COSMO's Hydrogen Stations for a Decarbonized Society
Expanding Next-Generation Energy
Hydrogen is expected to serve as a next-generation energy source that emits no CO2 when burned. To help realize a decarbonized society, the Cosmo Energy Group has positioned hydrogen as a key pillar of future energy and is actively working toward its practical implementation.
Challenges in Societal Uptake and the Role Cosmo Plays
There are several barriers to the widespread adoption of hydrogen energy, such as the high price of fuel cell vehicles (FCVs), a lack of hydrogen stations, high costs, and problems with storage and transportation. At the Cosmo Energy Group, we are establishing and operating hydrogen stations under an alliance with Iwatani Corporation, contributing to the resolution of these challenges.
Partnership with Iwatani Corporation
We ensure the stable operation and steady deployment of hydrogen stations by combining the Cosmo Energy Group's infrastructure operation capabilities and sales network with Iwatani Corporation's hydrogen supply expertise.
To facilitate the design and operation of hydrogen stations, we have established a system that emphasizes safety and stable operations. At Iwatani Cosmo Hydrogen Station Heiwajima, we have maintained a near-100% operating rate, demonstrating a strong operational track record. Through these efforts, we aim to advance the practical implementation of hydrogen supply chains and commercialize our next-generation energy business.
Status of Hydrogen Station Deployment
The hydrogen stations operated by Iwatani Cosmo Hydrogen Station LLC, in which the Cosmo Energy Group holds a stake, come in various types tailored to different locations and uses. They also serve to validate the hydrogen station concept in preparation for wider use of hydrogen energy across society. Through the establishment of these stations, we are building hydrogen supply chains and accumulating operational expertise.

* Off-site supply refers to a hydrogen supply method where hydrogen is produced elsewhere (off-site) and transported to the hydrogen station by tanker truck or other means. Since no production equipment is required on-site, hydrogen station installation is relatively simple, making them well-suited for deployment in urban areas, transportation hubs, and other such locations.
Social Infrastructure Supporting Next-Generation Energy
The Cosmo Energy Group is working to develop hydrogen stations under an alliance with Iwatani Corporation, promoting the building of next-generation energy infrastructure that society requires. Aiming to generate annual ordinary profit of ¥10.0 billion in the next-generation energy field by 2030, the Group has positioned the hydrogen business as a core pillar of our operations.
Going forward, we will continue to expand the role of hydrogen stations as infrastructure supporting local communities and industries by ensuring safety and leveraging our operational expertise in stable supply, while also focusing on transitioning to green hydrogen produced from renewable energy and promoting human resource development. To realize a decarbonized society, the Cosmo Energy Group will steadily take steps to support the future of energy.
