Biological Methanation

The E-Fuel technology is based on the same technology we use for desulfurization, but with other bacteria and operating conditions. In the E-Fuel reactor CO₂ and H₂ is converted to CH₄. Methane can substitute natural gas and be used for decentralized heat and power production or injected into the natural gas grid. Methane can also be compressed to Bio CNG for heavy trucks or cooled down and liquified to Bio LNG for ships. Furthermore, methane can be processed to green fuel for aircrafts and green plastic for the industry in a GLT (Gas-To-Liquid) plant.

The Bio E-Fuel technology can be applied everywhere where you have a CO₂ source. However, biogas plants represent the lowest hanging fruit because the CO₂ flow and the infrastructure for methane production are already available. Biogas typically consists of 55-60% CH₄ and 40-45% CO₂. With Bio E-Fuel biogas plants can increase the methane content in biogas to +97-98%, i.e. the biogas production increases by up to 78%!

While biogas production and the associated H₂S removal is already an established and fast-growing industry methanation of CO₂ (carbon dioxide) with H₂ (hydrogen) to CH₄ (methane) is still awaiting implementation of regulatory framework for Power-To-G. Biogasclean will in summer 2023 start operation of its first full scale Bio E-Fuel plant.
