Austrian start-up company Krajete, based in Linz, has set up a process for the direct utilisation of all industrial CO2 sources. The innovative technology consists of a one-step synthesis of methane from carbon dioxide and hydrogen or electricity sources. The methanogenesis is performed by Archaea microorganisms through direct non-photosynthetic conversion and saves cost intensive up- and downstream processing units.
One of the main applications for the process lies in 4th generation biofuels as the technology does not rely on photosynthesis or biomass. The conversion of CO2 into methane for transportation is carbon neutral and faster compared to first, second and third generation biofuels. A second possibility for using the Krajete process lies in excess electricity storage through conversion of hydrogen into methane, but the technology can also enable the efficient upgrading of raw biogas from fermenters to natural gas. To estimate your business’ potential to use the Krajete technology, take the following test.
“Is CO2 a pollutant in nature? Not at all, […] everything is recycled. This simple concept triggered us to see if we can do the same that nature does – recycling CO2 into something useful – but outperforming it in terms of yield and productivity. Today, the Krajete CO2 to methane process can produce a high quality biofuel (biomethane) with a productivity that is at least 1.500 times faster than going biomass to biomethane through conventional biogas production processes.” Dr. Fabrizio Sibilla, Krajete Gmbh
