Recognising that current storage solutions are unable to stabilize enough the intermittent renewable energy production, new long term energy storage solutions are becoming mandatory. Current long-term energy storage is mainly provided by Pumped-Storage Hydroelectricity (PSH). Compressed Air Energy Storage (CAES) has appeared for decades as a credible alternative but its poor energy efficiency, the need of fossil fuels and the use of existing underground cavities as storage reservoirs have limited its development. Variations to CAES have shown low efficiency, losing a big percentage of energy as heat and mechanical losses. Since the 2010s, there is a strong revival of scientific and industrial interest on CAES, led by China and the European Union (EU). For the EU, leading the new generation of high-efficient, low climate-impact and long-term energy storage research, is key to increase its energy independency. In this context, the main objective of Air4NRG is the development of an innovative, efficient (over 70% RTE), long- term, and sustainable CAES prototype, which can enhance renewable energy availability and offers robustness and safety while increasing cost effectiveness and improving the environmental footprint. At the same time, it will promote innovation and competitiveness in the European energy storage industry, while prioritizing the principles of circular economy and environmental sustainability. Another key factor of the solution is the integrability to the electrical grid system and their intelligent EMS, which will be proven by the end of the project through end user integration activities (TRL5). The project will result in two prototypes: one of them will be a plug and play system fitting into a standard 40ft container with an over ten- hours storage duration, while the other will be a larger-scale system of 200kW with the same duration of storage. The developed system is a rare material-free solution with simple industrial infrastructure needs, allowing its full development within the EU, strengthening Europe’s position in the energy storage system sector.

The main project objective is to reduce the cost of energy (LCOE) of floating wind by 50% through the validation of the "PivotBuoy", an innovative subsystem that reduces the costs of mooring systems and floating platforms, allows faster and cheaper installation and a more reliable and sustainable operation. The PivotBuoy system combines the advantages of Single Point Mooring systems (SPM - pre-installation of the mooring and connection system using small vessels) with those of tension-leg systems (TLPs - weight reduction, reduced mooring length and enhanced stability), enabling a radical weight reduction of 50% to 90% in floating wind systems compared to current spar and semi-submersible systems but also enabling a critical simplification in the installation of traditional TLP systems. The PivotBuoy concept, initially conceived by its founder while at MIT, is currently at TRL3 after the proof of concept in a wave tank at 1:64 scale and it is the result of years of experience. The project proposes validating the concept at PLOCAN test site, integrating a part-scale prototype of the PivotBuoy single point mooring system in a 225kW downwind floating platform developed by X1 WIND. By testing in a relevant environment, the project will also validate critical innovations related to assembly, installation and O&M techniques, reaching TRL5 at the project end. The impact of the proposed innovations is sector wide: the system can be integrated not only in X1 WIND downwind platform but in any other floating platforms using single point moorings systems in the wind and in other sectors such as wave energy, tidal and oil&gas industries. The project consortium, combining experienced industrial partners from the oil&gas, naval and offshore wind sectors with cutting-edge R&D centres, will also bring additional innovations in components, materials and installation and O&M techniques, advancing the state-of-the-art of the floating wind sector.

Sustainable energy Positive & zero cARbon CommunitieS demonstrates and validates technically and socio-economically viable and replicable, innovative solutions for rolling out smart, integrated positive energy systems for the transition to a citizen centred zero carbon & resource efficient economy. SPARCS facilitates the participation of buildings to the energy market enabling new services and a virtual power plant concept, creating VirtualPositiveEnergy communities as energy democratic playground (positive energy districts can exchange energy with energy entities located outside the district). Seven cities will demonstrate 100+ actions turning buildings, blocks, and districts into energy prosumers. Impacts span economic growth, improved quality of life, and environmental benefits towards the EC policy framework for climate and energy, the SET plan and UN Sustainable Development goals. SPARCS co-creation brings together citizens, companies, research organizations, city planning and decision-making entities, transforming cities to carbon-free inclusive communities. Lighthouse cities Espoo (FI) and Leipzig (DE) implement large demonstrations. Fellow cities Reykjavik (IS), Maia (PT), Lviv (UA), Kifissia (EL) and Kladno (CZ) prepare replication with hands-on feasibility studies. SPARCs identifies bankable actions to accelerate market uptake, pioneers innovative, exploitable governance and business models boosting the transformation processes, joint procurement procedures and citizen engaging mechanisms in an overarching city planning instrument toward the bold City Vision 2050. SPARCS engages 30 partners from 8 EU Member States (FI, DE, PT, CY, EL, BE, CZ, IT) and 2 non-EU countries (UA, IS), representing key stakeholders within the value chain of urban challenges and smart, sustainable cities bringing together three distinct but also overlapping knowledge areas: (i) City Energy Systems, (ii) ICT and Interoperability, (iii) Business Innovation and Market Knowledge.

The main goal of the eNeuron project is to develop innovative tools for the optimal design and operation of local energy communities (LECs) integrating distributed energy resources and multiple energy carriers at different scales. This goal will be achieved, by having in mind all the potential benefits achievable for the different actors involved and by promoting the Energy Hub concept, as a conceptual model for controlling and managing multi-carrier and integrated energy systems in order to optimize their architecture and operation. In order to ensure both the short-term and the long-term sustainability of this new energy paradigm and thus support an effective implementation and deployment, economic and environmental aspects will be taken into account in the optimization tools through a multi-objective approach. eNeuron’s proposed tools enable tangible sustainability and energy security benefits for all the stakeholders in the LEC. Local prosumers (households, commercial and industrial actors) stand to benefit through the reduction of energy costs while leveraging local, low carbon energy. Developers and solution providers will find new opportunities for technologies as part of an integrated, replicable operational business model. Distribution system operators (DSOs) benefit from avoiding grid congestion and deferring network investments. Policy makers benefit from increasingly sustainable and secure energy supply systems. eNeuron is a high TRL project in line with the Work Programme, by developing innovative approaches and methodologies to optimally plan and operate integrated LECs through the optimal selection and use of multiple energy carriers and by considering both short- and long-run priorities. Through optimally coordinating all energy carriers and vectors, cost-effective and low-carbon solutions will be provided for fostering the deployment and implementation of this new energy paradigm at European level.
