Investments in energy efficiency in the residential sector (27% of EU final energy demand) may also provide economic benefits at different levels of the economy. These benefits may not be realized because of barriers, which are typically reflected in implied discount rates. BRISKEE (Behavioural Response to Investment Risks in Energy Efficiency) provides evidence-based input to energy efficiency policy design and evaluation, thereby supporting the market uptake of energy efficiency technologies in the EU residential sector. It contributes to the work programme by addressing the interrelations between microeconomic factors, sectoral energy demand and macroeconomic effects, relying on a consistent methodological framework implemented in 5 work packages: • Provide empirical evidence for the magnitudes of discount rates accounting for differences across households, technologies and countries, and assess their effects on the diffusion of efficiency technologies in the EU (micro-level). A multi-country survey (1000 interviews per country) will be carried out and analyzed econometrically. • Explore the impact of time discounting and risk preferences (and of policies affecting those factors) on the diffusion of energy efficient technology and energy demand in the EU residential sector until 2030 (meso-level). Established bottom-up vintage stock models will be employed for appliances (FORECAST-Residential) and for buildings (Invert/EE-Lab). • Explore the macro-level impacts of changes in microeconomic decision-making and of energy efficiency policy on employment, GDP and exports in the EU until 2030. This involves simulations with an established macro-economic model for the EU (ASTRA). • Provide evidence-based recommendations for key energy efficiency policies and input for impact assessments and policy analysis at the three levels of analysis. • Communicate and disseminate empirical findings to policy makers, national experts, the research community and the general public.

The Integrated Roof Wind Energy System (IRWES) is the breakthrough solution overcoming all shortcomings of existing renewable energy solutions. IRWES is a roof-mounted, elegant structure with an internal – nonvisible – turbine making smart use of aerodynamics. It is more efficient than any existing urban windmill, and more efficient per area than PV panels when mounted on roofs higher than 20m. This novel system has highest efficiency based on IP protected and tested technology (TRL6). It reduces the payback time by effectively producing electric power in both high and low wind speeds resulting in both more efficiency and operational hours. The Netherlands counts 35.000 buildings suitable for application with attractive ROI, while greatest impact is achieved in Europe where 1/6 of the population lives in high-rise buildings. Customers have already committed to 25 units after demonstration. IRWES is a business opportunity ready for large growth, to serve the – until now – unreachable segment of local renewable energy supply to high buildings, while seamlessly aligning with the Horizon 2020 Work Programme objectives. Moreover, IRWES addresses European and global challenges such as reducing the risk of carbon “lock-in”, offering sustainable and affordable alternatives to rising electricity prices as well as closing the gap between R&D, innovation and entrepreneurship. Its market excellence is defined by meeting the important customer demands differentiating in aesthetical integration and customization; creating more value as an outstanding, attractive solution. Our business objectives have been outlined in 8 Work Packages to prepare the IRWES mass-market launch, positioning it as a game changing solution on the European market. Based on rigorous studies and feasibility assessments, already performed, we present a solid business plan that incorporates a commercialization strategy and a financing plan to underpin the foreseen market launch and growth strategy of IRWES.

URBAN LEARNING gathers capitals and other large cities across Europe facing the common challenge of considerable population growth while being committed to significantly reduce fossil energy consumption and CO2 emissions. E.g. Stockholm grew by more than 12.000 people / a (1.5%); in the next 10 years Vienna has to build for 200.000 new people. Efficient and effective planning processes will be crucial for climbing this mountain. Vienna, Berlin, Paris, Stockholm, Amsterdam/Zaanstad, Warsaw and Zagreb aim to enhance the capacity of their local authorities on integrative urban energy planning, as response to new challenges from EU EPBD and RES directives as well as to changes of technologies and market conditions and the pressure to provide sufficient, affordable homes. The focus is put on the governance processes related to the (re-)development of concrete sites. While some cities already started ambitious urban development projects, the institutionalisation of these experiences is missing - despite awareness and willingness, due to lack of knowledge, lack of time and the need for collaboration across departments, which is not a common practice in many administrations in Europe. External stimulus is needed to overcome these barriers, and to address these issues collectively with external key stakeholders, such as DNOs and energy suppliers, and across cities. Focus will be on multi-disciplinary learning – concentrating on innovative technological solutions, instruments and tools as well as on innovative governance elements - and to capitalise this learning to institutionalise integrative urban energy planning. Improving the governance processes is expected to have significant energy impacts on homes and workplaces to be built and refurbished for over 3 million more people in the participating cities in the next 20 years: more than 1.700 GWh/a of energy savings and over 2.000 GWh/a renewable energy produced. Special emphasis is put on knowledge transfer to 150 more cities.

