Die Verordnung (EU) Nr. 517/2014 über fluorierte Treibhausgase und zur Aufhebung der Verordnung (EG) Nr. 842/2006 ('F-Gas-VO') gibt seit dem Jahr 2015 mittels des 'Phase-down' eine schrittweise Reduzierung der in der EU verwendeten Mengen an teilfluorierten Kohlenwasserstoffen (HFKW) um 79 % bis zum Jahr 2030 vor. Betrachtungen, in welchem Umfang die gesetzlichen Vorgaben zu einer Durchsetzung von HFKW-Alternativen in den einzelnen betroffenen Sektoren in Deutschland geführt haben, gab es bislang nicht. Dieses Vorhaben beleuchtet den Stand der Umsetzung der F-Gas-VO in Deutschland und analysiert die aktuelle Verwendung von HFKW-Alternativen im Kälte-Klima-Sektor. Zudem zeigen Projektionen die Marktdurchdringung der Alternativen in den Sektoren Gewerbekälte, Industriekälte, Transportkälte sowie der stationären und mobilen Klimatisierung bis zum Jahr 2030, wobei Neu- und Bestandsanlagen betrachtet werden. Alle Daten werden mit Hilfe eines Modells berechnet, wobei detaillierte Annahmen zu den künftigen Verwendungsmengen von HFKW sowie deren Alternativen getroffen wurden. Die Gegenüberstellung der in Deutschland zur Verfügung stehenden HFKW-Verwendungsmengen (SOLL-Mengen) und der projizierten HFKW-Mengen (IST-Mengen) in der Kälte- und Klimatechnik zeigt 2018 über alle Sektoren ein deutliches Überschreiten der insgesamt zur Verfügung stehenden HFKW-Mengen, ausgedrückt in CO2-Äquivalenten. Zwar sinken entsprechend der getroffenen Annahmen die HFKW-Verwendungsmengen im IST-Szenario kontinuierlich, allerdings nicht in ausreichendem Maße, um in den Jahren der Reduktionsschritte das SOLL zu erfüllen. Dabei ist auch zu beachten, dass andere Anwendungen außerhalb der Kälte- und Klimatechnik, wie etwa der Einsatz von HFKW als Schaumtreibmittel, Aerosol, Lösemittel oder Feuerlöschmittel, noch nicht eingerechnet sind. Auch der HFKW-Bedarf für die Umrüstung von Bestandsanlagen ist im Modell nicht berücksichtigt. Daneben wird grundsätzlich angenommen, dass fortlaufend technische Innovationen stattfinden, die zur Verringerung der erforderlichen HFKW-Mengen führen. In den einzelnen Anwendungssektoren stellt sich das Bild sehr unterschiedlich dar: Für viele Sektoren wird eine kontinuierliche Überschreitung der zur Verfügung stehenden HFKW-Mengen projiziert. In der Industriekälte ist jedoch mit einem deutlichen Rückgang der Verwendungsmengen zu rechnen und auch andere Sektoren können nach anfänglichem Überschreiten der Mengen ihren HFKW-Bedarf durch den Einsatz von Niedrig-GWP-Kältemitteln deutlich reduzieren (Flüssigkeitskühlsätze und PKWs). Insgesamt können gemäß diesen Berechnungen die EU HFKW-Phase-down Schritte nur zeitverzögert erfüllt werden.
Objective: Solar thermal power plants represent today's most economic systems to generate electricity from solar insulation in them-range in regions like the Mediterranean area. By demonstrating the feasibility of direct steam generation in the absorber pipes European industry and research institutions have gained a leading position in this technology area. A key element foray successful market penetration is the availability of storage systems to reduce the dependence on the course of solarinsolation. The most important benefits result from -reduced internal costs due to increased efficiency and extended utilisation of the power block-facilitating the integration of a solar power plant into an electrical grid-adoption of electricity production to the demand thus increasing revenues Efficient storage systems for steam power plants demand transfer of energy during the charging/discharging process at constant temperatures. The DISTOR project focuses on the development of systems using phase change materials (PCM) as storage media. In order to accelerate the development, the DISTOR project is based on parallel research on three different storage concepts. These concepts include innovative aspects like encapsulated PCM, evaporation heat transfer and new design concepts. This parallel approach takes advantage of synergy effects and will enable the identification of the most promising storage concept. A consortium covering the various aspects of design and manufacturing has been formed from manufacturers, engineering companies and research institutions experienced in solar thermal power plants and PCM technology. The project will provide advanced storage material based on PCM for the temperature range of 200-300 C adapted to the needs of Direct Steam generation thus expanding Europe's strong position in solar thermal power plants.
