Etica Battery has debuted its HVDC-based energy integration solution at Energy Taiwan 2025, showcasing a new approach to zero-risk battery energy storage for AI data centres and high-consumption industries.
The system features Etica’s patented LiquidShield™ immersion cooling technology and a modular BESS rack using Shell’s high fire point, non-hazardous ester liquid. This combination enhances fire safety and extends system life in demanding environments. By integrating UPS and BBU architectures, the solution delivers stable, efficient power for cloud service providers and AI server operators.
Etica’s HVDC architecture directly connects battery modules to the high-voltage data centre network, reducing conversion losses and improving response during load fluctuations. UPS provides millisecond-level protection, while the BESS offers two to eight hours of backup power.
“For Etica, safety is not an added feature; it is the core of our technology and mission,” said Gavin Wang, founder and chairman.
LiquidShield submerges cells in insulating coolant to suppress ignition, earning UL 9540 and NFPA 855 certification. Etica’s multi-tier protection ensures uninterrupted power for critical infrastructure, including data centres, hospitals, telecoms and manufacturing.
To date, Etica has deployed over 286MWh of energy storage across Taiwan and Japan. The company is expanding into the US, Southeast Asia and Saudi Arabia, supporting Taiwan’s net zero goals through partnerships with renewable developers.
“We’re not just building batteries model – we’re building a zero-risk energy world. Our long-standing collaboration with Shell also marks a key milestone in advancing sustainable energy solutions,” added Wang.
