Wide scale implementation of renewable energy will require growth in production of inexpensive, efficient energy storage systems. The extension of battery technology to large-scale storage will become necessary as intermittent renewable energy sources such as wind, solar and wave become more prevalent and integrated into electrical grid. Lithium-ion battery appears as quite mature for this application but its cost per mWh remains high in comparison to high temperature technology such as Zebra, which integrate low cost sodium base materials. Furthermore, as the use of large format lithium battery becomes widespread; increase demand for lithium commodity chemicals combined with geographically constrained Li mineral reserves will drive up prices. Based on the wide availability and low cost of sodium, ambient temperature sodium-based batteries have the potential for meeting large scale grid energy storage needs. In NAIADES we will demonstrate the feasibility of ambient temperature Na-ion battery from the knowledge and achievement that has been done at the laboratory scale, up to a module demonstration in a realistic application environment. Several European industrials, institutes and universities belonging to ALISTORE-ERI have decided to join their efforts to assess the Na-ion technology for stationary storage application through building a 1 kW modules system Na-ion cell which will serve as data base to demonstrate economical and public acceptance. These module prototypes will be developed to meet performances in a 1kW system in a cost-effective, sustainable and environmental-friendly manner. New energy policy will be developed to integer the Na-ion battery in the Smart Grid initiative and promote the penetration of renewable energy in the electric network.

Intensified continuous processes are a key innovation of the last decade for the production of high quality, high value and customer-specific products at competitive prices in a sustainable fashion. To realize the potential of this technology, key steps must be made towards long-term stable, tightly controlled and fully automated production. The goal of the CONSENS project is to advance the continuous production of high-value products meeting high quality demands in flexible intensified continuous plants by introducing novel online sensing equipment and closed-loop control of the key product parameters. CONSENS will focus on flexible continuous plants but the results will be transferable also to large-scale continuous processes. The research and development is driven by industrial case studies from three different areas, spanning the complete value chain of chemical production: complex organic synthesis, speciality polymers, and formulation of complex liquids. Innovative PAT technology will be developed for online concentration measurements (mid-resolution process NMR), for the online non-invasive measurement of rheological properties of complex fluids, and for continuous measurements of fouling in tubular reactors. New model-based adaptive control schemes based on innovative PAT technology will be developed. The project results will be validated in industrial pilot plants for all three types of processes, including validation in production containers that have been developed in the F3 Factory project. Further, methods for sensor failure monitoring, control performance monitoring and engineering support for PAT-based solutions will be developed. The exploitation of the new technologies will be facilitated by a tool for technology evaluation and economic impact assessment. A Cross-sectorial Advisory Board supports the transfer of PAT technologies and adaptive control to neighboring sectors of the European processing industry.

Highly efficient organic electroluminescent devices (OLEDs) are a technology that promises to reduce significantly the electricity consumption. The estimated market for OLED lighting products is large ($8 billion) and European lighting manufacturers are ideally positioned to capture a large part of it. Glass OLED products prepared by vacuum evaporation techniques have been demonstrated with good performances, yet the main bottle neck for larger market introduction is the high cost. At high production volumes the cost of OLED production is directly related to the efficiency of materials usage which is estimated to be 70 % for vacuum deposition and 90 % via solution processing. Hence, roll-to-roll solution processed OLEDs, will lead to a significant price reduction due to more efficient organic material usage, lower capital investments and higher throughput. Additionally, these OLEDs will be produced directly on flexible substrates allowing for new light weight and space saving designs. SOLEDLIGHT will develop hybrid and fully S2S and R2R solution processed multilayer OLEDs with power efficiencies > 100 lm/W and lifetimes > 15000 hours at 3,000 cd/m2. This will be addressed by: New emitter and charge transport materials Methods to control multilayer stack formation. Interface and emitting layer morphology control. Implementing large-area roll-to-roll solution processing. Demonstration of flexible OLEDs integrated into a luminaire. SOLEDLIGHT will scale up both the chemical synthesis of these material systems and the R2R coating technology to a pilot production line. SOLEDLIGHT has assembled a consortium comprising a Osram (leading OLED manufacturer and integrator), Solvay (leading OLED materials manufacturer), TNO/Holst Centre (an excellence centre for organic devices with a state-of-the-art R2R line and leading universities in the field (Univ. Valencia, EPFL and Imperial College). The participation of Osram ensures a rapid transfer to future products.
