Experts from 51 countries discussed the contribution of the heating sector to achieving global climate targets at ISEC 2018 in Graz

370 experts from science, industry and energy policy from 51 countries took part in the International Sustainable Energy Conference (ISEC 2018) held in Graz from 3 to 5 October 2018 as part of the Austrian EU Presidency.

The conference focused on the heating sector and resource efficiency in a networked sustainable energy system. Results offer enormous opportunities for innovative research institutions and companies.

In the public discussion on the transition from a fossil to a sustainable energy system, the energy policy focus is very often only on the electricity sector, which accounts for only 20% of global final energy consumption. Implementation of the agreement reached at the UN climate protection conference in Paris in December 2015 to limit global warming below 2°C is only possible if the heat sector is also rapidly converted to renewable energy sources.

"This will not only be achieved through electrification of the heating sector and power to gas technologies," said Prof. Hans Martin Henning of the Fraunhofer Institute for Solar Energy Systems in Freiburg in his Key-note speech.

In addition to the 5 Key-note speeches by representatives of the European Commission and the International Energy Agency, 76 experts presented and discussed strategies for the decarbonisation of cities and industrial processes as well as measures in energy spatial planning.

A UNIDO workshop, which also took place within the framework of ISEC 2018, offered the opportunity to network with seven energy centers in developing countries.

The conference was organized by AEE - Institute for Sustainable Technologies with the support of the Federal Ministry for Sustainability and Tourism, the Federal Ministry for Transport, Innovation and Technology, the Austrian Climate and Energy Fund, the Province of Styria and the City of Graz.

nachhaltige technologien 02 | 2018

Water is essential for the energy and food sector. The access to energy, energy security and the environmental impact are influenced by the disposability of water. Fossil fuels need water for extraction, transport and processing. Thermal power plants (based on nuclear, fossil fuels, biomass, concentrating solar power) use water for cooling purposes and for hydroelectric plants resilient river currents are crucial. Similarly, production of bio fuels and bio plastics require water for the production processes.

Energy is important for accessing clean drinking water, for watering in agriculture and waste water treatment: pumping of ground and surface water, treatment and transport of water to the end-users as well as cleaning of wastewater in order to recycle it.

Currently water, food and energy systems are dependent but do not interact actively. In Austria national regulations for energy production and distribution exist whereas issues concerning water are regulated on community level. Industrial agriculture and food processing is ruled by companies and multicorporate enterprises. The analysis of the nexus between energy, food and water therefore tries to address these complex and critical subjects in a holistic and systemic way.

Lately, progress in research and analysis led to innovative technologies and integrated approach concerning the above addressed subjects. In the current issue of the magazine “nachhaltige technologien” examples for these the discussed questions are given.

Members of the AEE receive the magazine four times per year. Register now and you will receive the next magazine with its special attachments and the information on the upcoming events straight to your mailbox at home. Membership registration.

Die Dokumentation und Analyse der Marktentwicklung der Technologien zur Nutzung erneuerbarer Energie schafft eine Daten-, Planungs- und Entscheidungsgrundlage für zahlreiche Akteursgruppen in der Politik, der Wirtschaft und im Bereich der Forschung und Entwicklung. In diesem Sinne schafft die vorliegende Marktstudie “Innovative Energietechnologien in Österreich – Marktentwicklung 2017“ diese Grundlagen für die Bereiche feste Biomasse, Photovoltaik, Solarthermie, Wärmepumpen und Windkraft. Neben der Dokumentation von Verkaufszahlen für den Inlandsmarkt und den Exportmarkt werden volkswirtschaftliche Kennzahlen im Bereich der Umsätze, der Arbeitsplätze und der CO2-Effekte dieser Technologien präsentiert.

Die Öl- und Gaspreisentwicklung 2016 und 2017 mit einem nur moderaten Preisanstieg bedingt weiterhin schwierige Rahmenbedingungen für erneuerbare Energietechnologien. Dennoch konnten österreichische Unternehmen in den Bereichen Biomasse, Photovoltaik, Solarthermie, Wärmepumpen und Windkraft im Jahr 2017 einen Umsatz von 4,9 Milliarden Euro erzielen und mehr als 32.000 Personen beschäftigen. Durch die Anwendung dieser innovativen Technologien wurden in Österreich 66,3 Terawattstunden erneuerbare Energie bereitgestellt und klimaschädliche Emissionen im Umfang von 13,2 Mio. Tonnen CO2-Äquivalent vermieden.

Ausgezeichnete Nachhaltigkeit - Sustainability Award für Großforschungsprojekt „SolPol“

Nachhaltigkeit, die sich bezahlt macht: „SolPol“, die Forschungsinitiative zu Kunststoffinnovationen für die Solartechnik unter Leitung der Johannes Kepler Universität, erhielt den Sustainability Award 2018. Der 1. Preis in der Kategorie „Regionale Kooperation (Hochschulübergreifende Projekte)“ wurde vom Wissenschaftsministerium und vom Nachhaltigkeitsministerium in Wien verliehen.

Zehn wissenschaftliche PartnerInnen (AEE – Institut für Nachhaltige Technologien, Universität Innsbruck, WIFO, Kunstuniversität Linz, etc.) und 19 Unternehmen (Borealis, Greiner, AGRU Kunststofftechnik, GREENoneTEC Solarindustrie, etc.) kooperieren seit 2010 in der JKU-SolPol-Forschungsplattform. Sie setzen auf die Potenziale der Vernetzung von Solar- und Kunststofftechnik – zwei Branchen, in denen Österreich traditionell hohe Kompetenz hat. Das Projekt mit einem Budget von 14 Mio. Euro wird vom Klima- und Energiefonds über die Österreichische Forschungsförderungsgesellschaft (FFG) gefördert.

Die Ziele sind ambitioniert: Funktionalität, Lebensdauer und Gewicht von Solarkomponenten sollen durch Kunststoffe, die in der Solarthermie und der Photovoltaik zum Einsatz kommen, verbessert werden.

Die positiven Folgen: die Stärkung und der Ausbau der Position österreichischer Unternehmen der Branche durch polymerbasierende innovative Entwicklungen sowie ein nachhaltiger Beitrag zu erneuerbaren Energien und damit zur Minimierung von Treibhausgasemissionen.


IEA SHC Report: Solar Heat Worldwide – Global Market Development and Trends 2017 / Detailed Market Figures 2016

The report was prepared within the frame work of the Solar Heating and Cooling Programme (SHC) of the International Energy Agency (IEA). The goal of the report is to give an overview of the general trends, to highlight special applications and out standing projects and to document the solar thermal capacity installed in the important markets worldwide. Furthermore, it is the goal to ascertain the contribution of solar thermal systems to the supply of energy and the CO2 emissions avoided as a result of operating these systems. The collectors documented in detail are unglazed collectors, glazed flat-plate collectors (FPC) and evacuated tube collectors (ETC) with water as the energy carrier as well as glazed and unglazed air collectors.

This edition of Solar Heat Worldwide includes for the first time an overview of concentrating solar collectors, which are applied in district heating and for industrial processes.

The data were collected from a survey of the national delegates of the IEA SHC Executive Committee and other national experts active in the field of so larther mal energy. As some of the 66 countries included in this report have very detailed statistics and others have only estimates from experts, the data was checked for its plausibility on the basis of various publications.

The collector area, also referenced as the installed capacity, served as the basis for estimating the contributions of solart hermal systems to the energy supply and reductions of CO2 emissions.

The 66 countries included in this report represent 4.8 billion people, or about 66 % of the world’s population. The installed capacity in these countries is estimated to represent 95 % of the solar thermal market worldwide.
