Development and validation of technical and economic feasibility of a multi MW Wave Dragon offshore wave energy converter (WAVE DRAGON MW)

Objective: The Wave Dragon is a slack-moored wave energy converter of the overtopping type. It is by far the most powerful wave energy converter and at the same time one of the most energy efficient and economic devices under development today. Since March 2003 a 20kW scale 1:4.5 prototype of a 7MW Wave Dragon has been tested as the world's first floating grid connected wave energy converter. The project will develop the Wave Dragon technology further from the tested all steel-built 20kW prototype to a full size composite built 7MW unit and by testing validate the technical and economic feasibility. The RTD-part of the project will: - Develop Wave Dragon's energy absorbing structure, the low head turbine power take-off system and the control systems. An additional reservoir placed above the existing reservoir level will also be developed. The result of these changes to the overall design will be a significant increase in power production and a reduction in O&M cost. The development of the 7MW unit will be based on the knowledge base established through the tests with the 20kW prototype and the design process will comprise several innovative elements utilizing the O&M experience from the 20kW prototype tests. - Develop cost effective construction methods and establish the optimal combination of in situ cast concrete, post- stressed reinforcement and pre-stressed concrete elements - Develop new supplementary environmental friendly water hydraulic power take-off systems - Demonstrate reliable and cost effective installation procedures and O&M schemes - Establish the necessary basis for design codes and recommendations for floating multi MW wave energy converters. The test program will demonstrate the availability, power production predictability, power production capability and medium to long term electricity generation costs at 0.052EUR/kWh in a wave climate of 24kW/m, which could be found relatively close to the cost at the major part of the Atlantic coast.

Renewable fuels for advanced powertrains (RENEW)

Objective: This project aims to develop, assess and train on various production chains for motor vehicle fuels ligno-cellulosic biomass sources will be used as feedstock to produce synthesis gas from which various vehicle fuels can be derived: CH4, methanol/DME, ethanol (thermo-chemical and enzymatic pathway) and a novel biomass-to-liquid (BTL) fuel. The project will develop and evaluate the respective processing technologies with a view to producing cost effective premium fuels for current and future combustion engines from a wide bandwidth of feedstock. Within 4 vertical subprojects, alternative thermo-chemical gasification, enzymatic fuel production and fuel synthesis processes will be considered, while 2 horizontal subprojects are directed towards technology assessment and training. Two pilot-produced fuels (DME and BTL) will be submitted to extensive motor-tests by 4 leading European car manufacturers within this project. Other fuels will be made available for tests in various other European R&D projects. It is envisaged that this project will lead to the introduction of favourably priced biomass-derived fuels for motor vehicles, from 2010 onwards. Apart from achieving scientific and technological results, RENEW has the vision to develop commonly agreed strategic recommendations, based on an understanding among relevant players in industry, agriculture and research concerning the technological and market potential of different bio-fuels and their production technologies. RENEW is novel and hugely important to Europe. It offers major Kyoto Protocol benefits, enhances the sustainability and security of vehicle fuel supply, and has positive Regional socio-economic impacts. RENEW involves 31 partners, including 7 SME, from 9 EU MS and AS countries. The consortium has the necessary 'critical mass' to achieve its goals and develop the technology to commercial stage beyond the end of the project.

ENG-ENDEMO C, Municipal wood energy center Rottweil

Objective: Electricity production by gasification of 6350 tonnes per year of fuel wood from forestry waste, communal wood waste and energy plantations in a three stage gas generator in the district of Rottweil. 100 ha of short rotation forestry (poplar and other species) will be planted in a first step. The power output amounts to 990 kWe and additional use of waste heat and gas for heating purpose is foreseen. The production amounts to 7,130,000 kWh. A particular attention will be given to the fuel wood logistics and notably to a 3 months capacity fuel wood storage. The payback time is estimated at 15 years. General Information: The 600 m3 silos, gasifier modules, cogeneration and control room are installed underground. This minimizes noise and also enables the trucks to drive over the silos for direct unloading. The woodchips are dried to approx. 25 per cent moisture content in a vertical rotating conical dryer by means of the available heat from the gas plant. The pre-dried woodchips enter the 3 stage EASIMOD 3500 kWh gasifier. The first stage is an underfeed co-current primary reactor producing primary gas with flying charcoal at about 650 deg. C. Gas is then reformed at approx. 900 deg. C in a separate Venturi burner with secondary air inlet and charcoal/activated carbon extraction. Tars and phenols are cracked. The third step is a separate glowing coke reactor which acts as a safety for tars and phenols cracking and as a gas heating value booster. Gas cleaning consists of dry dedusting in multicyclones, followed by a two-step scrubbing (impingement scrubber plus packed scrubber). The gas is cooled down to approx. 20 deg. C and the heat obtained is then used for predrying the fuel in the woodchips dryer. Ammonia washed out in the scrubbing water is stripped in a packed bed stripper. A waste water treatment plant is foreseen. The dryer, gasifier and gas scrubber are conceived as separate frame-mounted modules. The whole plant runs automatically. The electricity produced will be fed into the medium 20 KV voltage municipal grid. The heat recovered simultaneously will be used in a following step for the heating of a nearby village.

