Das Projekt "The Deep Sea & Sub-Seafloor Frontier (DS 3 F)" wird vom Umweltbundesamt gefördert und von Universität Bremen, Dezernat 3 Haushalt und Finanzen, Dritt- und Sondermittel durchgeführt. Objective: The Deep Sea and Sub-Seafloor Frontier project (DS3F) provides a pathway towards sustainable management of oceanic resources on a European scale. It will develop subseafloor sampling strategies for enhanced understanding of deep-sea and subseafloor processes by connecting marine research in life and geosciences, climate and environmental change, with socio-economic issues and policy building. Subseafloor drilling and sampling provide two key aspects for understanding how deep-sea ecosystems presently function and how they may respond to global change: (a) an inventory of current subsurface processes and biosphere, and their links to surface ecosystems, utilising seafloor observation and baseline studies and (b) a high resolution archive of past variations in environmental conditions and biodiversity. For both aspects, an international effort is needed to maximise progress by sharing knowledge, ideas and technologies, including mission-specific platforms to increase the efficiency, coverage and effectiveness of subseafloor sampling and exploration. The deep biosphere has been discovered only within the past two decades and comprises a major new frontier for biological exploration. We lack fundamental knowledge about biomass distribution, diversity and physiological activity of deep biosphere communities at life s extremes, and their impact on seafloor and deep sea ecosystems. Similarly, the geodynamic processes fuelling biological activity, and how these processes impinge upon the emission of geofuels, hydrocarbon formation and other resources including seafloor ecosystems, need to be understood. This Coordination & Support Action will develop the most efficient use of subseafloor sampling techniques and existing marine infrastructure to study the geosystem, its effects on the deep biosphere and marine ecosystems, and provide a comprehensive white paper and an open access web portal for a sustainable use of the oceans and a Maritime Policy.
Das Projekt "Messungen und Modellierung von Ozon und aktiven Spezies von Fruehjahr bis Herbst - SAMMOA" wird vom Umweltbundesamt gefördert und von Forschungszentrum Jülich GmbH, Institut für Chemie und Dynamik der Geosphäre durchgeführt. Objective: Problems to be solved: There are still discrepancies between model prediction and observations of the year- round stratospheric ozone decline in mid and high latitudes. In summer, current models still severely overestimate ozone in the polar regions, and this appears as a major deficiency in our ability to model the complete ozone seasonal cycle. The springtime mid-latitude ozone depletion has not been satisfactorily modelled in a quantitative manner. This proposal hence aims at improving our understanding and modelling of ozone loss processes throughout spring and summer, in the northern mid and high latitudes. Scientific objectives and approach: The main scientific objective is to acquire a quantitative understanding of: (i) the mid-latitude ozone depletion accompanying the breakdown of the wintertime polar vortex, especially over Europe, and ii) the Arctic summer ozone deficit and its linkage to midlatitudes. The project relies on using an integrated approach combining ground-based and balloon-borne measurements, global satellite observations, as well as advanced chemical/dynamical modelling and data assimilation. Measurements of ozone, inert gases, or species actively involved in ozone chemistry, are made at three different stations in the Arctic throughout spring and summer. Observational techniques comprise ground-based lidar and infrared spectroscopic measurements, and light-weight balloon-borne instrumentation. Satellite observations complement these local, ground-based and in-situ measurements by allowing to characterise the global, evolving three-dimensional ozone distribution. The satellite data are globally integrated into a transport model through data assimilation. State-of-the-art numerical models are used to investigate the interaction of chemistry and mixing in the spring and summer stratosphere. These models are used to diagnose the ozone loss mechanisms and the overall transport of trace species in spring and summer. Correlative studies of the abundance of various trace species, either modelled or measured, allow to disentangle the effect of mixing from chemical sources and sinks. Expected impacts: The information to be provided by the field campaigns and model studies during SAMMOA will improve the quantification of ozone loss in the stratosphere, a key science priority in support of the Montreal protocol. This project will particularly impact on understanding of ozone depletion in spring and summer, when it is most harmful. It is indeed in the summertime, that human exposure to UV radiation is largest in middle latitudes. Modelling improvements shall result in better assessment and prediction of the ozone trend and recovery in support of regulatory protocols.

Das Projekt "Standardization of Ice Forces on Offshore Structures Design (STANDICE)" wird vom Umweltbundesamt gefördert und von Dr. J. Schwarz durchgeführt. Objective: During the past six years two RTD-projects have been performed by a consortium of seven European partners to investigate ice forces on marine structures. The aim of this work has been to establish new methods for ice load predictions. The work has been supported by the EC under the projects LOLEIF and STRICE. The data compiled by these projects are of great importance for the future development of offshore wind energy converters, OWECS, in the ice-covered seas of Europe. Because the ice forces on marine structures are internationally heavily disputed the present design codes for OWECS as well as for all marine structures in ice-infested waters are not been considered reliable. Therefore, the main objective of this project is to contribute to the development of an international standard for the design of marine structures such as OWECS against ice loads with special emphasis on European sub-arctic ice conditions.
