The UBESS initiative aims to repurpose used batteries into energy storage systems for efficient energy management
Category: Science
In a bold step toward sustainable energy solutions, Hyundai Motor Group has officially launched a pilot project to repurpose used electric vehicle (EV) batteries into energy storage systems (ESS). This initiative, known as the Used Battery Energy Storage System (UBESS), marks a first in South Korea, leveraging the used battery packs from Hyundai's Electric-Global Modular Platform (E-GMP) vehicles.
The UBESS project was announced on September 10, 2026, during a ceremony held at the Wonik P&E facility in Dongtan, Gyeonggi Province. The event was attended by key representatives from Hyundai Motor Group, LG Energy Solution, Hyundai Engineering, and Wonik P&E, highlighting the collaborative effort among these companies to explore innovative uses for EV batteries that have reached the end of their automotive life.
During the ceremony, the participating companies unveiled their plans for the UBESS project, which involves constructing a 200 kWh energy storage system. This system is integrated with EV fast chargers, allowing for the storage of electricity during off-peak hours when rates are lower, and utilizing that stored energy during peak hours when electricity costs are higher. This operational model aims to optimize charging infrastructure and seeks to establish a sustainable value creation system throughout the entire lifecycle of EV batteries.
The core of the UBESS initiative lies in its innovative approach to battery reuse. Rather than discarding EV batteries when they can no longer efficiently power vehicles, this project aims to extend their lifespan by repurposing them as energy storage units. This is particularly relevant as the demand for energy storage solutions continues to grow, driven by the increasing integration of renewable energy sources and the need for grid stability.
Hyundai Motor Group, along with its partners, will conduct comprehensive evaluations on the performance and safety of these used batteries in their new roles. This includes testing discharge and charge control algorithms, ensuring system reliability, and maintaining battery performance characteristics. These evaluations will be conducted in real-world operating environments, providing valuable insights into the feasibility and efficiency of the UBESS model.
The UBESS project is more than just a technological innovation; it is a step toward a circular economy in the battery industry. As the global push for electric vehicles intensifies, so too does the challenge of managing battery waste. By finding new applications for used batteries, Hyundai and its partners hope to reduce environmental impact and promote resource recycling. This initiative aligns with broader trends in the automotive industry, where companies are increasingly focused on sustainability and reducing carbon footprints.
Other automotive manufacturers have already begun similar initiatives. For example, Nissan has commercialized used batteries from its Leaf model for use in urban energy storage systems, demonstrating the viability of battery reuse in various applications. European manufacturers like BMW and Renault are also exploring energy storage projects that utilize repurposed batteries, underscoring a growing trend in the industry.
As the UBESS project progresses, the participating companies will monitor its outcomes closely to assess the technical and economic viability of using used batteries in energy storage applications. This includes evaluating the potential for scaling the project and integrating it with existing energy infrastructure. Future developments in this area could lead to expanded applications of used batteries not just in South Korea, but globally.
With the increasing number of EVs entering the market, the volume of used batteries is expected to rise significantly in the coming years. This makes the success of projects like UBESS critically important for establishing effective recycling and reuse strategies within the automotive sector. The results from this pilot project could set a precedent for how the industry approaches battery lifecycle management, influencing policies and practices worldwide.
In a statement, the participants expressed their commitment to verifying the potential for battery reuse and establishing a circular economy for batteries, stating, "We will comprehensively verify the feasibility of reusing used batteries and realize a battery circular economy to accelerate the zero-carbon era." This ambitious goal reflects the growing recognition of the need for sustainable practices in the face of climate change and resource scarcity.
As the UBESS initiative moves forward, it will serve as a litmus test for the future of battery recycling and energy storage solutions, potentially paving the way for new business models and environmental strategies in the automotive industry.
