Hong Kong does not make many batteries. It has no lithium mines, no gigafactories, and industrial land prices that would make any cell manufacturer wince. Yet Hong Kong Science and Technology Parks Corporation (HKSTP) wants the city counted among Asia’s premier energy storage ecosystems, and it has now published a report saying so.
The inaugural Battery and Energy Storage (BES) Strategic Analysis Report, unveiled today at One Earth Summit 2026 by HKSTP CEO Terry Wong, is less a case for manufacturing muscle than for middleman value. It argues that Hong Kong’s strength lies in a four-stage value chain spanning research, systems integration, green finance and end-of-life battery management.

It is a clever pitch. It is also a report written by the organisation that stands to benefit most from its conclusions, and it should be read that way.
The demand side is hard to argue with
The macro numbers are the least contentious part. According to the report, nearly 200 countries have pledged to expand renewables, with the goal of raising electricity’s share of global final energy demand from about 20 per cent today to 35 per cent by 2035. Electricity consumption from computing infrastructure is projected to more than double, from 415 terawatt-hours (TWh) in 2024 to 945 TWh by 2030. Investment in battery and storage technologies is expected to hit US$5 trillion (about HK$40 trillion) over the next decade.
That AI-driven power surge lands uncomfortably close to Southeast Asia. Johor, Batam and Greater Jakarta are absorbing hyperscale data centre builds faster than their grids can be cleaned up, a tension that threatens to blow a hole in ASEAN’s climate targets. Storage is the obvious bridge between intermittent solar and round-the-clock server farms, which is why Singapore has started putting money behind its own US$59 million grid fund.
The springboard pitch, and its limits
The report’s more strategic argument concerns China. Mainland firms account for more than half of the global battery applications market, and HKSTP positions Hong Kong as their preferred launchpad overseas. Three of the world’s top ten storage players, CATL, BYD and Gotion High-Tech, have “established a presence” in its ecosystem.
That phrase is doing a lot of work. The report does not say whether these are R&D centres, regional headquarters or registered entities, and the difference matters if the claim is about industrial depth.
The logic of the springboard also deserves scrutiny. As the US and Europe tighten rules on Chinese energy supply chains, HKSTP says mainland companies can lean on Hong Kong’s common law system, international certification and green finance platform to meet compliance requirements. Hong Kong can certainly help with paperwork, standards testing and capital. What it cannot do is change where a cell’s materials come from.
Washington stopped treating Hong Kong separately from mainland China for trade purposes in 2020, and Brussels’ battery rules trace carbon footprints and supply chain due diligence regardless of which city hosts the legal entity. Wong’s description of HKSTP as a “super-connector” is accurate; whether that connection survives the next round of trade tightening is another question.
Four stages, uneven weight
On research, the report points to five of the world’s top 100 universities and park companies such as Luquos Energy, a Chinese University of Hong Kong spin-off that claims to have built the world’s first sulphur-based flow battery. The company says it cuts costs and avoids the overheating fire risk of lithium-ion. Flow batteries are bulky and suited to stationary storage rather than vehicles, so this is a grid and building play, not an EV one.

Integration is where Hong Kong’s density becomes an asset. More than 60 per cent of the city’s private buildings are over 30 years old and face power capacity limits, making storage that charges off-peak and discharges at peak a practical retrofit. Park companies are also replacing diesel generators on construction sites, and Halo Energy has partnered with XPENG on what it calls the world’s first megawatt-level ultra-fast EV charging station in the city.
Finance is Hong Kong’s strongest card. The city is Asia’s largest arranger of green and sustainable debt, with related issuance topping US$76 billion in 2025. Considering how much of the US$37 billion promised to Southeast Asian climate projects has struggled to reach the ground, a finance-first hub has obvious appeal. HKSTP also signed an MoU this month with the Green Accelerator to link green tech startups with funding.
Recycling closes the loop. Hong Kong expects nearly 6,700 tonnes of retired EV batteries by 2030. Park company GRST has developed a non-toxic, water-soluble binder that it says cuts recycling-stage carbon emissions by up to 80 per cent, and the government opened the city’s first large-scale EV battery recycling facility last year. Southeast Asia faces the same wave sooner than it thinks: EVs are set to make up more than half of Singapore’s vehicle sales this year.
The neighbours are not standing still
Hong Kong is hardly the only city chasing this market. Shenzhen, a short train ride away, already has the factories. Singapore offers its own mix of green finance, rule of law and data centre demand. Indonesia has spent years using its nickel reserves to pull cell makers onshore, and Thailand has drawn Chinese carmakers, BYD among them, to build EV plants on its eastern seaboard. Vietnam’s VinFast, meanwhile, is betting on scale ahead of demand, with a 200,000-car plant for a 33,000-EV market in the Philippines.
Against that backdrop, Hong Kong’s edge is courts, capital and commercialisation rather than cells, the same final-mile-to-market argument it has made across other deep tech sectors.
The number to watch
HKSTP’s ecosystem currently has more than 250 green tech companies, around 100 of them in BES. It wants to lift that to over 160 in the next few years, a 60 per cent increase. The target is measurable, which is to its credit.

The harder test is whether the six companies HKSTP showcased at the summit, and those that follow, sell beyond the Greater Bay Area. Southeast Asia is the natural first market, yet Hong Kong founders have often looked north and west rather than south. If Hong Kong wants to be Asia’s battery broker, it will need to show up where Asia’s next grids are actually being built.
