Storage is becoming one of the most critical assets for modern energy systems. At the same time storage is a very diverse universe of solutions and technologies with very different characteristics. InterSTORE plans to address this complexity by developing an innovative middleware that, while virtualising the storage technology, will simplify its use from the point of view of integration platform thanks to a technology agnostic approach.The middleware will facilitate the integration of storage creating an independence from hardware solutions which are critical from customer perspectives to avoid vendor lock-in solutions. It will also facilitate its use from a monetisation perspective making sure that more investments in storage are enabled. InterSTORE middleware will be released as a full open-source product integrating a set of already available standards and protocols in a coherent and advanced architecture.The new InterSTORE solution will be tested and validated in a laboratory environment with the goal to develop testing software to be adopted in the future for interoperability certification. The middleware solution will also be integrated both in open source and commercial platforms that will be integrated in 4 real life demos to enhance the flexibility platforms and analyze the user acceptance and economic value of the new solution. Moreover, new and legacy systems will be taken into account. InterSTORE also has a strong focus towards impact. The solution will become part of existing commercial platforms ensuring that a real adoption will be deployed beyond the end of the project. The consortium will ensure that software maintenance will continue beyond the end of the project with the support of Linux Foundation Energy and that the work done will be considered by on-going standardization activities. SSH experts will perform an impact analysis to maximize the economic impact adopting innovative approaches to data monetization in the context of data spaces.

Sodium-ion batteries offer enhanced cost-effectiveness and sustainability, challenging the dominance of lithium batteries in the stationary energy storage sector. The SPRINT project will gather 8 industries, 2 SMEs and 8 academic partners (incl. one associated partner) for 46 months to optimise and demonstrate two sustainable, techno-economically viable and safe quasi-solid-state sodium-ion batteries better meeting the requirements of stationary energy storage applications. This will be achieved relying on abundant, non-toxic, safe, and competitive materials available in EU supply chains brought to scale within SPRINT, i.e. optimised NFP cathode materials relying on novel synthesis; hard-carbon materials derived from a validated forest residues supply chain in Northern Europe; and quasi-solid-state polymer and polymer composite electrolytes with a solvent-free synthesis, and which are major advancements vs. flammable liquid electrolytes. Strategic interface optimisations will be leveraged to meet end-users’ requirements in terms of cells’ cycle life. SPRINT also aims to bring to scale dry electrode processing (incl. using PFAS-free binders) to enhance the sustainability of battery manufacturing. Batteries encompassing such solutions will be demonstrated on two demonstration sites in Austria (portfolio hybridisation, balancing services) and Lithuania (residential PV, increased grid capacity for EV chargers), and SPRINT will also engage with international use-case providers (e.g. Morrocco, Tunisia, Kenya, Sierra Leone, etc.). All in all, it is foreseen that SPRINT will reduce costs (0.04€/kWh/cycle), enhance energy density (>200Wh/kg & >420Wh/L) and power metrics (>500 W/kg), improve cells' cycle life (projected >5,000 cycles), while ensuring safe operation (leak-free technology) for a high market penetration. The Consortium will accompany all solutions to commercialisation, supported by the created Exploitation Board to facilitate their uptake.

