Stable energy for an intelligent grid.
KaiLase Holding GmbH develops sodium-ion battery systems engineered for utility-scale storage, industrial energy resilience, and long-duration grid stabilization across the European market.
Why sodium-ion.
Abundant Materials
Sodium is among the most available elements on Earth. Our chemistry rests on materials that are abundant, regionally accessible, and free from the constraints of concentrated lithium supply chains.
Thermal Stability
A chemistry that tolerates wider operating temperatures and rejects thermal runaway. Sodium-ion cells are inherently safer, simplifying system design and reducing fire risk.
Sustainable Lifecycle
Recyclable, non-toxic, and manufactured with lower embodied energy. Sodium-ion aligns naturally with European ESG frameworks and circular-economy standards.
Where our systems operate.
Utility-Scale Grid Storage
Multi-hundred-megawatt-hour systems that absorb renewable surplus and release it when the grid needs it most.
Industrial Backup & Continuity
Long-duration resilience for factories, data processing sites, and critical facilities where downtime is not an option.
Renewable Integration & Load Balancing
Smoothing the intermittency of wind and solar, firming capacity, and stabilizing frequency across the European grid.
Datacenter Energy Resilience
Pairing high-density compute with dependable, long-duration storage — the natural connection between KaiLase's two divisions.
Complementary to the KaiLase datacenter divisionEngineered in Europe. Deployed at scale.
Cell Engineering
Electrode chemistry, cell format, and manufacturing process validated in European laboratories and pilot lines before industrial scale-up.
Module Assembly
Cells are assembled into standardized modules with integrated thermal management, monitoring, and safety systems.
System Integration
Modules are integrated into containerized and site-built systems with power conversion, control software, and grid-interconnection equipment.
Grid Deployment
Installation, commissioning, and grid certification, followed by long-term performance monitoring and maintenance programs.
