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.

Driving under the influence of drugs, alcohol and medicine (DRUID)

Objective: As consumption of psychoactive substances such as alcohol, drugs and certain medicines are likely to endanger the drivers aptitude and impaired driving is still one of the major causes for road accidents, some active steps have to be taken to reach the goal of a 50% reduction in the number of road deaths in the EU. The objective of DRUID is to give scientific support to the EU transport policy to reach the 2010th road safety target by establishing guidelines and measures to combat impaired driving. DRUID will - conduct reference studies of the impact on fitness to drive for alcohol, illicit drugs and medicines and give new insights to the real degree of impairment caused by psychoactive drugs and their actual impact on road safety - generate recommendations for the definition of analytical and risk thresholds - analyse the prevalence of drugs and medicines in accidents and in general driving, set up a comprehensive and efficient epidemiological database.

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.

FP6-SUSTDEV, Netzwerk für die Entwicklung einer nachhaltigen Methode zur großangelegten Einführung von Sanitäreinrichtungen in Afrika (NETSSAF)

Ohne einen kurzfristigen erheblichen Fortschritt wird die Welt das Hygieneziel der Jahrtausendentwicklungsziele (MDG) um eine halbe Milliarde Menschen verfehlen. Betrachtet man etwa die subsaharischen Länder Afrikas, dann hat fast zweidrittel der Bevölkerung (64 Prozent) keine ausreichende Versorgung mit Sanitärenanlagen. In den afrikanischen Ländern schwankt die Menge der Wohnungen und Häuser mit Sanitäreinrichtungen zwischen 84 Prozent in den städtischen Gebieten und 45 Prozent in den ländlichen Gebieten. Um bis 2015 das Ziel einer flächendeckenden Wasserversorgung zu gewährleisten, müssen in den nächsten 15 Jahren für 210 Millionen (194 in den ländlichen Gebieten) Menschen zusätzliche sanitäre Einrichtungen gebaut werden. Das Ziel dieser Koordinierungsmaßnahme ist der Aufbau einer multilateralen, interdisziplinären Interessengruppe von subsaharischen und europäischen Fachleuten für die nachhaltige Entwicklung von Sanitäranlagen. NETSSAF fördert internationale Zusammenarbeit zwischen Forschungsinstitutionen, Verbänden, Universitäten sowie Gesellschafts- und Regierungsinteressengruppe in einem europäischen und subsaharischen Zusammenhang mit einer speziellen Ausrichtung auf die Westafrikanischen Länder. Eine beständige Plattform für Experten und Forschung im Sanitärsektor und ein Sachverständigennetzwerk werden eingerichtet, um nutzbringende Forschung und strategische Aktivitäten zu koordinieren, zu bestimmen und zu leiten, mit dem Ziel einerseits ein optimales Verfahren, Wissenslücken und Grenzen für das weitere Vorgehen zu bestimmen und andererseits Vorschläge für die Richtung zukünftiger Forschungen zu unterbreiten. Das Ziel des vorgeschlagenen Netzwerkes ist es ein Vielfalt an innovativen, anwendbaren und wiederholbaren Ansätzen für eine nachhaltige Sanitärentwicklung zu liefern, welche preiswerten Technologien mit einem auf der Kommune basierendem Management und den unterschiedlichen in den Regionen Afrikas vorherrschenden Bedingungen verbindet. Das Hauptergebnis wird die Entwicklung eines partizipativen Hygiene-Management-Unterstützungsinstruments für mehrere Benutzer sein, das für die Endbenutzer darauf abgezielt, sie in die Lage zu versetzen groß angelegte Hygienekonzepte und Technologien anzuwenden und sie den unterschiedlichen Bedingungen, die in Afrika vorherrschen, anzupassen.

SOLATERM - Promotion of a New Generation of Solar Thermal Systems in the Mediterranean Partner Countries (MPC)

The Mediterranean Partner Countries of the European Union are confronted with a rapidly increasing energy demand caused by a growing population especially in cities and increasing living standards. The region has a great potential for the use of renewable energies, notably solar energy due to its high level of solar radiation. However, only a small variety of solar thermal technologies is used in the region. The state of technology and the political support mechanisms vary strongly across the region and in relation to the EU countries, where new solar thermal applications for water and space heating as well as cooling are developed. SOLATERM is an EU-funded project that brings together research institutions, energy agencies, authorities and enterprises from EU and the Southern Mediterranean partners. The project consortium with partners from eight Southern Mediterranean and five EU countries has the aim of promoting the application of a new generation of solar thermal systems in the Mediterranean partner countries. SOLATERM combines the technological know-how of EU research institutions with the specific experiences and knowledge of the Southern Mediterranean partners. The EU partners provide important experiences in developing a successful political framework to boost the use of renewable energy.

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.

SUCCESS - successful travel awareness campaigns and mobility management strategies (MAX)

Objective: Mobility Management (MM) and Travel Awareness (TA) have many advantages as soft policy strategies: they are flexible, adaptable, rapid to implement and offer value-for-money. Many sustainable transport research projects have covered MM and TA, but in isolated projects, limited to larger cities and pilot demonstrations. SUCCESS now offers the chance to link these two areas and exploit their synergies, based on its research areas: A Innovative Approaches in TA B Behaviour Change Models and Prospective Assessment C Quality Management and MM For Smaller Cities D Integrating Planning and MM. They will be linked via horizontal WPs: WP 1 State-of-the-art analysis WP 2 Conceptualisation and specification of research activities WP 3 Monitoring investigations and implementation WP 4 Compiling results WP 5 Dissemination and WP 0 Project Management, Quality Control and Evaluation run in parallel for the duration of the project. Organising the work in this way will deliver excellent results.

Realising Reliable, Durable Energy Efficient and Cost Effective SOFC Systems (Real-SOFC), Realising Reliable, Durable, Energy Efficient and Cost Effective SOFC Systems (REAL-SOFC)

Objective: The aim of the proposed Integrated Project is to solve the persisting generic problems with planar Solid Oxide Fuel Cells (SOFC) in a concerted action of the European fuel cell industry and research institutions. Main topics addressed include decreased ageing, cost effective materials, low cost components and manufacturing processes, highest electricity generation efficiency in pressurised operation and waste heat utilisation. In close co-operation between industry and research institutions the following steps are accomplished: *improved understanding of ageing in planar SOFC stacks considering all modes of operation, including pressurised, long-term testing over 10.000 hrs., thermal cycling up to 100 cycles, and the influences of fuel composition; these results will flow into *adaptation of materials and protective coatings in order to reduce ageing to well below 0,5Prozent/1000 hrs., introduction of requirements from pressurised operation to materials and cell development; the modified materials then are used in *manufacturing of improved components under commercial conditions and subsequent characterisation in long- term and cycling tests. Two proofs-of-concept including laboratory equipment tests will address * the pressurised operation of stacks coupled with gas turbines (including pressurised stack development in the 5 and 50 kW range) and *the utilisation of the high-value waste heat for industrial processes , namely sorption cooling. The project addresses the topics of Life Cycle Analysis as an essential tool for assessing the environmental impact and recycling of the materials used, industrial standardisation as a means of lowering costs, and training and dissemination as a tool of human resource management and gender equality. The structure of the project is similar to the U.S. American SECA programme targeted at decisive cost reductions in SOFC systems.