The ambition of the STREAM project (STREAM) is the creation of an innovative and robust flexibility eSTREAM project aims to create an innovative and robust flexibility ecosystem (“STREAM Ecosystem”) on the low voltage (LV) grid side of existing power markets connecting data, technologies, stakeholders and markets, thus facilitating the flexibility provision. A variety of benefits for both technical- and non-technical aspects of energy services supporting power market and power grid operations will be created. STREAM will empower data from flexible devices and support creation of other citizen services through a User-centric Approach to improve their acceptance. The exploitation of both types of services will benefit from new business models, built upon local LV flexibility markets and novel barter-like mechanism, developed in STREAM. Presently, such services and business models don’t exist in either established- or developing power markets. The STREAM ecosystem covers their implementation, includes various stakeholder groups on all levels of power markets, from small-scale end-users, energy communities, ESCOs, service providers, to market- and system operators. To achieve the goals, STREAM consortium comprises relevant actors to capture the entire flexibility value chain within STREAM ecosystem from end users, energy communities to service providers, flexibility services providers, market operators, DSOs, and TSO, complemented by technology and research partners. The latter will supply knowledge in a form of STREAM tools that will enable the realization of STREAM ecosystem. They will be adapted, deployed, calibrated, and demonstrated in the 4 STREAM pilots that serve as a basis for benchmarking of STREAM ideas. They cover geographical, economic, size and type diversity of the consumers. While complementary, the pilots focus on a specific part of STREAM Ecosystem. The pilot partners have all the essential roles and authority to carry out the specified activities.

SENERGY NETS aims at demonstrating the technical and economic capability of multi-energy systems to decarbonize the heating and cooling, power and gas sectors through renewable energy sources produced locally as well as sector integration, by primarily focusing on promising infrastructure and business models. To do so, SENERGY-NETS will develop a set of tools and platforms (up to TRL7/8) aimed to optimise the planning of District Heating and Cooling as well as distribution grids with sector coupling consideration and allow the provision of flexibility services to Distribution and Transmission System Operators. These solutions will be implemented on three pilot sites located in Milan (IT), Ljubljana (SI) and Paris (FR) and their replicability will be tested in two additional real case studies presenting alternative climatic, economic and geographic conditions in Västerås (SW) and Cordoba (ES). The SENERGY NETS solutions will be adapted to the main stakeholders at the different phases of the projects development involving sector coupling: long term planning, design and simulation, operational planning, valorisation, evaluation and replication. The project will evaluate the benefits through a consolidated methodology developed to estimate the overall value created by sector integration, relying on the current economic, regulation and market rules and assess the impacts on the European power system. SENERGY NETS relies on a strong trans-disciplinary consortium involving 17 organisations located in 7 European countries, involving renowned experts from public authorities, infrastructure providers, research institutions, entrepreneurs and consumers associations. Altogether, they will provide the necessary knowledge, expertise and capacities to develop, demonstrate and evaluate developed tools and services enabling the integration of multi-energy systems to provide flexibility to the power system, and ultimately enable the decarbonisation of the energy system.

Aiming at decarbonising the energy systems of geographical islands, MAESHA will deploy the necessary flexibility, storage and energy management solutions for a large penetration of Renewable Energies. Cutting-edge technical systems will be developed and installed, supported by efficient modelling tools and adapted local markets and business frameworks. A community-based approach will be adopted to ensure the constant consideration of local populations’ best interests throughout the project. Putting together 10 SMEs, 3 industrial partners, 2 universities and 6 public organisations from 9 countries, MAESHA gathers strong partners with the needed expertise to develop and disseminate relevant solutions for a universally beneficial energy transition on islands. After establishing the proper use-cases and architecture designs to ensure interoperability (WP1), MAESHA will develop modelling tools from real-time to long-term energy-economy observations (WP2) together with adapted business, market and regulatory frameworks (WP4). In parallel the community-based approach will be launched (WP3). All these activities lay the foundation for the technical development of management systems for aggregating flexibility (WP5) and devices based on synergies with assets of the territories (WP6), optimised together through a flexibility aggregating platform (WP7). After systems integration (WP8), the solutions will be fully demonstrated on Mayotte (WP10) and their replicabilities will be studied in five follower islands (WP10). Dedicated WPs for communication, dissemination (WP11) and management (WP12) will maximize the impacts. With its activities, MAESHA is expected to lead to at least 70% RE penetration and reach more than 90% of Mayotte’s population. Through its strong local implantation and the focus put on replication and dissemination activities, MAESHA will deeply modify insular energy features throughout Europe and its impacts will be felt far beyond the project’s framework.
