Tsubame Plant Moves to Commercial Ammonia Production at Kashiwazaki
What happened
Tsubame's plant at Kashiwazaki Hydrogen Park has moved from trial operation to commercial production and supply to Yokohama, Japan. Inpex is utilizing Tsubame's electride catalyst technology for the Blue Hydrogen and Ammonia Production and Utilization Demonstration Project. Supply of ammonia from the plant to Mitsubishi Gas Chemical began on October 23, 2026.
