How much electricity does HKIA use?

Before the COVID-19 pandemic, annual electricity consumption of HKIA reached 299,760 MWh, with an electricity intensity of 3.99 kWh per passenger. Owing to the various development projects at HKIA, an increasing number of assets and systems will be commissioned, which inevitably leads to continuous growth of electricity demand.

Why does HKIA need a new emergency power capacity?

Owing to the various development projects at HKIA, an increasing number of assets and systems will be commissioned, which inevitably leads to continuous growth of electricity demand. Therefore, aside from the normal power supply, upgrading the existing emergency power capacity is critical to cope with increased essential loads in the future.

What is Bess – a high voltage battery energy storage system?

BESS is the first high voltage battery energy storage system in Hong Kong. Throughout the project stages from feasibility study and design to installation, testing and commissioning, the team has made concerted effort to liaise and coordinate with different parties such as power utilities, battery suppliers, experts and contractors.

Could a new generation of lithium-ion batteries be a workable solution?

A new generation of lithium-ion batteries developed by a team led by Dr Dong-Myeong Shin from the Department of Mechanical Engineering at the University of Hong Kong (HKU) paves the way for a workable solution.

Are lithium ion batteries safe?

Lithium-ion batteries have been the most commonly used batteries with their state-of-the-art energy storage technology. Currently, commercial battery technology mainly features liquid electrolytes and carbonaceous anodes, which has the drawbacks of safety issues, limited lifetime, and insufficient power density.

What is battery energy storage system (BESS)?

Overview of Battery Energy Storage System (BESS) Battery Energy Storage System (BESS) is an electrochemical type of energy storage system (ESS) that uses a group of rechargeable batteries to store electrical energy. Electrical energy is stored as chemical energy during charge and vice versa during discharge.