Die Zirkulation des Antarktischen Zwischenwasser (AAIW) stellt eine entscheidende Rolle in der Atlantischen Meridionalen Umwälzbewegung (AMOC, Atlantic meridional overturning circulation) dar und ist daher entscheidend für das Verständnis des globalen Ozean-Klima-Systems. Die Zufuhr des kalten und salzarmen AAIW in den Nordatlantik beeinflusst die Bildung des Nordatlantischen Tiefenwassers (NADW, North Atlantic Deep Water). Vermutet wird, dass Änderungen in der AAIW Zirkulation während abrupter Kältephasen der letzten 20,000 Jahren zu einer verminderter NADW Bildung beigetragen haben. Spekulativ bleibt aber, ob diese Phasen abgeschwächter AMOC auf eine Zu- oder Abnahme der AAIW Zirkulation zurückzuführen sind. Aufgrund fehlender hochauflösender Klimaarchive ist bislang nur wenig bekannt über einen möglichen AAIW-NADW Kopplungsprozess. Das Ziel der vorliegenden Studie ist daher eine detaillierte Rekonstruktion der AAIW Zirkulation und dessen Einfluss auf die AMOC während der letzten Abschmelzphase und des frühen Holozäns, vor allem während des Heinrich Stadials 1 und der Jüngeren Dryas. Der äquatoriale Westatlantik ist für diese Fragestellung eine höchst spannende Region, da dieser eine Schlüsselregion im globalen ozeanischen Strömungssystem darstellt. Demnach haben Zirkulationsschwankungen innerhalb dieses Gebietes weitreichende Folgen für die Variabilität auch entfernter Regionen in Nord-und Südatlantik sowie das Klima dort. Zwei grundsätzliche Fragen ergeben sich aus der Abfolge der Klimaereignisse der letzten 20,000 Jahre: (1) Welche Veränderungen finden in der Zwischenwasserzirkulation des äquatoriale Westatlantik während Phasen abgeschwächter AMOC statt, und inwieweit stehen diese Veränderungen im Zusammenhang mit einer Zu- oder Abnahme der AAIW Zirkulation. (2) Inwieweit besteht ein Zusammenhang zwischen Änderungen in der AAIW Zirkulation und Klimaänderungen in der Südhemisphäre? Um diese Fragen zu beantworten, werden entlang eines Transekts mehrere hochauflösende Sedimentkerne aus verschiedenen Wassertiefen (bis zu 2000 m) entlang des brasilianischen Kontinentalhanges untersucht. Die Rekonstruktionen basieren hauptsächlich auf isotopengeochemischen Messungen an Foraminiferen, welche durch Spurenelementanalysen ergänzt werden. Dadurch können Herkunft und Transportwege von Wassermassen im Ozean entschlüsselt und Veränderungen der Ozeanzirkulation im Zusammenhang mit Klimaschwankungen der Vergangenheit gebracht werden.
Objective: The integration of DER in the European electricity networks has attracted attention of energy producers, network operators, policy makers and R&D community. In some countries it created a number of challenges for the electricity supply system creating barriers for further expansion of DER. Furthermore, there exists a lack of awareness and understanding of the possible benefits and scope of DER in the electricity system, while environmental goals and security of supply issues ask for solutions that DER could give in the future. The SOLID-DER Coordination Action will tackle the barriers for further integration of DER, overcoming the lack of awareness and fragmentation in EU R&D results by consolidating all European DER research activities. In particular awareness of DER solutions and benefits will be raised in the new Member States, thereby addressing the specific issues and barriers faced here. Consequently the key objectives of the project are: Identify and assess the critical developments, innovations and findings in meeting the R&D needs for large-scale integration of DER. It concerns developments in the field of legislation, regulation, DER support policies, market access, technical breakthroughs in DER supply and enabling technologies. To provide an assessment of costs/benefits and concepts of business models for DER and pro-active networks. Raising awareness of benefits of DER and organising dissemination of knowledge and capacity building in the new MS. The assessment and recommendations of RTD activities and its progress on national, regional, and EU levels will be reviewed and commented by the representatives of the electricity business community. This intensive dialogue will lead to an effective achievement of the overall EU energy policy goals and optimising the penetration of DER. At the same time, it will ensure that electricity networks can guarantee sufficient level of reliability of operation...

