Tokyo, February 14, 2025 — Kawasaki Heavy Industries, Ltd. announced today its completion, with support from DNV,*1 of demonstration testing for greenhouse gas (GHG) emission calculation methods using data obtained from actual equipment including hydrogen production. Calculations were carried out using its “Suiso*2 Platform”, a digital management system, over the entire hydrogen supply chain, from production through to end-user delivery, and verifications confirmed that calculation methods aligned with international standards (ISO/TS 19870:2023) stipulating the methodology for calculating hydrogen’s CI*3.
Kawasaki conducted its hydrogen supply chain proof of concept testing with assistance from Obayashi Corporation, which manages a hydrogen production facility in Kokonoe-machi, Oita Prefecture for a project to verify the use of hydrogen produced using geothermal power, and from Eto Sangyo Co., Ltd., which manages transport of hydrogen from production sites as well as hydrogen refueling stations used by fuel cell vehicles (FCVs).
For the demonstration tests, hydrogen produced using electric power from a geothermal power plant was transferred to gas cylinder bundles,*4 transported by truck to a hydrogen station in Oita City, and then used for refueling FCVs. In this way, the testing process covered the entire supply chain, from production through to the phase directly prior to consumer usage. The testing involved identification of GHG emission sources and collection of various data—emission source data, including electricity consumption and gas cylinder bundle transport distances, and data related to hydrogen volumes—using sensors and documents. The collected data were then used to verify that the methods for calculating GHG emissions and hydrogen CI were aligned with international standards.
For purposes of creating a digital management system that visualizes hydrogen distribution operations, Kawasaki conducted verification of the following two services, which comprise the core system functions:
| • | Assessment and management of GHG emissions and carbon intensity |
| • | Ensured traceability by strengthening chain of custody through the digital management of attribute information such as hydrogen locations, and carbon intensity |
Based on the above two core services verified through these latest tests, Kawasaki plans to provide low-carbon hydrogen certification application support, assistance in hydrogen trading activities, and other such services, with the goal of commercial release of its platform around 2028. Moreover, through its platform and other projects, the company intends to forge alliances with other like-minded organizations to enable the early adoption of low-carbon hydrogen, while also contributing toward the practical application of hydrogen in society and realization of carbon neutrality on a global scale.
