The Renewable Energy Directive (RED) sets a binding target for 42.5% of renewable energy in final energy consumption by 2030, requiring approximately 70% of Europe’s electricity to come from renewables. This drives a critical need for substantial energy storage to harness renewables effectively and ensure grid stability during periods of low generation. Energy storage captures and releases energy as needed, addressing the mismatch between supply and demand. Currently, storage capacity is far from meeting future needs, with only 9 GWh available in 2022 compared to the 108 TWh projected by 2040. Significant investment, estimated between €100-300 billion, is required to scale up storage infrastructure. Home storage systems and EV battery packs have immense potential to enhance grid stability and energy optimization in Europe, but their role remains untapped due to the lack of advanced technology for dual-purpose use and challenges in coordinating their dynamic and distributed nature. The ReVolta Suite combines the ReVolta Battery Manager and StoreNet platform, using AI and cloud computing to optimise battery performance. It ensures resilience, predicts energy demand, and extends battery lifespan through advanced algorithms and digital twin technology. Our solution increases battery lifespan by 42.5%, reduces downtime by 50%, and increases revenue from multi-purpose use. These advancements enable a 4-year ROI, making energy storage systems more viable for consumers and investors. To scale this innovation, we seek EIC blended finance to move our solution from TRL6 to TRL8. We will enhance key features like anomaly detection, root-cause analysis, and state-of-health estimation. Installation time will be reduced to just 15 minutes, and we will aim to cut battery downtime by 90%. We will integrate two new asset types - EV chargers and flexible loads, and achieve compatibility with at least five additional battery inverter brands. also

HiHELIOS aims to deliver a TRL 7 modular, scalable, circular-by-design and safe Hybrid Energy Storage System (HESS) that combines High-Power storage capabilities of LFP battery or supercapacitors, with High-Energy storage capabilities of second-life NMC batteries. To achieve this, HiHELIOS will adapt the modular, flexible and scalable HESS architecture developed in the EU project SEABAT to grid applications and EV charging support. HiHELIOS aims to design the HESS based on the shelf battery modules and components, and repurposing EV 2nd life battery modules. Supported by digital models, HiHELIOS will custom design and manufacture a HESS for 4 use-cases of problem owners to solve a real-life hybrid energy storage challenge. In HiHELIOS, the use-cases altogether cover storage services for supporting grid-connected microgrids and islanded grids; renewable energy uptake in weak and weak islanded grids; and EV charging, EV and E-boat fast-charging infrastructures, as well as ancillary services. The HiHELIOS HESS contains an innovative BMS and physics-based and data-driven PMS, EMS and cloud platform (based in the RED and Battery passport principles) enabling multiple (fast) services. HiHELIOS immediately achieves impact, because the 4 HiHELIOS demonstrators will stay in-use at the use-case owners after the project, until their end of life. HiHELIOS develops a roadmap to TRL 9 together with main stakeholders in the energy sector, and creates fertile soil for market application with replication studies. HiHELIOS will bring long durartion storage (>12 hours) within reach, against storage costs of less than €0.05/kWh/cycle by 2030, with a projected cycling life of >5,000 cycles. Via BRIDGE , ETIP-SNET and CEN-CENELEC , the experience emerging from HiHELIOS be used as input to national and EU-level standardization processes. HiHELIOS brings together a consortium of 12 partners from 6 countries, of which 4 partners are SMEs and 3 partners are from widening coutries.
