Offshore Renewable Conversion systems are mostly at the pre-commercial stage of development. They comprise wave energy and tidal stream converters as well as offshore wind turbines for electrical generation. These devices require research to be undertaken at a series of scales along the path to commercialization. Each technology type is currently at a different stage of development but each one also needs specific research infrastructures to facilitate and catalyze commercialization. The aim of this project is to coordinate research and development at all scales (small models through to prototype scales from Laboratory through to Open Sea tests) and to allow access for researchers and developers into facilities which are not available universally in Europe. The linking together of facilities at different scales together with the incorporation of test facilities for components such as power take-off systems, grid integration, moorings, environmental tests will ensure a focusing of activities in this area. MaRINET brings together an Infrastructure with 42 Facilities from 28 Partners spread across 11 EU countries and 1 ICPC, Brazil. It also brings together a network of expertise in the Offshore Marine Renewable Energy sector with experience at all scales of offshore technology research and development. MaRINET offers over 600 weeks of access to 300 projects and 800 external users. The majority (77%) of the MaRINET budget has been targeted in the areas most prioritized in the EC Call such as networking, training, dissemination and transnational access.

SmILES zooms in simulation and optimisation of smart storage in local energy systems for increasing the understanding and transparency of innovative multi-energy projects. Setting up a shared data and information platform and effective dissemination of related results will contribute to competence building. The objective is to obtain fundamental knowledge about linking and optimising heterogeneous energy carriers and systems including storage and renewable energy technologies from local to national level. Furthermore guidelines for modelling and optimising such systems on European level are developed. These guidelines are derived from knowledge of different energy system configurations (SC), which combine heat and electrical power with storage. The SCs are selected to favour a high relevance for replication throughout Europe including e.g. urban quarters, rural township or industrial environment. This requires the development of a harmonised rich format describing hybrid energy systems and study cases for various scenarios. Different technologies are used to exchange models, allow cross-checks and validate results of simulation and optimisation. A catalogue of best practices of modelling, operating and integrating multi-energy systems is compiled and intended to serve as guideline for stakeholders. Key success factors and barriers from a socio-technical point of view are identified aiming at the reduction of technological gaps and successful implementation of best practices in a socio-economic context. Thus, SmILES will proof the benefit of a hybrid combined heat- and electrical power systems with storage capabilities and deploy the added value of storage integration in future energy systems. Supplementing the research activities, a long-lasting framework across EERA JP borders is set up by the consortium for extending storage integration technologies by linking other EERA members, stakeholders, energy supplier and industry.

Renewable energies have often problems in order to provide a stable and reliable power supply, as they often depend on meteorological circumstances that have a variable or stochastic component. This fact is often used by their detractors to favour the use of other alternatives such as fossil fuels. The main added value of the hybridisation concept will be the achievement of the Europe Strategic Energy Technology plan (SET-Plan), which is the market, the industry and the European Union goal on energy matters: self producing firm renewable energy with an optimal cost-efficiency ratio. A new hybrid CSP system, fully renewable will be developed at the pre-industrial scale by including a new configuration in a conventional CSP plant with storage system. This solution includes an aeroderivative gas turbine (AGT) exhaust gases simulator with a heat recovery system (HRS) that will recover the heat from the exhaust gases in the storage system. The evaluation of biomass derived gas fuels (bio-gas and syngas) production and consumption in the hybrid CSP plant will be studied, simulated and evaluated at a commercial scale. Moreover, both economic costs and technology of the new elements developed and adapted to the needs of this hybrid technology will be assessed from an operating profitability perspective and totally orientated to market feasibility. The project will involve six main research lines according to the major investigation areas: development of a new Heat Recovery System (designing specially carefully the materials and the thermal areas of each HRS component); development of an Integrated Operation and Control Systems and Tools (evaluating critical operations); improvements on production, upgrading, distribution and utilization of BDGF adapted to the needs of the hybrid technology; development of an AGT Exhaust gases simulator adapted to the needs of the hybrid technology; integration of the previous developments in the proposed HYSOL power plant and environmental and economic assessment.

