Caravel: EU-Programm CIVITAS ('Travelling towards a new mobility')

In CARAVEL ('Travelling towards a new mobility') arbeiten die vier Städte Burgos (Spanien), Genua (Italien), Krakau (Polen) und Stuttgart (Deutschland) im Rahmen des EU-Programms CIVITAS II zusammen. Ziel ist es, unterschiedlichste Ansätze zur Erzielung eines 'nachhaltigen' Verkehrssystems zu erproben. Die Palette der Maßnahmen reicht dabei von Erdgasbussen über Rufbussysteme bis zu überlegungen, eine 'City-Maut' einzuführen. Das Projekt ist im Februar 2005 gestartet und wird vier Jahre dauern. Der Lehrstuhl für Verkehrsplanung und Verkehrsleittechnik ist sowohl auf Gesamt-Projektebene als auch für die Landeshauptstadt Stuttgart für die 'dissemination' der Projektergebnisse verantwortlich. Hierzu gehört die Erstellung einer Projektbroschüre ebenso wie die Herausgabe unterschiedlicher newsletter und die Betreuung der website. Ferner wird der Lehrstuhl im Rahmen von CARAVEL eine Summer University anbieten, die in den Jahren 2007 und 2008 in Budapest, Burgos, Genua und Stuttgart stattfinden wird.

CO2SINK - In-situ Labor zur Untersuchung der Speicherung von Kohlendioxid unter der Erde

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.

Climate Change and Variability: Impact on Central and Eastern Europe (CLAVIER)

Objective: Observational records show that the global climate is changing and ongoing changes are also visible in Central Eastern Europe. About 64Prozent of all catastrophic events in Europe since 1980 can directly be attributed to weather and climate extremes. Climate change projections show even an increasing likelihood of extremes. Certainly negative impacts of climate change will involve significant economic looses in several regions of Europe, while others may bring health or welfare problems somewhere else. Within CLAVIER three representative Central and Eastern European Countries (CEEC) will be studied in detail: Hungary, Romania, and Bulgaria. Researches from 6 countries and different disciplines will identify linkages between climate change and its impact on weather patterns with consequences on air pollution, extremes events, and on water resources. Furthermore, an evaluation of the economic impact on agriculture, tourism, energy supply and the public sector will be conducted. This is of increasing importance for CEEC, which are currently facing a rapid economic development, but also for the European Union as e.g. Romania's and Bulgaria's high vulnerability from extreme events such as floods will impact not only the respective economic goals for joining the EU but also the EU solidarity fund. CLAVIER will focus on ongoing and future climate changes in Central and Eastern European Countries using measurements and existing regional scenarios to determine possible developments of the climate and to address related uncertainty. In addition, climate projections with very high detail will be carried out for CEEC to fulfil the need for a large amount of detail in time and space, which is inherent in local and regional impact assessment.

New sustainable concepts and processes for optimization and upgrading municipal wastewater and sludge treatment (NEPTUNE)

The scope of sewage treatment is changing: Up to date municipal wastewater treatment plants (WWTP) were seen as an end-of-pipe treatment just before discharge, having the aim to avoid eutrophication and hygienic health hazard in surface water. Due to the global demographic trends as well as new legislations (e.g. the Water Framework Directive, WFD) increased focus is put on quantity and quality of effluents: WWTP are more and more seen as interface between sanitation and environment, delivering resources to the environment or human activities (recharge of drinking water reservoirs, recycling of nutrient, efficient energy use). This focus shift has implications on the quality goals set for WWTP products: land requirement, effluent N, P load, effluent pathogen load, energy optimization. New focus: nutrient recycling, micropollutants: ecotoxicology of the effluent energy production. NEPTUNE is focusing on technology solutions allowing to meet present and future standards via upgrading of existing infrastructure (new control strategies with online sensors; effluent upgrading with oxidation, activated carbon or wetland treatment; sludge processing for safe nutrient recycle) as well as via new techniques (fuel cell applications; new oxidative agents; polymer production from sludge). By including pathogen and ecotoxicity aspects into life cycle assessment studies (LCA), the project is helping improve the comparability of various technical options and propose a suitability ranking. The new focus given by the WFD and the emerging interest on organic (eco-)toxic compounds requires characterizing treated effluent and treatment technologies concerning ecotoxicologic aspects and micropollutants. The project is contributing to this discussion by ecotoxicity assessment and micropollutant fate studies.