In recent years, research has shown that energy savings resulting from energy efficiency improvements have wider benefits for the economy and society such as increases in employment, GDP, energy security, positive impacts on health, ecosystems and crops or resource consumption. In order to develop more cost-effective energy efficiency policies and optimised long-term strategies in the EU, these multiple benefits have to be accounted for more comprehensively in the future. Although this field of research is growing, the findings are disperse and mostly have important gaps regarding geographic, sectorial or technical measure coverage and findings vary largely. This makes a consideration of multiple benefits in policy making and policy evaluation difficult today. The proposed project addresses these issues and aims at closing the identified gaps by five central research innovations: 1) data gathering on energy savings and technology costs per EU country for the most relevant 20 to 30 energy efficiency measures in the residential, commercial, industrial and transport sectors, 2) developing adequate methodologies for benefit quantification, monetisation and aggregation, 3) quantifying the most important multiple benefits and where adequate, monetising, 4) developing an openly available calculation tool that greatly simplifies the evaluation of co-impacts for specific energy efficiency measures to enable decision-making and 5) developing a simple online visualisation tool for customisable graphical analysis and assessment of multiple benefits and data exportation. Project outcomes can thus directly be used by stakeholders and will help to define cost-effective policies and support policy-makers and evaluators in the development and monitoring of energy efficiency strategies and policies in the future.

Ampyx Power develops the PowerPlane, an Airborne Wind Energy System (AWES). AWES are second generation wind turbines that use the stronger and more constant wind at altitudes between 100 and 600 meters. Project AMPYXAP3 concerns the design, construction and testing of the first article of an initial commercial PowerPlane, version AP3. The global transition to a sustainable energy supply is burdened by the exorbitant societal costs associated with it. Renewable energy infrastructure projects have extremely high capital costs, and in most cases the cost per kWh of renewable electricity produced exceeds the cost of fossil-fuelled alternatives, thus requiring subsidies or other supportive instruments from governments. The economic effects of the energy transition are very significant, including the deterioration of international competitive position of countries or regions with high ambition levels regarding climate change, such as the EU – caused by rising electricity prices for industry. PowerPlane technology will have a disruptive effect on the electricity generation sector; due to the low levelised cost of energy (LCoE) that can be achieved with it, and due to its low capital costs. The need for a low cost, low capital investment renewable energy technology is evident. The AP3 PowerPlane, to be developed in the AMPYXAP3 project, fulfils the customer need of PowerPlane technology demonstration in long-term continuous safe operation at costs and LCoE as predicted. Ampyx Power aspires to manufacture and sell PowerPlane systems, as well as deliver operational and maintenance services to wind park owners. As a consequence, Ampyx Power projects revenues from PowerPlane system sales and installations, as well as from operation and maintenance (O&M) contracts. Hence, the AMPYXAP3 project is core business for Ampyx Power.

The offshore wind market is a young and rapidly growing market, whose current project pipeline for 2025/30 would equal nearly 80 nuclear plants, mostly in Europe. The next decade and beyond may average 1,000 offshore towers/year worldwide, with an overall investment volume around 15-20.000 M€/year. This growing sector faces technological challenges, as it is set to move into deeper waters further offshore while being able to reduce the costs in order to reach a competitive LCOE (levelised cost of energy). For water depths above 40m (70% of the future market) approximately 40-50% of investment corresponds to the substructure (foundation and tower). Therefore a significant cost reduction in foundation/tower would drastically improve the overall cost of offshore wind energy. This project intends to develop and demonstrate in operative environment a full scale prototype of a revolutionary substructure system for offshore wind turbines. The concept consists in a self-installing precast concrete telescopic tower which for the first time ever shall allow for crane-free offshore installation of foundations, towers and turbines, thus overcoming the constraints imposed by the dependence on offshore heavy-lift vessels. It will allow for a full in-shore preassembly of the complete system, which is key to generate a highly industrialized manufacturing process with high production rates and optimized risk control. The main benefits expected are: • 30-40% cost reduction (both CAPEX and OPEX). • Large water depth applicability range for deep offshore (>45m water depth). • Supports increased turbine size (5-8MW). • Allows for large scale fast industrial deployment of foundations. • Reduces dependence on costly and scarce installation vessels. • Improved asset integrity (durability) This solution will imply a radical step forward for cost-effective and industrially deployable deep offshore wind.

The project arises from a joint venture between Enair Energy SL and Lancor 2000 S Coop to develop a Cost efficient Small Wind Turbine (SWT) of 40 kW rated capacity (ECIWIND®).Within the wind energy sector, the small wind power is growing: According to World Wind Energy Association the small wind power market is expected to increase massively, from 768 M€ in 2013 to 2517 M€ by 2020, at a CAGR of 22%.The main challenge of the small wind energy industry is to decrease its costs to push a socialisation of this renewable technology. Thus, this electricity generation will be more competitive in the energy market and independent of the subsidies. The European Commision highliths the importance of Small and Medium Enterprises (SMEs) as small energy producers and the need to empower them to take up this role. Several european SMEs such as farms (200-400 kWh/day) and small industry (200- 450 kWh/day). In the case that these end users are located in areas where annual average wind velocity is higher than 5 m/s, small wind turbines in the 10-50 kW capacity is the best option to cover their energy needs. The acquisition and commissioning costs of SWT in this capacity range rounds 4000 €/kWh and have annual maintenance average costs of 1500 €/year depending on the configuration, which makes unaffordable the investment without government subsidies. The price reduction on this capacity range can be approached through the elimination of costly parts of current technologies as the Gearbox, and the optimization of the cost/performance of the rest of components.Enair and Lancor have therefore identified a business opportunity for SWT technologies and have developed a first prototype of ECIWIND® at 10 kW scale (free-gearbox with pitch control and permanent magnet generator SWT) that requires 50% less maintenance and decrease the price to end user installed in 40%, which entails an investment payback period <6 years without any government subsidy.

