Lithium-ion energy storage system BlueVault™

containerized

Overview
BlueVault™ is a containerized lithium‑ion energy storage system designed for marine, offshore and diesel‑electric power plant applications. It supports all-electric and hybrid configurations and can be integrated into newbuild installations or retrofitted into existing diesel‑electric plants. Siemens Energy teams tailor the system to maximize battery life, performance and safety while aiming for a low‑emission platform.

Key benefits

• Provide on‑demand, dispatchable renewable power
• Increase operational flexibility and profitability during variable demand
• Optimize on‑site power sources and capitalize on peak shaving to reduce demand charges
• Enhance conventional power plant flexibility and supply operating reserves
• Improve security and reliability of energy supply

Applications

• Marine and offshore: shipboard systems, drilling rigs, FPSO
• Newbuild and retrofit diesel‑electric power plants
• All‑electric and hybrid energy‑storage systems for industrial sites and grid support

Technology and system composition
Systems are engineered using design and simulation tools to match project requirements. The containerized BlueVault™ concept typically includes transformer, converter/inverter, battery management system (BMS) and modular battery racks. Integration focuses on thermal management, safety systems and controls to extend battery life and ensure reliable operation.
