Hithium signs 3 GWh long-duration storage deal with Brawn Capital

Chinese multinational Hithium has signed a deal with Brawn Capital to deliver 3 GWh of long-duration energy storage (LDES) capacity by 2030, alongside a slate of other project collaborations.

The deal with Asia-Pacific investor Brawn Capital covers multiple energy storage systems with different durations.

Long-duration energy storage appears to be an increasing focus for Hithium. The Chinese manufacturer entered a similar 2 GWh long-duration agreement recently reached with KNESS Group for the Ukranian market. Brawn Capital is expected to bring local expertise to the partnership, as a seasoned investor in Asia-Pacific renewables projects with offices in Hong Kong and Singapore

Announcing the Brawn Capital deal, Hithium revealed approximately 20 ultra-high voltage (UHV) projects have entered the preparation phase, while 300 MWh of energy storage projects are scheduled for delivery in 2027.

The cooperation agreement covers multiple energy storage system solutions of different durations, according to Hithium, including the manufacturer’s recently unveiled 10-foot “∞Power” Flexsso 3.125 MWh and 6.25 MWh energy storage system.

Hithium said the deal marks a “key step forward” for the business in the large-scale application of long-duration energy storage and the expansion of the Asia-Pacific market.

The Brawn Capital deal also follows Hithium’s decision to invest around €400 million ($458 million) in a Spanish battery factory. The March 2026 announcement saw Hithium commit to a join venture with public company Sodena to develop a facility that could be operational in early 2027.
