SHARING IDEAS THAT DO GOOD

Biogas to Hydrogen & Graphite

post-image

A Western Australian pilot project, thought to be a world-first, is taking biogas from sewage and splitting it into graphite and hydrogen.

The hydrogen can be used for industrial applications and the graphite for carbon black, activated carbon and battery anode applications. Both also tend to be higher-value commodities than the biogas.

The process uses an iron ore catalyst, creating an alternate hydrogen pathway to the traditional approaches of steam methane reforming and electrolysis.

Construction has been on-going for the demonstration project, with production of the first 100 tonnes of hydrogen hopefully due by the end of 2021.
