Technology Overview

A porous, hydrophobic tubular membrane is used on the outside as base for a microbial film composed of hydrogen converting microorganisms that form a reaction between hydrogen and carbon dioxide to create a combustible gas: Methane.

Hydrogen and Carbon dioxide are fed from the inside of the porous membrane and is transported through the membrane by a small overpressure. In the microbial film the gases are feed for the microbes that gain energy from the conversion to methane.

Presently there is no laboratory or pilot plant to demonstrate the principle described in the patent, but a newly conducted simulation based on lab results show that the gross cost incl. depreciation amount to 0.35 $/kg SNG produced. The main cost is the supply of hydrogen.

Benefits

Close to 100% conversion of carbon dioxide to natural gas (no recycling needed).
Scalable as the membrane biofilm reactor is positioned separately and outside of the biogas reactor.
Access to the active part (the membrane) without the need for disassemble the system.
Easy service and maintenance and low cost operation.

Opportunity

SDU are looking for partners to build and test prototypes in 1:1 scale to proof upscaling.

SDU offer access to the protected technology via e.g. licensing.
