The ALT-BESS research project, led by KTH Royal Institute of Technology and approved by the Swedish Energy Agency, has entered its implementation phase. Kortrong Group, through its strategic partner EnBrilion, is participating as a project collaborator—providing long-term operational data and engineering validation support from its energy storage systems to underpin cutting-edge research with industrial practice.

01 Advancing Frontier Research, Integrating into Europe's Leading Research Network

ALT-BESS is led by KTH Royal Institute of Technology, in collaboration with Einar Mattsson AB, the University of Skövde, and EnBrilion. The project aims to develop integrated decision-making tools covering aging models, life cycle assessment (LCA), and techno-economic analysis (TEA). Kortrong Group, as a strategic partner of EnBrilion, has passed academic compliance reviews for its data governance systems and engineering validation capabilities, becoming a key data support node for the project.

This collaboration represents a model where Nordic energy storage research integrates operational data from industrial and commercial storage systems operating in China's complex power markets—transforming real-world engineering experience into empirical evidence for academic research. It embodies a deep integration of industry, academia, and application, helping fill the data gap in European markets for high-power, high-cycle C&I storage scenarios.

This marks Kortrong Group's entry into international research collaboration through data as a core asset, advancing the deep integration of industry, academia, and research, and strengthening practical international science and technology cooperation.

02 Enabling Technology Transfer, Adding New Dimensions to "Technology Going Global"

Sweden's energy storage market is expanding rapidly, driven by price arbitrage opportunities. However, the lack of systematic assessment of battery aging behavior, environmental impact, and safety risks under different operating conditions directly affects the credibility of long-term project profitability forecasts. In this context, the absence of real-world operational datasets under complex conditions represents a critical bottleneck for model validation.

The operational dataset provided by Kortrong Group for this research project covers capacity degradation trajectories across varying depths of discharge (DOD) and temperature cycles. This data will serve as training samples for ALT-BESS's AI prediction models and will be used to validate the residual value estimation module within the techno-economic analysis (TEA) framework, supporting model calibration across four assessment dimensions.

This "data-model-feedback" closed-loop validation helps shorten the lab-to-field gap—the distance between laboratory testing and commercial operation—and accelerates the translation of research outcomes into practical applications.

03 Deepening Collaborative Innovation, Advancing International Technical Standards Exchange

Participation in the ALT-BESS project marks a milestone where Kortrong Group's data governance outcomes are now integrated into Europe's frontier energy storage research network. By aligning real-world battery aging characteristics with LCA methodologies, this collaboration provides a data reference from Chinese operating environments for sustainable energy storage research in the Nordic market, while also building international expertise in full-lifecycle asset management for Chinese storage assets.

This cross-border research collaboration opens channels for Kortrong to engage in technical standards and assessment methodology exchange with European partners. Together, the consortium is working to provide more deterministic technical support for the global energy transition.
