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.
