Hydrogen storage alloy

Looking ahead to a society prioritizing the reduction of carbon emission, we established our hydrogen storage technology from an early stage.

We have a responsibility, as an enterprise that operates business in Japan, which consumes a significant amount of energy, to reduce reliance on finite resources and develop clean and renewable energy. In 1979, we started developing hydrogen storage alloys by applying our core technology. Subsequently, we successfully established hydrogen storage systems utilizing hydrogen storage alloys. These systems have been predominantly adopted for energy-saving and energy generation in buildings and factories. We are committed to continuing to promote sustainable energy businesses.