Das Projekt "Die Zukunft der tropischen Waelder als Kohlenstoffsenke" wird vom Umweltbundesamt gefördert und von Universität Göttingen, Forschungszentrum Waldökosysteme durchgeführt. Objective/Problems to be solved: The Amazonian carbon sink exerts a key influence on the global carbon cycle but the sink strength is not very well known. Any changes in the Amazonian sink strength of carbon resulting from changes in climate or land -use will have a significant impact on global climate and are therefore of direct relevance to the formulation of global and European environmental and climate policies. Scientific objectives and approach: The overarching objective of the project is to examine the parameters and mechanism that determine the magnitude and the behaviour of the Amazonian forest carbon sink and to provide improved estimates of the rate carbon sequestration by forest and savannah at a number of sites across the Amazon Basin. The second aim is to advance understanding of the mechanisms of carbon fixation and how this may be constrained by climate variability, availability of nutrients, and changing rates of N deposition. The final goal is to provide estimates of the current and future behaviour of the carbon sink of the Amazon region and disseminate these results to stakeholders. The first package studies climatic controls on the carbon cycle by determining how variations in climate at seasonal and inter-annual time scales, including ENSO events, control fluxes and sequestration rates of carbon. Flux measurements will be carried out at six field sites in different forest types and savannah. The second package studies carbon uptake and release processes to quantify the fate of assimilated carbon. The future of the carbon sink may well be related to the availability of nutrients and soil moisture. The factors, which control the carbon fluxes and carbon pools, will be studied in packages 3 and 4, respectively. Complementary to these measurements long-term historical trends in the forests biomass will be studied by recensusing 41 forest plots along an 2500 km E-W transect and by tree ring analysis. The data collected will be used to develop and calibrate models and develop aggregation techniques. This will allow us to model the basin-wide carbon fluxes for different scenarios to study land use and climate change effects on the carbon sink. Expected impacts: The project will examine controls that determine the magnitude and behaviour of the Amazonian rainforest carbon sink, provide improved estimates of the current rate of carbon sequestration by forest and savannah, and predict likely future behaviour and implications of the sink for global and European carbon management policies.

Das Projekt "CO2SINK - In-situ Labor zur Untersuchung der Speicherung von Kohlendioxid unter der Erde" wird vom Umweltbundesamt gefördert und von Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum durchgeführt. Ketzin ist eine Stadt westlich von Berlin im Land Brandenburg. In ihrer Nähe wurde seit 1960 Erdgas aus Sibirien in unterirdischen Sandsteinschichten zwischengelagert. Diese Erdgasspeicherung wurde vor kurzem eingestellt. Hier soll ein Forschungs- und Entwicklungsprojekt eingerichtet werden, bei dem das Treibhausgas Kohlendioxid (CO2 ) im Untergrund gelagert werden soll. Das Projekt wird vom GeoForschungsZentrum Potsdam koordiniert und von der Europäischen Union mit 8.7 Millionen Euro gefördert. Das Projekt soll helfen, das wissenschaftliche Verständnis der geologischen Speicherung von CO2 weiter zu entwickeln und die im Untergrund ablaufenden Prozesse der CO2 Injektion praktisch zu erforschen. Zunächst werden geologisch-geophysikalisch-geochemische Voruntersuchungen des Standortes und des vorgesehenen Speicherhorizontes sowie eine umfassende Risikoabschätzung vorgenommen um sicherzustellen, dass die Speicherung auch gefahrlos durchgeführt werden kann. Die erforderlichen Bewilligungen des zuständigen Bergamtes, der örtlichen Gemeinde und das Einverständnis der betroffenen Anwohner müssen dazu eingeholt werden. Die künftige Nutzung des Geländes ist Teil eines behördlich bereits genehmigten Bebauungsplans, der auch andere Vorhaben zur Nutzung regenerativer Energie aus Wind, Sonne und Biomasse einschließt. Das CO2 SINK Projekt erlaubt die Weiterverwendung vorhandener Gasspeicher-Infrastrukturen. Geplant ist die unterirdische Injektion von jährlich mehreren 10,000 Tonnen an reinem CO2 für zunächst zwei bis drei Jahre. Das CO2 soll dabei vorwiegend aus regenerativen Biomasse-Energierohstoffen gewonnen werden. Dieses ermöglicht im Prinzip, CO2 aus der Atmosphäre zu entziehen und damit die Treibhausgaskonzentration zu verringern. Unterirdische Erdgasspeicher und geologische Speicher für CO2 in salinen Grundwasserleitern (Aquifere) haben zwei gemeinsame Merkmale: Sie bestehen aus Gestein mit großem Porenraum wie z.B. Sandstein, das von abdichtenden Tonschichten überdeckt ist. Im Untergrundspeicher Ketzin wurde das Erdgas in einer Sandsteinschicht zwischen 250 und 400 Meter Tiefe unter der Erde gelagert. Aus Erkundungsbohrungen und seismischen Messungen weiß man, dass es dort aber noch mindestens eine weitere gut geeignete Speicherschicht in größerer Tiefe gibt. Diese ist rund 80 Meter mächtig und liegt auf einer geologischen Kuppe, die sich bis ungefähr 600 Meter unter der Erdoberfläche aufwölbt. Die Sandsteinschicht fällt nach allen Seiten auf etwa 700 Meter ab und ist von abdichtenden Gips- und Tonschichten überlagert. Um den Untergrund und die bei der CO2 Speicherung darin ablaufenden Prozesse verstehen zu können, ist im Projekt CO2SINK eine umfassende Reihe von wissenschaftlichen Untersuchungen geplant. Usw.
