HiTHIUM, a leading global energy storage manufacturer, has unveiled its latest breakthrough product—the ∞Power Flexso—at a launch event in Milan, Italy. This new battery energy storage system (BESS) is housed in a standardized 10-foot container and specifically engineered to overcome transportation and regulatory barriers in weight-sensitive regions, enabling faster, safer, and more cost-effective project deployment worldwide.

Large-scale BESS projects frequently encounter logistical challenges in areas with strict road transport regulations, particularly for hazardous materials under ADR Class 9. The ∞Power Flexso directly tackles these issues with a transport-optimized design that reduces logistical complexity while delivering exceptional energy density and safety. Its compact 10-foot format complies with regional transport requirements without the need for special permits or extensive disassembly.

“The ∞Power Flexso isn't just a new product—it's a holistic solution for developers and asset owners dealing with complex transport and regulatory landscapes,” said Luca Tonini, Senior Director of Global R&D and Product at HiTHIUM. “Through modular design and factory pre-assembly, we are reducing project risks and enabling scalable global deployments.”

Key Benefits of the ∞Power Flexso:

- Transport-Optimized 10-Foot Design: Weighing under 26 tons per unit, it aligns with standard road freight limits (≤44t without special permits), avoids costly disassembly, and streamlines logistics.

- High Areal Energy Density: Achieving approximately 423 kWh/m², it ranks among the highest-density BESS solutions worldwide, optimizing capacity with minimal land use.

- Comprehensive Safety Protections: Multi-level safety mechanisms from cell to system level, including thermal runaway prevention, aerosol suppression, and compliance with UL1973 and IEC 62619.

- Faster Deployment: Pre-assembled modules cut installation time and on-site labor, reducing the total cost of ownership.

- ESG-Focused Design: Features recyclable materials, low global warming potential (GWP) refrigerant R32, and noise levels below 65 dBA.

Designed for Worldwide Deployment

Although introduced in Italy within the MACSE (Meccanismo di Approvvigionamento di Capacità di Stoccaggio Elettrico) framework, the ∞Power Flexso is designed for diverse international markets—including Europe, Latin America, and Asia—where transport rules, space constraints, or hazardous material handling present obstacles.

The system also enhances project bankability through HiTHIUM’s customized financing and end-to-end service support, helping developers and operators streamline processes from permitting to operation. Initial deliveries of the ∞Power Flexso are planned for Q2 2026 in key target markets.
