THE PROBLEM
Europe's rising electricity demand and increased renewable energy generation are straining the grid, leading to energy curtailment in regions with high shares of renewables. Long-duration energy storage systems (ESS) are essential to balance supply and demand and prevent this curtailment.
However, current battery technologies either offer high-power or high-energy storage, but not both, limiting their effectiveness. To meet EU goals and support grid stability, Europe urgently needs a versatile solution that can efficiently address both power and energy storage demands.
THE PROJECT
HiHELIOS is developing an advanced Hybrid Energy Storage System (HESS) that combines high-power and high-energy storage solutions using Lithium Iron Phosphate (LFP) and second-life Nickel Manganese Cobalt (NMC) batteries. The project will adapt technology from previous marine applications to support grid stability, renewable energy integration, and EV charging.
The project aims to deliver cost-effective, long-lasting energy storage by customizing solutions for four real-world use cases. The project will impact national and EU standards and ensure long-term benefits.
The main objectives of the HiHELIOS project are the following:
Develop a modular, flexible and scalable system architecture for hybrid battery topologies for stationary applications compatible with 1st and 2nd life battery types
Develop a digital simulation framework for optimal hybrid battery system design and sizing for various grid applications
Develop an interoperable, scalable, robust, multi-layered and cyber-secured control system
Optimise physics-based and data-driven multi-chemistry models for real-time State of Health (SOH) diagnosis
Engineer and manufacture Hybrid Energy Storage Systems (HESS), demonstrated in four real-life use cases
Conduct socio-techno-economic analysis and Life Cycle Assessments (LCA), develop business cases, and create a commercial roadmap for market readiness
