Operations commence at world’s largest methanation test facility

Inpex Corp. and Osaka Gas have begun demonstration operations at what they describe as the world’s largest methanation test facility, advancing a joint project to develop CO2 methanation technology for carbon‑neutral city gas. The launch follows completion of construction and trial runs, marking a step toward practical implementation.

What do you think is the biggest hurdle to scaling CO2 methanation—securing low‑cost green hydrogen, reducing system costs, or integrating with existing gas grids?
