ESS Unveils 1.2 MWh Bridge Sodium-Ion Battery System

ESS Introduces Its Bridge Sodium-Ion Energy Storage Solution

According to НВ — Техно: On July 11 at 7:00 PM, ESS announced the launch of its Bridge sodium-ion system, engineered for utility companies, data centers, and critical infrastructure. This AC module, housed in a three-meter container, delivers an initial capacity of 1.2 MWh and can be scaled up to 4.8 MWh by stacking multiple units within a six-meter container footprint.

Designed to address the surging electricity demand driven by the expansion of computing platforms and artificial intelligence, the Bridge system has already attracted over $1 billion in commitments from early customers. This strong market interest highlights the growing need for innovative energy storage solutions.

Technical Advantages and Key Features

The Bridge system is a ready-to-use, plug-and-play solution. Installation requires only a forklift, and the module relies on simple air cooling. A major safety benefit is the elimination of thermal runaway and fire risks. The battery supports charge and discharge durations ranging from one hour to over 16 hours, operates in temperatures from -40 °C to 50 °C, and is projected to have a 20-year lifespan.

The system integrates:

• sodium-ion cells,
• an integrated power conversion system,
• cabling networks,
• and software designed to ensure efficiency and reliability in operation.

Notably, the Bridge system is built using abundant and widely available materials, which could help lower costs and improve accessibility for potential customers.

The deployment of ESS's Bridge sodium-ion system marks a significant step forward for renewable energy and energy storage technologies. With its flexible installation and operational capabilities, it is well-suited to meet the growing energy demands fueled by technological progress. The strong market response underscores ESS's potential to drive further innovation in energy storage, contributing to more stable and efficient power systems in the future.