Twinning European and South Asian river basins to enhance capacity and implement adaptive integrated water ressources management approaches (BRAHMATWINN)

BRAHMATWINN will enhance capacity to carry out a harmonised integrated water resources management (IWRM) approach as addressed by the European Water Initiative (EWI) in headwater river systems of alpine mountain massifs already impacted from climate change, and to establish transfer of professional IWRM expertise, approaches and tools based on case studies carried out in twinning European and Asian river basins. With altogether eleven work packages (WP) the project addresses all important IWRM issues in a balanced way, including conflict resolution in the trans- boundary twinning Upper Danube River Basin (UDRB) and the Upper Brahmaputra River Basins (UBRB) in Europe and South Asia respectively. In altogether seventy work tasks of the jointly identified WP social and natural scientists in cooperation with water law experts and local stakeholders will realize the project outcomes: (i) an integrated holistic approach and assessment of the transboundary UDRB and UBRB for sustainable IWRM; (ii) integrated indicators to quantify the natural environment and human dimension, selected to assess IWRM vulnerabilities; (iii) an integrated water resources management system (IWRMS) comprising the DANUBIA hydrological model, the river basin information system (RBIS) and the network analysis, creative modelling decision support system NetSyMod; (iv) a set of what-if scenarios, evaluated using the DPSIR approach, and associated adaptive IWRM options tested by means of the IWRMS to mitigate impacts of likely climate change; and (v) IWRM action plans based on the stakeholder negotiation and the governance assessment. The project consortium of altogether fifteen partners from Europe (10 partner) and Asia (5 partner) shares the financial grant requested proportionally and will guarantee the generation of the necessary synergism required to represent the complex system component interaction and to carry out the required knowledge transfer between Europe and Asia.

Models for Assessing and Forecasting the Impact of Environmental Key Pollutants on Marine and Freshwater Ecosystems and Biodiversity - MODELKEY

MODELKEY comprises a mulitdisciplinary approach aiming at developing interlinked and verified predictive modelling tools as well as state-of-the-art effect-assessment and analytical methods generally applicable to European freshwater and marine ecosystems: 1) to assess, forecast, and mitigate the risks of traditional and recently evolving pollutants on fresh water and marine ecosystems and their biodiversity at a river basin and adjacent marine environment scale, 2) to provide early warning strategies on the basis of sub-lethal effects in vitro and in vivo, 3) to provide a better understanding of cause-effect-relationships between changes in biodiversity and the ecological status, as addressed by the Water Framework Directive, and the impact of environmental pollution as causative factor, 4) to provide methods for state-of-the-art risk assessment and decision support systems for the selection of the most efficient management options to prevent effects on biodiversity and to prioritise contamination sources and contaminated sites, 5) to strengthen the scientific knowledge on an European level in the field of impact assessment of environmental pollution on aquatic eco-systems and their biodiversity by extensive training activities and knowledge dissemination to stakeholders and the scientific community. This goal shall be achieved by combining innovative predictive tools for modelling exposure on a river basin scale including the estuary and the coastal zone, for modelling effects on higher levels of biological organisation with powerful assessment tools for the identification of key modes of action, key toxicants and key parameters determining exposure. The developed tools will be verified in case studies representing European key areas including Mediterranean, Western and Central European river basins. An end-user-directed decision support system will be provided for cost-effective tool selection and appropriate risk and site prioritisation.

Catenary Interface Monitoring Coherent sensing technology for electrical railway infrastructure and rolling stock for interoperable cross boundary transportation (CATIEMON)

Objective: In a deregulated EU rail market monitoring of the vehicle and infrastructure interface is mandatory for enhanced availability of operation reducing costs. Especially when a rolling stock is crossing boundaries between independent infrastructure grids, cond ition monitoring becomes crucial. A monitoring tool on OCLs overhead contact lines - for infrastructure managers is needed for an separate measurement of contact force and surface condition of the vehicle current strip. The rolling stock operator needs a complementary device to measure not only the vertical contact force, but moreover the friction force, in order to analyse the vehicle and OCL interface condition. In SMITS a monitoring system for contact force on the interface current collector lt;- gt; c ontact wire has been developed. A sensor technology has been started to explore showing the potential for an extended range of rail monitoring tools. An innovative coherent sensor technology approach shall be investigated and two independent monitoring too ls for vehicle and infrastructure be developed. These shall be validated at new rail tracks specified for TSI interoperable cross boundary transportation: the Ltschberg Basis Tunnel, CH and the HSL Zuid high speed line, NL, both ready for operation in 2007 . Demonstration tests in operation will be performed along the Korridor X infrastructure passing through different countries rail networks. The outcome of the project will enable managers to specify driving conditions for the usage of their infrastructure to avoid excessive wear improving availability. Complementary rolling stock operators can monitor OCL condition giving them an informative argument in case of damage. Condition-dependent user fees as well as threat of penalty will force vehicle and infrast ructure managers to maintain the vehicle and infrastructure interface on a superior level of availability. The operational costs will be reduced and availability of transportation capacity enhanced.

