demonstrating a High-energy and High-power hybrid battery storagE soLutIonS platform for multiple grid services

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.
