Sector coupling still at an early stage

Submitted by Baerbel Epp on July 18, 2018
‘Sector coupling’ has become one of the most well-known terms to describe the transformation of energy markets. It had originally been created for models that use surplus renewables, such as wind and solar electricity, to provide heat and power new means of transport. International organisations – for example, REN21 and IEA – have since established more general definitions and charts to illustrate the process. The figure on the left-hand side is taken from a presentation given by Paolo Frankl, Head of the IEA’s Renewable Energy Division, at the Mexirec Conference in Mexico last September.

Water-energy nexus in industrial sector

Submitted by Baerbel Epp on July 9, 2018
Water and energy are the most important resources globally. The term ‘water-energy nexus’ was coined to underline their close connection, and the phrase has become increasingly popular with international environmental organisations. In mid-June, a new research platform, Solar energy in industrial water and waste water management, was launched by the IEA Solar Heating and Cooling Programme to analyse the link between water and energy across the industrial sector. The kick-off meeting is scheduled to take place between 1 and 2 October in Graz, Austria.

Land secured for Big Solar Graz

Submitted by Baerbel Epp on June 25, 2018
SilkeborgBig Solar Graz has reached a significant milestone by purchasing the land on which to construct a solar field and a seasonal storage system. In mid-June, the project partners told the local press that they had bought 55 hectares in the south of Graz, in the Austrian state of Styria, between the city’s airport and the A9 motorway. A flyer by the region’s public utility, Energie Steiermark, stated that the area was large enough to accommodate a 220,000 m² solar field (154 MWth) and 900,000 m³ of seasonal storage, including three ponds. It has been modelled on the world’s biggest solar district heating plant to date, a 110 MWth installation in the Danish town of Silkeborg (see photo).

Three labels in Europe – what are the differences?

Submitted by Baerbel Epp on June 22, 2018
collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right)Labels and trademarks should give the end-consumer a clear feedback on the quality and performance of the labelled product. Currently there are three labels available for solar products or solar assisted heating systems in Europe, so there is an increasing need to explain the differences to market players as well as customers. The chart above shows the two voluntary collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right) which is obligatory for water, space and combi heaters under the Energy Labelling (ELD) and the Ecodesign (EDD) Directives  since September 2015. 

Rising demand for solar heat in large buildings and industry

Submitted by Baerbel Epp on June 6, 2018
SHW 1By the end of 2017, the market for solar heating and cooling had grown by 472 GWth, which again made it the largest for solar energy in the world. The one for photovoltaic systems gained 402 GWp to become the second-largest, and 5 GWel was enough for concentrating solar power to rank third, according to the latest Solar Heat Worldwide report. The report also highlights the rising use of megawatt-class solar heating and cooling solutions for large public and residential buildings, as well as factories. It was launched at the end of May by the IEA Solar Heating and Cooling Programme (IEA SHC). Lead author is the Austrian research institute AEE INTEC.

SDH prefeasibility studies in Bosnia and Croatia

Submitted by Baerbel Epp on May 29, 2018
Source: CoolHeatingIn early 2016, EU-funded CoolHeating began using the know-how acquired during best practice projects in Austria, Denmark and Germany to help with the implementation of small modular renewable heating and cooling grids in southeastern Europe. In mid-March, the CoolHeating partners published seven prefeasibility studies of district heating and cooling across five municipalities in Bosnia and Herzegovina, Croatia, Macedonia, Serbia and Slovenia. Because of geographical features, most projects favoured biomass, but solar thermal does play a crucial role in the proposals created for the Bosnian town of Visoko (see map) and the Croatian city of Ozalj.

Record participation at SDH 2018 in Graz

Submitted by Baerbel Epp on May 3, 2018
Photo: Climate and Energy FundThe 5th International Solar District Heating Conference, which took place in Graz, Austria, in mid-April, brought together 350 experts from 33 countries. It had twice as many attendees as the previous one in Billund, Denmark, in 2016 and attracted representatives from several development banks, such as the German KfW, the London-based European Bank for Reconstruction and Development and the World Bank via its group member International Finance Corporation, or IFC. The photo shows the conference’s supporters and its three organisers, namely Christian Fink (second from left), Austrian research institute AEE INTEC; Thomas Pauschinger (fifth from left in the back), German research institute Solites; and  Werner Lutsch, Managing Director of the German Heat & Power Association, or AGFW for short (second from right).

German associations partner up to promote sustainable cooling

Submitted by Baerbel Epp on April 27, 2018
Logos solar coolingIn early 2018, two German organisations agreed on a joint membership model to promote solar thermal air conditioning and cooling, a niche market in the country. The cooperation between the Green Chiller Association for Sorption Cooling and the Central Association for Refrigeration, Air Conditioning and Heat Pumps, or ZVKKW for short, is hoped to popularise innovative and sustainable cooling solutions. According to a survey among members of the Green Chiller Association, some companies have shifted away from solar-powered sorption cooling because they consider systems combining solar PV and split air conditioning units to have greater economic benefits, especially if the cooling season is short. Others are increasingly using waste heat to run sorption chillers. 

Solar industrial heat market – a 2017 survey

Submitted by Baerbel Epp on April 26, 2018
Image: solar-payback.com/suppliers2017 was a record year for systems providing solar heat for industrial processes, since at least 110 large ones adding up to 192,580 m² were put into operation. This has been the result of a survey among around 80 turnkey suppliers currently listed on the SHIP Supplier World Map, created by the international Solar Payback project. The total at the end of 2017 stood at approximately 635 SHIP systems, a 21 % increase over the 525 installations which a similar survey showed in early 2017.

World Sustainable Energy Days 2019, Wels

Submitted by Baerbel Epp on April 19, 2018
The World Sustainable Energy Days (WSED) are one of Europe’s largest annual conferences in this field. The 2019 conference will take place from 27 February to 1 March in Wels/Austria. Energy efficiency and renewable energy are key to boost the economic competitiveness of the EU, its member states, regions and individual businesses. Resulting economic growth provides jobs and the ability to invest in the further progress of the clean energy transition to the benefit of all citizens. Clean energy for economic competitiveness and how to make the clean energy transition work for business, planet and people will therefore be core themes of the World Sustainable Energy Days 2019. The event will feature policies, technology innovation and market development. It offers a unique combination of conferences and interactive events. The annual conference brings together more than 600 delegates from over 50 countries from business, public sector and the research community.
