In 2005, the Japanese High-pressure Gas Safety Act, the Fire Service Act, and the Building Standards Act were revised to establish the requirements for 35 MPa hydrogen stations. And in 2012-2014, revisions were made to the High-pressure Gas Safety Act and the Fire Service Act to provide the regulatory requirements for 70 MPa hydrogen stations. We conducted a study on materials that may contribute to prepare technical standards concerning the major 4 items, 12 additional items and 13 new items which may affect the costs, from the point of view of promoting the hydrogen infrastructure.
