Iwatani Corporation stands as a powerhouse in the hydrogen, LP gas, and helium markets, operating over 230 companies and employing more than 11,000 people globally. Since 1941, Iwatani has been a pioneer in the hydrogen industry, achieving significant innovations and leading the way in high-capacity transportation and storage solutions for liquid hydrogen. Their Advanced Hydrogen Technology Center in
Japan is a testament to their commitment to cutting-edge research and development in hydrogen technology.
The collaboration between New Cosmos Electric and Iwatani has a rich history of driving innovation and enhancing safety in the gas industry.
Key milestones include:
-
1969: Introduction of the world’s first residential gas leak alarm, "Mihari."
-
2014: Launching Japan's first commercial hydrogen station.
-
2025: Initiating the first commercial operation of a hydrogen-powered boat in Japan.
Challenge
To establish Japan's first hydrogen station, Iwatani worked alongside NEDO (New Energy and Industrial Technology Development Organization) and various industry players to carry out extensive demonstration projects. The insights gained from these projects played a crucial role in shaping vital safety regulations in the hydrogen sector. With these regulations in place, Iwatani turned to New Cosmos Electric, their trusted gas detection partner, to develop a comprehensive safety system that would meet the highest standards.
The Solution
New Cosmos Electric designed a complete end-to-end safety system for hydrogen fueling stations, featuring:
-
KD-12 II: A robust equipment monitoring system ensuring operational safety.
-
PD-12 II: Advanced leak detection technology for prompt identification of potential risks.
-
XP-3310II: Devices for measuring Lower Explosive Limits (LEL) to mitigate hazards.
Results
Since the implementation of New Cosmos Electric’s gas detection system at Iwatani’s hydrogen refueling stations, their technology has
become integral to all of Iwatani’s hydrogen stations. As of April 2025, there are 157 hydrogen stations operating in Japan, and New Cosmos
Electric's system is used in approximately 80% of these hydrogen stations nationwide.
-
Enhanced Safety: The gas detection system has effectively mitigated potential hazards by providing early warnings of hydrogen leaks, ensuring the safety of both personnel and customers.
-
Seamless Integration: Leveraging New Cosmos Electric’s extensive experience made it easy for Iwatani to implement the safety system with minimal disruptions, facilitating a smooth transition and ongoing protection.
-
Strengthened Brand Reputation: By focusing on safety and innovation, Iwatani has reinforced its position as a leader in the sustainable energy sector, demonstrating its dedication to advancing hydrogen technology.
This case study exemplifies how New Cosmos Electric's innovative safety solutions and collaborative approach can drive progress in the hydrogen energy market, underscoring the vital role of partnerships in creating a safer, more sustainable future.
Conclusion
The partnership between New Cosmos Electric and Iwatani Corporation highlights the transformative potential of innovative safety solutions in the hydrogen energy sector. By implementing advanced gas detection systems, Iwatani has not only enhanced the safety of its hydrogen fueling stations but has also set a benchmark for the entire industry.
As the demand for hydrogen energy continues to grow, the importance of robust safety measures cannot be overstated. This collaboration serves as a model for other companies looking to navigate the complexities of emerging energy markets while prioritizing safety and compliance with regulations.
Moving forward, New Cosmos Electric remains committed to supporting Iwatani and other industry players in their pursuit of safe, sustainable energy solutions. Together, they are creating a cleaner, greener future, solidifying their roles as leaders in the hydrogen economy.
