Revolutionizing Energy Storage: CATL's Groundbreaking 9MWh TENER Stack Solution

CATL Unveils the TENER Stack: A New Era in Energy Storage

In a significant advancement for the energy sector, Contemporary Amperex Technology Co., Limited (CATL) has announced the launch of its TENER Stack, an ultra-large capacity energy storage system that boasts a remarkable 9MWh capacity. This innovative solution, which is set to commence mass production, was officially unveiled at ees Europe 2025 in Munich. The TENER Stack is designed to meet the increasing global energy demands triggered by surges in sectors such as AI-driven data centers and industrial electrification.

Meeting Growing Energy Demands

Increasing energy demands worldwide have necessitated efficient and flexible energy storage solutions. The TENER Stack responds to this challenge by offering a way for utilities, developers, and industrial entities to maximize economic returns from their installations. Amanda Xu, the CTO of CATL’s Energy Storage Solutions (ESS) division, emphasized CATL's commitment to leading the energy transition with this technology. She highlighted that, unlike traditional systems, TENER Stack ensures high energy density and a more manageable physical footprint, allowing for easier installation and operation.

Enhanced Performance Capabilities

The TENER Stack integrates high-energy-density battery cells featuring a five-year zero degradation technology, achieving 45% better volume utilization and a 50% increase in energy density when compared to standard 20-foot container systems. This significant internal capacity is capable of powering approximately 150 electric vehicles or supplying energy to the average German household for up to six years.

Moreover, the TENER Stack offers enhanced compatibility with both centralized and string Power Conversion Systems (PCS), thereby streamlining integration with existing infrastructure and expanding its potential applications across various grid systems. This technical prowess allows developers to expect a 20% reduction in overall construction costs, thanks to the system's space-saving properties and efficient deployment design.

Innovative Transport Solutions

One of the standout features of the TENER Stack is its design aimed at overcoming transport limitations. CATL has introduced a “two in one” configuration whereby each modular unit weighs less than 36 tonnes, adhering to transportation regulations across nearly all markets. This ensures that standard shipping methods can be utilized, cutting down on waiting times and specialized transport costs by up to 35%. The innovative structural design also enhances flexibility during transport, adapting well to routes with height restrictions, such as overpasses.

Advanced Safety Measures

With increasing concerns regarding fire safety in energy storage solutions, CATL’s TENER Stack adheres to high safety standards. The system leverages CATL's reliable lithium iron phosphate (LFP) battery technology, known for its thermal stability. Key enhancements include upgraded gas sensor technology that provides 40% better response times and a new triple-layer insulation that offers up to two hours of fire resistance. Furthermore, the TENER Stack meets stringent seismic standards, which ensures durability in extreme conditions, sheltering it against earthquakes and hurricanes alike.

A Broader Vision for Energy Solutions

By the end of November 2024, CATL's energy storage products had been crucial to over 1,700 projects globally across diverse climates and settings. The TENER Stack not only represents a significant leap over previous solutions like the TENER and TENER FLEX systems but also reinforces CATL's vision for the future of energy accessibility. Hank Zhao, the CTO of ESS Europe at CATL, asserted that with this stacked solution, the company is not just offering storage but a global energy solution that stands beside users during their energy transition journey.

Conclusion

The launch of the TENER Stack fundamentally alters the landscape of energy storage solutions. By combining enhanced capacity, innovative transport capabilities, and rigorous safety standards, CATL continues to be at the forefront of the energy industry, addressing both present needs and future challenges. As the energy landscape evolves, the TENER Stack is poised to play a pivotal role in the worldwide shift toward sustainable energy storage solutions, enabling greater efficiency in energy production and utilization.
