BYD plans to deploy the system in multiple gigawatt-scale projects by the end of 2025, including a 12.5 GWh installation in Saudi Arabia, with targeted expansion in Europe, Latin America, Africa, and Southeast Asia.

Future developments are aimed at further advancing sustainability and efficiency goals:

• Integration of liquid cooling and predictive maintenance.
• Development of hybrid solar-hydrogen-storage systems.
• A target of achieving over 95% system efficiency by 2026.

These advancements will continue to strengthen the system’s alignment with the SDGs, cementing its role in the global transition to a sustainable energy future.
