Ballard Power Systems has signed an agreement to buy UK-based hydrogen power producer GeoPura Ltd., according to multiple reports. The deal is described as a strategic move by Ballard to expand its position in the hydrogen and zero-emission power market. One source says the combined transaction value is about US$400 million when accounting for cash, shares, and assumed debt, while another reports the purchase price as $515 million. The companies state that the acquisition is intended to provide Ballard with an entry point to the market for zero-emission backup power solutions. Both outlets frame the transaction as part of Ballard’s broader efforts to align its products with demand for hydrogen-powered systems that can serve as clean alternatives for backup and related power applications. The reports do not provide additional details on timing, regulatory approvals, or expected closing date.