Large-Area CIS Based Thin-Film Solar Modules for Highly Productive Manufacturing (LARCIS)

Objective: In order for the commercial production of large CIGS modules on the multi-MW scale to be successful, the processes must still be streamlined and optimised taking considering both economical and ecological aspects. This project aims to support the developme nt of this material- and energy-saving thin-film technology so it can gain a foothold in the free PV market. Promising laboratory results will be transferred to large-scale production, where the availability of appropriate production equipment and very hig h material and process yields are of decisive importance. 4 universities, 2 research institutes, and 4 companies will work closely together in order to merge the physical understanding of the processes and the engineering know-how, which are necessary for up-scaling the CIGS technology to a marketable multi-megawatt production volume. We will focus on: (1) very high-quality modules manufactured by coevaporation of CIGS and applying cost-effective methods, ETA up to 14 Prozent on 0.7 m2; (2) the development of Cd-free buffer layers for Cd-free CIGS modules on an area of up to 0.7 m2, ETA up to 12 Prozent; (3) and the development of a mid-term alternative: electrodeposition of low-cost CIS modules with ETA above 10 Prozent (estimated cost about 0.8 E/Wp). We will transfer the Mo back contact sputtering know-how to a specialised European large-area glass coater to provide substrates for both the coevaporation and the electrodeposition approaches. All process developments such as modifications of the back contact, wet- or vacuum-deposited buffer layers, the multi-stage coevaporation of CIGS, or improved Ga incorporation in electrodeposited absorbers will first be tested and evaluated on the laboratory scale. Successful approaches will be up-scaled and transferred to three independ ent commercial CIGS pilot lines located in three different European countries. Novel process and quality control techniques must also be developed and applied to reach these ambitious goals.

A coordination action to prepare European Hydrogen and fuel cell demonstration projects (HYLIGHTS)

Objective: HyLights is a CA facilitating the planning of HyCOM. Focus is an assessment of concluded/ongoing H2/FC demonstration projects and recommendations for the preparation of HyCOM/Lighthouse Projects LP. Although HyLights's assessment focuses on transport stationary and portable H2 applications will be considered if synergies become apparent. HyLights will comprise 3 phases of 12 months each. Phase I includes a methodology definition and assessment, Phase II gaps analysis and development of recommendations and Phase III continuous monitoring. HyLights will need to draw from a network of relevant experts. For this purpose a European Partnership for Hydrogen in Transport EPHT will be established to extend the reach of the European Hydrogen and Fuel Cells Platform HFP. An asset of EPHT will be to include the member states/regions view through a moderation process. Dissemination of the project results will supplement the activity, coherently presenting the European demonstration projects.

6. RP Aquaterra - Understanding river-sediment-soil-groundwater interactions for support of management of waterbodies (river basin & catchment areas) (AQUATERRA)

Objective: Changes in climatic conditions, land use practices and soil and sediment pollution have large-scale adverse impacts on water quantity and quality. The current knowledge base in river basin management is not adequate to deal with these impacts. Austere is both integrating and developing knowledge to resolve this and disseminating it to stakeholders. In the water cycle, soil is a key element affecting groundwater recharge and the chemical composition of both subsurface and surface waters (the latter is additionally affected by sediments). The proper functioning of the river-sediment-soil-groundwater system is linked to key biogeochemical processes determining the filter, buffer and transformation capacity of soils and sediments. Austere aims at a better understanding of the system as a whole by identifying relevant processes, quantifying the associated parameters and developing numerical models of the groundwater-soil-sediment-river system to identify adverse trends in soil functioning, water quantity and quality. The modelling addresses all relevant scales starting from micro-scale water/solid interactions, the transport of dissolved species, pollutants as well as suspended matter in soil and groundwater systems at the catchments scale, and finally the regional scale, with case studies located in major river basins in Europe. With this integrated modelling system, Austere provides the basis for improved river basin management, enhanced soil and groundwater monitoring programs and the early identification and forecasting of impacts on water quantity and quality during this century. Austere is committed to the dissemination and exploitation of project results through structured workshops, dedicated short courses, and the active participation of consortium partners in national and international conferences. A peer review panel supervises the quality and direction of the project.