Das Projekt "Ozonvorlaeufer und deren Wirkung in der Troposphaere" wird vom Umweltbundesamt gefördert und von Universität Bremen, Institut für Umweltphysik durchgeführt. Objective/Problems to be solved: Tropospheric ozone has a dual role with respect to climatic changes. Ozone is itself a greenhouse gas and it also plays a key role in the production of the hydroxyl radical (OH), which controls the lifetime of many climatically important tropospheric gases. Tropospheric ozone and OH are produced as a result of photochemical processes, through reactions involving ozone precursors. The proposed project is defined in order to answer three main questions: first, can the surface emissions of ozone precursors, and their variability be accurately quantified? Second, how should the current observations of chemical species be optimally coupled with chemistry-transport models (CTMs) to quantify the global budgets of ozone precursors and ozone ? Third, how do future changes in surface emissions and proposed future scenarios influence the lifetime of greenhouse gases and ozone distribution ? The project will provide a quantitative basis for emissions, distributions and evolution of chemical tropospheric species for discussions related to policies aimed at improving the quality of air or at reduction of greenhouse species anthropogenic emissions. Scientific objectives and approach: The overall objective of the project is to quantify accurately the budget of ozone precursors using a combination of observations and state of the art CTM. The retrieval methods to derive accurately the tropospheric burdens of CO, CH4, NO2 and ozone from observations provided by the IMG/ADEOS and GOME instruments will be improved. High resolution inventories of emissions for ozone precursors will be developed. The ability of several European CTMs to reproduce current distributions will be assessed, through detailed comparisons between model results and observations. The impact of changes in ozone precursors on the tropospheric oxidising capacity and on the distribution of ozone will be quantified. The relative importance of anthropogenic versus natural emissions in the ozone production will be quantified. The inverse modelling approach for quantifying surface emissions will be further developed. These developments will yield an assessment of the accuracy of current inventories. The impact of emission mitigation policies on the distributions of methane and ozone will be quantified.. Expected impacts: The proposed project addresses issues that are central to our understanding of the causes of large-scale air pollution and climate change, and will provide a quantitative basis for reducing the environmental and climatic impact of human activities. The new tools and data bases we will develop will aid the understanding of changes in the composition of the atmosphere and their consequences. The emissions distributions we will optimise could be used as a starting point for discussions on emissions reduction policies...

Das Projekt "Demonstration of a sustainable CHP concept using residues from olive oil production (OLIVEPOWER)" wird vom Umweltbundesamt gefördert und von New Energy Biomasse Hellas GmbH durchgeführt. Objective: The project focuses on the demonstration of an innovative and sustainable CHP concept using residues from olive oil production (olive wastes) as fuel. A first plant based on the new concept will be realised in Greece. The main objective of the project is to demonstrate a closed cycle concept able to reduce landfill problems and emissions and to promote the use of renewable electricity production in Southern Europe. The project will be based on an approach integrating the whole chain (fuel logistics and preparation, energy production, by-product utilisation). An optimised fuel logistic concept will guarantee for a secured fuel supply over the whole year. The fuel will not only be dewatered and dried but also a marketable by-product will be produced. By this means a better fuel quality can be achieved and solid wastes as well as waste- water can be omitted. The development and design of the combustion unit focuses on a technology tailored to the special characteristics of the olive waste.
