Powering the green transition: Why the global battery race runs through Hong Kong

The global battery race is accelerating, with investment in battery energy storage (BES) projected to reach US$5 trillion over the next decade. Hong Kong, as Asia's leading hub, is positioning itself as a launchpad for materials, integration, green finance, and recycling in this burgeoning industry. Hong Kong Science and Technology Parks Corporation (HKSTP) is driving this effort, highlighting the city's strong foundation in battery research, system integration, and smart power electronics.

At the upstream stage, Hong Kong's universities are leading research in solid-state batteries, water-based flow batteries, and carbon-nanotube current collectors. Companies like Luquos Energy are already developing innovative technologies, such as a water-based sulphur flow battery, which has cut electricity costs for EV-charging infrastructure.

The midstream stage involves system integration and smart power electronics, enabling applications ranging from mobile generators to fast EV charging. Hong Kong's green finance framework supports project rollouts, while international compliance ensures sustainability. The downstream stage focuses on battery recycling, with Hong Kong set to become a regional leader in EV-battery recycling, transforming retired batteries into recycled materials and enabling second-life applications.

This creates a circular economy, reducing reliance on virgin resources. Overall, Hong Kong's comprehensive BES ecosystem makes it an ideal launchpad for Southeast Asian founders in the green transition.
