Hithium has signed a cooperation agreement for a potential 3GWh of battery storage deployments in the Asia-Pacific region with infrastructure investor Brawn Capital.
Chinese lithium-ion battery and energy storage systems manufacturer Hithium announced the strategic cooperation agreement yesterday (30 March). The company said the pair will focus on long-duration energy storage (LDES) and other projects in “key global renewable energy markets.”
The news comes a few months after Hithium’s launch of a 1,300Ah lithium battery cell dedicated to 8-hour long-duration applications, and Power8, an 8-hour BESS solution with 6.9MW output and 55.2MWh storage capacity per container.
However, it was not clear what sort of scope of LDES the new partnership will pursue, with Hithium’s release stating that the Hithium-Brawn partnership covers BESS solutions of varying duration, including the Chinese company’s ∞Power Flexsso 4-hour duration BESS, a 10-foot containerised system of 3.125MW/6.25MWh, designed to be compact and easily transportable.

Hithium said 300MWh of energy storage products are scheduled for delivery by 2027, with 20 ultra-high-voltage (UHV) projects in the “preparation phase.”
The 3GWh target has been set for the year 2030. Collaborator Brawn Capital is a private equity firm headquartered in Hong Kong, with offices also in Singapore. The investor claims to manage over 400MW of renewable energy capacity across technologies that include solar PV, energy storage and biomass gasification.
Brawn affiliate’s ‘100% merchant’ Japan BESS project
Brawn’s remit is to invest in renewable energy infrastructure in the APAC region that effects the reduction of greenhouse gas emissions (GHGs) in alignment with the UN Paris Agreement on Climate Change.
Its affiliates include Manoa Energy, a developer of high-voltage and extra-high-voltage battery energy storage system (BESS) projects based in Japan. In December last year, Energy-Storage.news reported that Manoa Energy and partner HD Renewable Energy (HDRE) had begun commercial operation of a 50MW/104MWh BESS project in Hokkaido, northern Japan.
At the time, the partners said the project, Helios 50MW, is a “100% merchant” asset, intended to stack revenues from participating in wholesale energy trading, balancing and capacity market opportunities.
After beginning day-ahead and intraday trading in the Japan Electric Power Exchange (JEPX), HDRE said was completing 48 transactions daily and expected to earn up to JP¥2 billion (US$12.8 million) revenue in power trading from its first year of operation.
Hithium said Brawn Capital will bring investment, project development and asset management capabilities to the partnership.
Hithium is thought to be making a resubmitted bid to list its shares via an IPO on the Hong Kong Stock Exchange (HKEX), following a trend of Chinese energy storage companies adding Hong Kong share (H-share) listings alongside mainland China exchange listings (A-shares).
As part of Energy-Storage.news’ annual Year in Review interview series at the beginning of this year, Hithium senior director of global business development Giriraj Rathore said the company expected 2026 to “mark a shift from rapid expansion to meaningful differentiation.”
“While the demand for energy storage remains strong globally, markets are becoming more structured, with higher expectations around localisation, bankability, and application-specific performance,” Rathore said.