HoNESt (History of Nuclear Energy and Society) involves an interdisciplinary team with many experienced researchers and 24 high profile research institutions. HoNESt’s goal is to conduct a three-year interdisciplinary analysis of the experience of nuclear developments and its relationship to contemporary society with the aim of improving the understanding of the dynamics over the last 60 years. HoNESt’s results will assist the current debate on future energy sources and the transition to affordable, secure, and clean energy production. Civil society's interaction with nuclear developments changes over time, and it is locally, nationally and transnationally specific. HoNESt will embrace the complexity of political, technological and economic challenges; safety; risk perception and communication, public engagement, media framing, social movements, etc. Research on these interactions has thus far been mostly fragmented. We will develop a pioneering integrated interdisciplinary approach, which is conceptually informed by Large Technological Systems (LTS) and Integrated Socio-technical System (IST), based on a close and innovative collaboration of historians and social scientists in this field. HoNESt will first collect extensive historical data from over 20 countries. These data will be jointly analyzed by historians and social scientists, through the lens of an innovative integrated approach, in order to improve our understanding of the mechanisms underlying decision making and associated citizen engagement with nuclear power. Through an innovative application of backcasting techniques, HoNESt will bring novel content to the debate on nuclear sustainable engagement futures. Looking backwards to the present, HoNESt will strategize and plan how these suitable engagement futures could be achieved. HoNESt will engage key stakeholders from industry, policy makers and civil society in a structured dialogue to insert the results into the public debate on nuclear energy.

The main objective of Riblet4Wind is the transfer of a technology that has already demonstrated its capacity for increasing the energy efficiency in the aeronautics sector, to the wind energy industry. Application of functional coatings with riblet structure will improve the drag to lift ratio of rotor blades significantly. Wind tunnel experiments have proven the capability of this riblet-coating technology to increase the efficiency of wind turbines by up to 6%. This direct effect will allow gaining the same amount of electrical energy with smaller rotor blades. Indirect effects will increase the benefit to approximately more than 10%: • The improved drag to lift ratio will allow operation at lower wind speeds. The earlier cut-in of the WTG will improve the facility to balance in the electrical grid system. • The riblet structure improves the stall and turbulence behaviour of the rotor blades thus allowing also operation at higher wind speeds and/or operation in less optimum wind conditions, e.g. changing wind directions or gusts. • The improved drag to lift ratio will reveal design options due to changes of the design loads. • The riblet structure will also result in a substantial reduction of noise emissions. It is expected that the interaction of direct and indirect effects will contribute significantly to the targets of the European Wind Energy Technology Platform (TPWind) as declared in the new Strategic Research Agenda / Market Deployment Strategy (SRA / MDS) : a reduction of levelised costs of energy (LCoE) by 20% (onshore) respectively 50% (offshore) until 2028 (LCoE reference 2008). Beyond the focus of the topic H2020-LCE3-2014 the riblet-paint technology can also be applied on existing rotor blades, thus supporting retrofitting of existing wind turbines and maximising the benefit. In total Riblet4Wind aims at demonstrating the successful transfer of the riblet-coating technology and the semi-quantitative assessment of the direct and indirect effects.

EcoSwing aims at world's first demonstration of a superconducting low-cost, lightweight drive train on a modern 3.6 MW wind turbine. EcoSwing is quantifiable: The generator weight is reduced by 40% compared to commercial permanent magnet direct-drive generators (PMDD). For the nacelle this means a very significant weight reduction of 25%. Assuming series production, cost reduction for the generator can be 40% compared to PMDD. Finally, reliance on rare earth metals is down by at least two orders of magnitude. This demonstration is enabled by the increasing maturity of industrial superconductivity. In an ambitious step beyond present activities, EcoSwing will advance the TRL from 4-5 to 6-7. We are shifting paradigms: Previously, HTS was considered for very big, highly efficient turbines for future markets only. By means of cost-optimization, EcoSwing targets a turbine of great relevance already to the present large-scale wind power market. The design principles of EcoSwing are applicable to markets with a wide range of turbine ratings from 2 MW to 10 MW and beyond. Despite technological successes in superconductivity, turbine manufacturers and generator suppliers are hesitant to apply HTS into the wind sector, because of real and perceived risks. The environment inside a wind turbine has unique requirements to generators (parasitic loads and moments, vibration, amount of independent hours of operation). Therefore, a demonstration is required. The consortium represents a full value chain from materials, over components, up to a turbine manufacturer as an end-user providing market pull. It features competent partners on the engineering, the cryogenic, and the power conversion side. Also ground-based testing before turbine deployment, pre-certification activities, and training are included. EcoSwing can become tangible: The EcoSwing demonstrator will commence operation in 2018 on an existing very modern 3.6 MW wind turbine in Thyborøn, Denmark.