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.

Demonstration of direct Solid Recovered Fuel (SRF) co-combustion in pulverised fuel plants and implementation of a sustainable waste-to-energy technology in large-scale energy production (RECOFUEL)

Objective: The use of Solid Recovered Fuels (SRF) derived from mixed-/mono waste streams is expected to result in a significant contribution to the generation of sustainable energy. The demand for alternative waste treatment is addressed by production and direct co-combustion of SRF in pulverised fuel fired power plants as an environmentally friendly, energy efficient, short-term available and cost effective technical solution. The project assists the implementation of EU policies (energy, environmental, economic and social goals) by sustainable energy production, CO2 emission reduction, preservation of natural resources and abatement of hazardous impacts on the environment due to landfill. The proposed project comprises large-scale demonstration of SRF co-combustion at a 450MWth brown coal/lignite boiler of RWE Rheinbraun AG in a continuous period of at least 12 months with the scope of permanent and reliable operation. A thermal share of 10% is envisaged (25.000 - 50.000 Mg/a SRF) resulting in a direct environmental benefit up to 50.000 Mg/a CO2 by the efficient use of the renewable share of SRF. With successful demonstration the implementation of the SRF co-combustion technology at further comparable and larger units of RWE is envisaged. Operational problems arising during former short-term co-combustion tests with hard coal could be successfully solved by an improved fuel production and a reliable quality control system. The interaction between a reliable quality control, quality management system and the combustion technology makes this technology competitive in the liberalised energy market without any additional subsidy. To achieve the ambitious goals partners of industry and research centres with substantial expertise in the areas covering the whole waste-to-energy chain created a consortium.

Fuel cell power trains and clustering in heavy-duty transports (FELICITAS)

Objective: The FELICITAS consortium proposes an Integrated Project to develop fuel cell (FC) drive trains fuelled with both hydrocarbons and hydrogen. The proposed development work focuses on producing FC systems capable of meeting the exacting demands of heavy-dut y transport for road, rail and marine applications. These systems will be: - Highly efficient, above 60Prozent - Power dense, - Powerful units of 200kW plus, - Durable, robust and reliable. Two of the FC technologies most suitable for heavy-duty transport applic ations are Polymer Electrolyte FuelCells (PEFC) and Solid Oxide Fuel Cells (SOFC). Currently neither technology is capable of meeting the wideranging needs of heavy-duty transport either because of low efficiencies, PEFC, or poor transient performance,SO FC. FELICITAS proposes the development of high power Fuel Cell Clusters (FCC) that group FC systems with other technologies, including batteries, thermal energy and energy recuperation.The FELICITAS consortium will first undertake the definition of the requirements on FC power trains for the different heavy-duty transport modes. This will lead to the development of FC power train concepts, which through the use of advanced multiple simulations, will undertake evaluations of technical parameters, reliab ility and life cycle costs. Alongside the development of appropriate FC power trains the consortium will undertake fundamental research to adapt and improve existing FC and other technologies, including gas turbines, diesel reforming and sensor systems f or their successful deployment in the demanding heavy-duty transport modes. This research work will combine with the FC power trains design and simulation work to provide improved components and systems, together with prototypes and field testing where ap propriate.The FELICITAS consortium approach will substantially improve European FC and associated technology knowledae and know-how in the field of heavv-duty transport.

Biomass Fuell Cell Utility System (BIOCELLUS)

Objective: Energy from Biomass needs highly efficient small-scale energy systems in order to achieve cost effective solutions for decentralized generation especially in Mediterranean and Southern areas, and for applications without adequate heat consumer. Thus fuel cells are an attractive option for decentralized generation from biomass and agricultural residues but they have to meet at least two outstanding challenges: 1. Fuel cell materials and the gas cleaning technologies have to treat high dust loads of the fuel gas and pollutants like tars, alkalines and heavy metals. 2. The system integration has to allow efficiencies of at least 40-50 percent even within a power range of few tens or hundreds of kW. This proposal addresses in particular these two aims. Hence the first part of the project will focus on the investigation of the impact of these pollutants on degradation and performance characteristics of SOFC fuel cells in order to specify the requirements for appropriate gas cleaning system (WP 1-2). These tests will be performed at six existing gasification sites, which represent the most common and applicable gasification technologies. WP 3 will finally test and demonstrate the selected gas cleaning technologies in order to verify the specifications obtained from the gasification tests. The results will be used for the development, installation and testing of an innovative SOFC - Gasification concept, which will especially match the particular requirements of fuel cell systems for the conversion of biomass feedstock. The innovative concept comprises to heat an allothermal gasifier with the exhaust heat of the fuel cell by means of liquid metal heat pipes. Internal cooling of the stack and the recirculation of waste heat increases the system efficiency significantly. This so-called TopCycle concept promises electrical efficiencies of above 50 percent even for small-scale systems without any combined processes.