Fight against climate change has its main battlefield at the energy sector. Electricity and transport are the largest contributors to GHG emissions; the trend in transport toward electric vehicle will increase pressure on the electricity system and fundamentally change its dynamics. With producers focused on their legitimate business targets, and consumers focused on security of supply and low prices, the burden of decarbonizing electricity falls on policy makers as driving force, and on transport system operators (TSOs) as technical managers that ensure the safety and stability of supply. Grid stability is a delicate equilibrium, where some agents provide stability via ancillary services (regulating voltage and frequency) and others rely on that stability (consuming energy and/or disturbing the frequency due to embedded capacitors/impedances); power producers are usually stabilizers (synchronous turbines that provide inertia against sudden changes). Penetration of non-synchronous renewables such as Wind and PV threatens to disrupt the balance, especially in islands and poorly interconnected areas, as they provide power but rely on stability provided by others; this forces the system to have lots of synchronous generators idle just for stability, which is inefficient and costly. GRIDSOL wants to change the approach: we propose Smart Renewable Hubs, where a core of synchronous generators (CSP and biogas combined cycle HYSOL) is integrated with PV under a dynamic control system (DOME), self-regulating and providing ancillary grid services thanks to firm, flexible generation on a single output, tailored to a specific location, relieving pressure on the TSO. The project will research an advanced control (DOME) to ensure operation efficiency and grid stability with higher RES penetration, and a multi-tower concept for CSP cost reduction and efficiency improvement, to provide secure, clean and efficient electricity by getting the most of each renewable primary source.

The overall goal of ECo is to develop and validate a highly efficient co-electrolysis process for conversion of excess renewable electricity into distributable and storable hydrocarbons via simultaneous electrolysis of steam and CO2 through SOEC (Solid Oxide Electrolysis Cells) thus moving the technology from technology readiness level (TRL) 3 to 5. In relation to the work program, ECo will specifically: Develop and prove improved solid oxide cells (SOEC) based on novel cell structure including electrode backbone structures and infiltration and design of electrolyte/electrode interfaces to achieve high performances and high efficiencies at ~100 oC lower operating temperatures than state-of-the-art in order to reduce thermally activated degradation processes, to improve integration with hydrocarbon production, and to reduce overall costs. Investigate durability under realistic co-electrolysis operating conditions that include dynamic electricity input from fluctuating sources with the aim to achieve degradation rates below 1%/1000 h at stack level under relevant operating conditions. Design a plant to integrate the co-electrolysis with fluctuating electricity input and catalytic processes for hydrocarbon production, with special emphasis on methanation (considering both external and internal) and perform selected validation tests under the thus needed operating conditions. Test a co-electrolysis system under realistic conditions for final validation of the obtained results at larger scale. Demonstrate economic viability for overall process efficiencies exceeding 60% using results obtained in the project for the case of storage media such as methane and compare to traditional technologies with the aim to identify critical performance parameters that have to be improved. Perform a life cycle assessment with CO2 from different sources (cement industry or biogas) and electricity from preferably renewable sources to prove the recycling potential of the concept

Auctions, as a competitive and market-based mechanism, are on the verge of becoming a prevailing feature in support policies for renewable energy in Europe. A comprehensive assessment of auctions and their suitability for renewable support in Europe is urgently needed to facilitate their successful design and cost-efficient implementation. Auctions have the potential to significantly improve the performance of renewable electricity support in Europe, but there are potential pitfalls and difficulties to be avoided. AURES combines dedicated, detailed and target-oriented analysis of auctions and their interactions with other energy policy mechanisms and markets with capacity building of policy makers and market participants. The project will identify and evaluate suitable auction design options and their effects under different market conditions using tailored theoretical, empirical, experimental, and model-based approaches, and so develop best practices and policy recommendations for future auction design. Building on worldwide experiences with auctions in energy policy and other industries and on close cooperation with ongoing auction implementation cases in Europe, a strong knowledge base will be developed, enabling policy makers and market participants to make informed decisions. This knowledge base will be processed in a flexible policy support tool that provides policy makers with tailor-made information suited to their specific situation and policy preferences. By facilitating an intense and continuous stakeholder dialogue and by establishing a knowledge sharing network via workshops, webinars, bilateral meetings, and expert consultations, the project will serve as capacity building platform. The project consortium consists of eight renowned public institutions and private firms representing seven European countries and includes some of the leading energy policy experts in Europe, with an impressive track record of successful research and coordination projects.

Most European offshore wind farms are currently installed within 20 km of the coast in shallow water depths up to 20m. The next generation will be developed at distances of 40 km in sea depths up to 80m. These new locations present technical challenges for engineering and the possibility of new synergies between all marine renewable energy resources including wave, tide and wind. Inspection and maintenance at depth is difficult and the raising of transmission voltages to keep cable sizes manageable is urgently required as the technical difficulty of hauling heavy cables is significantly increased. The availability of self-monitoring connectors to eliminate routine maintenance at greater depths is seen as a potential step-change improvement in infrastructure management and the development of ROV-installable wet-mate connectors as an alternative to dry-mated cable is a dominant industry objective. We will deliver a prototype 33kV hybrid wet-mate connector with a connectivity monitoring system and future-proof features for higher voltage connector technologies. This will lead to efficient power transmission, reduced installation and maintenance costs and precision remote monitoring that reduces routine maintenance and intervention by divers, benefitting health, safety and affordability.

