Japanese optical fiber leader Fujikura recently announced it is treating the current helium shortage as a “short-term” issue and is exploring ways to produce its own.
This might sound surprising, but it's a critical issue for our digital world. High-quality optical fibers, the backbone of the internet and AI infrastructure, are made using a special piece of equipment called a draw tower. This tower uses helium gas to rapidly cool the fiber as it's being produced, which is essential for achieving the purity and quality needed for high-speed data transmission. There are no easy substitutes for helium in this process that can maintain the same speed and quality.
So, what caused this shortage? The story begins with the recent conflict in Iran. First, this led to damage at the massive Ras Laffan gas facility in neighboring Qatar, one of the world's largest helium producers. Second, this single event instantly wiped out about a third of the global helium supply. Third, the market, which had been in a surplus, flipped to a severe shortage. As a result, spot prices for helium roughly doubled, and logistics costs soared.
Against this backdrop, Fujikura's plan to “produce” its own helium isn't about drilling for new gas fields. Instead, it's a clever strategy focused on resilience. The plan involves installing on-site helium recovery and recycling systems. These systems can capture the helium used in the draw towers and purify it for reuse, with vendors claiming recovery rates as high as 75-95%. While this requires a significant initial investment, it's a practical solution that can be implemented within months, aligning with their “short-term” view of the problem.
This move is also deeply connected to the AI boom. Fujikura is already planning major capacity expansions, including a new plant in Sakura and investments in the U.S., to meet the surging demand for optical fiber driven by AI data centers. To make these investments successful, securing a stable supply of essential materials like helium is non-negotiable. By announcing its self-supply plan, Fujikura is signaling to investors that it is proactively managing supply chain risks to capitalize on the AI-driven growth curve.
