With its “Clean Energy for all Europeans” package (CEP), the European Commission formally recognised and instrumentally brought forward community energy projects, including definitions for “Renewable Energy Communities” (RECs) and for “Citizen Energy Communities” (CECs). The new concepts introduced in the CEP set the course for a more active role of EU citizens in the energy markets. To fully concretize the benefits envisioned by the CEP, a myriad of barriers needs to be overcome and progress needs to be done to clarify and streamline the concepts of REC and CEC, enabling its uptake by all interested citizens. Motivated by that challenge, COMMUNITAS will promote energy citizenship, enabling citizens to take control of their own path towards sustainability by becoming an active element of the energy markets. The project will deliver a Knowledge Base that will provide users with technical, administrative, and legal information on ECs, streamlining the creation and expansion of this concept. COMMUNITAS will also deliver an innovative set of tools - capitalizing on technologies such as IoT, Blockchain and Cloud Computing - to unlock citizens’ active participation in energy markets and communities (all integrated into an open, digital “one-stop-shop” COMMUNITAS Core Platform (CCP)), allowing EC members to have an aggregated position in the energy markets or explore ancillary services using different energy assets or load profiles of the community. As a project that aims to position citizens in the centre of energy markets, COMMUNITAS has citizens at the centre of its own approach: citizens will be involved in Social and Policy Labs throughout the whole project, in order to frequently factor in their feedback, wishes, needs into the core developments of the project.

Efficient and effective use of offshore renewables is pivotal in the transition of the EU to become a net-zero economy in greenhouse gas emissions by 2050. EU-SCORES will unlock the large-scale potential of the roll-out of offshore renewable energy in multi-source parks across different European sea basins through two highly comprehensive and impactful demonstrations: (1) An offshore solar PV system in Belgium co-located with a bottom fixed windfarm and; (2) A wave energy array in Portugal co-located with a floating wind farm. The multi-source demonstrations in EU-SCORES will showcase the benefits of a continuous power output harnessing the complementarity between wind, sun and waves as it leads to a more resilient and stable power system, higher capacity factors and a lower total cost per MWh. These aspects will also improve the business case for the production of green hydrogen within these parks. The full-scale demonstrations will prove how the increased power output and capacity installed per km2 will reduce the amount of marine space needed, thereby leaving more space for aquaculture, fisheries, shipping routes and environmentally protected zones. Additional benefits attained by co-using critical electrical infrastructures and exploring advanced operation and maintenance methodologies supported by innovative autonomous systems will further lower the costs per MWh. The involvement of major project developers and utility companies (EDP, EGP, SBE, RWE, EnBW, Eneco, OceanWinds, and Parkwind) will ensure an accelerated path towards commercialisation of these innovative parks. Altogether, through a highly competent, skilled and motivated consortium EU-SCORES will pave the way for bankable multi-source parks including wind, wave and floating solar systems across different European sea basins by 2025, thereby supporting the stability and resilience of the European energy system, while considering sustainability, local stakeholders and existing ecosystems.

Transition to renewable energy sources (RES) is a critical step to slow down the climate changes, to overcome the energy crisis and to ensure energy independence between different regions of the world. Battery energy storage systems (BESS) are currently seen as important technological enablers for increasing the absorption of RES into the electric grid. However, improvements in their performance, cost competitiveness and sustainability should be achieved. For EU, the complete batteries value chain and life cycle has to be considered, from access to raw material, over innovative advanced materials to modelling, production, recycling, second life, life cycle and environmental assessments. LOLABAT’s 17 stakeholders aim to develop a new promising battery chemistry, RNZB (rechargeable NiZn Battery). The RNZB presented and developed during LOLABAT will have energy and power densities both the highest just after Li-ion batteries, cost the lowest just after the Lead-acid battery, while profiting from abundant and available raw materials, non-toxic elements, high safety, low risk of thermal runaway, limited environmental impact and high recycling potential. The ambitions (2024 and after) of LOLABAT are: further increase of the cycle life of NiZn (to at least 4000 cycles at 100% DoD be the end of project), development of NiZn for grid applications and its preparation for a production in Europe, by increasing its TRL via upscaling of capacity, design and integration of BMS and sensors built up in battery packs, testing and demonstration in stationary energy storage applications via six use cases in utility grid and industrial sites, its preparation for a future industrialisation by realisation of life cycle and life cycle cost analyses, recycling studies, assessment of norms, standards and grid compliancy, realisation of business model and market studies and finally an extensive dissemination and communication of the project results and NiZn technology.

ELEXIA will develop/upgrade validated tools for planning and managing integrated energy systems in different conditions and will integrate and combine energy systems across vectors and sectors towards a cost-optimised as well as flexible and resilient energy system of systems. A Digital Services Platform will host the energy management and planning services and will foster flexibility and sector coupling. A System Planning Toolbox will be developed and deployed to support effective sector coupling at local sites considering different scenarios, operational details, possibly conflicting interests of multiple local actors, and security of supply. An Energy Management Systems will be built and deployed for flexible, cost-optimised, and resilient operation of sector coupled local sites including forecasting, digital twins, optimization, control, monitoring, assessing operating conditions, predicting anomalous operation, and preventing occurrence of breakdowns. ELEXIA will demonstrate the use of planning and operational tools in a one-stop-shop, modular and open, digital platform at TRL7–8. It will demonstrate the benefits of sector integration at local / national level in three different geographical, climate and economic conditions in Europe: in an industrial port environment in Portugal, in an urban-city hub environment in Denmark, and in an industrial-urban-residential environment in Norway. ELEXIA will assess environmental, economic and social sustainability, will deliver a methodology for CAPEX / OPEX and value creation, and will focus on policy and governance. It will put focus on stakeholder engagement and societal acceptance and will ensure effort towards future exploitation and replication. ELEXIA will establish and demonstrate realistic and concrete pathways to ultimately achieve independence of fossil fuels by harnessing the latent flexibility of the energy system through integration, data-intelligence, and planning, working towards the 2050 European goals.

The wind energy sector continues growing rapidly even under the pandemic, as an estimated 93GW wind capacity was installed in 2020 globally. After installation, wind turbines are expected to run around 20-25years, during which O&M (operation and maintenance) becomes crucial in maximising the economic and environmental benefits of wind assets. This project aims to develop a complete solution for robotic based inspection and repair of wind turbine blades (WTBs), both onshore and offshore. Firstly, we will integrate thermography and shearography with laser heating, so that advanced lock-in techniques will be achieved for in-situ inspection of both surface and subsurface defects within WTBs. (Current techniques including drone-based are limited to surface defects only). Secondly, a compact and efficient robotic deployment system will be developed which will hold the inspection unit and a robotic repair arm. The robotic system will be operated by engineers working on ground (for onshore wind farms) or on a vessel (for offshore wind farms). When defects are detected and deemed reparable, the repair arm of the whole system will be activated to rapidly repair the faulty area of composite components by resistance welding for joining and/or disassembly. Comparing to the traditional adhesively bonding for repair, the proposed resistance welding with optimised processing would significantly reduce the curing cycles/time with much fewer preparation for surface treatment steps while it will be more easily designed to integrate with robotic arm. The whole system will be operated remotely by engineers working on ground or on a vessel without risking their lives working in the sky on WTBs. Field trials on wind towers will be conducted to validate the system.