Locally available Energy Resources will be used, with a final goal the regional sustainable socio-economic development. Pathways will be invented for maximising Renewable Energy penetration in the region. Ideally, 100 Prozent renewable energy penetration will be pursued for. Through the project, specific Integrated R enewable Energy Systems (1RES) will be proposed for sustainable development of each Region. By the term 1RES it is meant 'o' energy system with an optimal energetic autonomy including food production and if any excesses, energy exports. Energy production a nd consumption at the region has to be sustainable and eventually based mainly on renewable energy sources. It includes a combination of different possibilities for non-polluting energy production, such as modern wind and solar electricity production, as w ell as the production of energy from biomass and any other renewable sources '. Each partner team (in each of the participating countries) will select a pilot rural region and perform the following tasks: 1. Study the today Energy situation in the region ? Study the sources of energy. ? Consumption by sector. Space and time distribution of the consumption. 2. Study the local Energy Potential. Space and time distribution. 3. Define development scenarios of the region. 4. Develop a prototype model (expert sys tem) for introducing in the regions the 1RES s. 5. Propose specific IRESs and development policy to be applied in the region through the developed model (expert system). 6. Socio-Economie and Environmental considerations. 7. Dissemination activities The re sults of the studies for each region will supply the local governments the plans for region sustainable development. The overall project results will provide

ARROWS proposes to adapt and develop low cost autonomous underwater vehicle technologies to significantly reduce the cost of archaeological operations, covering the full extent of archaeological campaign. Benefiting from the significant investments already made for military security and offshore oil and gas applications, the project aims to demonstrate an illustrative portfolio of mapping, diagnosis and excavation tasks. ARROWS approach is to identify the archaeologists requirements in all phases of the campaign, identify problems and propose technological solutions with the technological readiness levels that predict their maturation for exploitation within 3-5 years. The individual technologies are then developed during the course of the project using agile development method comprising rapid cycles of testing and comparison against the end user requirements. To ensure the wide exploitability of the results the requirements are defined and the solutions are tested in two historically significant but environmentally very different contexts, in The Mediterranean Sea and in The Baltic Sea. Both immediate, low risk and long term, high risk developments will be pursued. In particular: - Fast a low cost horizontal surveys of large areas using customised AUVs with multimodal sensing. - Fast and low cost semi-automated data analysing tools for site and object relocation - High quality maps from better image reconstruction methods and better localization abilities of AUVs. - Shipwreck penetration and internal mapping using small low cost vehicles localising using fixed pingers. - Soft excavation tool for diagnosis and excavation of fragile objects. - Mixed reality environments for virtual exploration of archaeological sites. - Monitoring of changes via back-to-the-site missions. The ARROWS consortium comprises expertise from underwater archaeology, underwater engineering, robotics, image processing and recognition from academia and industry.
Small-scale production of local sorghum beer has a long tradition in Sahelian countries. In Burkina Faso the beer called 'Dolo' is deeply embedded in the local culture and consumed with moderation by the Burkinabè population. The craft of Dolo production is exclusively reserved to women, the so-called 'Dolotières', of which a few hundred are active in Ougadougou, Burkina Faso's capital. The production process in the dry country is very firewood intensive: In fact, according to the Ministry of Environment, firewood consumed by the Dolotières accounts for 50Prozent of total firewood consumption in Ouagadougou. The firewood usage in Ouagadougou, in turn, imposes substantial pressures on firewood markets and wood stands in surrounding rural areas, which has tremendous implications for large parts of the country's population that rely on this fuel for their day-to-day cooking purposes. Against this background, Deutsche Gesellschaft für Technische Zusammenarbeit (GIZ) has incorporated one component in its Improved Cooking Stoves program 'Foyers Améliorés Au Burkina Faso' (FAFASO) that aims at introducing improved brewing devices among the brewers through promotion and subsidization activities. Like the mobile improved cooking stoves for households, these stationary stoves are designed to reduce fuel consumption per stove application and to curb smoke emissions. The purpose of this research project is to assess the impacts of this intervention on the firewood consumption in the beer brewing sector. In September 2010, a baseline survey was conducted by a local institute. Together with the International Institute of Social Studies (ISS), RWI will implement a follow-up survey in September 2012 in order to assess the extent to which the Dolotières have adopted the improved brewing devices and in how far this has actually brought down firewood consumption. If possible, a difference-in-difference approach will be applied. Depending on the penetration rate of the brewing devices and the take-up rate among the baseline sample, a further cross-sectional dimension will be added to the identification approach. This research effort will thus show whether focussing on commercial firewood users is an effective way to relieve pressures on the firewood market.
Objective: The main objective of the proposed Network of Excellence (NoE) DER-Lab is to support the sustainable integration of renewable energy sources (RES) and distributed energy resources (DER) in the electricity supply by developing common requirements, quality criteria, as well as proposing test and certification procedures concerning connection, safety, operation and communication of DER-components and systems. DER-Lab intends to strengthen the EC domestic market and to protect European interests on the international standardisation level. A major objective is to establish a durable European DER-Lab Network that will be a world player in this field. The NoE will bring together a group of organisations for the development of certification procedures for DER- components for electricity grids. The NoE will act as a platform to exchange the current state of knowledge between the different European institutes and other groups. The scattered, but high quality research and test facilities will be combined with great benefit for the European research infrastructure DER-Lab will contribute by developing new concepts for control and supervision of electricity supply and distribution and will bundle at European level specific aspects concerning the integration of RES technologies. The absence of European and international standards for the quality and certification of components and systems for DER is a hindrance to the growth of the European market and for European penetration of the world market. It is within the aims of the proposed NoE to reduce these barriers and to work towards common certification procedures for DER components that will be accepted throughout Europe and the world. Obviously this work cannot be done on a national basis. The results of the project and afterwards the output of the network will be a significant contribution to the European standardisation activities and will contribute to the harmonisation of the different national standards.
