Enterprise Agency, RVO.nl, the workshop featured a presentation on SDH in Denmark – held by Jan Erik Nielsen from PlanEnergi and based on results from Task 45 and 55 of the IEA Solar Heating and Cooling Programme – and provided information about the national subsidy scheme, thermal storage technologies as well as the only DH plant in operation in the Netherlands to date.

IEA SHC Task 50: LightingRetrofitAdviser.com for Investors and Planners

Submitted by Baerbel Epp on April 6, 2017
IEA SHC Task 50A redesign of lighting systems in office or public buildings helps to save electricity and improve lighting quality, as the office building of the Austrian company Bartenbach on the photos shows. However, lighting systems are rarely upgraded: For example, in Germany, retrofits can only be found in 3 % of the existing building stock and 75 % of lighting systems are out of date, as they are older than 25 years. To support planners and investors in their decision on what would be the most apt lighting retrofit, the researchers of Task 50 of the IEA Solar Heating and Cooling Programme, Advanced Lighting Solutions for Retrofitting Buildings, have launched a website called www.lightingretrofitadviser.com and an app for Android and iOS devices. Both provide stakeholders with information about successful case studies of lighting retrofits in buildings, a database of technologies as well as tools, for example, to give direct onsite support for decision making, whether it is sensible to retrofit a lighting system. A webinar on 21 March explained all the services and features of the new website and app. A recording of it is available online.
