Bioelectrochemical reactor can be used for upgrading biogas that contains 60% methane to 90% methane. This improved methane can be used power more of the buses in Grenland. I have used the wastewater that comes out Karrdalstrand wastewater treatment plant to reduce 20% of COD that usually goes into the fjord. Additionally, methane production is also improved. This is done in laboratory for now, but can be easily scaled to be applied in KRA wihtout modifying the existing plant infrastructure. It can be done with very less electricity requirement.
The main aim of this technology is to use the electricity from wind and solar power in the rest rest of the world. There have been many reports in recent times that the electricity from wind and solar power are intermittent and unreliable. Sometimes the electricity is wasted due to overproduction and this excess electricity can be used for bioelectrochemical unit integration with biogas production processes.
