At NTT Analysis Improve 2026, I met the group behind NTT Anode Vitality’s analysis on hydrogen pipeline transportation. They confirmed me a bit of the resin-based pipe the corporate plans to insert into present underground telecom conduits, which helped me higher perceive how the know-how might be deployed.
Hydrogen is commonly introduced as a promising clear power supply, however transporting it safely and affordably remains to be a significant problem. It’s not a main gasoline supply within the traditional sense, however an power provider that may be produced from water, biomass, or fossil fuels. When utilized in gasoline cells to generate electrical energy, it produces solely water and warmth, not CO2, on the level of use, which is one purpose it stays central to many decarbonization plans.
That’s particularly related in Japan, which has been investing closely in hydrogen as a part of its longer-term push towards carbon neutrality, larger power safety, and industrial management in fuel-cell and hydrogen-related applied sciences.
NTT Anode Vitality is engaged on an answer that might assist decrease certainly one of hydrogen’s largest infrastructure limitations by utilizing present underground infrastructure reasonably than relying solely on newly constructed hydrogen pipelines.
The concept is to route hydrogen by means of resin-based pipes inserted into present utility or telecom ducts. That issues as a result of constructing new hydrogen pipelines is pricey, and the researchers defined that excavation is a significant a part of the associated fee. By avoiding large-scale digging, NTT believes it may make hydrogen supply extra sensible and more cost effective.
Security is a central a part of the challenge. Based on the corporate’s supplies and the researchers’ dialogue, the system combines hermetic transport pipes with monitoring applied sciences, together with strain and hydrogen sensors, in addition to optical-fiber-based leak detection. The group additionally mentioned the versatile pipe design makes it simpler to put in inside present underground pathways. Testing is already underway within the Tokyo space.
NTT tasks that the know-how may ultimately cut back preliminary prices by about half in contrast with standard steel-pipe provide strategies, whereas operating prices may fall by roughly one-third. The broader purpose is to assist a hydrogen provide chain that’s safer, extra scalable, and extra economically practical.
The know-how was additionally demonstrated at Expo 2025 Osaka, the place NTT put in a renewable-energy energy plant at its pavilion to supply hydrogen on website. That hydrogen-linked power was saved in a Panasonic gasoline cell and transported by means of a 200-meter underground pipeline from the NTT pavilion to the Panasonic Group pavilion, the place it powered LED lighting.
