UPSOM Methanation Reactor

What are the UPSOM systems?

The UPSOM is a new methanation technology with improved efficiency and reduced costs that directly converts carbon dioxide (CO2) and hydrogen (H4) into synthetic methane (CH4) via the Sabatier process.

Our proprietary methanation reactor converts green hydrogen and carbon dioxide into green methane. The only other by-products are water and heat that can be recovered and re-used.

Key facts and advantages


Cycle-resistant technology that enables a long service life and works with minimal maintenance.

Carbon neutral

Synthetic methane is a 100% carbon-neutral and renewable replacement for fossil natural gas.

Business case

The treatment of raw biogas with the UPSOM reactor is a sustainable business model with high potential.


The cost of the synthetic methane produced is competitive with biogas prices under many market conditions.

Advanced technology

Our systems are based on an innovative, patented technology.

Full conversion

Our patented reactor design reaches a conversion of over 99% in a single stage.
