HiTHIUM, a leading global energy storage manufacturer, today unveiled its latest innovation at the ∞Power Flexsso product launch event in Milan, Italy. The new battery energy storage system (BESS) is built within a standardized 10-foot container and specifically engineered to overcome transportation and regulatory challenges in weight-restricted regions—unlocking faster, safer, and more cost-effective project deployment worldwide.
Large-scale BESS installations often face hurdles in regions with strict road transport regulations, particularly for hazardous materials classified under ADR Class 9. The ∞Power Flexsso directly addresses these challenges with a transport-optimized architecture that minimizes logistical complexity while maximizing energy density and safety. Its compact 10-foot design enables local transport compliance in multiple regions without the need for special permits or extensive disassembly.
“The ∞Power Flexsso is more than a new product—it’s a complete solution for developers and asset owners navigating complex transport and regulatory requirements,” said Luca Tonini, Senior Director of Global R&D and Product at HiTHIUM. “By combining modular design with factory pre-assembly, we’re reducing project risk and enabling truly scalable deployments in markets worldwide.”
Key Advantages of the ∞Power Flexsso
Transport-Optimized 10-Foot Design: Each unit weighs under 26 tons, aligning with common road freight standards (≤44t without special permits), eliminating costly disassembly, and simplifying logistics.
High Areal Energy Density: Delivering ~423 kWh/m², the system is among the highest-density BESS offerings globally, maximizing capacity while minimizing land use.
Comprehensive Safety Architecture: Built-in multi-layer protections from cell to system level, including thermal runaway prevention, aerosol suppression, and compliance with UL1973 and IEC 62619 standards.
Rapid Deployment: Factory-preassembled modules reduce installation time and on-site labor, lowering the total cost of ownership.
Sustainability & ESG Focus: Incorporates recyclable materials, low-GWP refrigerant R32, and maintains noise levels under 65 dBA.
Designed for Global Applications
While showcased in Italy under the framework of MACSE (Meccanismo di Approvvigionamento di Capacità di Stoccaggio Elettrico), the ∞Power Flexsso is designed for deployment across diverse global markets—from Europe to Latin America and Asia—where transport regulations, limited space, or hazardous material handling pose deployment challenges.
The system also strengthens project bankability with HiTHIUM’s tailored financing options and end-to-end service support, helping developers and operators streamline execution from permitting through to operation. ∞Power Flexsso will begin its first deliveries planned for Q2 2026 to the key markets.