Das Projekt "Tools for Sustainabiltity Impact Assessment of the Forestry- Wood Chain" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Department für Biologie, Zentrum Holzwirtschaft des Johann Heinrich von Thünen-Institut, Bundesforschungsinstitut für Ländliche Räume, Wald und Fischerei durchgeführt. The objective of EFORWOOD is to develop a quantitative decision support tool for Sustainability Impact Assessment of the European Forestry-Wood Chain (FWC) and subsets thereof (e.g. regional), covering forestry, industrial manufacturing, consumption and recycling. The objective will be achieved by:a) defining economic, environmental and social sustainability indicators ,b) developing a tool for Sustainability Impact Assessment by integrating a set of models ,c) supplying the tool with real data, aggregated as needed and appropriate,d) testing the tool in a stepwise procedure allowing adjustments to be made according to the experiences gained,e) applying the tool to assess the sustainability of the present European FWC (and subsets thereof) as well the impacts of potential major changes based on scenarios,f) making the adapted versions of the tool available to stakeholder groupings (industrial, political and others).The multi-functionality of the FWC is taken into account by using indicators to assess the sustainability of production processes and by including in the analysis the various products and services of the FWC. Wide stakeholder consultations will be used throughout the process to reach the objective. EFORWOOD will contribute to EU policies connected to the FWC, especially to the Sustainable Development Strategy. It will provide policy-makers, forest owners, the related industries and other stakeholders with a tool to strengthen the forest-based sector's contribution towards a more sustainable Europe, thereby also improving its competitiveness. To achieve this, EFORWOOD gathers a consortium of highest-class experts, including the most representative forest-based sector confederations.EFORWOOD addresses with a high degree of relevance the objectives set out in the 3rd call for proposals addressing Thematic Sub-priority 1.1.6.3 Global Change and Ecosystems, topic V.2.1. Forestry/wood chain for Sustainable Development. Prime Contractor: Stiftelsen Skogsbrukets Forskningsinstitut, Skogforsk; Uppsala; Sweden.
Das Projekt "Solar Steam Reforming of Methane Rich Gas for Synthesis Gas Production (SOLREF)" wird vom Umweltbundesamt gefördert und von Deutsches Zentrum für Luft- und Raumfahrt, Institut für Technische Thermodynamik, Abteilung Systemanalyse und Technikbewertung durchgeführt. Project main goals: The main purpose of this project is to develop an innovative 400 kWth solar reformer for several applications such as Hydrogen production or electricity generation. Depending of the feed source for the reforming process CO2 emissions can be reduced significantly (up to 40 percent using NG), because the needed process heat for this highly endothermic reaction is provided by concentrated solar energy. A pre-design of a 1 MW prototype plant in Southern Italy and a conceptual layout of a commercial 50 MWth reforming plant complete this project. Key issues: The profitability decides if a new technology has a chance to come into the market. Therefore several modifications and improvements to the state-of-the-art solar reformer technology will be introduced before large scale and commercial system can be developed. These changes are primarily to the catalytic system, the reactor optimisation and operation procedures and the associated optics for concentrating the solar radiation. For the dissemination of solar reforming technology the regions targeted are in Southern Europe and Northern Africa. The potential markets and the impact of infrastructure and administrative restrictions will be assessed. The environmental, socio-economic and institutional impacts of solar reforming technology exploitation will be assessed with respect to sustainable development. The market potential of solar reforming technology in a liberalised European energy market will be evaluated. Detailed cost estimates for a 50 MWth commercial plant will be determined.
Das Projekt "Biomass fluidised bed gasification with in situ hot gas cleaning (AER-GAS II)" wird vom Umweltbundesamt gefördert und von Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg durchgeführt. Objective: The project aim is a low-cost gasification process with integrated in-situ gas cleaning for the conversion of biomass into a product gas with high hydrogen concentration, high heating value and low tar/alkali/sulphur concentration in one process step for s ubsequent power production. The proposed process uses in-situ CO2 capture (AER, Absorption Enhanced Reforming). It is more efficient than conventional gasification due to (i) the in-situ integration of the reaction heat of CO2 absorption and water-gas shif t reaction heat (both exothermic) into the gasification and (ii) the internal reforming of primary and secondary tars, which cuts off the formation of higher tars. Thus, the chemical energy of tars remains in the product gas. The product gas after dust rem oval can directly be used in a gas engine for electricity generation. Due to the low operation temperature (up to 700 C) and due to CaO-containing bed materials, the proposed process allows the use of problematic feedstocks such as biomass with high minera l and high moisture content, e.g. straw, sewage sludge, etc., leading to an increased market potential for biomass gasification processes. Screening/development of absorbent materials with high attrition stability and tar cracking properties will be carrie d out. Analysis of tar formation/decomposition process will be studied in a lab-scale fixed bed reactor and a 100 kWth circulating fluidised bed reactor (continuous mode). With the acquired data, the 8 MWth biomass plant at Guessing, Austria, will be opera ted with absorbent bed material in order to prove the feasibility of a scale-up and to assess the economical aspects of the process. In order to point out the market potential, the cost reduction of the AER technology will be quantified in comparison with the conventional gasification power plant. Expected results will be: (i) a broad knowledge of the proposed process and (ii) a low-cost technology for biomass gasification with subsequent power production.
