Secretary for Environment & Ecology Tse Chin-wan visited Shenzhen today to learn more about its charging infrastructure.

Mr Tse first visited Huawei Digital Power Technologies to learn more about the company's latest developments on supercharging, energy storage, automatic charging for electric vehicles (EV) and the latest carbon reduction solutions offered to the market.

He then visited the Development & Reform Commission of Shenzhen Municipality to exchange views with commission officials and new energy enterprise representatives to better understand the latest developments of charging infrastructure in Shenzhen.

Mr Tse noted that Shenzhen's latest developments and successful experiences in EV charging facilities provide valuable references for Hong Kong and inspire new ideas for the future development of its charging facilities.

He also expressed the hope that Hong Kong and Shenzhen will continue to strengthen exchanges and co-operation to jointly promote ecological civilisation construction as well as regional green and low-carbon development in the Greater Bay Area.

In the afternoon, the environment chief toured the Lianhuashan Supercharging Station. This site integrates photovoltaic storage supercharging and vehicle-to-grid technology in one public supercharging demonstration station, with a maximum charging power of up to 600 kilowatts and supports high-power reverse discharge back to the grid.

Mr Tse also visited the government car park at the Futian District Committee Compound.

The project is a demonstration point that combines solar power generation, power storage and supercharging services. Integrating intelligent low-carbon technology, high-energy efficiency and architectural aesthetics, it is equipped with a liquid-cooled supercharging system and an intelligent energy storage system, generating an annual average solar power output of 500,000 kilowatt hours.

Mr Tse returned to Hong Kong this evening.
