The Oilholic arrived in Hong Kong from Singapore on Tuesday, took a break from market commentary on the Middle East crisis to head straight to The Battery Show Asia 2026. It is the world's leading battery exhibition and conference, that was held here from March 10 to 12 at the city's AsiaWorld-Expo, near the airport.
The event - co-located with Energy Storage Asia and Mobility Tech Asia - offered wide-ranging access to new markets for industry participants both large and small, cross-sector synergies, and high-value partnerships. It saw over 20,000 delegates and speakers - present company included - from 130-plus countries.
Alongside the content agenda spread over three days was an exhibition with over 350 exhibitors. What really impressed the Oilholic was the level of engagement across the entire energy storage, battery solutions deployment and recycling value chain.
Many industry facets were examined at the event, including a detailed examination of how the past year turned out. And the figures are pretty interesting.
In 2025, global annual capacity additions exceeded 100GW while the cost of lithium-ion battery pack dropped below $110/kWh. Additionally, looming large over the market is the dominance of one nation - China - which held just around 55% of all global capacity additions last year.
The market valuation - in US dollar terms - is pretty compelling too, and growing. Deploying various methodologies, major industry aggregators put the global battery energy storage system (BESS) market to have been in the range of $30-$50 billion in 2025. The Oilholic would say that even the lower end of that range points to a rapid China-led expansion.
As a special administrative region (SAR) of China and one of the world's leading centres of finance, Hong Kong is a major industry enabler with plenty of battery storage and technology related initial public offerings (or IPOs) making their mark on the Hong Kong Stock Exchange.
In 2025, the Hong Kong IPO market delivered a standout performance with nearly HK$ 300 billion (US$38.5 billion) raised across 100 listings, marking the strongest year in terms of funds raised on the HKEX since 2022.
This sterling performance put HKEX at the top of the global IPO list, with both US exchanges second and third, and the National Stock Exchange of India and the Shanghai Stock Exchange, securing the fourth and fifth places, respectively.
In a complete contrast, London dropped out of the top 20 managing only five IPOs and had a catastrophic year after falling even below post-financial crisis 2009 levels. A decent part of HKEX's outstanding performance was driven by battery storage and technology firms, something that's clearly reflected in the data, and the conversations the Oilholic has held over the past three days in Hong Kong.
