- Toray's trial with an all-carbon CO₂ and methane separation membrane showed a 70% cost reduction in moisture removal at a biogas facility.
- The trial took place over one year at a sewage plant in Osaka Prefecture.
- The technology aims to improve natural gas purification and CO₂ capture from industrial exhaust.
- Toray will present this technology at nano tech 2026 in Tokyo from January 28 to 30, 2026.
Trial Results
Toray Industries, Inc. has successfully completed a one-year trial of its all-carbon CO₂ and methane separation membrane at a biogas production facility in Osaka Prefecture. The trial demonstrated a 70% reduction in moisture removal costs compared to existing technologies.
Technology Overview
The all-carbon membrane is designed to resist chemicals and efficiently separate gases, targeting applications in natural gas and biogas purification, as well as CO₂ capture from industrial exhaust. Traditional polymer and zeolite membranes degrade when exposed to moisture, necessitating additional drying steps that increase costs and complicate scaling.
Future Applications
Toray aims to extend the use of this technology beyond biogas purification to streamline natural gas purification and enhance CO₂ separation and capture from industrial emissions. This aligns with global efforts to address energy shortages and decarbonization goals.
Upcoming Presentation
The company plans to showcase its innovative membrane technology at the nano tech 2026 event in Tokyo, scheduled from January 28 to 30, 2026.
