With 37% of the overall consumption of electrical energy, industrial production is one of the most energy-intensive sectors in Europe. A major driver of both, energy consumption and energy costs are machine tools used the processing of materials, esp. in the automotive, mechanical engineering and aerospace segments. These machine tools are not only consuming huge amounts of energy, they also cause frequent power peaks, thus requiring very high connected loads. These peak loads have a negative effect on the European power grid stability, therefore, the provision of such high connected loads is very expensive. As pioneer in the electrification of forming machine tools, EBM has developed Enerstor – an electric energy power storage levelling module. This modular energy storage solution can be directly connected to any kind of machine tool, thus significantly reducing energy consumption of the machine tool and entirely levelling power peaks. This solution directly addresses current user needs of the European industry, including reduced energy costs through lower consumption and connected loads, higher flexibility in production, less emissions, and decreased investment costs. It helps the European industry and especially the segment for machine tools to stay competitive. With over 1,400 companies in Europe, the machine tools industry currently worth 25 bn € is very important for Europe in terms of employment and wealth. Innovative solutions are therefore crucial to further extend the industry’s position in the global market. In the feasibility study, a detailed analysis of the best-fitting market segments within the machine tools market will be conducted, including the involvement of pilot customers for the validation of the business idea, as well as the elaboration of a thorough business plan for commercialisation. The findings of the feasibility study will be integrated into the subsequent SME Phase 2 project to perfectly facilitate the market introduction of Enerstor.

There is enough waste energy produced in the EU to heat the EU’s entire building stock; however despite of this huge potential, only a restricted number of small scale examples of urban waste heat recovery are present across the EU. The objective of REUSEHEAT is to demonstrate, at TRL8 first of their kind advanced, modular and replicable systems enabling the recovery and reuse of waste heat available at the urban level. REUSEHEAT explicitly builds on previous knowledge and EU funded projects (notably CELSIUS, Stratego and HRE4) and intends to overcome both technical and non technical barriers towards the unlocking of urban waste heat recovery investments across Europe. Four large scale demonstrators will be deployed, monitored and evaluated during the project, showing the technical feasibility and economic viability of waste heat recovery and reuse from data centres (Brunswick), sewage collectors (Nice), cooling system of a hospital (Madrid) and underground station (Berlin). The knowledge generated from the demonstrators and from other examples across the EU will be consolidated into a handbook which will provide future investors with new insight in terms of urban waste heat recovery potential across the EU. Innovative and efficient technologies and solutions, suitable business models and contractual arrangements, estimation of investment risk, bankability and impact of urban waste heat recovery investments, authorization procedures are examples of handbook content. The handbook will be promoted through a powerful dissemination and training strategy in order to encourage a rapid and widespread replication of the demonstrated solutions across the EU.

The MOST project aims to develop and demonstrate a zero-emission solar energy storage system based on benign, all-renewable materials. The MOST system is based on a molecular system that can capture solar energy at room temperature and store the energy for very long periods of time without remarkable energy losses. This corresponds to a closed cycle of energy capture, storage and release. The MOST project will develop the molecular systems as well as associated catalysts and devices to beyond state-of-the-art performance and scale. Further, the MOST systems will be combined with thermal energy storage (TES) in a hybrid concept to enable efficient and on-demand utilization of solar energy. The hybrid structure of the device, combining TES and MOST, enables the operation of the system in two different modes, targeting different applications. In mode A, the objective is to reach a stable thermal output. In this operation mode, the MOST system is used to mitigate the daily variation in solar flux which consequently leads to a variable output of the TES. In operation mode B, the system is targeting larger temperature gradients under shorter durations of time. Mode A is simulating applications where a stable temperature output is needed, such as e.g. heat to power generation. Mode B is simulating operation where the system operates as a part of a larger energy system where the task is to mitigate variations in energy demand and energy production. The materials production features scalable, green chemistry production routes. Further, the project will build an innovation ecosystem around the project and engage with future users of the technology in order to ensure future development and EU capacity for future market implementation.

STARCELL proposes the substitution of CRM’s in thin film PV by the development and demonstration of a cost effective solution based on kesterite CZTS (Cu2ZnSn(S,Se)4) materials. Kesterites are only formed by elements abundant in the earth crust with low toxicity offering a secure supply chain and minimizing recycling costs and risks, and are compatible with massive sustainable deployment of electricity production at TeraWatt levels. Optimisation of the kesterite bulk properties together with redesign and optimization of the device interfaces and the cell architecture will be developed for the achievement of a challenging increase in the device efficiency up to 18% at cell level and targeting 16% efficiency at mini-module level, in line with the efficiency targets established at the SET Plan for 2020. These efficiencies will allow initiating the transfer of kesterite based processes to pre-industrial stages. These innovations will give to STARCELL the opportunity to demonstrate CRM free thin film PV devices with manufacturing costs ≤ 0.30 €/Wp, making first detailed studies on the stability and durability of the kesterite devices under accelerated test analysis conditions and developing suitable recycling processes for efficient re-use of material waste. The project will join for the first time the 3 leading research teams that have achieved the highest efficiencies for kesterite in Europe (EMPA, IMRA and IREC) together with the group of the world record holder David Mitzi (Duke University) and NREL (a reference research centre in renewable energies worldwide) in USA, and AIST (the most renewed Japanese research centre in Energy and Environment) in Japan. These groups have during the last years specialised in different aspects of the solar cell optimisation and build the forefront of kesterite research. The synergies of their joined efforts will allow raising the efficiency of kesterite solar cells and mini-modules to values never attained for this technology.