The main goal of the BALANCE proposal is to gather leading research centres in Europe in the domain of Solid Oxide Electrolysis (SOE) and Solid Oxide Fuel Cells (SOFC) to collaborate and accelerate the development of European Reversible Solid Oxide Cell (ReSOC) technology. ReSOC is an electrochemical device that converts electrical energy into hydrogen (electrolysis mode) or alternatively fuel gas to electrical energy (fuel cell mode). It is characterised by its very high efficiency compared to competing technologies. ReSOC enables to store renewable electricity when it is produced in excess or to convert it into a CO2-free transport fuel. Therefore, it is considered as a key technology to allow the broad penetration of renewable electricity into the European energy system. Fragmented national research efforts are currently impeding quicker development and deployment of next-generation fuel cell and hydrogen technologies. Therefore, BALANCE will identify, quantify and analyse national activities dealing with the diverse aspects of ReSOC technology. This analysis will result in an integrated European research agenda for ReSOC technology to gain synergies and to generate breakthroughs in this highly promising but currently low-TRL technology. Close communication with the advisory board will enable alignment of the proposed agenda with the roadmaps and activities of EERA, IEC and IEA on the topic of hydrogen technologies. Technical development will cover the development of the next generation of ReSOC cells, their integration in the optimised stack assembly, and investigation of the constraints from reversible operation at system level and integration with the grid. Cost will be addressed by using low-cost materials and improving manufacturability. The experimental work will be supported by modelling and simulation at all scales and by the techno-economic analysis of different integration of the ReSOC technology in industrial applications.

TERRA project aims to develop, from TRL 3 to 5, a tandem electrocatalytic reactor (TER) coupling an oxidation reaction to a reduction reaction, with thus the great potential advantage of i) saving resources and energy (needed to produce the oxidant and reductants for the two separate reactions), and ii) intensify the process (reduce the nr. of steps, coupling two synthesis processes and especially eliminating those to prepare the oxidation and reduction agents). The proposal address one of SPIRE Roadmap Key Actions New ways of targeting energy input via electrochemical. The TER unit may be used in a large field of applications, but will be developed for a specific relevant case: the synthesis of PEF (PolyEthylene Furanoate), a next generation plastic. TERRA project aims to make a step forward in this process by coupling the FDCA and MEG synthesis in a single novel TER reactor, with relevant process intensification. Between the elements of innovation of the approach are: i) operation at higher T,P than conventional electrochemical devices for chemical manufacturing, ii) use of noble-metal-free electrocatalysts, iii) use of novel 3D-type electrodes to increase productivity, iv) use of electrode with modulation of activity, v) possibility to utilize external bias (from unused electrical renewable energy) to enhance flexibility of operations. In addition to scale-up reactor and test under environmental relevant conditions (TRL 5), the approach in TERRA project is to address the critical elements to pass from lab-scale experimentation to industrial prototype with intensified productivity. These developments are critical for a wider use of electrochemical manufacturing in chemical and process industries.

Numerous efforts have been done for achieving the maximum penetration of renewable energy sources (RESs) in the autonomous grids of Greek islands, which never exceeded 10%, despite the exceptional wind and solar potential. Large fluctuations on demand during summer, winter, and 24-h period in combination with the technical restrictions of diesel generators of the existing conventional power stations are a major concern of power supply system. Reversing the roles of diesel generators and wind farms (WFs), to use WF as the basic energy source and diesel generators as stand-by system changed in fact the whole philosophy of energy supply systems in islands and created perspectives for the fundamental reformation of the conventional energy supply systems in autonomous grids. In fact, methods of contemporary interim medium term energy storage are investigated for hybrid systems in order to adjust the stochastic behavior of wind energy to the demand, to provide the system with guaranteed power. This Wind-Hydro Plants in combination with the most adequate RES forming an Renewable Energy Supply System (RESS), increase further the economical penetration of RES into autonomous grids up to 90% or even 100% and simultaneously reduce drastically the fuel costs. Furthermore, a supergrid is examined and compared with RESS as another efficient way for achieving higher penetration of RES. © 2012 Elsevier Ltd. All rights reserved.
