Project of laboratories for demonstration experiments related to hydrogen production and its exhibition facility at the Fukushima Hydrogen Energy Research Field that became operational in 2020. Researchers from four companies in different industries come together to conduct research that transcends the boundaries of their respective companies. Spatial units, such as laboratories and exhibition rooms, are arranged continuously with surplus spaces, creating a variety of places for researchers and exhibition spaces in which the architecture is integrated. In contrast with the plant's inorganic appearance, the wooden exterior simply shows the wood's uneven colors, knots, and surface roughness, giving the impression that this is a place for renewable energy research. We hope this facility will be further utilized as a place for next-generation energy research.