The proposed Action will support analytical work carried out in the context of the IEA-Morocco Joint Work Programme (JWP). Under the JWP, which came into effect on 28 June 2017, the IEA will provide technical support and advice to assist Morocco in developing a strategy to design an integrated assessment of long-term low carbon energy transition pathways. The IEA-Morocco work programme will include capacity building and training in data and statistics; modelling and support for the de-carbonisation programme. The IEA will also provide advice on further energy price liberalisation and energy security in the oil, gas and electricity sectors. It will also advise the Moroccan Ministry of Energy, Mines and Sustainable Development (MEMDD) and related stakeholders on optimal technologies and best practices that can be implemented to help Morocco attain its Energy Efficiency and Renewable Energy targets. It is anticipated that EU support will cover the Energy Efficiency and Renewable Energy work streams outlined in the JWP. In addition to on-site visits, IEA experts will host interactive webinars in English with Moroccan energy efficiency stakeholders on mutually agreed priority areas. The IEA could also assist MEMDD and the Moroccan Agency for Energy Efficiency (AMEE) in assessing the economic and other conditions for a push towards clean, electric cooking. The main purpose of this activity would be to ensure that energy efficiency measures are accelerated and run parallel with renewable energy deployment. This proposal relates to item 57 in the Horizon 2020 Work Programme for 2016-2017. This action will be instrumental in supporting Morocco’s transition to a reliable, sustainable and competitive energy system, in particular in Horizon 2020 priority areas such as reduction in energy consumption and carbon footprint; generation and transmission of lower-cost, low-carbon electricity; new knowledge and technologies;

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.

Energy storage technologies have long been a subject of great interest to both academia and industry. The aim of this project is to develop a novel, cost effective and high performance Latent Heat Thermal Energy Storage System (LHTESS) for seasonal accumulation of solar energy in increased quantities. The major barrier for currently used Phase Change Materials (PCMs, organic and hydrated salts) is their very low heat conduction coefficient, low density, chemical instability and tendency to sub-cooling. Such inferior thermo-physical properties result in the LHTESS having large dimensions and not having a capacity to provide the necessary rate of heat re-charge and discharge, even with highly developed heat exchangers. The new approach to overcome the above issues is the deployment of low grade, eutectic low melting temperature metallic alloys (ELMTAs). The ELMTAs are currently produced for application in other areas and have not been actively considered for the thermal energy accumulation with the exception of very limited studies. Their heat conduction is two orders of magnitude greater than that of conventional PCMs, they are stable and provide the thermal storage capacity which is 2-3 times greater per unit of volume. The project consists of both theoretical and experimental investigations. A range of low grade ELMTAs for application in LHTESS will be selected and Differential Scanning Calorimetry will be used to measure their thermal properties. Thermal cycling tests of such alloys will be conducted. Numerical investigations of heat transfer and flow in the LHTESS with ELMTAs will be performed. Experimental studies of heat transfer and flow in a laboratory prototype of the LHTESS with ELMTAs will be conducted. As outcomes of investigations, dimensionless heat transfer correlations will be derived and design recommendations for a practical solar energy seasonal LHTESS with the low grade ELMTA will be produced for project industrial partner

The aim is to develop and install a pre-commercial wave energy converter (WEC) of 1MW power, the WAVESTAR C6-1000 device, with main targets the device industrialization and the demonstration of wind and wave energy applications. The utility company Parkwind, which develops, builds and operates wind farms in the North Sea, is committed to the achievement of WAVESTAR’s next development stage. Parkwind provides the installation site with grid connection for the first full-scale WAVESTAR WEC, located within a Belgian offshore wind farm. The UPWAVE project consortium has been developed through the establishment of strong synergies and partnerships, by bringing together key European industrial players and European universities represented by wave energy experts whose overall objectives focus on: 1) Reduction of the device’s cost by introducing new design, components and materials. Cost optimization is achieved through new methods on deployment, installation, operation and maintenance. 2) Improvement of the energy efficiency by developing a more advanced Power Take Off based on a second generation digital hydraulic system and innovative control strategy. 3) Integration of wave energy converters in wind farms by considering the interaction between wave and wind devices in terms of operation, cost reduction and maximization of environmental benefits. Public research programs, industrial cooperation and technology transfer from the offshore industry (offshore wind, oil and gas) ensure the development of manufacturing processes, automation and optimisation of the WAVESTAR C6-1000 WEC. New certificates and standards will be made available for the wave energy industry. After the completion of the UPWAVE project, the cost of wave energy will be significantly reduced to a level in line with the cost of offshore wind energy (around 15 c€/kWh). The WAVESTAR C6-1000 demonstrator device will lead to a commercial WEC and a hybrid renewable energy device (wind and wave).
