The company operates a Taoyuan Gigafactory in Taiwan, an R&D hub in Paris-Saclay, France (established in 2024), and is advancing a second gigafactory in Dunkirk, France, with Phase 1 targeting 4.0 GWh annual capacity by 2030.
ProLogium’s U.S. expansion is advancing through a May 2026 business combination with Translational Development Acquisition Corp. (NASDAQ: TDAC), with plans to list on Nasdaq under the ticker PRLG, pending SEC approvals. The investment underscores Kyushu Electric’s commitment to advancing battery technology for Japan’s electrification push, aligning with broader industry trends in solid-state and high-energy-density storage solutions.