Integrated Geophysical Exploration Technologies for Deep Fractured Geothermal Systems (I-GET)

The share of renewable energy sources in the European energy balance can be increased by a meaningful contribution of geothermal energy. Since the mining cost (exploration and drilling) to access the resources represents over 60 percent of the total investment, a reduction in mining cost would increase the competitiveness of geothermal energy significantly. This goal can be achieved if we had a way to detect the presence of the fluids inside the natural and/or enhanced geothermal systems before any drilling operation. The project I-GET is aimed at developing an innovative geothermal exploration approach based on advanced geophysical methods. The objective is to improve the detection, prior to drilling, of fluid bearing zones in naturally and/or artificially fractured geothermal reservoirs. This new approach will be tested in four European geothermal systems with different geological and thermodynamic reservoir characteristics: two high enthalpy (metamorphic and volcanic rocks), one middle enthalpy geothermal system (deep sedimentary rocks), and one low enthalpy geothermal system (shallow sedimentary rocks). Petrophysical and geomechanical properties of the investigated rocks will be defined by laboratory measurements. With respect to the high enthalpy sites elastic and electric rock properties will be determined at the steam/liquid transition of the pore fillings. The validity of the laboratory and simulation results will be verified by new field experiments. Seismic and magnetotelluric data will be acquired in the test sites, and new acquisition and processing techniques will be developed to solve problems related to the particular target such as high temperatures, anisotropy, phase condition, etc.. The static and dynamic three-dimensional model of geothermal reservoirs will be reconstructed by means of all the data acquired. The input of the results of new geophysical prospecting into reservoir modelling is a crucial test of the quality of the new exploration method.

Calcium cycle for efficient and low cost CO2 capture in fluidized bed systems (C3-CAPTURE)

Objectives: The project aims on developing a dry CO2 capture system for atmospheric and pressurized fluidized bed boilers. The atmospheric option will be developed towards a pilot plant application. For the pressurized option the project seeks for a proof of principle to determine if the advantages of a pressurized capture system can balance the problems known from existing PFBC systems. The quantifiable objectives are: - Low CO2 capture costs (less than 20 Euro/t for atmospheric, less than 12 Euro/t for pressurized sy stems) - Acceptable efficiency penalty for CO2 capture (less than about equal to 6 percent nel). - greater than 90 percent carbon capture for new power plants and greater than 60 percent for retrofitted existing plants - A purge gas stream containing greater than 95 percent CO2 - A solid purge usable for cement production - Sim ultaneous sulphur and CO2 removal with sulphur recovery option Approach: Limestone is a CO2 carrier. The CO2 can be released easily in a conventional calcination process, well known in the cement and lime industry. By integrating a closed carbonation/calc ination loop in the flue gas of a conventional CFB-boiler, the CO2 in the flue gas can be removed. The heat required for calcination is released during carbonation and can be utilised efficiently (high temperature) in the steam cycle of the boiler. Concent rated CO2 can be generated when using oxygen blown calcination. Because the fuel required for supplying heat for calcination is only a fraction of the total fuel requirements, the required oxygen is only about 1/3 of the oxygen required for oxyfuel process es. The work programme: 1.Definition of the technical and economic boundary conditions 2.Selection and improvement of sorbent materials 3.Lab scale and semi-technical scale process development (experimental work) 4.Technical and economic evaluation 5.Des ign of a 1 MWth Pilot plant.
