Okayama University's Helium Recycling Initiative

On May 15, 2026, a task force from Okayama University visited Yonago National College of Technology to implement a significant step in their regional collaboration project known as the Chugoku-Harima HeReNet. This project focuses on the recycling of helium gas, strengthening the shared research infrastructure across institutions. The initial phase of the project involved the collection of helium gas extracted from nuclear magnetic resonance (NMR) devices. The team included various technical staff members who collaborated effectively in executing this initiative.

The efforts to recycle helium began in December 2025, led by Eichi Hino, a technical professional at Yonago National College. His team has regularly collected helium gas accumulated in gas bags from the NMR unit, utilizing a compressor to transfer it into gas cylinders. During the event, approximately 90 liters of liquid helium prepared by Okayama University were transported to Yonago to fill their NMR device. This filling process took about an hour and signified a major milestone in phase two of helium supply within the HeReNet framework.

Hino expressed gratitude for the project's achievements, highlighting the importance of acquiring liquid helium at a lower cost amid rising prices. This initiative aligns with the Sustainable Development Goals (SDGs) by promoting responsible production and consumption. He emphasized the university's commitment to fostering a sustainable research environment moving forward.

Okayama University, recognized as a core regional research university, aims to expand the accessibility of liquid helium for a range of academic and industrial partners through initiatives like HeReNet and HeliGet. Given that Japan relies entirely on imports for its helium supply, this collaboration is also pivotal for economic security. Moreover, the university is developing a training program called HeliSET, which aims to cultivate future helium users and stabilize helium prices.

The helium recycling initiative will progress through several phases: first, collecting helium gas, followed by recovering and supplying a portion of it during phase two, and ultimately aiming for nearly all helium recovery and supply in phase three. This systematic approach will lay the groundwork for future operations.

“Engaging in projects like this not only enhances Japan’s research capabilities but also drives innovation,” stated university representatives. As Okayama University actively engages with partner institutions to elevate the nation’s research strength, they invite everyone to observe their journey toward a more resilient and sustainable research environment.

The impact of these efforts will strengthen local research capacities while ensuring economic security through reduced reliance on foreign helium supplies. The integration of HeReNet, HeliGet, and HeliSET into a cohesive project framework, termed the “He3 Project,” will continue to promote innovation in the field.

As Okayama University moves forward with these initiatives, they will remain dedicated to three core objectives: enhancing research collaboration, securing helium supplies, and contributing significantly to national economic development. This marks an exciting chapter for both Okayama University and its partners as they actively participate in critical efforts to improve research capabilities and instigate innovative solutions.
